Outdoor Galileo Thermometer by Global Village Glass Studios

This thermometer works on the principle discovered by Galileo that the density of a liquid changes as temperature varies. Each of the glass balls is exactly weighted by partially filling the spheres with liquid. when the temperature rises, the liquid in the glass cylinder becomes less dense, and the heavier balls sink slowly to the bottom.

Thermometer is suspended by a black metal and plastic structure allowing it to hang in your favorite area of the garden! Please note: although it is able to hang outside, we still advise for best results and longevity, not leaving it out in cold weather and keeping it out of direct sunlight.

Approximately 14 inches long, handmade glass.
