Bowling Ball Pendulum

This experiment consists of a HEAVY bowling ball pendulum hung from the ceiling and a volunteer standing with their head against a wall. The bowling ball is pulled up to the volunteers chin and released, it swings across and back towards the volunteer and just misses hitting them. It's very difficult NOT to flinch when this ball comes at you but it actually misses by about an inch or more. This experiment is useful for discussing conservation of energy, potential and kinetic energy and frictional losses.
