This Galileo thermometer makes a beautiful addition to any home. It is named after Galileo Galilei, and works off his principle that the density of a liquid changes in proportion to its temperature. It is a sealed glass cylinder that is filled with liquid, and contains 7 glass vessels of varying mass. The vessels rise or fall as the temperature changes. No power required, and makes a great conversation piece as well as being practical.
