HISTORICAL STORY:The device was apparently available in the 18th century and the inventor is unknown. In 1859, violent storms struck the British Isles. In response, the British Crown distributed storm glasses, then known as -- FitzRoy's storm barometers. The storm glass or chemical weather glass was an instrument which was proposed as a method for predicting weather. It consisted of a special liquid placed inside a sealed transparent glass. The state of crystallization within the liquid was believed to be related to the weather. MAIN APPLICATION:how the storm glass would predict the weather: →If the liquid in the glass is clear, the weather will be bright and clear.→If the liquid is cloudy, the weather will be cloudy as well, perhaps with precipitation.→If there are small dots in the liquid, humid or foggy weather can be expected.→A cloudy glass with small stars indicates thunderstorms.→If the liquid contains small stars on sunny winter days, then snow is coming.→If there are large flakes throughout the liquid, it will be overcast in temperate seasons or snowy in the winter.→If there are crystals at the bottom, this indicates frost.→If there are threads near the top, it will be windy. In Fact, “Temperature change is the sole cause of crystal growth in storm glasses. ” MORE KNOW-HOW:Q1:What is the material of this storm bottle?
