Has anyone thought of using those annoying AOL CD tins for a PSK? It might solve some of the bulk problems and the lid might prove to be a better basis for a reflector than the small mint tins, and the bottom could be used as a cooking plate. <br><br>Also, one idea I've thought of is using a canteen or flask, or perhaps a cook kit as a PSK container. Does anyone know of a flask which can be opened at the widest part and maintain a waterproof seal?
