Make a solar hot dog cooker

SAFETY FIRST: Ask an adult to help with tools you haven't used before.

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.

    thats easy

  3. At my school we did practically the same thing except we used Pringles cans. THey work just the same and all you have to do is cut a hole in the can add plastic wrap and wait a while.:)

  4. thats cool

  5. this is the best idea I have ever heard

  6. This is a great idea. The solar cooker for a hot dog needs direct sunlight (no shade trees) and the outside temperature needs to be above 94 degrees Farenheit to cook the hotdog in about fifteen minutes or so ( usually with a Heat index of over 107 degrees Farenheit)– about the same temperature as cooking an egg on a cement sidewalk which does not have shade trees around. This is a great idea as a school science fair project. It’s a way to have a hot, cooked meal using absolutely no matches or charcoal.

  7. YEAH!!!!
