These “Truths” You Believed As A Kid Were All Lies

Do you remember listening to your teacher during a lesson a kid and taking everything they said as fact? Then, later in life, you learned that daddy long legs aren’t really spiders and that Twinkies don’t really last forever. The truth is that at a young age, teachers, parents, friends, and role models tell a lot of lies. These are the biggest “truths” you spent your whole life believing that were actually lies.

Coffee Dehydrates You

There’s a commonly-held misconception that your morning cup of coffee will dehydrate you. While it is true that drinking coffee will make you have to use the bathroom more frequently, there is no evidence to suggest that this will dehydrate you.

Dr. Daniel Vigil, an associate professor at UCLA, says, “When you drink a cup of coffee or you drink a glass of iced tea, you are necessarily taking in a volume of fluid along with that dose of [caffeine].”

Daddy Long Legs Are Spiders

Because daddy long legs are arachnids, we tend to believe that means they are also spiders. The fact is there are many different kinds of arachnids, and daddy long legs belong to the group known as harvestmen.

Once you know the truth, you can start to learn just how different harvestmen are from spiders. First off, daddy long legs have two eyes, spiders have eight. Daddy long legs also have a fused head, abdomen, and thorax, whereas spiders have a distinct separation of their body cavities.

Tilting Your Head Back Will Stop A Bloody Nose

If you’ve ever gotten a bloody nose, you’ve probably heard at least one person tell you to tilt your head back to help stop it. If you want to swallow your own blood that’s definitely an option. If you want to stop the bloody nose, though, you should actually do the opposite.

When that pesky nosebleed happens, sit up straight and lean your head forward slightly. And don’t forget to apply pressure. As annoying as they are, most bloody noses clear up in 10 to 20 minutes.

Cracking Your Knuckles Will Cause Joint Problems

According to experts, there is no correlation between cracking your knuckles and future joint problems. The sound of knuckles cracking can be bothersome, which is most likely how this lie took off.

The sound of cracking knuckles, however, isn’t cracking at all. It’s actually the sound of gas bubbles popping as you increase the space between your joints. If you crack too hard, you may suffer an injury to your tendons, but this rare.

The Winter Makes You More Likely To Catch A Cold

While there is some truth to the statement that you are more likely to get sick during colder months, it’s more coincidence than anything else.

As Shannon Fecher of UnityPoint Health explains, “Can you get sick from being cold? Yes, but not in terms of a cold or the flu. This comes from frostbite and/or even hypothermia. If you get frostbite or hypothermia, this can weaken the immune system, which leaves you more at-risk for getting illnesses, such as the common cold and/or the flu.”

Twinkies Last Forever

While movies like Zombieland have spread the myth that Twinkies will last forever, the truth is harder to swallow. Thanks to the preservative sorbic acid, the sponge cake with a cream filling stays good for about 25 days.

Once those days are up, the snack food will begin to lose its texture and flavor. As proof that Twinkies don’t last forever, one school in Maine has held onto one for 40 years. In that time it has turned gray and hard.

We Only Use Ten Percent Of Our Brain

Although the myth that humans only use ten percent of their brains has been thoroughly disproved, it’s still prevalent in society. Movies like Lucy and Limitless have even centered their plots about what happens when the “other 90 percent” is unlocked.

In an interview with Scientific American neurologist Barry Gordon explained that at any given moment, a majority of the brain is always active. It’s time to put the ten percent myth to bed.

Gum Stays In Your Gut For Seven Years

Chewing gum is not meant to be digested, and to dissuade kids from swallowing it, parents like to say that it will stay in your stomach for seven years. Just because gum isn’t made to be digested, however, doesn’t mean it will refuse to flush through your body.

In general, it will only take gum a few days to pass through your body. That doesn’t mean you should start swallowing gum when you’re done with it, though!

Vitamin C Is A Miracle Cure

Back in the 1960s, Nobel Prize-winning chemist Linus Pauling (pictured) came up with the idea of “megadosing” on vitamin C. He claimed this would help prevent people from getting sick with common ailments.

Since then, the idea of “megadosing” has been proven wrong although it is still used as a marketing trick for supplement brands. It is true, of course, that vitamin C will help reduce how long a cold lasts, but it will not stop you from getting sick.

Bats Are Blind

GREG WOOD/AFP via Getty Images

Because we’re taught about how bats use echolocation in school, we tend to believe that means they are blind. According to National Geographic, not only are bats able to see just fine, some species can even see three times better than humans!

Speaking of echolocation – not all bats rely on it to find food. Fruit bats, for example, don’t use echolocation at all. Fun fact, another name for fruit bats is “megabats.”

Salt Boils Water Faster

Salt might make food taste better, but it does not make water boil faster. Adding salt to your pot of H20 will actually make it boil more slowly. Oddly enough, adding salt will make your pasta cook faster.

Because adding salt to water will increase the temperature needed to make it boil, the pasta you drop in cooks at a higher temperature. That higher temperature results in noticeably faster cooking time.

You Need To Wait 30 Minutes To Swim After Eating

You do not have to wait 30 minutes after eating to go swimming. This popular falsity was spread through a past belief that blood would be sent to your gut to aid in digestion after eating. With less blood in your legs and arms, you would fatigue more easily.

In 1908, the Boy Scout handbook Scouting for Boys further perpetuated the myth, writing, “You may drown—and it will be your own fault.”

Carrots Make You See Better

For years carrots have been branded as having a superpower — the ability to improve a person’s eyesight. The false truth comes from the fact that carrots are high in vitamin A, a nutrient that helps your eyes see clearer in low light conditions.

A lack of vitamin A in a body may also lead to blindness, so keep eating carrots. Just don’t expect to suddenly be able to stop wearing glasses in the process.

Elephants Are Terrified Of Mice

If you grew up watching the movie Dumbo, you may believe that elephants are terrified of mice. While the movie may have fooled audiences into believing this to be true, the facts don’t add up.

What is true is that elephants have poor eyesight, so they could be startled by a fast-moving mouse or rat. That does not mean they will stampede away in utter fear of an animal that is a fraction of their size.

Goldfish Have A Three-Second Memory

There have been several experiments produced that prove goldfish have a memory that lasts for more than three seconds. Jamie Hyneman of Mythbusters fame even trained his fish to run an obstacle course.

More famously, a study at the University of Plymouth trained goldfish to use a lever to earn food as a reward. The lever was only activated for one hour of the day, so not only did the fish have to remember how it worked, they had to remember at what time it worked!

Chameleons Camouflage By Changing Colors

The ability of a chameleon to change color is not actually a self-defense mechanism. The reptiles might be able to blend in with their surroundings sometimes, but more often than not, they are using their color-changing ability to communicate with one another.

Every chameleon has four layers of skin. Three of those layers have various colors and preset patterns. By changing colors in front of each other, they can help better display their emotions and how they’re reacting to their environment

Melatonin Is A Sedative

All across the world, people struggle with sleep. Many turn to melatonin, which has been marketed as an all-natural sleeping aid. Taken in pill form, the naturally-produced hormone is commonly confused as a sedative.

Taking melatonin won’t make you fall asleep, but it will assist in helping you get a better night’s rest. Just be warned, by taking the supplement, you can develop a resilience to melatonin and actually decrease your ability to stay asleep.

Dogs Don’t Sweat

Dogs do sweat, they just don’t sweat from where you might expect them to. The sweat glands for dogs are located on the paws. When they do sweat, the moisture released helps them grip the ground easier.

To regulate temperature a dog will pant, which is why it’s commonly believed that dogs don’t sweat. Panting helps to lower body temperature by allowing water to evaporate from a canine’s nasal passages and tongue.

Water Is Stored In A Camel’s Hump

We’re not sure what started the rumor that camels store water in their humps, but the truth is they actually use their humps to store fat. By loading up on fat, up to 80 pounds of it at a time, camels can survive three weeks without “refueling.”

Camels also have oval-shaped red blood cells, and highly efficient intestines and kidneys that allow them to stay hydrated without a nearby water source.

Alcohol Warms You Up

When you drink, you might suddenly feel warmer, but that doesn’t mean you are. As much as you might want to reach for an old fashioned in the dead of winter, choosing hot chocolate instead might be the better choice.

The facts on this one are clear; drinking alcohol actually lowers your body temperature. This causes your blood vessels to constrict and rise to the surface, making your skin feel warmer.

The Sun Creates The Seasons

Believing that the sun, and the Earth’s proximity to it, is the reason for the seasons seems logical but isn’t the whole truth. The closer we get to the sun, the warmer the weather gets, meaning if the sun controlled the seasons, we probably wouldn’t have four distinct variations.

The reason for the four seasons is that the Earth rotates on a tilted axis. Scientists at NASA believe this tilt was created by another space-bound object crashing into the earth.

Ancient Statues In Greece Were Always Colorless

Today, almost every statue we have recovered from ancient Greek sites all lack one thing — color. This has led many to falsely believe that grey statues were all that was ever built back then.

If we could take a time machine and travel back to ancient Greece, we’d find the statues were actually decorated with vibrant colors that wore away over time. Artists of the era practiced polychromy, which means exactly that.

Snakes Can Unhinge Their Jaws

Snakes cannot unhinge their jaws to swallow large prey. What they can do is stretch their jaws to open their mouths really wide. This is because their upper and lower jawbones are not fused together.

Instead, these bones are connected by stretchy ligaments that allow the snake to open their mouths extremely wide. To human eyes, it looks like they are unhinging their jaws, but we promise you they are not.

Bulls Hate The Color Red

If anyone has ever told you that bulls hate the color red, they were wrong. Bulls are colorblind, so they can’t actually see the color red. When you watch a bull going after a matador, they are actually responding to the person’s movement, not the color of the cape.

The bull is upset by the movement and trying to make it stop. The fact that the cape is red has just become a recognizable detail for audiences to react to.

Without Oxygen, Our Blood Is Blue

Even though our veins can appear blue at times, the blood flowing through them is always red. Depending on how oxygenated our blood is, it may appear to be a lighter or darker red, but it is never blue.

Our veins appear blue for another reason entirely. When light hits our skin, it reflects back at a certain wavelength, and that wavelength is responsible for the blue hue we can’t help but see.

Black Holes Have Endless Gravity

One of the biggest misconceptions about black holes is that they have an endless gravitational pull. If that were true, then everything in existence would slowly be getting sucked into one right now.

As with any large object in space, if you get close enough you will get pulled in by its gravitational pull. If you stay a safe distance away, however, you will be just fine. Aside from being pulled into a state of “awe,” of course.

Lightning Doesn’t Strike The Same Place Twice

Lightning isn’t picky. Let’s get that out of way right now. Lightning has no choice about where its strikes, it’s a naturally occurring phenomenon. Did you know that the Empire State Building in New York, for example, is struck 23 times on average per year?

So where did the saying come from? Most likely it was originated on the pages of The Melbourne Daily Newspaper in 1851 and spread from there.

Your Tongue Has “Taste Sectors”

In school, we were taught all about taste, and how putting food on different parts of the tongue would create a different tasting experience. Our teachers said that there was a tongue map with “taste sectors” set to identify different traits — salty, sweet, sour, and bitter.

This idea of the tongue map was first created by a German scientist in 1901 and has since been disproved. Taste buds all over your tongue are able to identify all four flavor sectors, five if you count umami.

The Great Wall Of China Is The Only Man-Made Structure Visible From Space

If you ever found yourself in a space station orbiting the Earth and looking down, would you be able to see the Great Wall of China? According to Yang Liwei, a Chinese astronaut who tried, he could not.

He could see other man-made structures though. As cities light up at night, they become visible to astronauts in space. So, even if Yang Liwei could see the Great Wall from space, it would not be the only structure visible.

Bananas Grow On Trees

Because of how tall banana plants are, we don’t hold it against you if you thought that the sweet berry grew on trees. The plant they come from reaches heights of 25 feet tall and is considered the world’s largest perennial herb.

Also, a common misconception about bananas is that they are fruits. As you just saw, we referred to them as berries, which they are because they don’t produce mature seeds.

Those Pot Handle Holes Can Be Very Helpful

While a lot of us may use those holes on pan and pot handles to hang them up when not in use, there’s actually a cleverly hidden feature not many of us know about.

Let’s be real here: if you have time to cook and if you find it to be rather tedious while doing so – before you know it, everything gets messy and you wonder why you didn’t just order takeout in the first place – there’s a little hidden feature that may just make things a lot easier and cleaner. That little hole on the handle can be used to keep your utensils from getting dirty while you are cooking. Who knew?

Airplane Window Holes Are Real

If you’re an avid window seat occupier on airplanes, then you’re probably familiar with those little holes you see on the windows. Have no fear! They are there for two good reasons.

The first reason is to compensate for air pressure, so when the plane reaches cruising altitude, there is a huge pressure difference between the inside and outside of the plane – as you can tell by your ears popping. The hole regulates some of that difference so the outer window doesn’t have to do all the work. The other reason is that it prevents the windows from fogging up.

Fast-Food Fans Will Love This Next Trick

Although using the tiny paper condiment cups might seem a little counter-intuitive when eating at a fast-food restaurant, they actually serve a bigger purpose, literally. You’ll notice that the cups have a specific fold in them that can easily be expanded to turn that small cup into a rather large saucer.

Now, you can use more of your favorite condiments while simultaneously having more room to dip your food. It’s a trick of the trade. Think smarter, not harder! We just ask that you don’t use this little trick while you are behind the wheel of a moving vehicle! Safety first, friends.

But What About That Pasta Spoon Hole?

Let’s face it: some, if not all, of us have utensils we are not quite sure about yet we just go along with it because our parents have shown us their functionality all our lives. So what about that pasta spoon? What’s up with that hole in the middle?

Slotted spoons have a neat feature that allows you to strain the pasta and let the water drain out. On some spoons, the hole is just about the size of a single portion of spaghetti. So if you ever wanted to insert spaghetti into a pot without splashing boiling water everywhere, there you go!

Ever wonder what that little arrow on your gas gauge means? Well, we’re here to tell you that little symbol might be one of the more important features of your vehicle. It tells you which side of the car your gas gauge is on!

No longer will you have to rack your brain trying to remember what side to pull up on when you’re at the gas station. All you have to do is look at the little symbol sitting next to the picture of a gas tank. Do you know what that means? No more playing chicken with other cars while you decide which pump is correct!

Ever Have an Eraser With a Blue Side?

As a kid, and sometimes even today, erasers were essential for anyone in school. While it has been known to erase pencil marks, that blue side has a purpose as well!

Turns out, that blue side of the eraser is meant to erase pen ink but it actually only works on very strong and thick paper. The blue side of the eraser is harder and more abrasive than the soft, pink side. It also takes a lot more paper off when you use it, hence all the times you’ve ripped through your paper while using it.

After reading this, you’ll swear you have been eating Tic Tacs wrong since forever! Mark our words! We were quite shocked too.

Maybe you have noticed that little indentation on the lid of the Tic Tac package. While many, if not all, of us thought it was there to somehow tightly seal the container, we have been wrong for decades! That little indentation is actually there to serve as a dispenser that gives you one Tic Tac at a time! But wait! Who actually eats one at a time though?

Ever go to pick up your Chinese takeout only to be greeted with a funny look when you ask for paper plates? Well, there’s a good reason for that, and it’s not because the cashier thinks you could just use your normal plates. Much like the fast-food condiment cups, Chinese takeout containers are folded in such a way that you are able to unfold them and utilize them as dinner plates!

No need to use valuable resources when we all know you’re going to finish that container of chicken lo mein anyway. Take it in stride, people, and use what you are given to its full extent!

What The Black Diamond On A Measuring Tape Is For

It might be something you’ve never given much thought to before, but those little black diamonds (sometimes triangles) on a tape measure are there for more than decoration. They’re known as “black truss” markings. They begin at 19.2 inches and go all the way to 96 inches (eight feet).

Their purpse? For every eight-foot section of wall, there should be six studs placed 16 inches apart. The black markings show where the studs should be. The first mark indicates where the center of the first stud in a wall is located. Knowing where the studs are can be very useful when hanging items on the wall!

Converse All-Stars are probably the most iconic sneaker in the world, but they come laced with some mysteries. See what I did there?

Those little holes on the side of the shoe have been known to be air holes for your feet, but there’s actually a better explanation. Being that Converse were originally basketball sneakers, the holes allowed some alternate lacing technique that stopped players from tripping n their laces on the court. So while there may not be a reason for them to be there nowadays, those little holes remain an iconic feature on the shoe.

If you’ve ever had to open a prescription pill bottle, you know the pain that it can be at times trying to get through the child lock. Luckily, not all pharmacists intended people to suffer every time you need your medication, especially if there aren’t children around. If you simply turn the cap upside down, it will fit snugly onto the pill bottle.

Even if it’s knocked over, the pills won’t spill out, but it allows for easy access to your medication (as long as children aren’t around). Good trick, especially if you aren’t feeling well and don’t want to deal with lining up the tiny arrows on the bottle.

Aside from the actual lock, the extra little hole is very important. Weirdly enough, it acts as a drain for any padlock you might be using outdoors. Meaning, your lock won’t rust, freeze, and then break on you. It will be in tip-top shape for all of the elements it will face while doing its job outside.

It also is used as a way to oil your lock. No need to hurt your ears with horrible squeaking noises! Long story short, that extra little hole is there to make sure your padlock is always in working condition.

You know those tiny little pockets on your jeans that don’t really seem to be good for, well, anything? It turns out that these little pockets actually have a purpose after all. In the 1800s, nearly everyone had a pocket watch and that little pocket is where they kept them!

Nowadays we tend to use the bigger pockets to stash our wallet, keys, and whatnot so the little pocket is sort of just there for show. However, if pocket watches ever do become trendy, we know where we’ll keep them!

You’ve Been Using Bobby Pins All Wrong

We all have used bobby pins for various reasons, whether it be for styling hair, getting yourself out of a tricky situation or for other discovered needs along the way. Bobby pins are just those things lying around the house that are either super useful for some or overlooked by many.

But have you ever wondered why bobby pins have one side shaped like a zigzag? Since they are famously known for styling hair, the grooved side is the bottom of the pin and it should face toward the scalp! The grooves help the hairpin hold the hair better. Helpful info!

If you’re like us, you’ve played around with those strange little wings that come out of the sides of Apple power cables. But what are they actually meant to do, besides helping those with ADD? Well, start by wrapping the thicker cable around the big power block, then wrap the thinner part of the cable around the wings.

Once you get there, secure everything with the little clamp on the very end. Who knew you could organize those cables without them becoming a huge jumbled up mess? Not us, that’s for sure. We stick our cables in our bags and they come out in about 60 different knots.

Pen Lids Keep the Pen From Drying Out, Right?

Since childhood, once our parents allowed us to use ink, it has been drilled in our heads that it is important to keep the lids on pens to keep them from drying out, and to keep a pressure balance that can prevent the pen from leaking. But turns out, the hole in the pen lid has a purpose, too.

The holes in pen lids are actually there to lower the risk of suffocation of small children. If a child was chewing on the cap and choked on it, the hole keeps their airway from closing up entirely, thus preventing suffocation. Raise your hand if you chew on pen lids all day at school!

What’s With The Produce Stickers?

We’ve all bought fruit before that has come with that pesky sticker you take to take off. But what are they really for, aside from boasting the occasional brand name and helping cashiers ring up your item?

Turns out that stickers on fruit mark the country and the producer. The numbers are usually 4 digits with the first number being 4, meaning that the fruit has been sprayed with pesticides. If there are 5 digits and the first is 9, the fruit has been grown organically. However, if there are 5 digits and the first is 8, the fruit has been genetically modified.

Ever Wonder About That Little Metal Bit at the End of a Tape Measure?

If you’re not particularly handy, this will probably blow your mind. The little metal bit at the end of a tape measure can be incredibly useful.

If it’s serrated, it’s really useful when putting up drywall. The edge lets you easily score softer surfaces. While the bit slightly often moves back and forth, it is actually compensation for the width of the metal hook and it pushes in if you are measuring an inner surface while pulling out if you’re measuring an outside surface. The bit stops the slight width to throw off the measurement while moving the exact width of the metal hook, usually 1/16th of an inch.

Dots On The Windshield Are Meant To Be There

Ever noticed that there is a black band running along the edge of windshields that is usually followed by a series of small dots? Well, this is known as the “frit” of a windshield which is baked-in ceramic paint that has a variety of functions. First and foremost, it protects the sealant from ultraviolet rays which keep the glass in place.

It also helps to conceal the dirt that builds on the edge of the glass. The dots, on the other hand, are used to transition from the black frit to the transparent glass, which also helps with temperature distribution.

The Hole In Rulers Actually Have A Purpose

This one made us roll our eyes because it is such an obvious explanation. The holes in rulers are so they can easily also be placed into three-ring binders when they’re not in use.

If only math were as simple as storing all the necessary tools. But, beggars can’t be choosers and here we are shaking our heads that we didn’t realize what those holes were used for during our childhood.

But What About Those Studs?

OK so we delved into the reason why we have those tiny pockets on our jeans but what about those studs?

Turns out, when jean king Levi Strauss crafted his first pair of jeans, it was a pretty common issue for the seams of the pants to tear due to the stress being put on them by the wearer – mostly workmen and coal miners. Those little studs, called rivets, exist to strengthen the jeans at the most conspicuous spots! So basically, rivets exist solely to make sure that our pants are durable and that they last a very long time.

Why Do Wine and Champagne Bottles Have Those Indentations at the Bottom?

So what is really up with wine and champagne bottles having those indentations at the bottom? While some of us probably thought they were for show or for some fancy decoration, there’s a better explanation.

The indentations are there to compensate for the pressure of the contents of the bottle when it goes through the corking process. The bottoms and sides of bottles are considered to be weak spots and the indentations help to evenly distribute the pressure inside. Champagne bottles have much deeper indentations since they are under much more pressure due to the carbonation.

Why Do Coins Have Rigid Edges?

We all love money yet never think to ask about why it looks the way it does. It pays for everything so just shut up and use it, right?

If you have ever wondered why coins have rigid edges, you might want to look back as far as the 16 century. At the time, people would cut off small amounts of precious metal from coins to sell while passing on the damaged coins at full value. To counter this action, a special process called reeding was introduced, consisting of carving a series of grooves on the edges of coins so that you’d know it was tampered with. Reeding remains a long-standing tradition.

We all have a bunch of random USB and cable cords lying around the house somewhere. Chances are, you have no idea what device each cord belongs to, but here is something you’ll be amazed to learn.

Those little cylinder-shaped lumps on the cords are called ferrite cores or chokes. They are essentially just chunks of magnetic iron oxide that are meant to suppress high-frequency electromagnetic interference. So if you’ve ever experienced interference when your cell phone gets too close to a speaker, ferrite cores are there to prevent that from happening to your other electronics.

Do you know that little disc under the lid of plastic water and soda bottles? They serve a special purpose as well. You might find that removing them doesn’t cause a problem.

Most trained typists know what those little bumps on the F and J keys are for on a keyboard, but for the rest of us, we’re a bit lost, while others really never noticed them to begin with.

Turns out, in 10-finger typing, the F and J keys are the home keys – the keys where your index fingers rest. Those little bumps on both keys let you find your way back to the home position without having to actually look down at the keyboard. While a lot of us probably don’t follow the rules of 10-finger typing, it’s still a fun tidbit of information, right?

You know when you buy new clothes and they come equipped with that trusty extra piece of fabric? To some, we just figured it was for fixing rips and tears, right? Wrong!

Actually, those extra pieces of fabric are included so that you can test the colorfastness of the fabric when it becomes laundry time. How clever! It has been advised to keep those fabric pieces when you’re changing laundry detergents or experimenting with a new stain remover. So instead of ruining your new clothes, you can simply test the fabric to see the end result before you wash.

Yes, folks – no more looking like a fool as your head bobs around to get the damn straw in your mouth. Amazing, huh?

If you’re like us, you used to pry those little plastic discs out of water bottles, soda bottles, beer bottles, and any other bottle that contained one. Really, what possible purpose could those little plastic discs actually serve aside from being turned into really weird ’90s bracelets?

Truth be told, those little discs keep everything in the bottles! The water, the carbonation, the whole enchilada. Without that ring, you’d have a flat soda in no time and it would be leaking through the top of the bottle was ever knocked over. Keep that in mind next time you’re feeling bracelet nostalgia.

If you’re an avid fan of getting a manicure, then you’re probably familiar with the act of cutting off your cuticles to get a perfect look, but you might want to stop after reading this!

The tiny area of skin known as the cuticle is actually there to protect your nails from infection. By removing the skin, your nail is exposed with a tiny wound, allowing bacteria and fungi to sneak in. So cutting your cuticles may be a part of getting a lovely manicure but it actually doesn’t benefit your nails in any way. Plus, it can be quite harmful.
