Save that last slice of pizza! You can reheat it in its own container, using the sun's power. Turn a pizza box into a solar oven.
You Will Need
* A large pizza box
* A ruler
* A black marker
* A box cutter or utility knife
* Heavy-duty aluminum foil
* All-purpose glue
* Clear plastic wrap
* Black construction paper
* A stick or a hard-plastic straw
* A laser pointer
Maintaining an airtight box is crucial in keeping the oven hot. If you want to test the reflective angles of your oven before you head outside, shine a laser pointer onto the foil flap to simulate rays of sunlight.
