The Waterball is a giant ball made of transparent plastic. A person gets in it, has the Waterball inflated, gets zipped inside, and then goes out on the water to float, lay or roll around like crazy.
One question I had about the Waterball was, how long until you run out of air? The answer is, don't stay zipped in there for longer than 30 minutes.
Looks like it would be fun to try, but then, at the same time, it looks tormenting.
Take a look at what I mean...
