[QUOTE="Calamity, post: 2104541, member: 112048"] Just for a fun experiment, buy a kid's hula hoop (hollow rigid plastic toy) and cut it in half. Obtain two metal balls of the same size (Walmart sporting goods) that will roll through the hollow hoop. One ball should be steel (ball bearing/slingshot ammo), the other lead (fishing sinker). Mount the half-hoop on a piece of plywood with both open hoop ends pointing up. Drop each metal ball into one end of the hoop and mark how high it rises in the other end. The heavier ball will rise higher, retain velocity longer, etc. Teach your kid about inertia, ballistic coefficient, etc. Make a memory....... [/QUOTE]
