I found an interesting tidbit online the other day. Someone had posted instructions on how to make an oven out of an old Pringles can. In the instructions, they used the Pringles can to cook hot dogs. So, I see two benefits to this. First, I get to eat Pringles, and second I get to eat hot dogs. Both are good things in my book. In the end, you just use the heat of the sun to cook your hot dog. Not bad. If you want to see the full set of directions, click the link below.
