Big Apple Circus: Part Two

I'm not even sure how to talk about this Romeo and Juliet-splits-on-two-horses act.
Well, lets just leave it at then, shall we?

So while most of the acts were kinda lame, this one was BALLER! Using just their body weight alone, these two performers spun around and around the axis at dizzying speeds, and at the apex of the spin they would JUMP (!) to increase the momentum. And potentially fall out of the circle. It was nutty and even though in reality it was the same thing over and over (and over and over...) I was completely memorized.
At the end of the act the performers ran around the outside of the circle- really really fast- while the thing was spinning around. UGH SO COOL!
