Drawing of the original patent for the Drinking Bird. M. V. Sullivan, U.S. Patent 2.402.463 (1946).
It was invented by Miles V. Sullivan in 1945 and is a very intriguing object, since it is capable of simulating the movement of a bird drinking for many hours or even days.
The bird drinker is an example of the properties of thermodynamics, converting thermal energy into mechanical energy.
As a curiosity, the Drinking Bird appears in several episodes of the American series of animation "The Simpsons" and in the popular "Mad Men".
It is important to improve its operation, both the liquid containing the bird and how deeply the tube is inserted into the lower bulb. Volatile liquid, usuallyCF3CHCl2, has a boiling point of 28 ° C close to the ambient temperature, which facilitates the process of transfer of temperature by evaporation. And that pipe reaches almost to the bottom of the liquid in the bottom bulb, so the fluid pressure acting on behalf of the process. If this were not the case, the pressure difference may not be sufficient to raise the liquid up to the head.
Please note that this product is not a toy and is not intended to be used by children under 8 years old. It contains methylene chloride, and can stain clothing and other surfaces. Do not swallow liquids or allow to come into contact with the eyes or skin. Keep away from open flames or other heat sources.
