Newton’s Cradle Balance Balls
Newton’s Cradle Balance Balls is a classic desktop science toy that is a perfect blend of science and art. Also known as Balance Balls, Newton’s Pendulum, and Newton’s Balls. This toy works through the use of momentum and gravity. Pull a ball on one end and release. After hitting the rest of the balls, a ball on the other end will be forced to the same height as from where you dropped the original ball.
