Replacement Ring & Screw for Hall's Friction Cars
One replacement ring and one screw for Hall's friction cars. The ring is 2.75 inches in diameter and about 0.3 inch high; the screw is about 1 inch long. Fitted to the cars, the rings make them rebound elastically, so total kinetic energy stays the same before and after a collision.
