None of the Above: Season 1, Episode 18 - ProjectFreeTV

1 - 18:

Tim Shaw shows us how a harmless pingpong ball can pack a mighty punch, how dominoes can be used to create a powerful chain reaction and the amazing science behind the Slinky in mesmerizing slow motion. Tim also cooks up a large eggs-periment with an ostrich egg, and tests the power of rotation in a head-spinning stunt. Finally, we have a speedy short-circuit race showdown with four very different contestants — a runner, a horse with rider, a pushbike and a quad bike.
