Order No. 896.GTB

The Goethe table barometer, also called weather glass or thunder glass, consists of a sphere, which is partly filled with water and has a neck beginning at the underside, which leads laterally upwards and is open to the atmosphere.
When the air pressure rises, the air bubble is compressed in the barometer ball and this changes the water level: it rises in the ball and falls in the neck. Since 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 as accurate as a mechanical barometer, but it is especially beautiful!

Table barometer as glass, height approx. 16 cm, width approx. 9,5 cm
Incl. filling tool, blue colour and detailed instructions
Sturdy foam/cardboard packaging
Note: The Galileo thermometer is made of thin glass. For this reason it is not a toy for children.
