Solar Oven
What if you have an acute need for homemade cookies while you’re on an adventure, but there’s no oven nearby? Create a solar oven out of a pizza box!
MATERIALS AND PREPARATION
Materials for each solar oven:
• Pizza box
• Scissors or utility knives
• Clear plastic, such as document sleeves or cling film
• Duct tape, masking tape, or scotch tape
• Tinfoil
• Old newspapers
• Black construction paper
• Small aluminum dish
• Skewers
• Rubber bands and small thermometer (optional)
To make:
• Trace a square on the top of the pizza box 2 inches smaller than the box on all sides
• Cut the square on 3 sides: left, right, and bottom; and lightly score the top side.
• On the back of the lid, tape clear plastic to make a window underneath the flap you just cut.
• Cover the inside of the pizza box and the underside of the flap with tin foil.
• Tape black paper to the bottom of the pizza box.
• Roll up old newspaper, cinch with rubber bands, and line all four sides of the pizza box for insulation.
• To operate, place food in an aluminum dish to bake under the plastic window.
• Close the pizza box, and prop open the flap with a skewer.
• Be sure to orient the oven towards the sun!
