Yeah, what you didn't see was the craggy old woman floating on the other side of the window. Did you see the way the kid's eyes glowed at the end there?
I don't like this solution. First, how are you supposed to pour ice out of the jug? Second, I challenge anyone to examine two blocks of ice and identify which came from which jug. I suggest that you should pour one jug into the barrel, allow the barrel to freeze, and then pour the second jug's contents in.
