Moon Sphere Bouncer

A Moon Sphere Bouncer (MSB) is like a hamster ball for people.

Because people are more concerned than rodents about life and limb, an MSB is actually made up of two soft vinyl spheres, one inside the other, like a bubble boy nesting doll. The outer layer takes all the impact, while the smaller, internal sphere protects the precious human cargo.

After you have hopped inside, someone then pushes you down a hill or into the surf!.

For extra absurdity, just add water. If you pour a bucket of water into the interior sphere, you spend the entire ride gliding about in your own miniature wave pool. Hamsters are missing out.
