Making a solar oven out of tape, a pizza box, and tin foil.
Step 1: A Pizza Box
Now take a pizza box of any kind. A papa johns, a little ceasars, or even a pizza hut.
Step 2: A Square
Now cut a square depending on how you want it on the top of the box. Don't cut it completely off.
Step 3: Tin Foil
Now take tin foil. Now cut a piece of it off about as big as the box.
Step 4: Putting on Tin Foil
Now take the tin foil and put it on the box. You might need a few tin foil pieces. Also put tin foil on the square you cut.
Step 5: You Are Done!!!!
You are now done!! You can now cook stuff in your oven.
