Description

The beautiful and functional Galilean Thermometer is sure to impress anyone who comes to see it! This old school technology belongs to the 17th century, but it is an amazing way to show science in action and just a great desk curio for teachers or office workers!

The Galilean thermometer was not, in fact, invented by Galileo himself, but by one of his students in 1666. These stunning thermometers contain no mercury and work through the principle of buoyancy. The hand blown glass balls inside of the tube each have a particular density and when the ambient temperature changes, the fluid inside of the tube surrounding the balls will change too. The change in the density of the fluid affects the relative density of the glass balls. If a particular ball is now more dense in comparison to the fluid it will sink, but if it is now less dense than the fluid it will rise
