I'm always looking for homemade cooking things so folks can cook when the power is out or unavailable. Several years ago my girls cooked a turkey inside and upside down metal trash can with charcoal in it and on top of it. It worked like a charm. So when I found this card board oven on MacScouter site I was hooked. Living where I do, I know we can go long periods in winter with no sunlight available to use my SunOven.
This cardboard oven is easy to make. You will need a cardboard box and a box knife. Cut the top flaps off so you have 4 sides and a bottom. Now line the inside of the box with foil making sure the shiny side is out. Glue it on to the sides and bottom and fold the bottom edges out and fold down. Here is a picture of the inside of a box oven and they rack they used and pan of charcoal. The charcoal would be on the ground and the rack over it and then the box set down over it.
Blessing to you!
