C&H Solutions Galileo 7 inch (17.78 cm) Glass Thermometer with 4 Multi Colored Spheres in Fahrenheit and with Gold Tags

These unusual thermometers contain colorful orbs which rise and fall to indicate the current temperature. Crafted of high quality glass and individually calibrated to achieve an accuracy of 2 degree, these thermometers are timeless works of art. The tag on the lowest sphere in the top group indicates the current temperature. Galileo Galilei (1564 - 1642) was an Italian physicist, mathematician, astronomer, and philosopher who played a major role in the Scientific Revolution. His findings provided the framework for Newton's laws of motion and Einstein's theory of relativity. 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".

• The Galileo Thermometer is an example of utilizing scientific principle to create a useful artistic piece for day-to-day use. Designed with different colored spheres of varying densities, the thermometer is able to tell the temperature accurately. Decorative functional thermometer is a great conversation piece perfect for the home or office
• Each Galileo Thermometer C&H Solutions is made of hand-blown glass and filled with a fluid in both the cylinder and the floats that is non-toxic, non-hazardous and absolute environmentally safe. It consists of an inert oil-hydrocarbon mixture similar to mineral oil. The cylinder walls material is laboratory grade glass that ensures absolute sturdiness.Sealed glass cylinder contains a clear liquid and several glass spheres of varying densities that individually rise or fall to indicate temperatu
• Temperature range of 18°C (64°F)to 24°C (76°F) t ; each of 4 spheres represents 2°C divisions,Tag on the lowest sphere in the top group indicates the current temperature.Height: 7"/Temperature Accuracy: ±2°C
• As the temperature of the air outside the thermometer changes, so does the temperature of the liquid surrounding the bubbles. As the temperature of the liquid changes, it either expands or contracts, thereby changing its density
• It is not only an enlightenment for curiosity about the science, but also a decorative and funny gift to you and your family. An ideal gift inspiration for Birthday, Christmas Day, Children's day or any time
