So easy that four seventh grade girls can make one without a pizza boxThat can bake 1 doger dog(hot dog that is 12in long) Also so that it can roast marshmallows.
Aluminum foil and a clear plastic bowlDig a shallow, curved, round hole slightly less in diameter that the bowlLine the hole smoothly with the foil put the dog a skewer and place it , bridging the holeCover the entire thing with the plastic bowlIt sometimes helps to put a small amount of water on the foil at the bottom of the holeJust enough to form a small poolIt acts like a magnifying glass.
