I did this with a piece of disposable pie tin, which I think is somewhere between tin can and tin foil in terms of thickness (very scientific, I know). I made the pinhole with one of my mother-in-law's sewing needles.

As long as you have access to a mother-in-law, you should be able to do the same thing.
