Work extremely well with the sonic ranger motion detector. Also nice for qualitative momentum conservation demonstrations. Neodymium magnets are mounted on one end of the carts for elastic collisions. Velcro is mounted on the opposite ends and used for inelastic collisions. A spring loaded plunger is on each cart a...")
