Tempest Flask

Predict the weather like Admiral Fitzroy and Charles Darwin on the H.M.S. Beagle with the help of this Tempest Flask! While subsequent meteorological science has proven to be a lot more accurate than this elegant glass, the Tempest Flask is certainly the most atmospheric way to know if a gale is imminent or if blue skies await.

But what IS a Tempest Flask?

Also known as a Storm Glass, these sealed glass flasks contain a mixture of distilled water and camphor that form differing patterns of crystalline structures depending on the atmospheric conditions. Early scientists thought that the varying appearances of the crystals could be used to predict the weather!
