Mariner's Stormglass

The Mariner’s Stormglass is the Victorian weather technology that's still fascinating today. Its sealed glass tube contains a mixture of chemicals that turns into crystals when a storm is on the way. Based on the designs of sailor and meteorologist Admiral FitzRoy, it’s the same type of device used on Charles Darwin’s voyages aboard the HMS Beagle. Features elegant brass and glass construction. Makes a great gift for nautical buffs and weather watchers alike.
