Display the temperature beautifully outdoors with this hanging Galileo Thermometer. Invented in the late 16th century by "the Father of Modern science", Galileo Galilei, this attractive glass thermometer is held in a protective steel hanger and works through the principle of buoyancy. Just read the correct temperature from the gold tags which hang from carefully crafted, floating glass balls. Temperature variance changes the density of the clear liquid and the glass balls react by sinking or floating. This will surely make a fascinating gift for the scientist in your family and looks wonderful hanging on your porch or in your kitchen window.
