The classic "executive" desk toy, Newton's Cradle demonstrates the concept of kinetic energy.
Product: Newton's Cradle, named after the English 17th-century scientist Sir Isaac Newton, is a device that demonstrates conservation of momentum and energy using a series of swinging spheres. When one sphere at the end is lifted and released, it strikes the stationary spheres; a force is transmitted through the stationary spheres and pushes the last sphere upward.
