Tap-powered paddle wheel

Explore water power under a running tap

Eight paddles round a hub: push a chopstick through the centre, hold both ends under a running tap or a jug and the wheel spins, faster as the stream grows. Children discover cause and effect, then lift it higher or lower to see how the drop changes the speed.
