It's not film, it's the paper would project the negative onto to make a picture using an enlarger. It's not as readily available in this digital age but you should still be able to find it at a "good" camera store. I'd look for maybe single owner dedicated to craft type places vs chain dedicated to tech. You'll be wanting the B&W stuff, easier to develop and you can work with it under red lights instead total darkness. You'll also need 2 chemicals called "developer" and "fixer" suitable to the paper and distilled water to bath it in. Pinhole cameras are fun because you can build them in less then an hour for nearly free and it gets you hands on with the underlying principles of photography.
