The drinking bird works because of thermodynamics. The bird is made of a top bulb and a bottom bulb, separated by a narrow tube. Inside the bird is a liquid called dicloromethane, which evaporates at ...

The top-hatted “drinking bird,” once a fixture in science classrooms for demonstrating the basics of thermodynamics, is making a surprising comeback — as the inspiration for a new clean-energy ...

How a “drinking bird” engine converts evaporation energy into kinetic motion. How to use a triboelectric nanogenerator to convert kinetic motion into electricity. How to generate over 100 V through ...

The action of the “Drinking Bird” is stopped when it is covered with a large bell jar. It resumes its motion when the bell jar is removed. The demonstration can be used to illustrate the expansion or ...
