We're so accustomed to the objects we interact with on a daily basis that we don't usually stop to question why they have some of the features that they do. We just take it for granted that coins have ridges on the sides of them and jeans have little metal pieces near the pockets.
What do those things even do? What's the point of them? Keep reading to learn more about the truth behind these hidden features.
The Margins On Lined Paper
Have you ever wondered why pieces of paper have margins? Why don't we just use the whole piece of paper?
Well, it's because back in the day, rats would often chew on the edges of papers. People would leave the margins blank so their words would stay intact.
The Holes In Lollipop Sticks
All lollipop sticks have little holes near the top of them where the candy sits. That's so the molten sugar has something to grab onto.
It keeps the candy from falling right off.
Half-Belts On Coats
During the First World War, soldiers' coats used to double as blankets.
That meant that they had a bunch of extra material, and the half-belts would hold all of that material up and out of the way.
Those Little Holes In Padlocks
Those little holes in padlocks aren't quick release or lock-picking systems.
They allow water to drain out of the lock, and they allow you to put oil into the lock if you want to loosen it up.
Cedar is a great material to use in any kind of clothes storage. It helps repel moths and other bugs.
That's why a lot of wooden hangers are made out of cedar.
Little Holes In Airplane Windows
If you've ever been on a plane (or, more specifically, in a window seat on a plane), you might have noticed some tiny holes in the glass.
Those holes exist to depressurize the cabin.
The Embossed 57
All glass Heinz ketchup bottles have a little 57 embossed on the sides of them.
Apparently if you tap on that 57, the ketchup will flow out of the bottle easier.
The Bumps On Your Keyboard
The little bumps on the F and J keys on your keyboard exist to help you find your "home row."
It helps you type without looking down at the keyboard the whole time.
Buttons On The Left Of Women's Shirts
Men's shirts button on the right, but women's shirts always button on the left.
That's because left-hand buttons used to be a sign of wealth because they implied that you had a chambermaid to dress you.
The Drawer Under Your Oven
That drawer under your oven isn't really supposed to be used for storage. It's supposed to be a warming drawer to keep your food hot.
I'm still going to put baking sheets in it though.
The Holes In Pen Caps
Holes in pen caps were put there to stop people from choking on pen caps. That way if you accidentally swallow one, your airway won't be completely blocked.
It's an essential safety feature.
Rivets In Denim
Rivets (those metal bits) exist to hold thick denim fabric together, especially in places where jeans are likely to fall apart.
They aren't just there for decoration. They actually serve a purpose.
Back in the day, the value of a coin was determined by its weight. Some people tried to cheat the system by shaving off the edge of a coin to make it lighter.
The ridges were added to make it obvious when a coin had been filed down.
Brass as a material actually has a lot of antimicrobial properties. That means that brass doorknobs are basically self-cleaning.
That's a really great feature to have in an item that gets touched so much.
The Arrow On The Gas Gauge
If you're unsure which side of your car your gas tank is on, you can always look at your gas gauge.
The arrow next to the picture of the gas pump points to the side with the gas tank.
Pom-Poms On Winter Hats
Back in the day, pom-poms on hats were more than just decoration. They protected sailors' heads when they were below deck during a storm.
Those ship ceilings were pretty low.
Small Pocket In Front
Do you know what the tiny pocket in the front of jeans is for?
It's not for lighters—it was originally created for pocket watches. Now you know its purpose, but these days, it's pretty useless.
A Hack With Onesies
If you ever paid attention to onesies, you'd see that the neck has a strange construction.
That's because it allows you to pull it down off the baby if the diaper load is too nasty.
