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 aspect of the square.

Step 2: Type the flap
With the box cutter or utility knife, minimize by way of 3 sides of the square you just drew, leaving the line at the rear of the box hooked up. Fold the flap back again so that it stands up when the pizza-box lid is shut.

Step 3: Cover the flap with foil
Cover the underside of the flap with significant-obligation aluminum foil, which will replicate daylight into the oven. Glue the foil to the flap, sleek out wrinkles, and minimize off any excessive.

Step four: Tape plastic sheet
With the scissors, minimize two square parts of apparent plastic wrap, each 1 square inch more substantial than the flap opening. Open the pizza box, and tape just one piece of plastic to the underside of the gap so that the plastic addresses it.

Step 5: Tape second plastic sheet
Shut the lid, and tape the second plastic sheet about the top of the gap, building a window that helps preserve the sun’s heat in the box. Pull both of those sheets taut as you tape them.

Adjust the foil flap to find the very best ray-reflecting angle, and use the ruler, a adhere, or a really hard-plastic straw to preserve the flap propped in place.

Tip
If you want to take a look at the reflective angles of your oven right before you head outside, shine a laser pointer on to the foil flap to simulate rays of daylight.

Step nine: Preheat
Preheat your oven by leaving it in direct daylight for 30 minutes. The box’s temperature will reach about two hundred levels, so when you won’t be in a position to cook dinner a roast, you can reheat cooked food items, melt cheese or chocolate, or—if you have all day—prepare a veggie stew.

Step 10: Cook
Regardless of what you determine to cook dinner, place it—on its personal, or in a heat-safe container—in the heart of the oven, so that it is straight less than the plastic-wrap window. Shut the lid, leaving the flap propped open, and examine on your food items each individual 15 to 30 minutes.
