Galileo Thermometer

The listing

This functional yet decorative piece will add color and interest to your home or office. The centuries-old design is based on the law of physics and operates on the principle that as the density of a liquid fluctuates the temperature changes. The floating weighted bulbs rise or fall indicating the current temperature. Blown-glass bulbs filled with red, yellow, green, and blue liquid dye include metal temperature identification tags that display the current degree. Great conversation piece!
