That might work. But one of the problems I had was I left the stove running when I filled another bag, and when the bag touched the metal part of the stove it blew open right away. What I'm worried about is that the alumninum foil would also get the same sort of hot spots, which would melt into the bag. But it's worth a try, of course. Work is nagging me this afternoon, so I might not get to it right away if someone else wants to try it.
