Video: The Eerie Sounds of Skating on Thin Ice

We've all heard the expression "skating on thin ice" before, but this video takes things to the next level. In fact, it literally shows a skater traveling across a frozen lake near Stockholm, while a microphone picks up the eerie – and often scary – sounds that the ice makes beneath him as he goes. The thinner ice actually turns out to be the smoothest, but the nosies it makes is enough to give anyone pause.
