This Hot Dog Cooker / Solar Oven is simple and easy to make. We have had it reach temperatures over 170 degrees Fahrenheit on a cloudless 80 degree day.


Materials
Pringles can or other cylindrical container.
Sharp knife, make sure you can handle a sharp object or ask for help. Kids - ask a responsible adult for help.
Straight edge, we used a cut piece of aluminum laying around but a ruler would be good.
Sharpie marker or other marking pen.
Skewer
Hot Glue
Drill / Drill Bit

OptionalMaterials
Magnet, Plastic Wrap, Tape


Procedure

Empty contents. Fat Cat had no problem eating the chips in our cans to "help" us out.

Using a straight edge draw a rectangle on the side of the can. We used this side because there were lines already.

Use your knife to cut the rectangle out. Save this piece for later.

Using your skewer, poke a hole through the plastic lid.

Take skewer out and put plastic lid on to bottom of can.

Mark can where hole should go on the bottom of the can.

Drill hole with drill in bottom of can.Put skewer through the lid, the center of can, and the bottom hole


Use the rectangle piece we cut out to make a stand. This will help keep the oven from flipping over.

Take the scrap piece and run a bead of hot glue along the center of the piece. Do not put on the shiny side.

Place the scap piece to the can. Try to make sure that when the solar oven is set down that it will be angled at the sun and not straight up or straight forward. We eyeballed it.

If you want to be exact, use a protractor to determine angle. Different parts of the world get different angles of sunlight and an oven angled properly will get more direct sunlight into the oven causing higher temps.

The stand also allows for different angles. Just rotate the can on its side. Experiment with it and you will see.
