Galileo Thermometer - Floating Glass Balls Fahrenheit Temperature Indicator - Fun and Decorative (17.5" Inches High, 10 Multi Colored Spheres)

This elegant Galileo thermometer is a piece of art featuring blown glass spheres of assorted colors within a fine blown glass cylinder. The glass spheres ascend and descend inside the liquid-filled cylinder to indicate temperature variations, and each sphere carries a small charm to display the temperature. A tiny metal tag is attached to each bubble, denoting a specific temperature. These metal tags serve as calibrated counterweights. The weight of each tag varies slightly from the others. The Galileo thermometer is composed of a sealed glass tube filled with liquid and multiple floating bubbles. The bubbles are glass spheres containing a colored liquid mixture. When the temperature of the air outside the thermometer alters, the temperature of the liquid surrounding the bubbles changes accordingly. As the temperature of the liquid shifts, it either expands or contracts, thus modifying its density
