The Galileo Thermometer is a unique functional thermometer. The spheres will float up and down according to changes in the temperatures. When the temperature rises the spheres will sink and inversely when the temperature falls the spheres will rise due to changes in the specific gravity of liquids. You always read the lowest of the floating temperature tags to determine the correct temperature.
Starts at 60ºF and goes to 100ºF. Contains 11 spheres in 4º increments. Galileo itself is 12". Full legnth with metal encasing is 17". The chain shown for hanging the Rustica in the images is not included with purchase. Sphere colors are red, yellow, and blue.
thumbs up if you come from the microwave show!
