Our lives are full of objects that we take for granted, rarely sparing a thought about how they came to be or the way they function. However, as curiosity is the best cure for boredom, there are many among us who wonder about every little detail with childlike inquisitiveness. For those, we are solving ten mysteries about everyday things we encounter on a daily basis, but whose purpose we could never really put a finger on. Keep scrolling!
1. The loop on the back of shirts
There are three uses for the loop, although there is no proof about which use was the original intention of the designers. The most obvious use is hanging the shirt on a hook without having to use a coat hanger.
The loop can also be used to help one fasten a tie easier when there’s no one around to assist.
There used to be another use for the loop, and quite an interesting one at that. It used to be an American college tradition to use the little garment as a declaration of one’s relationship status. When a male student would start dating a girl exclusively, he would remove the loop from his shirt, while the girl would wear a scarf with the university’s logo to show she was taken.
2. The cylinder on your laptop’s power cable
The mysterious cylinder is called “ferrite bead” or “ferrite choke” and its role is to suppress high-frequency noise in electronic circuits. The dark matter you see below is ferrite, which is a type of magnet.
3. The tiny hole at the bottom of plane windows
Airplane windows are made out of two pieces of plastic glass. Without the tiny hole in the window, the inner piece of glass would shatter due to the difference in pressure in the cabin and outside.
The tiny hole allows air to move from the cabin to the other pane, thus balancing out the pressure and preventing damage.
Watch the video below for the rest of the fascinating stories about things whose purpose we had no idea about and how they originated.
