1. The Hole in Your Pen Cap 🖊️
That small hole is not for design o…
It’s there to allow air pass through—so if a child mistakenly swallows it, they won’t suffocate immediately.
Yes… it can save a life.

You think it’s useless?
It was originally made for keeping pocket watches safely back in the day.
Now we just ignore it.

Look closely at your car dashboard…
That arrow shows you which side your fuel tank is on.
No more confusion at the filling station again!

4. The Hole in a Padlock 🔒
That tiny hole at the bottom?
It helps drain water and also allows you to oil the lock so it doesn’t get stuck.
Smart design!

5. The Lines on Your Toothpaste Tube 🪥😳
Some people say the colors mean chemical levels…
But truth is—those lines are just for machines to know where to cut and seal the tube during production.
Nothing spiritual about it 😅

6. The Bumps on Your Keyboard (F & J Keys) ⌨️
Ever noticed them?
They help your fingers position correctly while typing—so you don’t need to look at the keyboard.

7. The Hole in Your Phone Charger Plug 🔌
