TheGag 3 Pack of Magic Drinking Birds 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. Great for science lessons on evaporation and condensation. Perpetual motion for perpetual fun. Great conversation starter! New and Boxed
