Zorbing

Also called globe-riding.

Wikipedia defines Zorbing as a recreational practice of humans rolling downhill in a sphere that is generally made of transparent plastic. I can't figure out how to put on the video that I found because it's in a different format yada yada but here is the link. Check it. I'm so doing it. The guys in the video have awesome english accents and the first thirty minutes are about a bunch of people running down a hill after cheese....? Pay attention to the girl in the purple sweater!
