International Falls, MN -- You've seen people fry eggs in extreme heat. There's an even cooler trick.
This was the scene in international falls along the U.S. Canadian border.
It was negative 40 degrees Thursday.
In case you can't imagine how cold that is, here's a fun demonstration.
Reporters there decided to see how long it takes for an egg to freeze outdoors at that temperature.
Longer than this story, so we speed up the video and you can see that in about five minutes, an egg is frozen solid.
It's much warmer here now with temperatures expected to reach as high as minus- six degrees.
But forecasters are also calling for a chances of snow beginning Friday.
