A Storm's A' Comin'
Admiral Fitzroy used a device like this to determine weather changes aboard the HMS Beagle on Charles Darwin's expedition. This, of course, is why it’s known as Fitzroy’s Storm Glass. It’s believed that the different crystal formations inside the approx 11” tall x 1-1/2” dia glass tube with a 2-1/4” base indicate weather changes. Must be placed on an interior wall not subject to sudden temperature changes, sunlight or air from vents and may need to be tested in multiple locations. Follow the instructions carefully and give it about a week to stabilize. It goes without saying, but this is not a toy. It has flammable liquid inside, so no rough-housing near the Storm Glass!
