Zorb Ball is the sport of rolling down a hill or grassplot inside a giant inflatable ball. Its great for using down local hills, parks, play areas.
The Zorbonaut is strapped into a harness and rolls down the hill. This gives you maximum G force as you tumble head over heels. There is a sensation of weightlessness at the top of the Zorb®, and the view of green grass followed by blue sky followed by green grass followed by blue - green - blue - gree - blu - gr - bl-gbgbgb. Stop let me out. I want to do it again.
