Galileo Thermometers

$70.00
SKU: Galileo


    Art meets science in this colorful glass thermometer. In 1593, Italian physicist Galileo invented a thermometer based on the principles of relative density. Individually calibrated weights containing a mixture of ethanol and dye float in a sealed tube with de-aromatic oil where they rise and fall with the temperature and the resulting changes in liquid density.
