Searching for the exact temperature measurements, the brilliant Galileo Galilei made a fascinating discovery. When floating in liquid, a solid object of a standard density, size and weight will "float" up or down within the liquid as the temperature rises or falls.

Galileo created different glass spheres that differed in weight and density of the liquid inside each small sphere. As the interior temperature of each sphere changed, the lowest of the floating spheres in the upper part of the cylinder indicates the correct temperature. To make temperature identification easy, each small floating sphere has a temperature indicating medallion attached.

The production of this instrument is extremely complicated. Each temperature ball is calibrated to exactly .36 degree F. Two glass spheres differ in weight by only 6/1000 of a gram. Temperatures are marked in Fahrenheit.

Gem of the Day" is offering this very unique gift in three sizes. All three sizes contain multi-colored temperature spheres to indicate the temperature. The small and medium sizes have five temperature spheres, marking the temperature in 4 degree increments. The Large model has seven temperature spheres, each set at a two degree increment. All are made for indoor temperature measurement and direct sunlight or heat should be avoided.

Gem of the Day" is pleased to make these beautiful Galileo Thermometers available at a remarkably low price.

We will carefully pack your thermometer for shipping. And we will gift wrap it at no charge, if you wish. All major credit cards are accepted.
