How to Make a Solar Hot Dog Cooker

Harness the awesome power of the sun to cook up a juicy, delicious hot dog.

You will need

  • Cardboard box
  • Utility knife
  • Poster board
  • Scissors
  • Tin foil
  • Tape
  • 2 wood dowels
  • Drill
  • Skewers
  • Hot dogs

Step 1 Select a large box Select a box with a large surface area to make your solar hot dog cooker. A long box will collect more sun rays, which will produce more heat.

Step 2 Cut a parabolic curve Use a utility knife to cut out a parabola that slopes down and back up from one end to the other like the letter “U.” Do this for the two longest, parallel sides.

Step 3 Measure poster board Measure and cut your poster board to fit the curve in the box using a pair of scissors. Cover the poster board with the tin foil, shiny side out.

Step 4 Tape foil poster board in place Tape the foil-covered poster board in place. Find the focal point of your cooker where the heat is greatest using your hand.

Step 5 Measure wood dowels Measure and cut your wood dowels to the right length so they can hold your hot dog at the focal point. Use an electric drill to create a hole in each dowel big enough to hold the skewer.

Step 6 Skewer hot dogs Skewer your hot dog and place the skewer in the wood dowel holes. Plunge the dowels into the ground on either side of the cooker and adjust to find the hottest spot.

Step 7 Wait for the hot dog to cook Wait for the sun to do its job.Give it between 6 and 12 minutes, and you’ll be enjoying your solar cooked hot dog — with or without mustard — in no time.
