Cardboard and Duct Tape

.....and tin foil and a needle......

....and a piece of black & white photo paper.

And TA-DA, you have your very own pinhole camera. The Cub Scouts came over to learn about photography and we did some hands-on learning. Alas, I forgot to take "before" pictures and "during" pictures, except for this one using my silly camera phone.

The finished product: negative on the left, poorly printed positive on the right (which is why I kept it and not gave it to one of the boys). They each went home with a copy.
