Depending on the day's weather, the mountain hut might appear clear or shrouded in morning mist. This storm glass makes it fun to peek at the weather in the morning. A storm glass is a weather forecasting tool used by sailors in 19th-century Europe. Storm glasses, which change appearance depending on the weather, are popular as stylish interior objects. Inside the glass is a liquid that dissolves chemicals such as camphor, potassium nitrate, and ethanol, but the detailed relationship between crystallization and the weather is still not fully understood. Although not scientifically proven, the appearance of the liquid inside the glass changes daily depending on temperature and humidity. Weather forecasts are possible, such as "clear" when crystals settle at the bottom and the liquid is clear, "rain" when small crystals are suspended, "snow" when the entire glass turns white, and "storm" when the crystals are coarse and not transparent. (※ The appearance of the crystals is only a guide. In reality, there are individual differences depending on the installation location and other detailed conditions.)
