Galileo Thermometers are magnificent creations that make Galileo's 400 year old principle of relative density a functional reality. Each Thermometer is encased in brilliant glass with many multi-color floating balls. A gold tag that displays a temperature in Fahrenheit hangs beneath each ball. The Galileo Thermometer is the point at which art meets science.

Galileo Thermometers are precisely manufactured. Each of the liquid-filled floats weighs exactly .006 grams more than the one above it. Precise measurements of the liquid filled balls ensure a stately and orderly procession of ups and downs as the temperature changes.
