cool.

my guess is because its so cold, and cold air can't hold moisture that it freezes it into crystals. aka a cloud.

It formed a cloud, not gas-phase water (steam). There probably wasn't much water in that pot to begin with. When he tossed it into the air, the water transfered heat to the surrounding air. -50 degree air will have very, very little water dissolved in it, in other words the absolute humidity is very, very low. This boiling water transfered heat into the air, increasing the soluability of water in the air. The water dissolved in the air. As the added heat dissapated into the surrounding air, the water dissolved in the air came back out, condensed, and formed a vapor cloud. All of this happened very, very fast.

Yeah it's just like those guys that go skinny skipping in a frozen pond. It's cold a fvck, but you can stay in there for a few minutes without dying.

sounds right to me.
 
I remember reading in a novel in English class about a hiker in Alaska. He mentioned aomething about at -50 degrees you can spit and it will be frozen by the time it reaches the ground. Can't remember the book, though. :/ I do know that the faster something freezes, the smaller the crystals. But, I would be willing to bet that it was liquid nitrogen that was in that container.
 
I've seen this on the news before, not with a pot of water, but a mug of hot water was thrown in the air on live news coverage and it instantly froze in the air. So its definately possible.
 
Man you can go out in -50C weather its just not reccomended lol

BTW it was -25C here and with the windchill felt like -40C and I went with a shirt and pants to throw out the garbage and trust me, its nothing
 
That's nothing. At some of the family gatherings in Brooklyn, I have seen a pot of hot pasta instantly turn into vapor in the same period of time - perhaps less.
 
I could see it happening, the hot water itself was probably well over boiling, going into that cold 0% humidity weather would turn it into vapor if dispersed into the air properly.
 
I once saw a teacher put an orange in liquid nitrogen for 30 second took it out then tossed on the wall it broke into a million pieces like a light bulb.

I cannot view the video due to network restraints where I am right now. 🙁

However, I will say this is definitely possible. I've seen a pot of boiling water thrown into the air when the temp was minus 72 and it not only turned into a cloud it started snowing! So yes, it could be real.

I'm a snow dog for sure, (I usually wear a sweater when the mercury hits 20 F!) but wearing a t-shirt at fifty below even in calm wind is a little foolhardy.

This thread reminds me to book this. My wife cannot decide if she is going or not but if I can convince her that she will see at least one penguin and polar bear she will. 🙂

Cheers!
