I'm sharing this little experience of mine not because I think it had an earth shattering effect on my audienec, but in the hope that it may present you with another option when trying to 'jazz it'.
Recently while away on holiday with friends, the conversation turned to cheating at cards. Knowing that I was the magician in the group I was asked if I knew how to count cards, "... like the guy in that Tom Cruise movie???"
Having worked on card counting techniques for a short time, I decided to show off a little with a bit of a demonstration. I looked away while someone shuffled the deck and removed a card. I dealt through the rest of the pack twice (I'm not very efficient yet) and told them the name of the card that was missing. Now, this was OK, except that it was a little slow and not much to look at.
I shuffled the deck again, glimpsed the bottom card and forced it with a classic force. For all intents and purposes, it looked exactly the same as the previous demonstration. This time however I went through the deck at break-neck speed, with the most focused facial expression I could muster at the time. At the conclusion I named the card, which brought sustained applause.
The moral of the story...
An audience doesn't care about method, only effect!!
I know I've learnt an important lesson! ;)
