1. Place a cardboard box inside a larger box. Choose boxes that will allow for at least an inch of clearance between the two when put together.

2. Fill the gap between the two boxes with shredded paper or fiberglass insulation. This will act as an insulator.

3. Line the inside of the smaller box with black construction paper. You may also paint the inside with a flat black paint. Make certain the paint you use is rated for high heat, such as stove paint.

4. Cut flaps from another piece of cardboard for the reflectors. The piece should be narrow at the bottom yet match the width of the box at the top.

5. Cover the reflectors with foil or another reflective material.

6. Attach the reflectors to the four walls inside the box. This can be done with glue, staples or heavy tape.

7. Prop each reflector at approximately 45 degrees. Once again, you can use glue, tape, staples or even string for this.

8. Place either your black cooking pot or black plate in the middle of the angle reflectors.

9. Cover the box with a piece of acrylic or glass if possible. This will increase the heat retained inside the cooker.

10. Place the entire unit in direct sunlight for the best results.
