I've been kicking around the idea of making small thermal dets which would be fired from my CS-6's grenade launcher. I have the bodies of the dets, vitamin bottles I've been saving for some time now. My problem is that I can't really find anything to glue to the top to give it it's "cone" shape. It needs to be fairly durable so it won't crush or dent if bumped against something as it'll be pretty much visible as it's not carried inside a pouch...Do any of you have any ideas for a relative newbie to prop building? I've thought about styrofoam, but it's fragile unless it's covered in resin or the like-which I've never worked with before. So try and keep any suggestions as "idiot proof" as humanly possible... Thanks!
