We have wonderful styles of any Galileo thermometer you could possibly imagine at Digital Thermometers. A Galileo thermometer is designed primarily of a sealed glass cylinder, which contains a clear liquid substance. Sometimes the liquid is colored for an overall effect that is more pleasing to the eye.

The Galileo thermometer works by the scientific principle of buoyancy or resilience. Buoyancy determines whether objects float or sink in a liquid, and is responsible for the fact that even boats made of steel can float (of course, a solid bar of steel by itself will sink).

Though certain not as precise as more modern digital thermometers, if the weights of a Galileo thermometer differ—even by a slight amount The least dense part of the liquid is at the top and most dense part of the liquid is at the bottom of the thermometer, together they form a scale for measuring the temperature.
