Just as this top hat wearing bird will never stop being thirsty, you'll never stop being amused by the repetitive actions of the Novelty Dippy Drinking Bird! Place him over a glass of water and watch as he swings up and down, appearing to take a drink. A fun way to teach kids some basic scientific principles, the bird moves when condensate from the fluid in its glass body accumulates on its beak. This makes the bird top heavy, causing him to tip forward. Then, the fluid rushes to the bottom, and the bird stands up again! The head and feet are crafted out of plastic.When the head of the bird is moistened with water, it will repeatedly?bend down?and appear to be drinking from a cup?of water in front of it. The dunking is due to the evaporating water, which cools the head reducing the pressure of the gas inside. The liquid inside the bird rises up from his tail towards his head, causing the bird to?bend down and appear to be drinking.?When the bird dunks, the liquid returns to its tail, and the process begins again. The novelty dippy drinking bird only needs water to run.
