Galileo Thermometer: In 1593, Galileo invented the rudimentary water thermoscope, which allowed temperature variations to be measured for the first time. In a vessel containing bulbs of various masses, with individual numerical markings, the water's buoyancy changes with the temperature. Some bulbs will sink while others float; the lowest bulb indicates the correct temperature.
Liquid inside is ethanol, the dyes are paraffin.
Sit back and watch this rainbow spectrum of glass orbs rise and fall-- who knew you could be dazzled by degrees? Includes metal tags presenting both Celsius and Fahrenheit and a sturdy wooden base.
