Forecast the weather in the traditional manner - of 1750! Admiral FitzRoy, the famous sailor and meteorologist, used the Storm
Glass aboard the HMS Beagle during his historic voyage with Darwin. After 250 years, how the Storm Glass works is still uncertain. The appearance of the crystals inside the glass indicates changes in the weather.
A storm glass is a type of weather-forecasting device, composed of a sealed glass container, filled with liquid, that allows the user to forecast the weather by observing the appearance of the liquid in the glass.
The liquid within the glass is a mixture of several ingredients, most commonly distilled water, ethanol, potassium nitrate, ammonium chloride, and camphor. This specific mixture was developed by Admiral Robert FitzRoy and used on his voyage with Charles Darwin on the HMS Beagle.
Further information on this type of storm glass is found in a set of articles by Sergey P. Fediaev entitled Observation Over Work of the Device "STORM GLASS" (translated from Russian by M. Dvoretskaya, the link is courtesy of the Wayback Machine Internet archive).
