This Galileo glass thermometer measures the indoor temperature of your room, while looking like a piece of art. It's sure to garner tons of compliments and start conversations when guests come over to visit. This versatile indoor temperature thermometer takes its name from Galileo Galilei, who discovered that liquids change density as the temperature changes. Based on this principle, the colored glass spheres inside the item have been precisely weighted so they respond to changes. When the temperature rises, the liquid inside the Galileo thermometer becomes less dense and the colored spheres floating inside will sink towards the bottom. When the temperature of the room cools, the process is reversed and the spheres will rise from the bottom.
