Rocking Stork: this species of drinking bird toy comes from the Czech Republic where each is crafted in blown glass by an artisan. This classic physics toy is a functional heat engine- cooling by evaporation at the head/beak leads to lower pressure in the top bulb, the pressure in the bottom bulb pushes the dichloromethane fluid (here dyed red) up the neck making the bird top heavy and the bird tips over dipping its beak and letting the fluid return to the bottom bulb. The process repeats, and a

Drinking Giraffe Heat Engine: a rare vintage version of the famous drinking bird heat engine- but in the form of a long necked mammal! With four legs instead of two the physics is the same- cooling by evaporation at the head leads to lower pressure in the top bulb such that the volatile fluid rises up the neck making the giraffe’s neck top heavy and the critter tips over dipping its face in the water and letting the fluid return to the bottom bulb. The process repeats as long as the top stays we

Drinking Bird Engine Experiment: what happens if you feed a drinking bird alcohol? This experiment compares the drinking rate (time per one full engine cycle) of two identical bird devices- but the glass on the left is filled with 70% isopropyl alcohol whereas the glass on the right contains tap water. After wetting the tops of both birds we count how many times each one “takes a drink” over a 5 minute duration (shown at x6 speed). This classic physics toy is a functional heat engine where cooli
