The classic Newton's Cradle with a unique, Z-shaped frame!
Named after Sir Isaac Newton, the discoverer of the laws of physics, the Newton's Cradle demonstrates the law of conservation of momentum and energy via a series of swinging spheres.
When a sphere on one end is lifted and released, the resulting force travels through the other spheres in the line and launches the opposite sphere upward!
Measures: 4.75 x 5.75 x 6 inches.
Contains: one Newton's Cradle.
