The next step up is the box in a box with a reflector flap
and a clear window. This cooker just
sounds complicated but since it uses glue and aluminum foil, cardboard boxes
and a little spray paint, it is just kindergarten art on steroids!

First, paint the inside of the smaller box and your small
piece of cardboard black, and check your pots, if they need painting, do that
now and let it all dry. Place small box
on top of closed big box and trace the box onto the lid, set aside. Cut away the rectangle made by the
tracing. Open the box and glue aluminum
to all the sides, inside. This is a good
time to practice lining. This first box
won’t look great, but you will get better and no one will see this part. Fold down the remainder of the top flaps and
glue in place. You may need to use a
clothes pin to clamp the flaps till the glue dries.
Now that you are good at lining, fold the flaps down and
line the entire inside of the small box with foil. Make it smooth and keep the glue off the
surface. Place the small black painted
cardboard into the small box as a drip pan.
You now have the insulator and the oven complete.
Next, make the removable lid/ reflector/ glazed frame. Lay the large piece of cardboard down on the
ground; trace the large bow onto it leaving a two to three inch border. Place the small box on the same piece of
cardboard and WITH the ridges running side to side, trace the small box onto
the cardboard. Set aside boxes. The flaps are made by cutting from the
outside edge to the mark of the big box, fold and overlap the corners and
staple them or glue and clamp until dry.
This creates a removable lid for the cooker. Now, make sure ridges of cardboard are
running side to side and cut a flap by only cutting along the two sides and
front of the cardboard. This creates the
flap. Line the inside of the flap with
foil. This creates the reflector. Turn the piece over and glue a glazing
material to the inside.
The glazing material can be plexiglass or the glass from an
old picture frame or an oven roasting bag (turkey size. Glue open end shut then glue to lid frame).
To finish, crumple news paper to keep the small box off the
big box, about an inch off the bottom.
Place pots of food in small box.
Put lid on box and lift flap.
Prop flap up with pencil or dowel.
TAA DAA!
