Weatherball - Swan
Quickly indicates changes in barometric pressure. Hand-blown glass. Fun, Functional, and Educational! Attractive accessory for any home, office, or greenhouse. How does it Work? The Weatherball quickly indicates any changes in atmospheric pressure. The air trapped by the liquid maintains a stead 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. If liquid spills out of the top, you should take shelter!
