Drinking bird toy that keeps drinking for hours once started. It works by the cooling effect of the water evaporating from the birds beak. The bottom of the bird is slightly warmer (room temp), and the air in the bottom builds pressure forcing the liquid up the neck. The head is cooler from the water evaporating causing a vacuum, pulling the liquid up the neck. Once it becomes top heavy, it tips forward and the tube in the body raises above the liquid level allowing it to catch an air bubble which rises to the head. This air bubble is room temperature and is already expanded, when it reaches the head it immediately begins to cool and condense which continues the vacuum for the next cycle again pulling liquid up the neck.
