Goethe Weather Ball Barometer - Multiple Sizes

This device predicts barometric weather changes by observing the rise and fall of liquid within the spout of a vented glass vessel. A low water level in the spout suggests “high pressure”, representing fair weather. A high water level in the spout suggests “low pressure” and forecasts poor weather conditions. While the storm glass will not indicate exact barometric pressure in numerical values, it is still regarded as an accurate monitor of air pressure changes.  PLEASE NOTE: the stated height is only an approximation. This item is finished with a hand process that creates a varying finished height, which may be slightly higher or shorter than the stated height.
