The Fitzroy Barometer is an elegant and spectacular device that allows for easy observation of weather changes. It works thanks to chemical reactions in a special solution – when atmospheric pressure rises, the fluid 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. IN USE SINCE THE 1750S Such unusual barometers were already in use as early as the 1750s. Charles Darwin used the Storm Barometer to forecast weather on his ship, including during his famous scientific expedition to the Galapagos Islands. SHAPE CHANGE DEPENDING ON THE WEATHER Inside, there 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 their shape in the solution. The liquid is crystal clear: It will likely be sunny and dry weather. Small, cloudy stars or flakes appear in the solution: This indicates approaching cloudiness, fog, or rain. Large, feathery crystals: Indicate storms or heavy rain. The crystals form threads or filaments at the top of the liquid: Indicate windy weather. WHY IT IS WORTH IT Elegant Frame: The minimalist, black MDF frame perfectly highlights the glass teardrop, giving the whole piece a modern and sophisticated character. Visual Weather Forecasting: Observing the changes in crystal form (cloudy, clear, feathery) is an intuitive and fascinating way to predict weather changes. Decorative Element: The sturdy frame and aesthetic shape make this barometer ideal for a study, office, or living room, increasing their prestige. Durable Craftsmanship: The glass is securely fastened in the MDF frame, protecting the delicate vessel and providing stability on a desk or shelf. Original Gadget: This is a replica of a device used for predicting storms, making it an interesting and meaningful accessory for lovers of history and science. Product Information: Shape: Teardrop Vessel Material: Glass Frame\/Base Material: MDF board (black color) Height: 14 cm Liquid Composition: Water, ethanol, natural camphor, and other ingredients (e.g., ammonium chloride, potassium nitrate) Working Principle: The change in the appearance of crystals depending on ambient temperature and atmospheric pressure. Application: Weather forecasting, desk\/shelf decoration PERFECT GIFT: For an Amateur Meteorologist: A fantastic, visual tool for observing weather, complementing traditional thermometers and barometers. Desk\/Office Decoration: A minimalist glass decoration that adds elegance and is a conversation starter. For a Teacher\/Scientist: An ideal, exciting gift with scientific heritage, explaining the phenomenon of crystallization. For Those Who Appreciate Peace: Observing the slow changes occurring inside the vessel is relaxing and soothing. For Sailing Enthusiasts\/Travelers: Historically linked to sea voyages, a symbol of adventure and traditional navigation. NOT JUST AN INDICATOR, BUT ALSO A DECORATION The Fitzroy Barometer is an ideal object for everyone. It is a unique, charming gadget that combines historical interest with decorative elements. It is a striking ornament and an exciting conversation topic for any living room, study, or office. HOW THE FITZROY BAROMETER WORKS: The Fitzroy Barometer, also known as a Storm Glass or Storm Crystal, is a historical meteorological instrument popularized by Vice-Admiral Robert FitzRoy, captain of the HMS Beagle (the ship on which Charles Darwin made his famous voyage). FitzRoy used and perfected this device for predicting sea weather, publishing detailed instructions for its use. The key component of the barometer is camphor, an organic terpene compound, and its accompanying salts: potassium nitrate and ammonium chloride, dissolved in a mixture of ethanol and distilled water. The solution is hermetically sealed, but it does not function like a typical atmospheric pressure-measuring barometer.\u003c\/p\u003e","brand":"GiftDeco","offers":[{"title":"Default Title","offer_id":52545708884304,"sku":"323289","price":12990.0,"currency_code":"HUF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0568\/1466\/5925\/files\/Img_ab36ec29-f600-49cf-8761-fb569a3b2dc2.jpg?v=1768076062","url":"https:\/\/modianoajandek.hu\/en\/products\/fitzroy-viharbarometer-fa-keretben-csepp-viharuveg","provider":"MODIANO","version":"1.0","type":"link"}
