Product Description
Long live the the amazing drinking bird!
It seems to defy scientific laws and stimulates perpetual motion discussions. Patented in 1946 by M V Sullivan, it is an example of a crude heat engine as it converts a temperature difference into cyclical motion.
Some useful information and classroom tips are available in the file below.
Can it do useful work? What principles are involved? How can students accelerate the cycle? How can you decrease the bobbing rate? Can you run it without water? and more.

Teach: evaporation, ideal gas law, capillary action, center of gravity, heat of evaporation, vapour pressure and more.
Age: 10+ (Note: This is not a toy and should only be used under close adult supervision due to the chemical nature of the liquid as well as the fragile glass construction)
