Use the Barometer Developed by Goethe
- Colorfully displays atmospheric pressure variations
This barometer quickly indicates any variations in atmospheric pressure. When high pressure and good weather are approaching, the liquid is pushed down the spout. However, when low pressure and bad weather are on their way, the greater pressure trapped inside the weatherball causes the liquid in the spout to rise. Size: 7 1/2"H x 4 1/2"W x 4" dia.
