Zorbing...

Have any of you heard of this...apparently its the new thing to do. I can't imagine rolling down a hill inside a big plastic ball. I need to see this in person.

Sphereing is the practice of humans traveling in a sphere, generally made of transparent plastic, usually for fun.
Sphereing is generally performed on a gentle slope, allowing the rider to roll downhill, but sphereing can also be done on a level surface, permitting more rider control, as well as on water. In the absence of hills, at least one vendor has begun constructing metal ramps[1]. Most spheres are constructed for a single rider, but some hold two or three. The longer runs are approximately half a mile. - thanks wikipedia
