I was shown a neat trick with a Dymo labeling tape. Those are those label makers that people use to put a label on a tool box or drawer that says 'screwdrivers' or some such. You peel off the sticky tape on the plastic label and insert it in the film canister. Wind the film a little until you see it pulling the Dymo label into the canister. You know now that it is sticking. Then pull out the Dymo tape and out will come the film. Nothing to it. I have done it several times. Or you can buy a $7.00 retreival tool. I prefer the 1 cent piece of tape.
