Our colorful glass thermometer is based on Galileo's theory: in liquid, a body of fixed mass becomes less buoyant as the liquid temperature rises, and more buoyant as the temperature decreases-due to changes in liquid density. As the temperature changes, the multi-colored balls rise and fall within the liquid-filled thermostatic tube. The lowest sphere in the top group within the instrument indicates ambient temperature. Made of glass, measures 9" tall with five temperature indicators.
