When it gets really cold, people get bored. Some decide to experiment with boiling water in icy conditions, just to see what happens. This was tried first in conditions of -30°C in Yellowknife, Northwest Territories in Canada, and then in -41°С Russia
The girl in the video above boils the water, and throws it into the air where it "evaporates" and turns into an icy fog.
Some Russians caught the video on YouTube, and decided to do the same experiment, but in temperatures of -41°С, from the balcony of an apartment building. Again, the cloud of fog hangs in the sky, but the impression is given that this cloud is frozen!
According to Physlink.com, the water freezes in mid air creating a shower of ice crystals. Because the hot water is so close to being steam, the act of throwing it into the air causes it to break up into tiny droplets. The cooled droplets are so small, that they can be easily frozen by the winter air. All of this happens before the water hits the ground.
The Russians comment under their video, the equivalent of "Don't try this at home!"
