Super-Easy Solar Tea Wash a one gallon glass jar and its cover. Fill with clean
water. Drop 6-8 regular tea bags into
the jar, hanging the strings out the top. Put the cover on the jar. Place
the jar in a sunny place.
Let stand for 2-4 hours. Your tea will be warm, but not hot. Chill or
serve over ice for solar iced tea!
1. Get a corrugated cardboard pizza box.
With help from an adult, cut the top to make a reflector flap.
Cut 3 sides, 1 inch from the top edges. Do not cut the 4th side.
It will be your folded "hinge".
2. Glue aluminum foil (shiny side up) to the inside of the reflector
flap. Be sure to wipe off any extra glue to keep the foil shiny.
Tape plastic to the inside of the box lid, over the opening. Make
sure that you seal all the plastic edges well with the tape. The
window will keep the heat in the box.
3. Glue black construction paper to the insides of the box. Leave
your plastic window uncovered.
You can decorate the outside of
your box if you would like. Remember--the box should absorb light from the
sun. Dark colors absorb light rays and light colors reflect light rays.
(I painted the outside of my box with black paint.)
Now set up your box in the sun. You need to have the
reflector flap face toward the sun.
(I put my box on a piece of black poster board)
When I set my box up at noontime in July, the sun's position
was so high overhead that I needed to tilt my box up for the reflector
to work. I made my tilting platform by folding a 12 inch by 48 inch piece
of cardboard into a triangle shape. I held it together with a spring binder
clip. You can also use clothes pins. Using these instead of tape lets
you adjust the triangle if you need to.
Now you are ready to cook!
Chocolate ( miniatures or broken candy bar pieces)
1. Break a long graham cracker
in half to make a square.
2. Put a piece of chocolate
on top of the cracker.
3. Put a marshmallow on top
of the chocolate.
4. Place this stack
in your solar pizza box oven. Heat for 30 minutes to 1 hour. Do not open
the box until you
are ready to take your food out. Just like the home oven, when you open
the door, all the heat
Be careful if you have to tip
your oven with the triangle base. The marshmallows fall off!
If you put a sheet of black construction paper in the oven for a "plate",
it will help to keep your oven cleaner.
The temperature of the pizza box oven is not hot enough
to cook food! Use this oven only to warm foods which have already been
cooked. Use safe food handling practices. See the World Health Golden
