Description
The classic executive desktop toy - in miniature form! And it works! This wire-framed Newton's Cradle measures 2-3/4" long, but it still packs that momentum-conserving punch when the balls hit each other. Simply pull back one or more of the balls and watch them strike the rest only to see a single (or more, equal to the amount you pulled back in the first place) ball fly out! This size is at a great price, too!
