Glassic Gifts 7" Tall Hanging Galileo Thermometer Ornament (64˚F - 80˚F Range) What is a Galileo Thermometer and how do I read it? A Galileo Thermometer is a sealed glass vessel filled will glass orbs that are suspended in liquid. As the temperature of the liquid changes, the orbs will rise and fall within the vessel to display the current temperature within the thermometers range. Under normal conditions, the orbs will separate into two groupings. To read the thermometer, you must observe the lowest orb within the top group. The temperature imprinted on the tag of that lower orb will be the current temperature of the liquid (within 2˚F accuracy). If all of the orbs are at the bottom, the liquid is hotter than the maximum temperature and if all the orbs are the top, it is hotter.

Galileo Galilei (1564 - 1642) was an Italian physicist, mathematician, astronomer, and philosopher who played a major role in the Scientific Revolution. His discovery that the density of a liquid changes in proportion to its temperature, inspired the invention and explains the accuracy of the "Galileo Thermometer".
