What is it for? Discover the hidden features of these 7 commonly-found items
We use some items almost daily: smartphones, notebooks (with margins), hats and exercise clothing are just some examples. But have you ever wondered why these objects are made the way they are?
In fact, there are a few peculiarities/features about these objects that not everyone knows about. Indeed, behind the shape of many objects, there is often a design need or intention that many still need to discover. Find out about these features by reading on:

On the external frame of any smartphone that has a metal body, we can find plastic strips (usually at two different points). These are not there for an aesthetics, but to function as antennas - or, more accurately, to create a space where the radio waves can enter the device.
At school, we got accustomed to using notebooks with margins, often scored in red. These margins are not just for learning how to write neatly (or rather, this wasn't the original purpose). The reason for having a margin is ancient and curious: in the past, it was not uncommon for books to be nibbled by mice and rats. The margin was used to protect the text on expensive books, creating a "buffer" between the text and the pest's teeth.
Wool caps/hats are often equipped with a colorful pompon at the top. But, in fact, this pompom was originally added to stop sailors from bumping their heads against the low ceilings of their ships!
Sports shirts: many sweatshirts of a sporty or casual nature have a small triangle of fabric embroidered under the central part of the neckline, in the front. This originally served to make the neck itself more elastic and also to better absorb sweat.
A cardboard container of French fries - like those you can get at McDonald's - often has a flap on one side with a rounded edge. If you bend it donw, creating a 90° angle, it becomes a ketchup tray!
Baby rompers have folds on the sides of the neckline, near the shoulders: this is used to make them pass smoothly over the infant's legs and arms!
If you see a hiking backpack that has a bump like this on the side of the buckles, it is a whistle that can be used in emergencies.
