Einstein's Drinking Duck

£ 20.99
Perhaps one of the best-known scientific toys in the world, our Drinking Duck is a heat engine that mimics the movements of a bird drinking from a water source. They also known as a Happy Drinking Bird, Dunking bird or even an Insatiable birdie. If you regularly fill its glass with new water, the bird will forever carry on sipping, seesawing back and forth.

Einstein’s Drinking Duck is very similar to a hand boiler and the liquid inside works on a similar principle, the key difference is it converts the rising liquid into mechanical energy to keep the bird drinking for days on end!
