Newton's Cradle Balance Balls Science Toy
This classic desktop display piece has become a must have for office décor. Swing one steel marble back, let it go, and watch as kinetic energy causes the one on the opposite side to swing the same distance! If you’re feeling saucy one day, try swinging two or three at once- just don’t pass out from the excitement!
