Make a solar hot dog cooker

If you curve some aluminum foil just right, you can cook hot dogs with the sun’s heat.

WHAT YOU’LL NEED

  • Utility knife
  • Tape
  • Saw
  • Drill
  • Roofing nails
  • Glue
  • 2 sheets of corrugated cardboard, 7 1/2 inches by 30 inches
  • 2 2-by-2-by-12-inch connector boards
  • Piece of poster board large enough to cover the bottom of the cooker
  • 12-inch-wide aluminum foil
  • 2 1-by-1-by-13 1/2-inch wood uprights
  • Small wooden dowl, sharpened at one end

WHAT YOU’LL DO

Step 1. Using the utility knife, cut a curve from the two pieces of cardboard.

Step 2. Connect the curves together using the 12-inch connecting boards, glue and roofing nails.

Step 3. Bend the poster board over the curves, mark with a pencil and cut to size. Glue and tape in place.

Step 4. Spread glue evenly onto the poster board. Carefully glue down the aluminum foil. Make it as smooth as possible.

Step 5. Drill a hole in one upright, cut a notch on the other and glue in place.

Step 6. Aim the cooker at the sun, skewer your hot dogs, and get the rolls and mustard.

HOW IT WORKS

The sun reflects heat off the parabolic curve and concentrates it at a single point.
