how to make a pizza box solar oven

What you'll need:
- a pizza box
- black construction paper
- aluminium foil
- clear plastic or plastic wrap
- non-toxic glue and tape
- wooden skewers

What to do:
Draw a 2.5cm border on all 4 sides of the top of the pizza box.


Cut along 3 sides leaving the line along the back of the box uncut.


Form a flap by gently folding back along the uncut line to form a crease.


Cut a piece of aluminium foil to fit on the inside of the flap. Smoothe out and wrinkles and tape into place.


Measure a piece of plastic to fit over the opening created by forming the flap. Be sure the plastic becomes a tightly sealed window so that the air cannot escape and tape firmly in place.


Cut another piece of aluminium foil to line the bottom of the box and glue into place.


Cover the foil with a piece of black construction paper and tape into place.


Close the pizza box top and prop open the reflective foil flap of the box with the wooden skewers.

And now your solar oven is ready to use!
