I have done this before, and still, it amazes me. We throw boiling hot water into the frosty air, and it turns to snow and damp within seconds.
First, boil water, and put it in a container you can toss stuff from, like a thermos.
Put force into throwing the water out of the thermos as hard as you can.
Voila, looks beautiful! This time it was "only - 11 C " and last time we did it it was - 26, so this time it did not go as well as the first time, but still super nice. Ohh yeah, and the sunrise gives a cool touch to it huh?
Cool in the light before sunrise too :)
