Named after Sir Isaac Newton, the Newton's Cradle is a device that demonstrates conservation of momentum and energy via a series of swinging spheres. When one on the end is lifted and released, the resulting force travels through the line and pushes the last one upward.
Demonstrating Newton's Third Law of Motion - for every action there is an equal and opposite reaction. Science has never been so entertaining! The Newton's Cradle a fantastic addition to your office desk or school classroom.
The perfect desktop boredom buster! Just lift and release one or two balls and see the reaction.
