Sorry if I offended any of you (didn't mean to). Here was my thinking:
1. I want a flashy opening because if I do the TOD right away, they won't know what's going on until the last part where I read out the cards. Today, I went to the magic store and got a flower production (using a fishing line), silk to flower (inside a tube), color changing silk (extremely easy version), and disappearing silk (thumb or pull) (so it's basically all silks and flowers).
2. By now, the audience already knows how amazing I am  

 . So I'll build up the suspense and then have a huge amount of cheering when I get off the stage (not many of the audience seen magic tricks other than Choose a Card). This trick will probably keep the audience thinking for a long time.
3. I thought that showing the audience a simple trick would be an appropriate way to end my performance, but you guys seem to disagree. What I meant by the "Twisting arm trick" is the one where you twist your arms, put your hands together, and turn both arms to make them straight again. This is one of the tricks that got me into magic. I saw it on TV when a magician showed his entire audience how the trick was done as a finishing trick.
Another reason that I decided to do this is that, chances are, some people in the audience will either know some of my tricks or saw how it's done. After the performance, those people will spread how it's done. Then, lots of people will start saying "Your trick is so easy, you suck" and be thinking that I thought that they wouldn't be able to figure out how my tricks are done. But if I teach them a trick, they won't do so because:
1.They'll think I don't care if they know how a trick is done.
2.They'll be busy with the twisting arm trick.
3.They'll be thankful for teaching them a trick.
Anyways, I still need to come up with a way to make a routine with my gimmicks. I know there's no routine with my specific 4 gimmicks, but if you know a way to combine any two of them, please let me know. Thanks in advance.
