Help me figure out how to build a small mechanical-action pump (to operate a small fountain). My daughter wants to figure out a way to build a fountain that would operate for, say, 5 minutes, with no batteries or electricity. Volume could be very very small. Windup, counterweight-driven, anything-- the more elegant-looking, the better.
Why? because it's a challenge, and would help a teenager follow up on a spark of curiosity and creativity!
