This novelty is a classic scientific wonder, using the properties of thermodynamics
to keep it in constant bobbing motion
Do you understand the complex relationship between chemistry and physics that makes this simple heat engine operate?
It is a perpetual motion machine, but more
- low pressure causes liquid to rise
- weight of liquid causes a drop in the drinking bird's head
- tilted head causes reequillibration of pressure &the liquid to flow back down
