ES-308 Weather Globe Desktop Storm Glass Barometer

Indicates changes in air pressure quickly and accurately. The ball is filled with colored distilled water. Once filled the air trapped inside the ball is no longer subject to variations in atmospheric pressure. The liquid in the indicator tube, however, remains open to the atmosphere and is directly affected by atmospheric pressure. When atmospheric pressure rises, the liquid in the indicator tube is pushed down and an improvement in the weather can be anticipated. When air pressure falls, the greater pressure inside the ball causes the liquid in the indicator tube to rise, indicating that a deterioration in weather (storm) can be expected.
Sizes available for selection ( height ): 10cm, 13cm, 15cm, 17cm, 20cm, 25cm
Color choices of liquid: red, blue, green
