17 Inch Galileo Thermometer

 

Italian astronomer and physicist, Galileo Galilei (1564-1642), discovered that the density of liquid changes with temperature variations. This discovery led to the creation of the Galileo Thermometer. The Galileo Thermometer is made of a glass cylinder that is filled with a liquid. Inside the cylinder and floating in the liquid are liquid-filled glass spheres that each have an imprinted temperature reading medallion that are calibrated counterweights. These weights rise or sink in relation to the density inside the cylinder. Since the density inside the cylinder is relative to the temperature outside the cylinder, these counterweights can be used to determine a room's temperature. When the temperature rises, the liquid in the cylinder becomes less dense and the spheres sink slowly to the bottom. When the temperature falls, the liquid in the cylinder becomes more dense and the spheres slowly rise to the top.

To read a Galileo Thermometer, simply examine the counterweights. The lowest floating glass sphere gives the temperature of the room. If all of the spheres float to the top, it means the temperature in the room is under the lowest floating sphere. If all the spheres sink to the bottom, it means the temperature in the room is over the highest sphere. Measures temperatures from 60 degrees F to 96 degrees F.

This thermometer also functions as a cool work of art that can be displayed on a shelf or table in your home!
