The storm glass became popular thanks to Admiral Robert Fitzroy after his famous trip on the HMS Beagle. Our Teardrop Storm Glass comes with its own stand, making it an awesome gift. No one’s totally sure how it works, but it's thought that changes in the weather’s electromagnetic fields trigger the crystals inside. When the air pressure drops, the sealed glass chamber fills with these cool crystal formations.

It’s a beautiful, unique gift for that hard-to-shop-for adult or anyone who’s into weather and science.
