What you need: medium-sized corrugated pizza box, black construction paper, extra wide aluminum foil, thick sheet of clear plastic, glue, tape, scissors, ruler, magic marker, string, thumbtack, and a dark metal tray.
Sunglasses ,thermometer, and gloves are also helpful. A sheet magnifier may be able to make the oven hotter, and an odor-eater may help take away the pizza smell!
