Shirt Loops
There are loops on some shirts, but why? Apparently, this was something that started with the men of the Navy. When they are out at sea, there are not a lot of places to store their clothes, so they started hanging them on hooks instead. In the ‘60s, college students did this when they went to the gym as well.

Colored Toothpaste Squares
Why is there a green, black, red, or blue block at the bottom of the toothpaste? This is called an “eye mark”. They are added to the tubes because they inform the assembly line machines which part should be cut and folded. The tubes of toothpaste would not be separated if these things did not exist.
