Newton’s Cradle




Product Description

This desk fidget is a true classic. Orignally created to demonstrate Newton’s law of momentum and conservation of energy, now it can sit on your desk as a fun visual and auditory sensory break! Simply pull back one of the spheres on one end and watch as it swings forward, hits the next sphere, and then the sphere on the opposite end will swing out and back in, starting the process all over! It’s fascinating to watch and comes with a satisfying, regular clacking sound from the spheres hitting each other.
