Drinking Bird

It may have been called by many names, the Drinking Bird, Drinking/Dunking Bird, Drinking Happy Bird or even Dippy the Drinking Bird Toy but almost everyone remembers the drinking bird, a hard-to-find toy with at least a twinge of nostalgia. Now he's back, disguised as a great physics demonstration of heat and thermodynamics. This lugubrious little lorikeet dips his beak into a glass of water as evaporative cooling induces the rise of a volatile liquid from his tail toward his head. As he dunks, the liquid returns to his tail, the bird rises, and the process begins again. Is this drinking/dunking bird mad? No, he just knows that hands on repetition is the best way to learn physics! Colors may vary.
