Here's an easy magic trick for you. This is one that could go in the middle of your magic show. You are going to put together a short magic show aren't you?
The reason it makes a good middle trick and not an opener or a closing trick is that it has a story to it. Now this isn'talways the rule but generally story tricks don't have the punch between the eyes, knock 'em out qualities you need for an opener. You've got to really try and get people's attention with your opener.
Now you have their attention you can use this magic effect with a bit of a story to it because now your audience thinks it's probably worth staying to watch you.
Then you finish with some more strong magic that finishes with an applause cue. If you throw in lots of SMILES you WILL HAVE a fun magic show that people WILL want to watch.
You can do this. You can put together a show and make people smile. At the end of it you will have a fantastic feeling in your stomach that YOU beat your fears and did something you probably never thought you'd be able to do.
Go on, you can make people smile.
