I’ve occasionally tuned into Mondo Magic, on A&E, which follows around two close-up magicians doing tricks on the street.
First, the one that wowed. Take a dollar bill from the “victim,” fold it up, and ask him/her to name a foreign country that (s)he wants to visit. Unfold the bill, and presto, it’s changed into currency from the country named. And the included clips had some fairly non-obvious countries, like Costa Rica, Ireland, and Israel. Wow.
Anyway, the second was one done on the home audience. The magician held up a deck of cards, and announced he was going to flip through it (riffling through the deck in his hand by letting the tops of the cards flip past his thumb). The home audience was asked to remember a card from the deck as he flipped through (except the King of Hearts, which was the bottom card of the deck). So he flipped through. He then showed graphics of a few cards, one after the other, and asked us viewers to think “now” when we saw our card. The final result, of course, was showing the card I, at least, thought of: the 4 of diamonds.
Now, as far as I could tell from the flip-through, there were both black and red cards in it, so it’s not like it was the only red card in the deck. My theory:
The deck was “rigged” to not show any card that would be easy to remember, like a two or a face card (as opposed to something like an eight or a ten, which would be hard to make out), EXCEPT for the lone four. And since red cards would be easier to see on a quick flip-through than a black one, chances were maximized that the home audience would remember the four of diamonds, being the most distinct.
Sound right, magic mavens?
