Nauticalia Admiral Fitzroy 19th Century Glass Storm Predictor Bottle

  • Aboard HMS Beagle during the Darwin Expeditions of 1831-36, Captain Robert Fitzroy developed and refined the 18th century storm bottle..
  • This involved much testing and observation and resulted in him being able to make a number of weather predictions with a fair(ish) degree of accuracy. The point is that then, as now, no one is quite sure how the storm bottle works..
  • Is it atmospheric pressure? Temperature? Electrical disturbances? And it’s this element of uncertainty, of almost magical alchemy, that makes these storm bottles so fascinating. Stands 16cm high on a traditional wooden base and comes with Fitzroy’s observations. Will you agree with them or find new interpretations?.
  • The mystery’s been going on for nearly 180 years. And looks set to continue..
  • Changes in the crystals that form inside this fascinating, mysterious, little instrument can be used to predict even quite subtle changes in the weather.
