How to Build Your Own Solar Funnel Cooker
What You will Need for the Funnel Cooker:
1. A piece of flat cardboard, about 2 feet wide by 4 feet long.
(The length should be just twice the width. The bigger,
the better.)
2. Ordinary aluminum foil.
3. A glue such as white glue (like Elmer's glue), and water
to mix with it 50-50. Also, a brush to apply the glue to the
cardboard (or a cloth or paper towel will do). Or, some may
wish to use a cheap "spray adhesive" available in spray cans.
You can also use wheat paste.
4. Three wire brads--or small nuts and bolts, or string to hold
the funnel together.
5. For a cooking vessel, I recommend a canning jar ("Ball"
wide-mouth quart jars work fine for me; the rubber ring on
the lid is less likely to melt than for other jars I've found.
A two-quart canning jar is available and works fine for larger
quantities of food, although the cooking is somewhat slower.).
6. The cooking jar (or vessel) should be spray-painted black on
the outside.
