There are many different little things in our life, the true purpose of which we do not even think of. But they were invented for our convenience and comfort.
We are at the editorial office of Our site decided to tell you about the true purpose of the small details of 7 items that we use literally every day. Let `s start?
Rubber lining under the soda lid
Purpose: keeps gas in the drink
Horizontal stripes on the keyboard
Purpose: are a hint for people who blindly dial
Small hole at the bottom of the padlock
Purpose: protects the lock from rust, removing moisture from it
Small pocket on jeans
Purpose: it was originally designed for a regular lighter, but then it became just a tribute to tradition and lost its original function
A tiny hole in an airplane window
Purpose: conducts air between the cockpit and the space between the two layers of glass in the window, which normalizes the gigantic difference in pressure outside and inside the cabin. If not for this little hole, all the windows in the portholes would have simply cracked.
Holes on the side of the sneaker
Purpose: if you use these small holes when tying the laces, the ends of the laces will not interfere with walking. Also, with the help of these holes you can "narrow" the shoes
