I made a little groove in them to hang containers from. Two liter soda bottles and gallon water jugs are my containers. Works just as well as store bought equipment and didn't cost me a dime. Then we needed something to boil with. As a kid I did it in the kitchen once and my mother kicked me outside. Try boiling 10 gallons down to a quart inside your house and you will see why.

We came up with this
It's an old wood stove we stripped down, and since the stovepipe connected to the side, we could lay it on its side, giving us more surface for the pans. We cut holes into the stove so we could lower the pans into the fire. The pans are two halves of a roaster we bought real cheap.
