I've scanned tens of thousands of family pictures from negatives to my computer. Now I'm stuck with a suitcase full of negatives and positives. What would be the easiest way to destroy the original film, I don't want to just throw it to trash can and risk that someone can take a possession of them. Cutting them with scissors is not practical due to the large number if film. Burning it may not work as I've heard that film doesn't burn and not sure of how toxic/smelly the fire would be if it did burn. Paper shredder probably also wouldn't work as most of the film is rolled up and I would have to tediously unroll each film and feed it to the shredder. Mabye I could put them all in a large bucket and pour a "chemical" on them - not sure what chemical that would be and how enviromentally safe it would be? Any ideas?
