Musings from Down Under.
At Co-op we made a solar oven out of recyled material, two boxes, old black plastic, and extra papper scrunched between the boxes to help insulate, Al foil and clear wrap. It cooked a pizza and melted chocolate - not at the same time. The chn and I have saved some materials to make one and D has a external oven thermometer so we can test it and see how hot we can get it. I'll let you know how we succeed or otherwise and send you the details of how we made it, even if it does not work!CheersJxx
