Galileo Thermometer
The Galileo Thermometer is named after and idea Galileo Galilei had. A great scientist who lived over 350 years ago. Galileo cleverly discovered a method for measuring temperature by placing several precisely weighted balls in a cylinder filled with a certain fluid. He found that the balls rose or fell according to the current temperature, therefore he was able to determine the correct temperature.
How does it work?
Based on the principle that the density of a liquid changes as temperature varies, each of the glass balls individually weighted by partially filling the spheres with fluid. When the temperature rises, the liquid in the cylinder becomes less dense and the heavier balls fall slowly to the bottom.
How do you interpret the thermometer?
The lowest ball within the group at the top of the cylinder tells the correct temperature.
