Step 1: ​Draw a Square

Using the ruler and black marker, draw a square on your pizza-box lid, leaving a 1-inch border from the edge of the box to each side of the square.

Step 2: Form the Flap

With the box cutter or utility knife, cut through three sides of the square you just drew, leaving the line at the rear of the box attached. Fold the flap back so that it stands up when the pizza-box lid is closed.

Step 3: Step 3: Cover the Flap With Foil

Cover the underside of the flap and the inside of the box with heavy-duty aluminum foil, which will reflect sunlight into the oven. Glue the foil to the flap, smooth out wrinkles, and cut off any excess.

Step 4: Black Construction Paper

Glue black construction paper onto the bottom of the foil. This will keep light from reflecting out of the box.

Step 5: Foil Insulation

Roll up 6 foil strips 5 inches long. Glue those strips to the walls of the pizza box.

Step 6: Tape Plastic Sheet

With the scissors, cut two square pieces of clear plastic wrap, each 1 square inch larger than the flap opening. Open the pizza box, and tape one piece of plastic to the underside of the hole so that the plastic covers it.

Step 7: Tape Second Plastic Sheet

Close the lid, and tape the second plastic sheet over the top of the hole, creating a window that helps keep the sun’s heat in the box. Pull both sheets taut as you tape them.

IMPORTANT: Make sure the box is airtight because it will keep the oven hot

Step 8: Construction Paper

Cover the foil layer in the box with sheets of black construction paper and glue them into place. The black base will absorb light and generate more heat inside your oven.
