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 features a lovely etching of the Earth's continents. A wooden base makes the set easily displayable on desk or bookshelf. Delightful for gift giving, the unit measures 10.5 inches long and stands 12 inches high.
