Order No. 899.FSK

You will not be able to read your future from this “glass ball”, but you will be able to read the future weather. The well-known Fitzroy storm glass is now also available in drop form.

The storm glass, also called camphor glass, was invented before the beginning of the 17th century. It consists of an airtight glass body with a mixture of water, ethanol, camphor, potassium nitrate and ammonium chloride, in which crystals form and dissolve depending on the weather conditions. It was mainly used by sailors to predict weather changes.

The storm glass became famous through Admiral Robert Fitzroy, on whose ship HMS Beagle Charles Darwin travelled with him and made his groundbreaking discoveries. Together with Darwin, he worked out the interpretation of crystal growth during this almost five-year voyage.
The storm glass should allow a forecast over a period of about 24 to 36 hours.
One possible cause for the changes in the crystals is so-called sferic vision, impulsively occurring electromagnetic waves with a long range, which can be traced back, for example, to thunderstorms.
