Water Timer

Build an animated timer that runs on water power!


Construct a working water wheel that spins as gravity pulls water through a spout, then watch the energy transfer to a cuckoo bird automaton. Fill the top cup, slide open the flow gate, and your two-minute timer kicks into action: the wheel spins, the figures move, and a duck bobs up in the bottom cup as the dipper fills and tips. Engineering technology, built by you.
