1. Cut out a piece of aluminium from a beer can and flatten it out.
2. Using a ball point pen, make a small dent in the middle of the piece of
aluminium.
3. With a piece of sand paper, gently rub down the protusion on the back of
the aluminium caused by the dent, until there is just a very thin layer of
metal left. Be very careful not to rub it all the way through.
4. Place the aluminium on a flat, hard surface and carefully push the head
of a needle through the thin part of the metal, making sure that only the
point of the needle passes through.
5. Turn the aluminium over, place the head of the needle through the back
of the hole and twist it gently to get rid of any imperfectins  in the tiny
hole. You now have your pinhole.
6. Drill a hole measuring 5-6mm across in the center of a plastic body cap.
7. Tape the piece of aluminium with the pinhole in it over the hole in the
body cap and put the cap on your camera body. You now have a pinhole camera
and are ready to take pictures.
