WOOOOOOW
Kontents, I'm not trying to be negative here, but your responses DO, and I mean DO bring up other questions about it.
"It's really hard to understand" insinuates that there is indeed a solution behidn the magic trick that the spectator coulod easily figure out or even be able to do themselves. I've said responses just like that, they DO bring up other questions.
and no, not all responses bring up other questions. "Very Well Thank You" is one that has no other questions brought up. The spectators GET that you're not going to tell them and that even there is nothing to tell.
If they do ask "but howd you do the trick?" then you can say "magic" and they get the hint, if not and they keep asking questions, then it has fallen on them to be as pestering as possible and no matter what you say will make them leave other than a swift kick to the crotch, I MEAN, simply say that you aren't going to tell them.
Youre response "it's a special deck that I will sell you" implies something about that the decks are "messed up" in some way. You might not be using them, but it's now a possibility to them that decks can be messed up.
One simple google seach for "magic decks" bring up other options for "magic trick decks" and other things as such. The majoirty of the results are for Magic the Gathering, but simply typing in magic into the google box brought up "magic trick deck" and etc. etc.
"It's a trick" again insinuates that it's nothing more than a SIMPLE trick, something that they can figure out or even do.
Magic isn't known for being impossible. Let me try to explain. EVERYONE knows that you somehow managed to accomplish the magic trick in SOME WAY. The magic (at least to me) seems to be the impossiblity of a logical solution. The magic isn't taken as "he can actually make things float." it seems to be more "he put his hands around it, there couldn't have been a string."
Mind reading effects, even ones as simple as forcing a card and "reading" their minds seem to bring up the most interesting responses. Classic Forcing a card, and reading their mind is something that I've gotten different responses to. From, "the cards are marked" to even "he read my eyes."
Short antidote.
I was finishing up my street show with the TOD, i asked the lady to clear her mind, then think of her card. Once I said think of her card I said what the name of her card was. The show ended, I hatted the audience, etc. etc. and the lady came up to me afterwards and said, being completely honest, "I know how you did that last trick. I wasn't thinking of my card when you told me to, but then I thought about it, and then you knew it. You could see it in my eyes, you just read my eyes to know what the card was."
Now here is someone who, not by a flaw in my performance, but it was her own intuition and thoughts that concluded that the ONLY possibly explanation was that I could read things through people's eyes. She had thought of other possibilities, and conlcuded that read it through her eyes was the only possible explanation. That's what magic seems to be these days.
Magic isn't miracles or powers. It's the lack of an explanation that leads them dumbfounded.
So saying that "it's hard to understand" or that there is a trick deck involved leads them to a more rational explanation that is closer to the truth.
I wasn't trying to be negative, just give for a good discussion
