Kinetic Art Perpetual Motion Rolling-Ball Desk Toy

What reviewers are saying

An electronically powered rolling-ball desktop gizmo sold as a satisfying science-gadget office decoration; like all such toys it runs on batteries rather than true perpetual motion.

• Wikipedia — Clarifies that true perpetual motion is impossible, so these toys require an external power source such as batteries.

• Amazon — Listing for a non-stop rolling-ball kinetic motion simulator marketed as a physics gadget and desk decoration.
