Drinking Lucky Bird

Description

Note: Liquid color may vary. This classic novelty toy is a scientific wonder, using the properties of themodynamics to keep it in constant bobbing motion. Once your lucky bird starts drinking, it won’t stop! 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. A fascinating desktop or tabletop marvel!
