Galileo Thermometer
View Larger Image
This elegant and timeless instrument is based on Galileo’s theory that a fixed mass’s buoyancy is inversely related to the liquid temperature of which it is suspended in. Watch the liquid filled spheres rise and fall in the column based on the ambient temperature. Each sphere is fixed with a Fahrenheit metal tag. The lowest sphere in the top of the column indicates the ambient temperature. Available in the sizes listed below.
