This is has nothing to do with the Olympics but is a must-watch. It is equally amazing and creepy. The best parts are about halfway through this piece, when you see the ice surface flexing and then cracking after Marten Ajne skates across it.

I can’t ice skate, so I’ve never been tempting to go out on our lake when it freezes over in the winter. And even if I could, I would always be nervous about how thick the ice is, especially since our lake gets very deep very quickly. No way in hell I’d ever try something like this. But it is fascinating to watch and listen to.
