The drinking bird is one of the wackiest inventions of all time, the strangest thought about this simple toy is how it works. The drinking bird is made of two glass balls with a glass tube passing between the balls. In the center of this tube is a bracket securing the bird to a pair of legs. The two balls and the tube are all hollow. A tube that runs through the outer tube ends just before the bottom of the lower tube. At one end of the bird is a beak-like object, the beak and head are covered with a felt-like material. At the lower end of the bird, in the cavity, there is a blue liquid. The liquid fills the lower cavity to about one-third of its capacity. Another feature that the bird also possesses is a top hat and tail feathers which serve no other purpose than to be purely aesthetic. The process of the bird drinking is very repetitive, once the head and beak are wet the bird continues to rock back and forth. and then say that the water level goes below the spout. The bird's starting position is head down. Once the bird swings, it continues to swing, for about eight swings back and forth. With each rock, the head goes lower and lower as the liquid rises up the inner tube. At the top of the tube, liquid is stored. When the bird fetches water again, the internal liquid flows to the bottom. One of the hardest things to notice about this process is the vacuum breakdown that occurs when the bird descends to drink. This process then repeats to indicate that the water is flowing out of reach of the birds. This astonishing process raises many questions. Some of the most important are: What is the purpose of the felt material and fluid present in the bird? Which process...... middle of paper ......e more visible and better (Drinking bird.) The drinking bird is a marvel of a child's toy. The processes going on inside are basically easy to understand, but because of the way they all work together, they are more difficult to understand. In the simplest terms, its evaporation and condensation in a confined space. Works CitedDipping Bird. (nd). Retrieved from http://www.exploratorium.edu/wsw/progress_snacks/dippingbird/ Gillespie, C.
