This is a real simple project that is a lot of fun to make and use. It’s especially good for day camp projects or to keep kids busy for the day.
This is the type of cooker shown on Mr. Wizard’s World in the mid-1980’s. I spent many summer afternoons as a kid cooking hot dogs in various solar ovens.
Materials can be found around the house or by scavenging at the campus store… I found the school paper that no one reads to be especially useful.
This is great for hotdogs, grilled cheese, S’mores, etc. Canned soup would be pretty good as well. I think it gets about 225-250 degrees F, though I’ve never put a thermometer in it to find out for sure.
Small box, about the height of the tallest thing you want to put in it. Mine is 8.75 X 6.5 X 5.5 inches
Large box, slightly larger than your small box. Mine is 12 X 9.5 X 5.5″ (basically what they had at the campus grocery store)
Clear plastic wrap (I used a plastic freezer bag. Reynolds oven bags also work well)
Pocket knife or box cutter
Clear tape (optional)
Marking pen (optional)
Cut the flaps off the top of the small box. Line with aluminum foil, making sure to cover all surfaces. You might want to secure it with clear tape, but it’s not necessary.
Seal all the seams on the large and small boxes with duct tape.
Cut out a hole in the top flaps of the large box so the small box just fits. Fill the surrounding area with crumpled newspaper. Tape the flaps down securely with duct tape.
Cover the hole with the plastic wrap and secure with duct tape. Make sure you fasten the duct tape in such a way to facilitate removal later or you won’t be able to put anything in the oven.
Mr. Wizard, eat your heart out.
A box with a lift-off lid (like the kind reams of paper come in) is great for this. The lid lifts off the plastic wrap so you don’t have to worry about replacing it. This is the way I usually make the ovens, but didn’t this time.
Try putting something in the bottom that will absorb heat from the sun, such as black construction paper.
You could probably make one with wood, mirrors, Plexiglas, a rubber seal and heavy-duty insulation. I don’t know how much hotter it would get, but it sure would be cool. If you put handles on it and padlocked it closed you could even leave it secured to something at the trailhead while you were hiking and have hot lunch/dinner when you returned. (I wouldn’t suggest this one in a high traffic area).
Experiment a little and find what works best for you.

I also live in Thailand and I’m making a solar oven from a simple shoebox. I also want to try making one with a pizza box. It seems like a good environmentally friendly way to cook.
