This highly functional and decorative “Thunder Glass” barometer predicts weather with atmospheric pressure raising and lowering liquid in the spout. Falling liquid in the spout indicates improving weather; rising liquid indicates worsening weather/precipitation. Fill the glass only halfway with water so the other half is exposed to the atmosphere; be sure to fill on a calm, sunny day. Customize by adding your favorite color to the water. Beautifully crafted filigree cast iron base is ready to be hung on your wall. Hang in partial sun where temperature is fairly constant.
Please note: water can rise very quickly or even spill out into pan when heavy/potentially dangerous precipitation is expected.
