Storm glass or weather forecast bottles are a device invented by navigators in the 17th century to predict weather changes to predict storms. Although this is a great invention, the inventors were not known to the general public at the time.
Later, the equipment became popular in 1860 under the propaganda of the then British Navy Admiral general: Robert FitzRoy (Director of the British Meteorological Agency).
A sealed glass container is filled with a transparent solution of several chemicals. According to changes in external temperature and weather, different types of crystals will appear in the bottleAnd a modern digital humidity / thermometer is given for extra reassurance (XXL version only)
