Package Include: * 1xStorm glass * 1xSolid wood base * 1xInstructions How this storm glass really works is a mystery, but it is believed that electromagnetic changes in weather patterns activate crystals inside (sealed-glass chamber fills with crystals when air pressure decreases). Famed meteorologist Admiral Fitzroy used a storm glass on a historic voyage (1831-1836) with Charles Darwin. A storm glass works on the premise that temperature and pressure affect solubility, sometimes resulting in clear liquid; other times causing precipitants to form. However, the method by which this works is not fully understood. Although it is well-established that temperature affects solubility, some studies have simultaneously observed several different storm glasses forming similar crystal patterns at different temperatures. In addition, sealed glasses are not exposed to atmospheric pressure changes and do not react to the pressure variations associated with weather systems. Snow:The crystalline structures grows like a feather sunny day and summer: The crystalline structures will precipitate to the bottom of the bottle Rain and cloudy days: The crystalline structures will float (change is subtle, not obvious) NOTE: * It can not as precise as weather broadcast, it is mainly used as a beautiful glass artwork with the Simply weather forecast. * Because the indoor Air Conditioner or Heater or constant temperature conditions will affect it changes or no change. * The crystalline structures that form are also very fragile, they will change.but you've gotten the best formations when it's undisturbed
