dry ice

Dry Ice when combined with hot tap water can produce vigorous bubbling water and voluminous flowing fog. For example, with 5 pounds of Dry Ice in 4 to 5 gallons of hot water, the greatest amount of fog will be produced the first 5 to 10 minutes. There will be far less fog for the next 5 to 10 minutes as the water cools down and the volume of Dry Ice diminishes. As the water cools, the fog becomes wispier.
干冰在结合了热自来水可以产生积极的冒泡大量流动水和雾。例如，与5磅干冰在4到5加仑的热水，雾最大的金额会产生的第一个5到10分钟。将大大减少在未来5至10分钟的水冷却雾和干冰的量减小。随着水冷却，雾变得wispier。干冰，因为它使低温，-109.3 ° F或-78.5 ° C的热水浸泡，雾，创造了一个真正的水蒸气雾云。当水更加寒冷，超过50 ° F号停止制造干冰雾，但继续升华和气泡。雾将持续较长上比在干燥的天气潮湿的日子。
