This metal is too bouncy

A little while ago I made something called an atomic trampoline, and I think it's pretty cool. This is because when you drop something on it like a ball bearing, it just keeps on bouncing like it's never going to stop. What I've been really wanting to do though is take two of the trampolines that I've made, and see if anything weird happens, if I try bouncing a ball bearing between them. #shorts
