The storm glass was popularised by Admiral Robert Fitzroy after his historic voyage on the HMS Beagle. This storm glass is the same size and shape as our 28cm Galileo Thermometers, and they make an attractive pair on the windowsill.
How the Storm Glass works is still a mystery, but it is believed that electromagnetic changes in weather patterns activate the crystals inside (sealed glass chamber fill with crystals when air pressure decreases).
This is a gorgeous decorative gift idea for the adult who has everything or someone who finds meteorology fascinating.
