We used oatmeal cans, aluminum baking sheets, black trash bags (to help keep light out), photo paper (like what people used to use in dark rooms), tape, black spray paint, and etc. We set up a make-shift darkroom and all the kids had their first ever paper developing experience.
We all learned a lot, including that our pin hole cameras were best at less than three feet away from your subject and exposures were about 10 seconds, instead of the 30 seconds we'd read about. But, we all had fun.
