Drinking Dipping Dippy Bird
EZ Magic/Robbins
$14.99
This classic novelty is a scientific wonder, using the properties of thermodynamics to keep the bird in constant bobbing motion.
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 birds bulb, and he tips up again. Process continues for days.
Color inside bird may vary. Measures 6.9" x 2.2" x 1.9".
