Newton's Cradle is a classic desk toy that demonstrates the law of conservation of momentum. Pull back one or more of the balls, release them and the same number of balls will swing up on the opposite side. The balls will click back and forth until they stop. For every reaction there is an equal and opposite reaction!

Stands about 5.5 inches tall.
