This Solar Oven can heat up small things like marsh mellows. You could easily make S'more. It can easily heat up chocolate. It would be good for a kids science project.
-Cardboard box not a very deep box though
- Clear Tape
Step 1: Cut a Flap Out of the Box
Next you have to cut a flap in the box. All you have to do is make the flap a little smaller than the top of the box.
Step 2: Add the Tin Foil to the Inside of the Box
First you have to add tin foil to the bottom and sides of the box. After that you have to add tin foil to the flap. You only have to add the foil to inside part of the flap.
Step 3: Add Plastic Wrap
Next you have to put your plastic wrap over the hole you made when you cut open the flap
Step 4: Tape It All Together
Just tape the plastic wrap and tin foil down to keep it in place. DO NOT tape the part of the box were you open it or you won't be able to open it.
Step 5: Prop Up the Flap
Make a slit on the edge of the top of the box and angle the ruler to prop the flap. I didn't use a ruler, I used cardboard but it would be better to use a ruler. Also if you want you can put a small paper plat in the oven to put your food on.
