Hidden Features Of Everyday Items

Rulers

Rulers can be found in almost every household, and while their purpose is rather obvious, it is the purpose of the small hole at the end of rulers that is lost on most. While some have suggested that it's there so you can draw a circle, it isn't, and the need to draw a small circle rarely seems to occur. As it turns out, the purpose of the hole at the end of the ruler is so you can hang your ruler up.
