Galileo Galilei, the pioneer of modern astronomy and physics, discovered when a liquid's temperature increases, its density decreases. Based on this principle, the colored glass bubbles rise and fall as the ambient temperature of the room changes. When the room warms, the balls fall from the top. When the room cools, they will rise from the bottom. This 11.25 inch high, 2.25 inch diameter Galileo thermometer is made of fluid filled clear glass and colorful fluid filled glass spheres with temperature tags that range from 64 to 80 degrees F. It is a stunning accent piece and a functional work of art.
