Let it roll

Ball nuts have a new outlet for indulging spherical fantasies -- zorbing. Brought to you by the sensory-deprived souls who gave us bungee jumping and river sledging, New Zealanders with too much downtime, zorbing takes you into the game of globular physics. You are no longer a ballplayer; you are the ball. The sport involves the insertion of a human into the inner sphere of a giant double-skinned orb with air holes. A roll down a hillside sets off involuntary Olympics-style tumbling within. If you’ve ever wanted to flip like Mary Lou Retton or spin with the wild abandon of sneakers in a Maytag, zorbing may be your thing. No skills required, other than ability to hold down food.
