River City Cuckoo 910-102 Swan Shaped Glass Water Barometer

The River City Swan Barometer quickly indicates any changes 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 neck of the swan. When low pressure and bad weather invade your region, greater pressure trapped inside the swan causes the liquid in the neck to rise. If liquid spills into the beak of the swan then prepare for fowl weather! Swan shaped water barometer. Water levels change as barometric pressure changes. Use your choice of food coloring to change the color of the water. Hand-blown glass.- SKU: RCC337
