This liquid is also highly volatile, meaning it evaporates rapidly due to weak intermolecular bonds in the liquid state.

How does the famous drinking bird work?

The drinking bird is a heat engine that exploits a temperature difference to convert heat energy to a pressure difference within the device, and performs mechanical work. The higher vapor pressure in the warmer base pushes the liquid up the neck. As the liquid rises, the bird becomes top heavy and tips over.

How do you make a drinking bird that rocks?
