Keep it very simple for the MSA:
Some cardboard as a lensboard with aluminum foil with a pinhole as a "lens" in the middle.
You can also cut a square out of a cola can, make a pinhole and use some tape as a shutter.
And off course duct tape to put it all together. Shouldn't take more than 30 minutes to put it together.
Instead of 116 film you can use photo paper cut to size as paper sheet film.
The paper negatives can be scanned or just contact printed as well.
I'll promise you: it will be fun and you'll get some astounding images you never expected.
Just give it a try.
