Galileo Thermometer
And you were expecting a Bohemian Rhapsody joke? Wrong!
The Galileo Thermometer is named after the Italian Physicist, Galileo Galilei, although surprisingly, the basic principal precedes Galileo by a long time and can be traced right back to Archimedes. So there.
The Galileo Thermometer consists of a sealed glass cylinder containing a clear liquid and several glass spheres that look pretty.
If we plonk our Galileo Thermometer into a hot room, the increase in room temperature will cause the density of the liquid to decrease. This will cause some of the glass spheres to sink, because their density will be higher than that of the liquid.
The glass sphere which remains free-floating in the clear liquid must be the same density as the liquid; therefore, this is the sphere you must read to know the temperature of the room!
Confused? Don’t worry!
All you really need to know if that the beautiful spheres create a temperature scale.
The Galileo Thermometer is the classiest and most intelligent thermometer created and those qualities can only rub off on its owner!
