AcuRite Galileo Thermometer with Barometer BallGauge the temperature and air pressure in style with the AcuRite Galileo Thermometer with Barometer Ball. This functional and attractive decoration features a thermometer based on the physicist Galileo Galilei's (1564-1642) discovery that the density of fluid expands and contracts depending on temperature. Five glass spheres feature gold colored medallions imprinted with temperatures ranging from 64°F to 80°F. The density of the liquid in each sphere varies slightly and as the actual room temperature fluctuates, the glass spheres will rise or fall. As the temperature decreases, the spheres will rise and as the temperature increases, the spheres will fall. The lowest floating sphere in the upper group indicates the current temperature. A wooden frame holds the thermometer, joined by a 6.5" barometer ball.
The frosted continents on the barometer ball contrast with the clear glass on the rest of the sphere. Colored water helps define the globe and the water's changing level indicates whether the air pressure is rising or falling. Add water to the globe until the water is approximately 1" up the spout. When the water level is low, air pressure is high and good weather should be expected. If the water level rises in the spout, air pressure is low and the weather is expected to be poor. In severe weather, the water may even run out of the spout. Over time, some evaporation may occur and more water may need to be added. Elegantly forecast the weather from your home with the AcuRite Galileo Thermometer with Barometer Ball. One year limited warranty.
Note: Water is not included in the barometer. You must supply distilled water for accurate readings.
