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!



Food coloring is not included. This barometer is made with hand-blown glass and is covered by a two year limited warranty covering workmanship and manufacturers defects.
