People will probably hate me for saying this, but i know where you are coming from. I am a broke college student and i try to figure out how to do tricks by watching them over and over. I also get a lot of satisfaction in knowing that i figured it out. Not to mention i learn better by figuring stuff out myself as opposed to having someone show me. Anyway, all that to say go to youtube and watch other people perform the trick because in the demos they like to cut out things that might reveal it, and you can also see it from different angles and sometimes find someone doing a poor job of it and in effect revealing it. While i dont think people should post that kinda stuff up, I am going to take advantage of it because it saves me money. Thats my 2 cents.
