Newton’s g-ball
The ball contains a digital stopwatch that can show the time between 0.01-29.99 seconds. Hold down the key and the time will reset. Timing starts when you release the ball and stops when it hits the ground / floor. The mechanics are well protected and the screen is sharp, but the ball must land on a soft surface such as a pad/mat/turf. Maximum drop height is approx. 12 m, friction against air is about 5%.

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.
