Boiling water to snow instantly...

-41c...

Makes the 0c run I am about to go on seem rather tropical.

And that guy's point is that a pan of steaming water turned into snow in about 7 seconds. Or, to put it in another way, Siberia is fucking cold.

My comment was actually sarcastic. I made a new years resolution to be less pedantic, but I just can't help it. I recommend reading up on thermodynamics, as a starting point at least

i think the point is that its underpressure in the air due to low humidity which therefore "absorbs" the water into snow faster than normal. its not really snow either as you see it rises rather than falling down and end up just gone into the air. when its snowy its low altitude pressure compressing the air to then extract its water to fall down on the floor, this is the exact opposite.

It's drunken nonesense chemistry.

At reasonably normal pressures water isn't going to go straight from boiling to snow. Barring some kind've hectic particle accelerator setup (since temperature is after all an average). If people don't understand chemistry there's plenty of videos on khan academy on it on youtube.
