My daughter's after school program frequently brings in folks to host science related projects for them. I'm planning to help Zoe build a
pinhole camera and take a few photos with it for her next show-n-tell, and if it goes well, I'll talk to the after-school folks about building
a few more for the kids to use... and materials for the older kids to make their own.

I think a really killer way to promote film would be to have a subscription and/or rent based darkroom setup, maybe base an analog photo club around it.
