OK... what I did was cut a square in the center of a piece of stiff construction paper. Then I covered the square with a piece of tin foil. Then I punctured the middle of the piece of tin foil with a sewing needle (very small). When I went outside I started out with the pinhole about a foot...
Does intensity of the sun affect this? I keep trying to do it, and when you have a square shape you should still see an image of the sun.. right? Well it is not working! I live in a place with VERY intense sun and no clouds... could this be the problem?
Any help!? Thanks so much...
