One way would be to put rubber bands around a bowl, if the bowl deforms, taped many together. It isn't the best design, but it's a start.
I am just curious but how far does this bouncer bounce?
Alot of success in this is just little changes. They can make a huge difference.

Not very far.

our catapult uses rubber bands, and fling practice golf balls.

How'd you do it? What's your design for cantilever?

Not that far, but you could make it higher by adding cups and bowls. It's not the best.

I can't tell you much because my partner is kind of.......... you know........... But it uses lots of popsical stick for the arm. Tons of rubber bands too.

Hint: Get a Great base and build off of that.

Hmmmm.....We already tried that, but it isn't working enough for us...
We've also tried making some sort of trampoline, but that still has to be tweaked a little more....

Any other suggestions?

anything we've tried with rubber bands just deforms no matter how strong we make it. our bouncer involves no rubber bands and shoots around 2ft.

also, does anybody know if a sort of spring loaded bouncer w/ a trigger that the balls hits as you drop it, and the trigger has to be reset after each bounce is allowed
