Réalisation - Parabolic solar cooker

  • Etape 1

    Cover the inside of the umbrella with small strips of aluminium tape.

     

    Pass the strips under the umbrella stretchers from the outer edge towards the inside.

     

    Ensure that the strips overlap slightly in order to obtain a uniformly shiny surface.



  • Etape 2

    Paint the buiscuit box in black, including the bottom (wait until dry).

     

    Secure the box with 4 plastic ties on the central tube (2 fixed end-to-end to extend the length).

     

    Place the box near the center of the tube, where the sun's rays should be concentrated.
