Draw a square on top of the pizza box that's about 1-2" smaller than the box itself. Use the box cutters to cut along the line, on the right, left and bottom of the box, creating a flap that open upward.
Cover the underside of the flap and the inside of the box with foil, shiny side out. Try and keep it as smooth as possible! Glue it down so it doesn't fall off.
Inlay the box with the black construction paper, gluing it to the bottom so it stays put
Tape the clear sheet protectors to the lid of the box to seal the opening created by the flap. The seal should be as airtight as possible!
Place your oven outdoors in direct sunlight on a hot day. Assemble your S'mores and have a thermometer nearby if you can!
Close the lid of the box and prop the flap open with a stick. Leave your S'mores to "cook" for about 30 minutes. Depending on how airtight your oven is, you could see temperatures around 200 degrees!
Enjoy your chocolaty- marshmallow creation! The messier they are, the better they taste, right?!
