I would never think to take a chainsaw and cut a huge circle in the middle of a lake in hopes of making a carousel. 

That's exactly what two guys from Arenac County did during the holidays. According to WNEM,  they got the idea from a YouTube video. They spent two and a half hours bringing the ice carousel to life in the community of Omer. In the video above they explain exactly how they did it and how they were able to make it spin like a carousel.
