Drinking Bird A rather dumb looking 6" bird with a felt covered head and has plastic feet. Worse, he cannot get his fill of water. You buy the drinks.

Drinking Bird A rather dumb looking 6" bird with a felt covered head and has plastic feet. Worse, he cannot get his fill of water. You buy the drinks.
Fluid inside condenses from the evaporative cooling of the water off the bird's beak, making it top heavy and dunking it back into the water. The condensate rejoins the liquid pool in the bird's bulb, and he tips up again. Process continues indefinitely.
Children are fascinated by the bobbing bird, and the educational possibilities are great. But they should watch it, not fondle it!!
Great for school science experiments, tricks, office desk toys and everyday fun!
