Bounce as high as you can. How high could you jump on flat ground? Now jump on a trampoline. How high did you go that time? A lot higher right? So why is that? What make us bounce so much higher when on a trampoline compared to when on the ground? Simply put, it's the Potential and Kinetic Energy of the trampoline. The potential energy that is stored in the springs, along with the gravitational potential energy and the kinetic energy while you move, allows for a higher bounce.
Skyzone, a popular place to go and have a good time, is simply a room full of trampolines. You bounce from one trampoline to another, flip into a giant pit or foam, or even dunk a basketball on super high basket. One you could never reach on your own.
