Pringles canisters seem logical candidates for rocketry use. One problem I am having is that the inside coating is super slick. This is great for keeping a smooth surface to slide the parachute out the front, but makes it really hard to attach anything on the inside. I have tried sandpaper and a file to "rough up" the inside (I am using it as a ring fin, so attachments have to be inside.)
Any creative ideas?
