有位叫凯琳·尼科尔的网友发推写道:“我试图将开水泼洒到空中,但它落回来了……所有的开水都洒在我身上,现在我的腿被烫伤了。哎哟……”
Hallie Benjamin added: 'So I tried to do the whole throw boiling water outside and it flew back and burned my arm so happy snow day to all.'
另一位叫哈利·本杰明的网友则表示:“告诉大家,我尝试把整壶热水洒向室外空中,然后它就洒落回来了。然后我的胳膊就烫伤了,这真是个‘欢乐’的雪天。”
One person who got it right was meteorologist Eric Holthaus. He conducted his experiment on January 6 in Viroqua, Wisconsin where the temperature was a chilly -21F with a wind chill of -51F.
气象学家埃里克的操作方法是正确的。他于1月6日在威斯康星州的韦罗奎进行了这项实验,当时气温低达华氏零下21度(约为-29℃),局部寒风地区低达华氏零下51度(约为-46℃)。
He threw his pan of hot water high into the air, being careful to make sure it blew away from him, before it turned into a beautiful, crystal cloud.
他在确保水不落回自己身上之后,把一壶开水泼到空中,随后开水就变成了漂亮如水晶般的雪云。
Boiling water turns into snow because freezing cold air holds less vapor than warmer air.
冷空气比暖空气的水蒸气含量少,所以开水会变成雪花。
