There are so many things we just don't know about the world but that completely make sense. We go through the motions so much that we forget to pay attention to the details or choose not to learn the facts.
Get ready, because these are things that you never realized but make perfect sense.
The Secret To The Bubbles
Taking a bubble bath isn't only about self-care. Did you know that the bubbles act as a heat insulator? That means the water gets cooler much faster if you don't use bubbles.
This tactic usually only works with modern acrylic tubs.
The Hole In The Lid
If you love coffee, chances are you've probably noticed the tiny hole in the lid.
It's very scientific why it's there, but simply put, that hole allows air into the cup when you're sipping, so the flow of coffee is more regular.
Is There A Purpose?
Perhaps you've purchased a dress shirt or two over the years that have a small, awkwardly placed pocket on the side and toward the back. If this pocket seems useless, that's because it is!
While the original purpose of the pocket is essentially irrelevant, garment manufacturers are still adding these to shirts. That's because the pocket allows them to classify the garment a certain way that lessens tariff fees.
The Black Film On The Microwave Door
Microwaves are really helpful when you're hungry and need something quick.
They also have a black film cover on the door, which is an enclosure used to block electromagnetic fields.
More Uses For Sunglasses
One might think sunglasses are just for blocking the sun, but there's more.
Darker glasses were invented by Arctic peoples who needed to protect their eyes from light reflected off the snow.
The Holes In Chocolate Boxes
Manufacturers made it easy to get your chocolate fix, but not everyone utilizes the trick.
The holes are there for you to press and easily get the prize from the package.
The Donut Shape
In the past, it was difficult to get the middle and edges of a donut evenly baked.
Today, they can make them in any shape, but that wasn't always the case. That's why they came up with the hole shape to help with cooking.
The Dimples On Golf Balls
Initially, golf balls were smooth. After trial and error, players found that they played better with the distressed balls (cracks, old, scuffed, etc.).
Manufacturers picked up on this and created artificially aged dimples.
Stickers On Fruit
You've probably noticed that the majority of produce has stickers on it. If there are four digits and the first number is four, it was sprayed with pesticides.
Five digits starting with nine as the lead means it's organic.
The Stripes On Earphone Jacks
These stripes aren't for decoration or to boost aesthetics.
They indicate what type of headphones you have: one stripe means the sound comes in mono; two stripes means it's in stereo; and three stripes means it includes a microphone.
You've Been Had
Thanks to Hollywood, people think Africa is only sand or savannah.
Here's an image from Morocco, a beautiful sight to see. It's like this in many places in North Africa, but it's not what the public is used to seeing.
Nail Cuticles Aren't Meant To Be Cut
The hard layer of skin at the base of your nails is called the cuticle.
Many people cut them to keep their hands looking fresh, but that's not a good idea. They actually help protect your nails from infection!
"In Australia We Give Crocodile Feet As Treats"
Anything is fair game in Australia at this point.
From the dangerous wild animals to feeding your dog croc feet, this is really a place you live freely without a care.
Why They're Called Eggplants
If you didn't know, before they're ripe, eggplants look like real eggs.
There had to be some reason why they earned the name they have. Going from this to being long and purple is crazy.
Never Distract A Service Dog
As cute as they are, one mustn't get a service dog distracted.
If they slip on their duties, their owner could fall into a diabetic coma or seizure because the dog failed to do its job thanks to you.
Potatoes Before The Sack
Prior to ending up in grocery stores inside of bags, potatoes live in a giant warehouse like this.
I don't know what you expected, but this isn't what I thought.
The Redder The Gills...
In Turkey, they flip the gills of fish inside out as a way of showing customers how fresh the catch might be.
If they are redder, it's a fresh catch. Pale gills mean they've sat for a while.
Apple Trees For Bonsai
You can use apple trees for the art of bonsai, but that doesn't mean the apple spirit goes away.
Even after all the trimming and shaping, it can still bear fruit as you see here.
Foodception
There's no way of telling if your meal had a meal before getting caught when it comes to mussels.
You might find something like a crab inside them one day.
It Gets Cold For Them Too
You wouldn't expect a sea creature to look like a man with a frozen beard in the snow, but here it is.
The cold climate in the water also gets too cold for sea life at times.
Pearls Inside
Much like the mussels, you can find a surprise in oysters as well.
No matter how you cook them up, you could still find a pearl inside at no extra cost.
Long Fire Hydrants
Who knew fire hydrants ran so deep underground?
It makes sense on paper, but it isn't something you'd imagine since what we see is such a small portion of it.
A Hidden Whistle
Most people have plenty of objects with this style of buckle, from backpacks to belts to luggage. While the primary purpose of these buckles is to indeed buckle up, many have an intriguing hidden feature.
If you have a buckle with the little nub that's seen on the right side here, try blowing into it, because it's likely a whistle. It's a low-tech piece of kit that could literally save a person's life.
Sprouting Strawberries
Did you know that strawberries have their seeds on the outside? At times, they can sprout on the exterior, which is called vivipary.
That process can also happen with fruits that have seeds inside, like tomatoes.
