| River City WeatherBall-Rain and Sun-910-100
| Size: 4.5"Wide x 7.75"High
Renaissance scientist's discovered weather was influenced by variations in atmospheric pressure. Torricelli (1608-1647) devised the first barometer, proving that air pressure was subject to change. It is believed that Goethe, the famous German playwright, developed this simple but effective barometer using the principle established by Torricelli.
How does it work?
The WeatherBall quickly indicates any variations in atmospheric pressure. The air trapped by the liquid maintains a steady pressure. When high pressure and good weather are approaching, the liquid is pushed down the spout. When low pressure and bad weather invade your region greater pressure trapped inside the WeatherBall causes the liquid in the spout to rise. Made of hand blown glass and is free standing. Measures approximately 8 inches high,and 5 inches wide at the center. The base is 3 inches wide.
Fun, functional and educational. Attractive for any home or office.
