We prepared following items

  • One sheet of cardboard to make the lid

  • One small roll of aluminum foil.

  • One can of flat-black spray paint

  • white glue

  • One Reynolds Oven Cooking Bag

  • Two cardboard boxes

  • Inner box (18*18*16)inches

  • Outer box (22*22*20)inches




  • Cardboard as a drip pan sunlight to get maximum sunlight and heat

  • Aluminum foil is glued to the cardboard

  • The drip is spray painted black.

  • It serves two purposes:

    painted black to retain heat to heat up the cooking pot, and to hold the pot.




  • Make a lid by folding box

    the four corners of a flat board.

  • Cut three sides of the lid.

  • The opening should be the size of the inner box.

  • Glue the inner side of the lid with aluminum foil. (this will be the primary reflector)


  • Glue the oven cooking bag box

    on the inner part of the lid

    to cover the opening.

  • Now the solar oven is completed and ready to use.


  • Place a digital box

    thermometer

  • (range: -65ºF to 450ºF)

  • Then measured the initial water temperature. (71ºF)

  • Close the lid and kept the oven in the sun making sure the sunlight from reflector reflects directly into the oven.

  • The temperature reaches to 91ºF after 5 minutes.


  • The temperature reached to 122 boxºF five minutes later. (ten minutes after initial reading.)

  • 136ºF three minutes later after the last reading.

    (13 minutes after initial reading.)


  • Five minutes later.. box

    162ºF …

    (18 minutes after initial reading.)

    (We also noticed the water started producing steams)

  • Five more minutes

    173ºF ..

    (23 minutes after initial reading.)


  • Twenty five minutes box

    after the initial reading…

    174ºF…

    (The temperature only

    went up 1ºF in two minutes)

  • Five more minutes later…

    (30 minutes after the initial reading)
