Original Drinking Bird

A classical science toy from the 1960's!

Great for science lessons on evaporation and condensation. Perpetual motion for perpetual fun. Great conversation starter!


Our drinking bird bobs his top hat and beak into a glass water again and again. When the funny bird gets going, he appears to be a perpetual motion machine, but actually it is an example of an evaporation heat engine.
