You will need the
following: cardboard boxes, scissors, ruler, pencil, extra wide aluminum
foil, two 35 cm long wooden sticks, two 29 cm long wooden sticks, scotch
tape, glue, 15 cm wire and a 50 cm string.
(note images
are not shown to scale)
Cut open the cardboard boxes, as shown.
Cut twelve pieces of cardboard 24 cm x 61 cm.
Draw the following figure on each of the 24 x
61 cm pieces of cardboard.
(measurements image borrowed from
www.solarcooking.org)
Cut out twelve copies as shown below.
Make sure you fold each one on the "fold lines"
as shown on measurements image.
Make the holes shown very close to the fold
lines.
Tape the 12 pieces of cardboard together along
the long sides.
You should now have something similar to the
image shown below.
If you join the ends of the cooker you will
obtain a figure like the one shown below. Do
not tape them together yet, since we must first
glue on the aluminum foil.
Glue on the aluminum foil only on the inner
side of the cooker. Try to make the surface as
smooth as possible.
Your cooker should now look something like the
one shown below.
Join the ends of the cooker and tape them
together. Pass the string through the holes
on the top of the cooker and tie it together.
Cut a circle 15 cm in diameter and glue foil on
one of its sides.
Cover the hole on the cooker with this piece
and tape it.
Your cooker should now look something like
this..
Make 4 holes on the inside of the cooker as
shown below.
\Insert the 35 cm wooden sticks into these
holes. Tape them on the back of the cooker to
hold them firmly.
Place the 29 cm wooden sticks as shown in the
figure below. Tie them to the 35 cm
sticks using a thin wire.
And the cooker is finally ready. If everything
went ok your cooker should look like the one shown below. The wooden
section will be used to hole the pot.
You should use a black pot for cooking for
better results. Do not use pots with an
aluminum outer surface since they will not
absorb the heat.
Hope you have a good time cooking!
