The water in the air trick, pfff, it's boiled water, and it vaporizes quickly because of that. Every year the lapps up north pull that shit, and they air it on the news down in Italy or wherever. Lemme know when your snot freezes on each inhalation, then we'll talk about cold!
Still though, -40 is some serious cold, gotta give creds for that. But northern Norway *still* beats that! Under "ideal" conditions, you can experience -60C
