Newton's Cradle - 3.5 inch - Plastic Base
The Newton's Cradle is a classic desk toy. Also known as balance balls, the clacking of the steel balls will keep you entertained throughout the day. 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 after a few seconds. This miniature Newton's Cradle is great fun for the office.
