Boiling water to ice transition on a -20C day in Wisconsin

The mug is filled with tap water heated to a near boiling temperature. The hot water freezes into small particles as they cool from small water droplets (or hot vapor) to ice. This phenomenon is not very well understood. This was taken on a cold Wisconsin day in February, -23C (~ -10F).

The Mpemba effect explains why hot water can freeze faster than cold water, but its not clear if this explains the video entirely.

Why is there no videos on putting boiling water on an iced car

@greg58sean24 You're right, it is >.> Either way I use Celsius because I'm Canadian :x

Very cool, but I am glad it never gets cold enough to try this here in Los Angeles!

@park121998 worked here, -27F, it was awsome

[park121998]

@park121998 but it HAS to be cold enough out side

[park121998]

thats sooooooo cool..... i tried it and it works

[BenBistro004]

Thumbs up if you've tried this and it worked

[superstephen4]

Does anyone know the warmest temperature this can happen at?

[mayonayonayonaise]

YEAH GO WISCONSIN!!! WHOOOO!!!
