The Galileo thermometer, invented by astronomer Galileo Galilei, works mainly on the buoyancy principle. It is used to determine the capability of an object to either sink or float. It consists of glass spheres that move up and down as the temperature changes.
Galileo thermometers are glass tubes filled with floating colorful spheres. They're based on Galileo Galilei's invention, the thermoscope. Changing temperatures cause the colorful orbs to either sink or float inside the glass tube.
The Galileo thermometer works on the principle that as the temperature of a liquid changes, so does its density. When the temperature changes, the liquid either expands or shrinks.
A Galileo thermometer (or Galilean thermometer) is a thermometer made of a sealed glass cylinder containing a clear liquid and several glass vessels of varying density. The individual floats rise or fall in proportion to their respective density and the density of the surrounding liquid as the temperature changes.
