The Fitzroy Barometer is an elegant and spectacular gadget that allows you to easily observe changes in the weather. It works thanks to chemical reactions in a special solution - when air pressure rises, the liquid rises, and when it falls, it drops. Thanks to this, the barometer \"predicts\" the weather: it indicates whether sunny days, rain, or storms are approaching. It is a fascinating combination of science and design - perfect for those who appreciate practical yet striking accessories. USED IN THE 1750S Such unusual barometers were already being used in the 1750s. Charles Darwin used a Storm Barometer to forecast weather on his ship, including during his famous scientific expedition to the Galapagos Islands. CHANGES SHAPE DEPENDING ON THE WEATHER Inside is a mixture of distilled water, ethanol, potassium nitrate, ammonium chloride, and camphor. Camphor is the key! Depending on atmospheric conditions - mainly changes in pressure, temperature, and humidity - unique crystals form, dissolve, or change shape in the solution. The liquid is crystal clear: Sunny and dry weather is likely expected. Tiny, cloudy stars or flakes appear in the solution: This indicates approaching cloudiness, fog, or rain. Large, feathery crystals: Signal an approaching storm or heavy rain. Filaments or threads of crystals form at the top of the liquid: Indicates windy weather. Product Information: Product: Storm Glass (Fitzroy Barometer) Shape: Teardrop Container material: Glass Height: 11 cm Liquid composition: Water, ethanol, natural camphor, and other ingredients (e.g., ammonium chloride, potassium nitrate) Working principle: Change in the appearance of crystals depending on ambient temperature and atmospheric pressure.
