How to Build a Pizza Box Solar Oven Follow the steps below to build a solar oven. You may make any modifications to the box once it is builtMaterials: 1 pizza box, newspaper, tape, scissors, black construction paper, clear plastic wrap, aluminum foil, prop. Procedure: 1. Make sure the cardboard is folded into its box shape. 2. Carefully cut out 3 sides of an 8 1/2" by 11" square in the lid of the box. 3. Gently fold the flap back along the uncut edge to form a crease. 4. Wrap the underside (inside) face of this flap with aluminum foil. Tape it so that the foil is held firmly but so that there's not too much tape showing on the foil side of the flap. 5. Open the box and place a piece of black construction paper so it fits the bottom of the box. Tape it by the edges. 6. Roll up some newspaper and fit it around the inside edges of the box. This is insulation. (Materials used to slow the transfer of heat and make things more energy efficient. It should be about 1-11/2" thick. Use tape or other materials you can think of to hold the newspaper in place. 7. Cut plastic wrap an inch larger than the lid opening on the box top. Tape it to the underside of the lid opening. Add another piece of plastic wrap to the top of the lid opening. This creates a layer of air as insulation that keep sheet in the box. BE SURE THE PLASTIC WRAP IS TIGHT. 8. YOU ARE ALMOST DONE! The oven needs to sit at an angle facing the sun directly, so you'll need to make a prop-a dowel, pencil or ruler work great. This way you can change the amount of sunlight striking the oven window.
