The historic storm glass is regarded as the oldest barometer in the world. Each storm glass is handblown and accurately forecasts changes in the weather hours in advance. Fill the barometer with colored water and watch the rising or falling level of the liquid in the spout to indicate weather changes. A low water level signals “high pressure” and fair weather. A high water level is associated with “low pressure” and poor weather conditions. The barometer shown includes a Chinaberry wood plaque (14"H x 6"W), glass barometer, glass drip cup, syringe for filling and complete instructions and comes finished and ready for gift-giving! The components include a glass barometer, glass drip cup, syringe, and complete instructions.
