Economic equilibrium

Economic equilibrium is like a see-saw. When one side of the see-saw is very heavy, it will be tilted and the other side will be up in the air. The same thing works for economics - when there are too much of something (like too much supply) and not enough buyers, the prices will go down until the heavy side is balanced and everyone is happy. This is called economic equilibrium - when all the buyers and sellers have the same amount of stuff and prices stay the same.
