Magic Tricks

I am sorry to write this, but I think I have to. If you are like me a hypnotist, you know how to accomplish pseudo effects. But with this one I didnt have luck till now, which I knew right from the start but thought ill give it a try.
To make it short, to many people will figure out the performance secret and how the gimmick works (or better what it is) somehow. No matter how good you are.
To be fair here, I dont know how many people it will be out of ten, but to much to go out and perform it in front of many people.
My fear of being exposed is to big.
