If this is improved a little, ie. better material, etc. it might make a great substitute for the Titan rocket. It might also have to be made a little bit longer .
If you want a another alternative to a knife or lighter fluid, use laquer thinner or terpentine. You need to be outside or in a well ventilated room, though. I know I've cut myself way too many times doing something like this with a knife. Use one of the other alternatives if you can't get laquer thinner/terpentine. They do sell it at any hardware store, though. It also does little tricks on thin paint and annoying stickers. But do it outside or in a well ventilated room like I said. If not you'll start to feel kinda funky and might get a headache.
