Weeeeeee!!!!

Mats loves to spin. He spins his top, he spins around in a circle, and his latest "game": running as fast as he can in a circle around me while I spin to keep up and try not to get dizzy and fall over. Mats is really taking spinning to a whole new level. Needless to say, spinning in the teacups at the Union Street Fair was a huge hit.

Is there a law of physics explaining why adults get dizzy long before kids do?
