Fitzroy Storm Glass (11" Tall)

Product Review

Barometer height: 5.9 inches
Low level of liquid in spout = high pressure and fair weather
High level of liquid in the spout = bad weather

The concept that decreasing atmospheric pressure predicts stormy weather was postulated by Lucien Vidie -- and it's the basis for a weather prediction device called a storm glass or liquid barometer.
A narrow spout connects to the body below the water level and rises above the water level, where it is open to the atmosphere.
Includes limited 2 year factory warranty.
Includes glass drip cup to avoid staining. Clear glass bulb with world map etching.
Note: You can vary the water color by adding food coloring of your choice. The image above is shown in blue.
