Group size: Adaptable, Big group 10+, small group 3+ and medium 5-9
Timescale: 1-2hrs
Where?: Outdoors

What you need Pizza box. The larger the box the better the oven should work.
Pencil or pen
Ruler
PVA glue
A sheet of black paper
Utility knife
Aluminium foil
Plastic wrap/ cling film
Shipping tape or black electrical tape
A wooden skewer or pencil

Instructions:  On the top of the pizza box's lid draw a square that is about one inch inward from each edge.
cut along each side of the square you just drew except the side that runs along the hinge of the box. Cut all the way through the cardboard on those three sides of the square. Then fold the flap back slightly along the attached side.
Line the inside of the cardboard flap with aluminium foil. Fold the edges of the foil over the flap to help hold the foil in place and glue the foil onto the flap. Keep the foil as smooth as possible.
Cover the opening made by the flap (in the lid) with a layer of plastic wrap. Attach the plastic wrap to the opening's edges using shipping tape or black electrical tape. Make sure there are no holes in the plastic wrap and that all of its edges are completely attached to the lid.
Line the inside of the box with aluminium foil so that when you shut the box the entire interior is coated with foil. It is easiest to do this by covering the bottom of the box with foil and then covering the inside part of the lid (going around the plastic-covered opening) with foil too. Glue the foil in place.
Glue or tape a sheet of black paper to the bottom of the box centred there.
Lastly use a wooden skewer or pencil (and some tape) to prop the solar oven's lid up at about a 90-degree angle from the rest of the box.
