Known as the Drinking Bird, Drinking/Dunking Bird, Drinking Happy Bird or even a Dippy Bird. Whatever you call this loveable little drinking bird toy it is back and 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.
