Baby, it's cold outside. And to prove it, we offer up this video shot by a man in Siberia in -41 degrees Celsius weather.
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.
Don't try this at home, but check out the clip above.
