Galileo

Weather Station with Hygrometer and Hanging Galileo Thermometer - Cherry-finished Frame - 18 Inches This wall-mounted weather station features two instruments mounted on a cherry-finished wood frame. Instruments included a hygrometer to indicated changes in humidity and a hanging galileo thermometer with multi-colored balls. The galileo thermometer has temperature gradients of 4 F from 64 F to 80 F and is accurate to within 4. Galileo Thermometers are magnificent creations that make Galileo's 400 year old principle of relative density a functional reality. Each Thermometer is encased in brilliant glass with many multi-color floating balls. A gold tag that displays a temperature in Fahrenheit hangs beneath each ball. The Galileo Thermometer is the point at which art meets science. Galileo... Less

A lovely conversation starter and a fun example of early scientific measurement, this Galileo thermometer, Glass Barometer and Analog Hygrometer set from Lily's Home engages the eye while monitoring the weather. Designed for approximate interpretation of temperature and general prediction of fair or foul weather, the set features glass instruments that rely on the principles of buoyancy and air pressure for their function. In the thermometer, the brightly colored internal spheres rise and lower with fluctuations in temperature and corresponding density. The ball-shaped barometer shifts liquid to and from its curved spout in response to changes in the air pressure. The Hygrometer reflects the relative humidity in percent from 0 to 100%. All pieces are beautifully shaped, and the barometer... Less
