no offense... but if you say this is "your favorite trick," this tells the rest of us many things, but 3 very important things.
1- You never perform for anyone, and thus, have no idea what kind of effects are out there and get what reactions.
2- You have never read through a classic magic book (Carney, Close, Cummings, Vernon, etc...)
3- You are merely a move monkey, and have no idea what makes a good performance or a good magical moment.
A word to the wise for the young magic generation. Pick up a copy of Carneycopia (by John Carney of course), and read his introduction. If you are serious about magic, his words will be the best words of wisdom you have received yet (regarding magic that is).
