The Goethe table barometer, also known as a weather glass or thunder glass, consists of a sphere that is partially filled with water and has a neck starting at the bottom that extends upwards to the side and is open to the atmosphere.
When the air pressure rises, the air bubble in the barometer ball is compressed, which changes the water level: it rises in the ball and falls in the neck. As there is relatively little water in the neck, the rise and fall of the water level is particularly noticeable here.
This air pressure gauge is not quite as accurate as a mechanical barometer, but it is particularly beautiful!
Features:
- Glass table barometer
- Height approx. 16 cm, width approx. 9.5 cm
