Everyday Things That Have Hidden Features You Didn’t Know

Flat Takeout Boxes

Who doesn’t love ordering some greasy Chinese takeout while binge-watching Netflix? We sure do. But, if you’re like most people, then chances are you’ve been eating your Chinese food wrong all these years. We’re talking about how you eat from the takeout boxes. Although there’s something satisfying in eating straight out of the container, you shouldn’t be doing this unless you are in a post-breakup.

The boxes can turn flat for a reason. This is because they are meant to be their own plate, and you don’t even have to remove the food from the container in order to convert it! Just carefully pull the sides apart and set it flat on the table. If you maneuverer it slowly and carefully enough, then your meal should now be sitting on a flat and convenient surface. So no need to dirty up the dishes!

Colored Squares On Toothpaste

Have you ever noticed that toothpaste tubes have a little colored block toward the bottom? This block may be blue, red, green, or black. If you think that this is there for the looks, you are wrong. And if you think that this tells you something about the product inside, you are also wrong.

These "eye marks" (a.k.a. colored blocks) are read by light beam sensors during manufacturing, and they tell the machines on the assembly line where to cut and fold the packaging. Without these marks, toothpaste would be connected to one another, making it rather difficult to put any toothpaste onto your toothbrush.

Arrow on Gas Gauge

Next to the gas gauge of most cars that have been manufactured since 2010, there's an arrow that either points to the left or to the right. This arrow indicates to the driver which side of the car the gas tank is on. If it's pointing to the left, that means that the gas tank gauge pointer is on the left-hand side of the vehicle and vice versa.

Most people don't need a reminder because they get used to filling their car up and instinctively know which side of the car to pull up to the gas pump. But if you ever have to drive a new car, such as a rental car, this is a good trick.

Loop in Back of Shirt

You've probably noticed that some men's shirts come with loops in the back of them. It was the Navy who first added this feature to the backs of men's shirts. When the men were out at sea, there wasn't much closet space. In order to save on space, sailors had loops on their shirts so that they could hang them up on hooks.

In the 1960s, the fad became popular among college students who used the loops while at the gym. Seeing an opportunity for profit, the Gant company started adding loops to the backs of their shirts in order to attract their Ivy League consumers. The loop became somewhat of a status symbol.

Metal at End of Measuring Tape

Have you ever noticed the small piece of metal at the end of the measuring tape (technically the beginning)? Most likely you have, but you haven't asked yourself what purpose it serves. There are actually several reasons why the metal is there.

To begin with, there's a little slot that can be placed around a nail to help hold the measuring tape in place in case somebody isn't around to hold the other end. You may have also noticed that the edge of the measuring tape is a bit serrated. The reason for this is so that it's easy to mark a wall or other surface in case you forgot that you put a pencil behind your ear to mark your measurement.

Dip in Wine Bottle

Most likely, you have noticed that wine bottles come with a dip at the bottom. Have you ever asked yourself what exactly the reason is for this? Well, to begin with, the dip, which is actually called a punt or a kick-up, prevents the bottle from falling over. You know when you have a picnic at the beach or outdoors and oftentimes the plates of food fly over and there's a storm of napkins in the air? And then all that strong wind comes trying to knock your bottle over.

The punt also exists in order to make the bottle stronger to hold up against higher pressure if there's champagne or sparkling wine inside. Finally, the punt makes it easier to distribute steam during the cleaning process before the wine is poured in. Although wine bottles are stronger nowadays, they are still manufactured with this indentation in the bottom to keep with the tradition.

Holes in Airplane Windows

Raise your hand if you freaked out a little the first time you sat in the window seat of an airplane and noticed a tiny hole in the window. We say this not to expose you, but rather to expose the purpose of that hole. This hole doesn't allude to the fact that the window of your seat is about to explode mid-flight. First of all, the hole is called the breather hole.

If you've ever wondered how you're able to breathe in an airplane when it's so high up in the air, well, the breather hole plays a part here. When an airplane climbs, air pressure drops outside. Thanks to plane manufacturers, the cabin remains at a safe and comfortable level. If it didn't, we wouldn't be able to fly. The breather makes it possible for the two outer panels of the aircraft to manage the pressure difference.

Holes in Padlock

Have you noticed that there's a tiny hole at the bottom of the padlock? These holes, as you should have already guessed, serve a purpose. First of all, the holes are there to drain water that has entered the lock. If this wasn't possible and the water couldn't drain out, then it could end up freezing and the lock would be prone to some serious damage.

A second purpose for these holes is to allow you to pour oil in the lock in case it gets jammed and won't open up, which would make the item useless. So, if that treasure chest you dug up as a child has been jammed for years, you now know how to open it and get your hands on the treasure!

Hole Next to iPhone Camera

If you use an iPhone then you may have noticed a little hole right next to the camera lens. If you're like most of us, then you most likely didn't pay it much attention as you probably use the selfie cam more anyways. It’s actually a microphone.

Since the iPhone 5 was released, all iPhones have included three microphones. One is right under the speaker grill, one is on the bottom edge of the phone, and the third one is right next to the camera lens. Because of the inclusion of three microphones, it's easy to pick up sounds no matter how you choose to hold your phone.

Keyboard Bumps

Take a glance at any computer keyboard. Do you notice two little bumps on the F and J keys? If you have ever taken a computer class, then you may have learned the reason why these bumps exist. But, if you're like the rest of us, you most likely don't have a clue. Well, the tiny bumps are there so that you can find your way on the keyboard while staring at the screen.

If you are typing with both hands, they will be aligned so that your left pointer finger is on F and your right pointer finger is on J. This allows you to keep your eyes on the screen while your fingers are typing away, knowing that your hands are in the correct positions.

Black Grating in Microwave

You've most likely noticed that a microwave comes with a type of black grating on its door. This grating is called a Faraday shield and it serves an important purpose. The shield prevents electromagnetic fields from exiting the microwave and causing harm to people hanging around the microwave waiting for their meal to heat up.

You should be thankful that the shield was there for you that time at 3 am when you were drunk, staring into the microwave, waiting for your pizza to warm up. Without the shield, you would be in harm's way and the microwave wouldn't be so effective at cooking your food. It does make you wonder, though, what exactly is happening to that food of ours inside of the microwave if it needs protection from electromagnetic fields?

Lines of Red Solo Cup

We've all drank out of red solo cups more times than we're willing to admit. We're not here to shame, we're just here to tell you something that your freshman year intoxicated self would have benefited from knowing. Did you ever notice that red solo cups come with horizontal lines inside of them? Well, those lines actually serve a purpose.

The lines tell you how much liquid is in the cup. So, the first line at the bottom of the cup equates to one ounce or one shot of hard alcohol. The next line is five ounces, which is the perfect amount for a glass of wine. The line at the top equals 12 ounces, which is the size of one beer. It seems like the red solo cup was on your side all along, and you didn't even know it.

Extra Holes in Sneakers

Unless you've been having your shoes tied for you since the time you were born, then you have most definitely noticed the extra hole at the top of your shoes that aren't being used by the laces. Have you ever questioned why they're there? The extra holes are there in the case that people get blisters on their feet and need to move their feet around inside of their shoe.

They can place their shoelaces in the extra holes but in the opposite direction. This creates a loop on each side, thus allowing you to cross your laces inside each loop. Then you can pull down on the laces to create a much tighter lock before tying your laces normally. This maneuver is called the “lace lock” or “heel lock,” and it helps make sure that your shoes remain tight to your feet.

Tab on Rear-view Mirror

You've most likely noticed that the rear-view mirror in your car includes a tab at the bottom of it. Even if you know that this black tab is there, this doesn't mean you know its purpose. Well, its purpose is to help you not die. The black little tab allows you to change the position of the mirror so that you can control the glare of lights behind you.

For example, you can tilt the mirror to reduce the brightness of the headlights of the car behind you. The tab allows you to manually do this. It works at deflecting light without preventing you from seeing that there’s a car behind you. It’s a very overlooked safety feature in cars. These types of mirrors were introduced in the 1930s, and by the 1970s, they were standard equipment in most cars and trucks.

Square Patch on Backpacks

A lot of people love toting vintage-looking backpacks that have a patch-shaped square on them. They are very popular. But, did you know that they actually serve a purpose other than looking cool and vintage? Called a "lash tab" or "pig snout" (you can imagine why), this patch was originally designed for travel packs to allow people to carry extra gear on their backpacks.

Cords and strings can fit through the two tabs of the patches, allowing wearers to hang extra stuff on the front of the bag. This especially comes in handy if you go camping and need to carry extra supplies to fasten them to your pack. While you probably aren't doing much hiking with this backpack, at least you know that you can hang stuff on the outside in case the need ever comes about!

Plastic Lids on Cups

You will probably gawk at this next one and slap yourself for never having realized this. The plastic lid that comes along with your disposable cup can also be used as a coaster, both for coffee cups and soda beverages.

Of course, when you're walking or in the car, you will keep the lid on. But when you sit down to enjoy your caffeine kick, the ridges of the lid are designed to grip your cup and hold it in place. Anyways, now we know better than to indulge in plastic lids... looks like you missed out on the opportunity.

Randomly Placed Buttons on Jeans

If you wear jeans often, then you have most likely noticed all the extra buttons scattered around the pockets of your pants. These buttons, which are technically called rivets, are strategically placed on the jeans to prevent them from getting worn out at the seams and ripping. Imagine your jeans ripping in the middle of an event or a holiday dinner after eating that decadent chocolate cake.

Jean tycoon Levi Strauss has ownership of these rivets, and they have a patent over them. They were introduced in 1829 after miners started to complain about their jeans wearing out very fast. So, young Mr. Strauss started thinking and came up with this product. They help jeans practically last forever. Next time you're out shopping for your next pair of jeans, just make sure that the ones you're purchasing have these bad boys on them.

Loops on Grocery Carts

Have you ever stopped and taken a moment to examine the design of a grocery cart? Take a look at the picture. Do you see those metal loops that jut out of the fold-out section of carts? This protects the products in your cart.

You can use the loops to hang plastic bags that are carrying breakable items like eggs and soft items like bread that you don’t want to get squashed by heavier items. The designer of the grocery cart was clearly well beyond their years. In fact, if you ever check out people who bag your groceries and put them in your cart, they themselves might not even be aware of this interesting function. Next time you can teach them something new and become the most likable person in the whole store.

Golf Ball Dimples

If you've ever gotten up close and personal with a golf ball, then you've noticed that its exterior is covered in dozens of little dimples. Golf balls weren't always this way. What happened is that experienced golfers started to notice that, over time, the older balls that had bumps and nicks would travel further.

These imperfections help create turbulence in the air around the ball, which then helps to reduce drag. Eventually, manufacturers began to design golf balls with these dimples already intact so that the balls get more lift and reach greater distances.

Margins on Lined Paper

You've used notebook paper thousands of times. But have you ever asked yourself why they look the way that they do? And how come when you get to college, do you have more space on the page? Well, the answer to the second question is obvious- colleges like to torture. But the answer to the first question is a little more fascinating and involves traveling back in time.

Years ago, when rats were frequently found in homes, they would chew on paper. Thanks to the margins on paper, a rat could nibble around the edges without destroying somebody's work and taking a bite of important information. So back then, kids couldn't use the excuse, "a rat ate my homework." While this feature isn't so necessary anymore, it's a little bit of history that has been maintained. Plus, the edges of our papers often get soiled, so it's a good thing that they're there.

Holes in Pot Handle

Unless you're a chef, you may not know the reason why pots and pans have holes at the end of the handle. Well, there are two logical reasons behind the existence of the hole. First of all, the hole makes it easy to hang the pot up on hooks when it's drying out or not being used. You may even have used pots that way plenty of times in your kitchen. But, the other trick of the trade is perhaps something that you haven't tried to do, and you're going to love it.

It's time to stop dirtying up the counter with the saucy stirring spoon. Next time you're whipping up a red curry in your pot, slip the utensil into the pot and let it rest there while your meal is cooking. You should especially try out this slick move the next time you make a meal and want to impress people with your talented Top Chef skills. Your performance is guaranteed to get many 'oohs' and 'aahs.'

Cylinder Toward End of Cable Cord

There are many different reasons to use a cable or power cord of some kind, so there's a good chance you've used one before. Well, if you have, you may have noticed a big cylinder-shaped lump toward the end of the cord. There is actually a name for this, other than a cylinder-shaped lump. These things are called chokes or ferrite cores.

It's simply magnetic iron oxide that helps to prevent any high-frequency electromagnetic interference. You know when your cell phone gets too close to a speaker, and you get that weird static noise interrupting your call? That's an example of this kind of interference. So, cable cords come with big cylinders to prevent that from happening.

Wings on Apple Power Cord

Are you a MacBook user? If so, you've probably noticed that there are some wings you can pull up on the power cord. You may have been confused as to what the purpose of these things is.

If you flip up the wings, it is much easier to wrap the cord around the power block so as to prevent it from being in the way. It's not necessary to use, but it is a neat little feature designed to improve your experience.

Paper Condiment Cups

We've all used those tiny (and, may we add, pathetic) paper condiment cups to dip our french fries and chicken fingers into. You know, those minuscule ones that you dip two fries into, and BAM, the ketchup is already gone. And let's not even get started with trying to dip your fat chicken wings into those little suckers.

But we are going to explain to you how to really use them so you can be the coolest kid in your chicken wing and fries crew. These tiny cups are also meant to be unfolded and treated like a plate. Never struggle again with trying to dip a fat wing into those.

Pocket in Women’s Underwear

Hey ladies, have you ever noticed that you have secret little pockets that are sewn right into your underwear? Well, there is a name for this little flap and it's called a panty gusset. Gussets are often made of moisture-wicking breathable fabrics like cotton to keep the privates dry and ventilated.

Most manufacturers don't bother stitching these closed. Anyways, it's actually more comfortable left open.

Zigzag Side of Bobby Pins

Even if you've never used a bobby pin, then you can still probably picture how one looks in your hair. One side is straight, and the other is wavy. The wavy zigzag side is the one that faces towards the scalp thus it isn't seen.

The wavy side is actually what helps keep the pin in place by helping catch the hair. That’s why you only see the wavy side when the bobby pin isn’t in use.

Soda Can Tab

Most of us are familiar with the top of a soda can like the back of our hands. Despite having drunk soda hundreds, and probably thousands of times in your life, you may have overlooked one feature of the soda can tab. Besides occasionally breaking off into the can and ruining the rest of your drink, the tab actually serves another purpose.

The tab on top of soda cans was actually designed to be flipped over again and used as a holder to keep your straw in place. Who knew, right? Despite this neat little addition, most of us refrain from using straws when drinking from a can, if not for the environment, then because they're so flimsy inside of the can and it's more comfortable to drink straight out of the can. But if you think about it, using the tab to hold your straw in place makes perfect sense.

Hole in Cap of Ballpoint Pens

All of us have used ballpoint pens throughout our grade school years. Did you ever ask yourself why the cap has a hole in it? Well, that hole was strategically placed there by the company. Nope, it's not so that it dries out faster, thus forcing you to buy more pens. The hole in the top is there in case a child or adult accidentally swallows the cap. If this happens, then thanks to the hole, air can flow through the cap, and the poor fellow who swallowed the cap can still breathe.

If you think to yourself, what kind of adult swallows the top of a pen, remember, many adults have the bad habit of putting pen caps in their mouth. It just takes one bad move until you accidentally choke on the cap. You're welcome to keep your conspiracy theories about companies drying out pens on purpose but just know that the company actually had your safety in mind when they engineered the pen.

Discs Under Bottle Caps

You have probably noticed at one point or another that under the cap of a plastic bottle of soda lies a little plastic disc. While you may not think anything of it (why would you?), there is actually a very interesting reason for it being there. That little plastic disc somehow helps to keep in carbonation.

Thanks to those little discs, we are gifted with fizzy soda and not flat. Nobody wants to live in a world of flat sodas. Gross.

Blue Part of the Eraser

You may think that some erasers are different colors simply to make them more appealing to children. In schools, there are even rumors among children that the blue part of the eraser could emit ink. Unfortunately, that isn't true. But, equally as cool, the blue part is meant to be used on certain types of paper that are thicker and stronger than common loose-leaf or notebook paper.

For example, artists use paper that is more sensitive to friction. For this reason, they need to use a specific type of eraser, in opposition to the pink erases that we common folk use.

Long Neck Bottles

For those among us who enjoy having an adult beverage, have you ever asked yourself why your alcoholic beverage often comes in bottles with long necks? Most likely, you've been more concerned with drinking the liquid courage and not interested in its history. Well, for one, the long neck of a beer bottle makes it comfortable to hold for long periods of time. It also makes it easier to pour into the ice-cold glass you had prepping for an hour in the freezer.

Some bottles have a more bulbous neck to help collect particles and sediment in unfiltered beers. And for yet another reason, the long necks also help distribute heat throughout the entire bottle when your warm hand is around it. In short, the long neck assures that your drink stays cold for as long as possible... which is what you want, right?

Pom-Poms on Winter Hats

When you went searching for a winter hat to handle the freezing temperatures of winter, you may have opted for one with a cute little furry pom-pom that sits on the top. While this is a fashion trend for those living in cold temperatures, the trend actually originates back to sub-zero Scandinavia where people have been rocking this look year-round since the age of the Vikings! The first sign of the pom-pom was on the Viking god Freyr. A statuette of Freyr was found in which he was shown wearing a hat or helmet with a pom-pom on top of it.

The word pom-pom dates back to the 18th century. It comes from the French word 'pompon', which is a small ball made from fabric or feathers. The pom-pom was ideal for heavier larger trinkets that soldiers in those times had been using. Instead, the pom-pom could be made inexpensively from scraps of yarn. People everywhere fell in love with the fluffiness and color of the pom-pom, and just like that, it has stuck throughout centuries.

Wooden Coat Hangers

Is your closet full of wooden coat hangers, plastic ones, or a mish-mash of both? Hangers can say a lot about an individual. But did you know why wooden hangers exist, to begin with? They are designed to keep away moths and other creatures that would damage your clothes. Heavy clothing, like coats and dresses made out of wool, is more vulnerable to various insects.

Wooden hangers are made from cedar wood which is known to naturally help repel moths and other bugs. It also absorbs moisture and odors. So, if you find that bugs are attracted to the clothes in your closet, you know how to take care of the problem!

Color-Coded Ice Cream Scoops

Some have worked in an ice cream shop for several years and never once understood why the ice cream scoops had different colors. Each color represents a different-sized scoop. Whoops, guess I messed up one too many orders. No wonder why my customers were always so happy...

Ice cream scoops can be given in over a dozen different sizes. This is based on how many scoops go in a cup and how many scoops fill up a 32-ounce container. While the rainbow colors of the handles look joyful and cute, they serve a purpose other than making you feel warm and happy inside.

Flaps on Juice Boxes

How could we have been doing something so simple, so wrong, for our entire childhood? If you're lucky enough, your parents at least mentioned something about those flaps being there. Instead, I was left with juice on my hands and a half-empty juice box after wrongly holding the box by its middle, which caused the juice to gush out of the straw. The horror.

Those flaps are meant to be turned outward to prevent this from happening. Easy to transport? Check. Spill-proof? Check. My whole life has been a lie? Double-check. Now that I know that the bulky flaps can be folded outward to make it easier for small-handed children to hold them, there's no way I will let another child suffer from ignorance the way that I did.

Ridges on Coins

We aren't sure if you've noticed this, but both quarters and dimes have rough edges (as opposed to pennies and nickels, which don't). To set the scene, the year is 1972, and the Coinage Act has just established the U.S. Mint. Back then, coins were stamped in different weights to show the real value of the coin.

In order to prevent criminals from filing shavings from the sides of the coins and selling the metal, minters put ridges on coins (a process known as reeding) to make it easy to tell if the edges had been shaved off. Another benefit to doing this was that it also made it more difficult to counterfeit the money. Nowadays, coins are no longer made from precious metals so this isn't an issue. But, we still have edges on our coins.

Detachable Headrests in Cars

This next one is up for debate. Do you know how the tops of the seat in a car are detachable? Come on, I know I'm not the only one that used to pull them out on family road trips and get my dad mad. If you think that there isn't a reason for this, then you're wrong. Well, there's a popular meme that went around explaining the reason for this madness. This meme explained that the reason for the tops of seats being removable is in case of an emergency.

If you're stuck in your car, you can pull out the headrest and use the metal bars to break through the window and exit the car. While they are really there to provide support for your head and neck in case of an accident, it does make you wonder why the headrests are removable. I'm choosing to believe that all those times I spent pulling the headrest out were practical and that I'll be the one who knows what to do when trapped inside of a vehicle.

Extra Fabric with Clothing

You've probably noticed when changing your clothes, that a lot of them come with an extra patch of fabric inside. If anything, you've thought to yourself that the fabric is there in the case that your shirt or pants rip and you need to do some sewing. Well, it's not there in the chance that your pants rip, although we suppose that you can use it as such if your shirt does rip (note that this might look very obvious unless you're a professional seamstress).

The little fabric's true purpose is to allow you to test out washing the material a certain way, so you know if it'll shrink or if the colors will bleed. This addition, which is nothing short of genius, lets you know how the clothing item will react in the machine. If you're hitting yourself now, just remembering the last time you ruined a new shirt, don't feel so bad.

Three Handles on Jerry Can

Jerrycans were designed in Germany in the 1930s for military use. The original design of the jerrycan still remains in widespread military use. The three handles were designed because it was specified that a soldier should be able to carry two full containers or four empty ones by holding onto the outer handle. In order to keep the fuel evenly distributed while you're holding it, there are three handles across the top.

This is especially true if two people are carrying it. If you are holding it with a friend, you should each grab one of the outer handles. If you're Hercules enough to carry it on your own, then grab it by its middle handle, or if you're carrying two in each hand, then by its outer left and right handles, respectively.

Brass Doorknobs

Alright, we definitely aren't expecting you to be paying attention to brass doorknobs, so if you haven't noticed this next one, then you get a free pass. All doorknobs are made out of brass. There is a very smart reason for the doorknobs being made from this, and it is surely not an accident. Things made from brass hold up better against bacteria build-up. Think of the number of times a day that doorknobs are touched.

The brass helps make them free of germs. This is very important, considering that people are constantly touching doorknobs after touching a load of other things. Obviously, this is important since people will pick up germs on their hands in countless different ways. Thanks to the brass, we are less exposed to germs than if they had been made from another material.

The Fifth Pocket on Your Jeans

Surely, you've noticed that little pocket on the side of your jeans, and while you probably just chucked its existence up to a design choice, and use the tiny compartment for storing folded cash or your trusty lip balm, this fifth pocket actually has a purpose.

Jeans used to be the preferred type of pants for cowboys and gold miners during the mid-1800s, and one of the most valuable items they carried around with them was their pocket watch. The tiny pocket was designed to keep their expensive and delicate pocket watches free from harm while they worked.

The Hole in a Pasta Spoon

Have you ever noticed the big hole in the middle of your pasta spoon? Even if you're not a big fan of Italian food, you must have seen these spoons at least once in your life and wondered why on earth would a spoon have a huge, weird hole going through it. As it turns out, there's a very simple and neat reason behind it - to help you calculate the exact amount of pasta you need for a single serving.

So, next time you're cooking just for yourself and don't want to overdo it with the carbonara, just take a handful of dry noodles and fit them through the spoon hole to make sure you have the right portion.

The Half-Belt on Coats

The half-belt is a clothing feature commonly seen on pea coats or trench coats, and certain types of jackets, and while you might think this is purely a fashion choice - like "pre-torn" jeans - the half-belt has an actual purpose.

Originally, the half-belt was invented for men serving in the military who had oversized jackets that they also used as blankets. The belt was used to gather and hold any extra material so the soldiers could walk around freely.

Utility Blades

Nowadays, you'd be hard-pressed to find someone that doesn't keep a box cutter or utility knife in the house. Whether this useful tool is something you use on a regular basis or something that mostly sits in a drawer gathering dust, this hidden use of a utility blade will surely come in handy. You may have noticed that utility knives come with a thick, plastic cap at the end and that the blades have little score lines.

The score lines are to indicate where exactly to break off the blade so you can have a fresh, sharp, new blade whenever you want. And the plastic cap is there so you can take it off and use it to cut off the blade! It's easy, safe, and helps you avoid nasty cuts.

Cream Tube Caps

While many of you might already know this one, it's still worth mentioning for those who haven't made this great little discovery. You've probably noticed that some cream tubes have spikes on the top of their caps, and if you're as curious as us, you probably wondered what they're for. Well, wonder no more.

These spikes are there so you can use them to pierce through the protective foil of your new tube! Simply unscrew the cap, flip it upside down, and use the spike to punch through the foil.

The Holes in Rulers

Rulers are a staple in any respectable pencil case and usually a tool that can be found in any household. While the purpose of a ruler is pretty straightforward, there is still one thing that many people wonder - why is there a hole in them?

Surely, you've noticed that many rules have a small hole on one of the ends, and as it turns out, the purpose of these holes is so you can hang the ruler up and have it handy whenever you need it!

The Lid on Tic Tac Packages

Everybody loves Tic Tacs. And even if you don't, there's still a 99 percent chance you've tried them at least once in your life. If you've ever opened one of those cute little boxes where Tic Tacs come in, you've probably realized there's a small indentation on the lid. The first thing that comes to mind is that it has something to do with keeping the plastic box tightly sealed.

While this is definitely the case, the indentation serves another purpose as a dispenser that gives you your Tic Tacs one at a time. Just shake the box upside down, put it back upright, open the lid, and you'll see there's a Tic Tac that fits perfectly in that indentation, just waiting to be grabbed!

The Metal Plates on Staplers

If you've ever worked in an office, you're probably incredibly familiar with staplers (and how infuriating it can be when it's stuck). If so, you've definitely noticed the metal plate they have at the front end, and probably assumed it was there as reinforcement to bend the staples. While this is, in fact, one of its functions, it's certainly not the only one.

Your average stapler actually has settings, and that metal plate, called an anvil, helps you adjust them. If you turn your stapler upside down, you can change the setting by spinning the wheel until it is lined up with the hole in the metal plate. This will turn the arms of your staple outward and make it much easier to pull out the staple later if you need to, like a "temporary staple."

The Hole on the Top of a Lollipop Stick

Lollipops will forever remain a childhood favorite. No kids' party was complete without them, and one of the best parts of eating a lollipop was turning the plastic stick with a hole into a makeshift whistle. As fun as that was, that hole actually has a purpose.

When candy makers pour the hot, melted candy into the mold, some of it drips into the hole and hardens, so the candy stays on the stick without falling off and becoming a choking hazard.

The Threaded Bands on Audio Jacks

If you were to look closely at an audio jack, you'd notice it has deep ridges. These bands are there so it's a tighter fit when the jacks are plugged in, but this is just one of their functions.

The threaded bands are made of an insulating material that protects the wires when sound is being transmitted. What's more, the number of ridges on a jack will tell you which end goes where on the sound equipment.

Silica Gel Packets

Everybody knows that silica gel packs are there to preserve a product's "freshness." But have you ever wondered how this little bag of tiny beads manages to do that? Silica gel sucks the moisture out of its environment, and they absorb up to 50% of the humidity in an enclosed environment, helping keep things nice and dry.

Next time you buy a new product that has one of these little packets, save it instead of throwing it out — next time your phone falls in the toilet, you can quickly shove it into a handful of these little beads. Definitely works better than rice, and is far less messy!

Rubber Bumps on Your Tires

Chances are that if you're not a mechanic, you probably have no idea these even exist. And why would you? It's not like we go around checking our tires every day. But if you did, you would notice there are little rubber bumps on the tread of your tire.

These raised edges inside the indentations of your tire's tread indicate when it's time to change tires; if the edges are even with the bumps, you should get to the tire shop, fast. If the edges are well above that of the bumps, you're good to go.

The Stripes in Your Toothpaste

If you've ever bought a tube of Aquafresh toothpaste, you've definitely noticed that the toothpaste has multicolored stripes. And no, despite the fact that the stripes are red, white, and blue, this has nothing to do with patriotism. Back in the 70s, people started to notice that brushing their teeth wasn't enough to keep bad breath away for long periods of time.

So, toothpaste makers added an ingredient (the blue stripe), whose sole purpose was to act as a breath freshener. Then, when people started to get concerned about the health of their gums, they added the red stripe, which is meant to control plaque. Multicolored stripes became a huge seller, and with time, many other toothpaste brands followed suit.

Women's Shirt Buttons

You would be surprised to learn about buttons on a woman’s shirt. Not only do they keep your clothes closed tight, but their position on your shirt — whether they are on the right or left, is symbolic of social status.

That’s right! Back in the day, buttons on the right would indicate that you might have been a farmer or ‘commoner’ because chances are you were dressing yourself. Buttons placed on the left, however, told the world that you were upper-class and most likely dressed by servants.

The Blue Bristles on a Toothbrush

It might look like your toothbrush is divided into colors for no real reason other than looking cool. But it’s actually not the case. The reason they color a part of the toothbrush blue is actually for an incredibly practical purpose. The blue bristles start to lose their color right around the same time one needs a new toothbrush.

So, essentially, the faded color is a reminder to go out and buy a new one. We do think that this should be made a little more public though; there are probably tons of people unknowingly holding onto faded and soft-bristled toothbrushes, wondering when they should buy a new one.

The Square Hole on the McFlurry Spoon

McDonald's ruined many a person's diet when it introduced the scrumptious McFlurry ice cream. If you've ever had the pleasure of enjoying one of these, you definitely noticed that they give it to you with a very weird-looking spoon.

The McFlurry spoon has a square-shaped hole through its handle, and it's actually used as an attachment to the machine that mixes the ice cream and toppings together. The machine's bar slips into the spoon and stirs it thoroughly. The only reason they give you the spoon with it is to minimize the mess. Pretty neat, right?

Order of the Letters on a Keyboard

Keyboard creators must have a good reason to not arrange those letters alphabetically. Not doing this seems pretty counterintuitive. Well, there is a reason for this, and surprisingly, it didn't start out like that. The first keyboard did, in fact, have letters that were arranged alphabetically.

But since typewriters were once clunky devices with metal arms, expert typists would type too fast and inevitably jam the keys over overly-quick usage. As a result of this, keyboard manufacturers decided to randomize the order of keys, thus slowing down the typists and giving each letter a little ‘break’. By now, the world is far too used to the order of the letters, so it doesn’t look like we’re planning on going back anytime soon.

The Second Hole on a Jerrycan

If you've ever had to fill up a gas can for a lawnmower, or any other machine for that matter, you might have noticed that the jerrycan has two holes with caps on them. So, what is that second, smaller hole for?

The second hole is actually there for safety. You're meant to remove the cap before pouring the gas in order to prevent "glugging," which would cause an unnecessary waste of fuel and potential fire hazard if it spilled.

The Dent on a Milk Jug

As you're probably well aware by now, milk jugs usually have a dent on one of the sides. And while many people will just chuck it up to a design decision, there is a purpose to this dent.

One of its purposes is to expand if there is a gas build-up, letting you know when the milk is spoiled. Another reason for this weird dent is to prevent the jug from exploding if it is dropped by mistake. The dent gives the jug expansion space that dissipates the sudden pressure that happens upon dropping the jug.

The Little Hole on Elevator Doors

If you ever thought that little hole on elevator doors was a secret spy camera, you'd be just like the rest of us. And just like the rest of us, you'd be wrong.

That little inconspicuous, odd hole on elevator doors is there in case the doors get stuck and need to be opened manually. It's official, our days of thinking we're being spied on by the elevator are over.

Flower Pot Holes

If you're trying to add more greenery to your space, you've probably come across the holes at the bottom of your flower pots. It turns out, these holes are holy to your plants. It's the difference between life and death in most cases!

They allow for proper water drainage and avoid stagnant water buildup that can be very harmful to your flora friend. The holes also allow for roots to expand and grow beyond the confines of the pot!

Escalator Brush

While most of us may use escalator brushes as a handy on-the-go shoe cleaner, they actually have a far more important purpose.

Escalator brushes, also known as an escalator skirt (how cute!), are there to prevent anything from getting caught in the machine. The brushes keep any objects at risk of being trapped, like your coat or shoes, at a safe distance.

Dental Floss

We all know how important it is for our dental health to floss every day, and I'm sure we all do it! Right? Well, floss is more than just a protector against plaque. It comes in handy in the kitchen too!

Unscented floss makes for a perfectly precise cake slicer! Pull it tight, and you've got yourself an easy and clean way to cut up your baked goods with less mess than a regular knife.

Tea Bags

If you're a sufferer of smelly feet, then you'll know the overwhelming embarrassment of removing your shoes. There are many proposed tricks and tips to eliminate foot odor, but there's one in your kitchen right now!

Pop some unused tea bags in your stinky shoes overnight, and voila! By morning the stench will have disappeared as teabags act as effective odor absorbers. Just a warning, do not use them to make yourself a cup of tea afterward!

Wine Glass Stem

Ever wondered why wine glasses tower over all your other glassware with their long (incredibly fragile) stems? The stem is there to keep your heat-emitting hands as far away from the wine as possible.

By holding the stem, the wine in the glass remains unaffected by your body temperature. The stem also allows you to swirl the wine around and look like a wine aficionado!

Used Coffee Grounds

There is something magical about that first cup of coffee in the morning. Most of us can't kickstart the morning without our trusty cuppa-joe. The only problem is that coffee leaves behind a pile of used coffee grounds. Instead of tossing them in the bin, try tossing them into your garden!

Coffee grounds are great fertilizers! No, your plants aren't coffee addicts, but the acidic coffee grounds add a much-needed nitrogen boost to your plant's soil.

Doughnut Hole

What would the iconic doughnut be without a doughnut hole? Well... just a blob of dough. The doughnut hole has a really important job, apart from giving your tasty treat its defining shape.

The hole ensures that the dough cooks quickly and perfectly inside and out.

Bubble Bath

A good soak in the tub with candles and bubbles could cure many ills! Or at least make a bad day a lot better! Those beautiful bubbles do more than keep you clean and leave you feeling pampered.

A bubble bath keeps your water warm! How? Bubbles are great heat insulators and act as a makeshift lid to trap the heat in the bath.

Bread Tags

Whether your local bakery uses plastic tags or twist ties, take note of them! The tag or twist, depending on what color it is, tells you how fresh the loaf is!

It's a fool-proof way to get a fresh slice of bread every time!

Sound Bowl

If you have a few friends over and you want to play some music, head to your kitchen and grab a bowl! Why? It will transform your phone into a makeshift speaker system to get any party going!

Besides holding your food, a bowl is a perfect shape for soundwaves to bounce off of and reverberate around the room!

Backpack Buckle

Any adventurer will know the joy of putting a few things in a backpack and heading out to explore the world. Not only is it on your back, but your bag really has your back as well!

In case of an emergency, the buckle on the chest strap can be used as a whistle to send a distress signal!

Oven Drawer

Ever wondered what that compartment is at the bottom of your oven? It has a double function!

It's both a handy storage compartment for your pots and pans as well as a nifty dish warmer.

Muffin Pan

You may be delighted to know that you do a lot more with a muffin tin than just bake muffins!

All you need to do is flip it upside down, and boom! You have the perfect taco shell baker! Get ready for tacos at breakfast, lunch, and dinner!

Mouthwash

Next time you take a swig of mouthwash, try leaving some for your hair as well!

It may sound crazy, but mouthwash is a curious cure for dandruff. If you feel hesitant, just know that mouthwash has been used to destroy dandruff since the 1950s!

Chair Holes

I think we all remember those good old sturdy plastic chairs from school. They almost seemed indestructible! Ever wondered why there are always large holes cut out the back?

It's for ventilation. The holes allow for cool air to pass through and keep your back from getting too sweaty. It also helps to stack the chairs on top of one another.

Aluminium Foil

What is more frustrating than trying to slice vegetables with a dull knife? Not many things. But no need to rush to the store to buy a new knife if your old one isn't doing its job anymore.

Just reach for the aluminium foil in the cupboard and use it to sharpen your knife! You'll be back to chopping like a pro in no time.

Shoe Loop

The little fabric loop at the back of your boots is not just a label, it's there to help you out!

When you're trying to put your boots on, pull on the loop to make your shoe situation as smooth as possible. Now those boots really are made for walking!

Cotton Pad

There are two sides to every story, and there are two sides to every cotton pad!

If you look closely, you'll notice that each side has a different texture. One side is smoother and for more sensitive parts of your face (like your eyes), while the rougher side is there to help you successfully remove your harsher makeup on less-sensitive skin (like your forehead).

Egg Shells

When you've finished your eggy breakfast, save the shells! Ground-up eggshells can up your garden game and impress your neighbors.

Eggshells contain a lot of calcium, which helps plants buff up their cell walls.

The Screwdriver Shape

Even if you don't use tools very much, you're probably familiar with the hexagonal shape of the screwdrivers in your collection (or your dad's). As it turns out, this shape is for a specific reason – it's so you can use them with wrenches.

Sometimes you need a little more force to loosen those hard-to-reach screws or hardware that is stuck. Wrenches are made with a hexagonal shape for maximum grip. This is also why the handles of most screwdrivers are a certain size in diameter. Makes it a lot easier to work in tight places or at complicated angles.

The Number 57 on a Heinz Bottle

You've probably had some trouble getting the tomato goodness out of the bottle while you're trying to cover your French fries or add something to a burger. It turns out the designers of the most popular brand have come up with a possible solution.

The embossed number 57 on the bottle has been called a soft spot by the company's spokesperson. Apply a firm tap on the number, where the bottle begins to narrow, and the ketchup will flow a little easier. You don't need to abuse that poor bottle, just a little tap will do.

Sidewalk Bumps

Also known as tactile paver markers, those bumps on the sidewalk just before the road actually serve a very important purpose.

They're there so that a visually-impaired person who is walking with a cane or a guide dog can tell that they are close to the road. The sudden and slightly uncomfortable change in the ground alerts them that they need to be careful where they step.

The Shape of Toblerones

We've all enjoyed a Toblerone a time or two. Maybe it's even one of your favorite snacks! Ever wondered why they're shaped that way? An urban legend tells us that they're in that shape as a shout-out to the Swiss Alps since the candy originally came from Switzerland.

However, they're designed so that you can easily press on them with your thumb and break them apart into separate chunks. That way, you can easily share them with all your friends, or try to slow yourself down.

The Black Border on Windows

Maybe you've seen this sort of thing in business or in vehicles. It's actually called a frit, and it uses baked-in ceramic paint. There are several uses for this bubbly pattern. The first is that it prevents sun rays from damaging the window sealant. After that, it also creates a more abrasive surface to create more adhesion with the seal itself.

The dots themselves not only have an aesthetic function (a gradual introduction), but they also help reduce stress points by letting the glass heat up gradually – the black warms up faster than the rest of the glass.

Grooves in the Bottom of Cups

If you have a lot of ceramic mugs or similar cups, then you've probably seen that some of them have little grooves in the bottom. Maybe you've figured it out, but those grooves are to let water escape while they're getting cleaned in the dishwasher.

Usually, water collects in the indentations at the bottom of cups, only to spill all over you while you put them back in the cupboard. It's not something that every single brand has started doing (we bet that it can make some cups a little more breakable), but it's still handy when we see it.

Childproof Prescription Bottles

You're undoubtedly aware of the childproof caps that virtually all pill bottles come equipped with. They're really useful to have around, especially if you have little ones that like to get everywhere. However, if you don't have to worry about that sort of thing, you can adjust the caps to be easier to open – just turn them upside down!

They're no longer childproof at that point, but they're far easier to get open right after waking up, in the middle of the night, or if you have something like arthritis, which makes struggling with locked caps a big pain.

The Gas Pump Latch

Tired of standing and waiting while your gas pumps into your car? Don't want to keep your hand squeezing the trigger when you could be grabbing a snack or cleaning the windshield? There's almost always a small latch on the handle that you can use to lock the gas into a flow state.

Don't worry about overfilling – they're designed to shut off once your gas tank reaches full. Now you can get away from the vapid gas station entertainment, which might be the only thing more dangerous to brain cells than gasoline fumes.

The Extra Oven Knob

Ovens are super handy in everyday life, but they're actually slightly finicky. How many times have you had an oven that gets twenty-five or fifty degrees too hot, or it doesn't get hot enough? We bet everybody has at least one experience like that.

Newer ovens are better, but old ones still need to be checked. Some ovens feature an extra oven knob that lets you calibrate. Set it to 300 and test the interior with a thermometer. If it needs to be adjusted, pull the knob off and use the screws to loosen or tighten the knob, so it's more accurate.

The Ridges in a Toothpick

Toothpicks might not be as ubiquitous as they once were now that we have fancy toothbrushes and we all know how important flossing is, but they still get some use.

If you happen to be in a steakhouse and notice that the toothpicks have some ridges at the back end, this is why – you break the back end off and use the little piece of wood as a prop for your toothpick, so it doesn't touch anything else. That way, the thing that goes in your mouth stays a little cleaner.

The Tabs on Aluminium Foil Boxes

Most people have some aluminium foil in their kitchens somewhere, and even if they don't get a lot of use, they're one of those things that a lot of people just like to have around. If you have to use this handy tool often, you might be interested to know that there are tabs on either side of the box to lock the roll in place.

That way, you can tear off the right length with far more ease. You'll have to put a little more muscle into pulling the foil out, but you can manage that, right?

The Legs on Keyboards

You're probably confident that you know what the little legs on the backs of keyboards are for. They're for ergonomics, right? Easy. Well, surprise surprise, that's not what they're for at all. In fact, tilting the keyboard up is a little worse for ergonomics than leaving the keyboard flat.

We didn't know that one either. It turns out that the legs are for the eyes, not the hands. They were first added so people could see which keys they were hitting. Likely this was back before keyboards were commonplace, so people weren't as used to them.

Double-Container Greek Yogurt

Greek yogurt has become more and more popular in recent years – it's healthy and tasty, and there are a variety of toppings that you can customize it with. There are even some containers that have those yummy toppings right there for easy addition. It turns out that the double containers are built in a specific way.

They're designed so that you can fold the container up and dump the toppings straight into the yogurt with ease. It speeds up your snack, reduces the mess, and it's totally optional, so you can add as little or as much as you want.

The Flap on Toilet Seat Covers

Trying to stay clean while using public bathrooms is a common worry, but that's why we have toilet seat covers. Most disposal seat covers have a flap of paper that hangs down into the water so that when you flush, it gets sucked away with the rest of the refuse. If you've been putting the flap in the back, you've been doing it wrong.

The flap is supposed to go in the front, preventing the cover from being dragged down while you're doing your dirty work. The flap still hangs in the water, so it will still get sucked away.

Applesauce and Yogurt Lids

If you frequently pack a lunch (something we encourage – it's much healthier) and you have a little cup of applesauce or a pot of yogurt, you don't need to worry about including a spoon in your bag. The tin lids for these foods, and probably some others, can easily become a handy spoon with a few folds and twists.

You were going to throw it out anyway – why not give it an extra use and reduce the number of plastic spoons you throw away or the number of metal spoons you have to wash?

The Positioning of Exit Signs

You might not pay attention to them if you're on your regular commute, but the positioning of exit signs on highways and interstates becomes quite important if you're going somewhere new. If you're trying to get a handle on the ins and outs of a new city, take a look at where the signs are positioned as you're looking for your exit.

They'll tell you that the exits are on the right or left, which can keep you from missing your turn and getting lost in Boise or something like that.

Dual Zippers on Backpacks and Luggage

You might wonder why every backpack or piece of luggage has to have two zippers on the main compartment, and not just one. Well, it turns out there is a pretty important reason for having a pair of zipper pulls, and it's not just convenience.

Zipper pulls have holes in them that are made for padlocks and other safety pieces so that your personal items stay that way while you're on long trips. There are plenty of pieces of luggage that make it clear this is why there are two zipper pulls since they fit together in a snug way.

The Number in the Corner of Heinz Packets

This was a mystery that went around for some time on the Internet, but we finally have an answer, straight from the source. If you looked at the upper corner of Heinz packets (ketchup, mustard, mayonnaise, etc), you likely saw a number printed there, right where you would tear it open. What was it for?

Well, we'd like to tell you something fun, but the number was just placed there so that if you had an issue with the product, you could say which production line it was from. It was just quality control, that's all.

Mesh Bags for Oranges

If you're like billions of people around the world, you eat oranges. They're really good for you, they taste great, and they don't bruise. Most of the time, oranges come in little mesh bags that will go straight into the trash once you've eaten the last bit of citrus.

Reduce a little bit of waste and add something useful to your kitchen by balling the mesh bag up and tying it together with some string or a ribbon. Now you have something that can help you get dried-on food off your pots after dinner.

Reused Tissue Boxes

Maybe you're one of those people that is always blowing his or her nose. Maybe you only need to use a tissue box once a month to wipe up a spill. Well, one way or another, you'll have an empty one eventually, but you don't have to throw it out once it's empty.

Keep it around and fill it with those extra plastic bags that you have lying around. You might need those a lot more often than tissues, and now you have an easy way to organize them.
