Ninja balls, seismic accelerator
Ninja Balls are a set used to demonstrate the concept of momentum transfer in a simple and visually compelling way. When the set is dropped from a low height, you can observe how the kinetic energy is transferred through the balls, causing the top ball to bounce significantly higher than its starting point. The set consists of five balls and a pair of plastic safety glasses, which should be worn during the experiment to protect your eyes.
