Fitzroy's Storm Glass Teardrop shape

The storm glass was popularised by Admiral Robert Fitzroy after his historic voyage on the HMS Beagle. The Teardrop Storm Glass comes with a stand, making it a wonderful gift.

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.
