Galileo Thermometer – Floating Glass Balls Fahrenheit Temperature Indicator – Fun and Decorative (15″ Inches High, 7 Multi Colored Spheres)

This gorgeous Galileo thermometer is a murals with blown glass balls of varying colors in a delicate blown glass cylinder
The glass balls upward thrust and fall throughout the liquid-filled cylinder to reflect changes within the temperature, and every ball has a small charm to read the temperature
Attached to every bubble is just a little metal tag that indicates a temperature. These metal tags are calibrated counterweights. The weight of every tag is reasonably different from the others
The Galileo thermometer consists of a sealed glass tube that may be filled with liquid and a few floating bubbles. The bubbles are glass spheres filled with a colored liquid mixture
As the temperature of the air out of doors the thermometer changes, so does the temperature of the liquid surrounding the bubbles. As the temperature of the liquid changes, it either expands or contracts, thereby changing its density
