Galileo Thermometer

Here's a Galileo thermometer! It's a decorative and functional piece that uses the principles of buoyancy to measure temperature. The glass cylinder contains liquid and several glass spheres of varying densities. Each sphere has a metal tag indicating a specific temperature. As the temperature changes, the spheres rise or fall, indicating the current temperature. It's a unique and interesting item for your home or office!
