I just watched this video, and now want to rent one of these huge, inflatable balls known as a Zorb as soon as possible and play with it down a purpose-built track. The video’s silly, but it looks like a fun, only slightly hazardous, way to spend an afternoon with some friends.
A few locations for this kind of tomfoolery are listed on the Zorb website. Time to pull together a posse and recreate the antics!
