Once he starts drinking he won't stop!

Dip Drinking Bird's head in cold water and release it. Drinking Bird will bob back and forth while periodically taking a drink.

How does it work? It's the PRINCIPAL of THERMODYNAMICS my friend! The bird dunks because his head is wet and as the water evaporates, it cools the head reducing the pressure of the gas inside. As the gas shrinks, the liquid inside the bird expands, rising up from his tail towards his head, causing the bird to tip over and appear to be drinking. As the bird dunks, the liquid returns to its tail, and the process begins again. It's a small thermodynamic engine which ONLY NEEDS WATER TO RUN!

How to Assemble & Use:
• Insert the pivot into the openings at the top of the two so that the bird swings forward and back freely.
• Fill a glass with cold water. The height of the glass should be a little lower than the top of the legs.
• Put the birds head into the water and get it completely wet. Place the bird near the glass and he will begin drinking water by himself.
