It's called snowmobile skipping, and apparently it's a thing. The idea is to develop enough speed to hydroplane across the water's surface. The person armed with a camera while doing it here, on Stoney Lake in Ontario, Canada, succeeds brilliantly. That said, YouTube's got plenty of other videos that show what happens when things don't quite work out. Doesn't seem to be nearly as much fun.
Update (10:41 p.m.): The video has been removed from YouTube, so we replaced it with another, slightly less exciting one.
