Awesome Things Whose Purpose We Could Never Have Guessed!!!!

The hanging loop on the back of your shirt

There are three plausible explanations for this. The first one is the most obvious- it’s for hanging up your shirt. The second explanation comes down to us from the era of removable shirt collars and handkerchiefs: it may have been intended to somehow help fasten a tie. The third idea is the most romantic. A student at an American university is said to have removed the loop from his shirt when he started dating a girl, to show that he was taken. For her part, his girlfriend started to wear a scarf with the emblem of his university on it.

The cylinder on your laptop’s power cable

You’ve almost certainly noticed this little thing when using a laptop. This small but very important device is called a ’fer rite bead.’ It suppresses high-frequency noise in electronic circuits. Its design is incredibly simple: it has an insert made from fer rite which the cable is wrapped around.

The tiny hole in the window of a plane

Two pieces of plastic glass are used to make the window panes in airplanes. On its own, the inner glass pane could potentially shatter because of the significant difference in pressure between the plane cabin and the outside. The tiny hole allows the air to move between the cabin and the area between the two panes, thus equalizing pressure between them.

The extra eyelets on your sneakers

Few people pay attention to the extra eyelets at the top of their running shoes. Yet they should, because they were actually designed with a very useful purpose in mind: they’re meant to fix the shoes in place on your feet and prevent them from rubbing your ankles while you’re playing sport.

you might notice two extra holes on the inside of Converse trainers. They are meant not only to make the fit snugger but also to add ventilation to the shoe

The horizontal buttonholes on your shirt

Here is another mystery associated with your shirt' why are the button holes for the uppermost and lower buttons horizontal, while all the others are vertical? This has its origins in the fact that the buttons in these two places are more likely to come undone. A horizontal buttonhole makes this less likely compared to a vertical one.

The scrap of material that comes with new clothes 

These scraps of material are not, in fact, meant to be used to sew patches on your clothes. They’re actually meant to be washed with washing powder or bleach to allow you to check how your new clothes will react to certain kinds of washing/different chemicals. 

The hole at the top of the cap on a ballpoint

The opinion is widespread that the hole at the top of the pen caps on ballpoint pens is meant to allow air to flow through to the lungs if it gets lodged in a person’s throat. This isn’t quite the case. If anything gets stuck in someone’s trachea, it will cause the mucous membrane to swell in reaction. This gap helps prevent the cap from getting absorbed into the membrane. My life will never be the same now I know this!!!
