The Fitzroy's Storm Glass is an amazing little thing and a fancy bit of science that will help you to accurately predict the weather to come.

Popularised by Admiral Robert Fitzroy after his historic voyage on the HMS Beagle, you can now forecast the weather too by observing the appearance of the liquid in the glass. When the temperature and pressure of the atmosphere change with different weather patterns, the water and crystals inside the glass change too.

The perfect gift for someone who loves their barometer!

This storm glass is the same size and shape as our 28cm Galileo Thermometers, and they make an attractive pair on the windowsill.
