Newton's Cradle - 4 inch, Plastic Base, Color
Newton's Cradle is a classic! Also known as balance balls, these steel balls keep you entertained throughout the day. Pull back one or more of the balls and let them drop down. The same number of balls will swing up on the opposite side and the clicking will go back and forth until it stops... a soothing experience you'll enjoy. The bright neon color will brighten up your workspace.
