Today I found the coolest video that shows what happens to boiling water when it is pitched into the air in arctic temperatures. It makes INSTANT snow. Cooler yet is the science behind it: hot water is easier to freeze than cold water. How’s that for defying logic?
According to Mike Krumboltz, writing for Yahoo’s quasi-news segment “The Sideshow:”
The man boiled water and then tossed it over the balcony of his apartment. Normally, that sort of thing would get you arrested. But in arctic-like temperatures, the result is quite beautiful. As soon as the man tosses his pot of boiling water into the freezing air, it turns to snow and leaves behind a trail of mist across the sky.
If you paid attention in high school chemistry, you might remember that boiling water freezes faster than cold water. Known as the mpemba effect, the phenomenon remains a mystery to many. Not even scientists can agree why hot water tends to freeze quicker.
I envision a bad guy on a high balcony trying to hurt the hero standing below in the snow. The fiend pitches boiling water at the man below him. The hero cringes, bracing for a scalding, then laughs and bounds through the snow veil into the building to apprehend the crook. What do you see?
