Known as motion balance balls, these steel balls keep you entertained all day long. Newton's Cradle makes a great desktop executive gift. Draw back one or more of the balls and release.
Newton's Cradle is a classic! Every action has an equal and opposite reaction, science demonstrated simple and clearly.
The exact number of balls will sway up on the opposite side and the motion will repeat back and forth until it stops... a restful experience you'll enjoy.
