1. Measure an inch from each edge of the pizza box and mark with a pencil. Draw a square on the pizza box using those measurements. Cut three sides of the drawn square to create a flap. Wrap the inner side of the flap with aluminum foil and secure it in place by taping it to the back of the flap.

2. Open the box and secure two layers of plastic wrap over the opening you just cut in order to create an airtight window. Use enough plastic wrap so that it can be secured tightly to the pizza box lid with tape. Tape the plastic wrap to the box.

3. Line the inner bottom of the pizza box (where the pizza would lay) with black construction paper and secure it with tape.

4. Roll up four tubes of newspaper (each 2-3 inches thick) and tape each one so that they do not unroll. Place each tube inside the pizza box along one side (top, bottom, and two sides) so that they serve as insulation. Secure each one to a side of the pizza box with tape.

5. Find a sunny place outside to position your solar oven. The best time to cook your food is when the sun is directly overhead, between 11 am and 3 pm.

6. Place your food item on a plate inside your solar oven and close the lid. Lift the flap and angle it so that it receives a lot of sunlight that it can reflect onto the plastic-wrapped window. Prop it up using a ruler, wooden spoon, or stick.

7. Place a thermometer inside the oven to check the temperature later. Most meats need to reach an internal temperature between 145-165º F (about 63-74º C) in order to be safe to eat. When the food is cooked sufficiently, use oven mitts or potholders to remove it.
