This is the classic tabletop heat engine.

The glass body of the brightly colored bird contains a liquid that rises from the warm bottom to the evaporatively cooled top, and then spills back as the beak dips into the water to keep the head cool.

Can also be used to determine relative humidity, or modified to be a solar heat engine.
