So after realizing the buoyancy of the mushroom ball, we started speculating how far it would go if we bounced it outside. It just so happens that Shabu Zen is located behind a parking lot. So I wrapped the bouncy ball in a napkin and we experimented in the lot. I kid you not, the mushroom ball bounced all the way across the lot, through several puddles, and when we caught up with it, we realized that it had still retained its basic shape.
