According to manufacturer Weems and Plath, there’s a certain amount of mystery surrounding the “how-it-works” question when considering their Storm Glass. This unique, handsome bronze instrument comes filled with a proprietary solution and crystals, which rise up in the glass tube during certain weather events and settle back down during other conditions. While Weems and Plath mention that the “how” could be controlled by electromagnetic changes caused by weather and sun storms, there’s nothing new about this instrument, which was carried by the HMS Beagle (an earlier version, of course) during Admiral Fitzroy’s famous 1750 voyage. $160. www.weems-plath.com
