Vapor Pressure: Drinking Bird - Introduction
This drinking bird is available in some novelty stores. The vapor pressure differential between the head and the base causes the liquid to rise in the neck. When the liquid enters the head, it causes the bird to tip over into the water for another drink. The bird's head is covered with a material that absorbes water. The base is closed at the top and so the only way that liquid and vapor can escape is through the tube which extends almost to the bottom of the base.
