Specification:Material: Borosilicate Glass, Liquid, Wooden BaseColor: ClearTemperature Range: 18-26 ℃ / 64.4-78.8℉Product Size (H*W): 12X7cm / 4.72''X2.76'' (appr.) Features:- Lowest floating ball represents the temperature.- Attractive ornamental glass thermometer, beautifully crafted and ideal for your home or office.- 5 coloured liquid filled balls marked 18-26 degrees celcius which rise or fall depending on the temperature.- The thermometer is filled with a hydrocarbon which has the ability to change density depending on the temperature, allowing the balls to rise and fall. Working Principle:This thermometer is based on a scientific principal discovered by Galileo. As the liquids in the cylinder contract slightly at higher temperatures, the spheres of slightly different weights rise; as the liquids cool, the spheres drop. The lowest floating sphere in the upper part of the cylinder tells the correct temperature. Warm Tips: The results are for reference only. There is a discrepancy between the temperature shown and the actual temperature. Package Included:
1 x Galileo Thermometer
