Is your Schwartz
big enough? You can train with the Spaceballs -- sorry, Spaceball Trampoline
, for only $700 (a total of $900 with shipping).
Movie references aside, Spaceball is an actual game, which Mercury program astronaut Scott Carpenter calls "the best conditioning exercise for space travel." Plus, it looks a lot like the game they play in "Battlestar Galactica."
The floor is a standard 14-foot trampoline, and the backboard is an angled trampoline as well. The object is to get the ball past your opponent, by throwing the ball through a netted tunnel while bouncing up and down.
We're planning on picking one up as soon as they have a demo between Barf and Pizza the Hutt
