Desktop Teardrop Fitzroy Storm Glass

Enjoy predicting future storms with this attractive Desktop Teardrop Fitzroy Storm Glass. It's named after Admiral Fitzroy, an accomplished meteorologist who used a storm glass on his historic 1831 voyage with Charles Darwin aboard the HMS Beagle. Suspended in a square-shaped, black wood frame is a clear glass teardrop. How this storm glass actually works remains a mystery, but theories show electromagnetic changes in weather patterns activate the crystals inside the teardrop. When the air pressure decreases watch and wait as the glass chamber fills with white crystals. Predictions are usually 1-2 days in advance. An unusual accent for any home or office, don't be surprised if this tabletop storm glass catches the attention of guests and visitors. It also makes a unique gift for any at-home meteorologist. Size: 4"W x 2"D x 5¾"H.
