Newton’s Cradle Motion Desk Toy

Swingin’ Desk Toy Newtonian demonstrator for science teachers. Mindless play for the rest of us. This is a shiny, nicely balanced, high-performance example of the classic Newton’s Cradle – a ball on one end of a row of (5) suspended, barely touching balls swings into the others, and the ball at the opposite end reacts to the collision. The 11/16″ dia balls in this small version (all-metal frame 6-1/2″ high x 4″ x 4-1/4″) will collide more than 30 times. Awesome. Even more awesome that we paid someone to count the bounces just for you!
