Ambient Weather B1025C Antique Storm Glass Wall Mount Liquid Barometer with Drip Cup

This traditional weather station is both a work of art and an instrument at home in any fine study, library, office or upscale restaurant. The classic weather station measures barometric pressure (liquid). The antique weather station displays an air of quality and accuracy one would expect with a fine, handcrafted weather instrument from Ambient 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. It consists of a glass container with a sealed body, half filled with water. A narrow spout connects to the body below the water level and rises above the water level, where it is open to the atmosphere. When the air pressure is lower than it was at the time the body was sealed, the water level in the spout will rise above the water level in the body and when the air pressure is higher, the water level in the spout will drop below the water level in the body.
