The Storm Class Cloud is a fun curiosity for the lovers of history, meteorology
or science. Learn to discern the weather forecast with the crystals, stars and
threads that form in this cloud shaped glass on its simple wooden stand.
The Storm Glass Cloud was popularized by Admiral Robert Fitzroy after his historic
voyage with Charles Darwin on the HMS Beagle in 1831.
There are six weather patterns discerned by this nifty invention – the crystals
inside shift and reform based on temperature change and are said to predict
everything from clear skies to snow!
