That's insane.  I can't even conceive of 0 (F, that is), much less -41.

It's cold.

I did this last week, but it was only -30 so it didn't look quite as impressive. PS Bonaventure, I'm starting to suspect you're a closet RT fan.  ;D

Oddly, I can tolerate single digit temps better than say, mid-30's, probably because of the humidity. A rainy 44 to me is worse that a 28*F (like today). I just really hate humidity (I'd never survive in the south).

Hahaha.  I am not surprised.

I'm sure this is old new for anyone who considers themselves a science nerd, but I find it pretty neat!

I think I was absent the day in 4th or 5th grade when we learned why boiling water has a quicker freeze capacity. Why is this?

I haven't studied physics or chem. in a long time, but my guess would be that the molecules are unstable?

Well...it doesn't really.  If you take away the propensity of boiling water to evaporate, then there's much more energy that needs to leave the system before it will freeze - that would be something like a closed container of cold water and one of boiling water put in the freezer.  There's no way that they hot one will freeze more quickly.

In this video, some of the water forms small droplets and a good amount of it vaporizes - all of those tiny collections of water are then quickly frozen.  That doesn't make it any less cool though.

So the same effect would be if the pan of water were measured at, say, 40 degrees Fahrenheit?

No, not if it was thrown into the air like that.  Also, I had to look up what 40 whatevers were in real degrees :(

Boiling water will vaporize and freeze quickly when thrown into the air like that, but not all boiling water will freeze faster (like my example of the closed vessels in a  freezer).  And that's why I grit my teeth when I hear people say you should put warm water in your ice cube trays if you want them frozen faster.  That would only work if a good amount of the water in the trays evaporated and you were left with less water to freeze.

I am sorry. In this inclusive it-is-a-crime-to-high-emotional-feelings world, I impressed my cultural norm on you. I am sorry for not including Centigrade. How intolerant of me. Please forgive me? Is this a forgivable sin?

I snark, I snark!
