Drinking Bird

This Drinking Bird – The Original is a classic and iconic toy that has been around for decades. It is an excellent way to have some fun and amusement, while also learning about the basics of thermodynamics. It is a fascinating product that can bring joy to adults and children alike.

The bird is composed of two glass bulbs connected by a metal tube. When you fill the lower bulb with water, capillary action causes the liquid to be drawn up into the head of the bird. As the liquid evaporates from its beak, the air inside cools, causing it to become heavier and pushing the bird’s head down. This causes more liquid to rise up the tube, creating a perpetual motion machine. This process is known as thermodynamics and allows the bird to maintain its bobbing motion without any external power source!
