Newton's Cradle is a classic desktop toy that has stayed popular through the ages. When a ball at one end is lifted and dropped, the middle balls remain still as the ball at the opposite end swings out the same distance, demonstrating Newton's laws of conservation of momentum and energy. Sleek and stylish in appearance, educational and entertaining in function, Newton's Cradle makes an excellent gift for students, co-workers, executives and all.
Recommended for ages 5 and up. Stands 4.5 inches tall on a black base. Made of plastic and may get tangled with kids use.
