i learned how to do many magic tricks, and many have invovles having a staged member in the audience. Most of the crazy magic is proformed by actors. David Blaine is crazy though. In his show, at the beggining, he says to the tv, pick a card. then he flicks the deck and ur card appears on top!!!! I watched it twice, and for some reason, I always chose the same card.

That should be ringing alarm bells don't you think?

It's a... arg, i forget the name of it, but basically a trick played on your mind.
When flipping the deck infront of you, the card he wants you to pick is shown for a split second longer, more on that later. Your mind registers the card its most familiar with, which is the majority of the time the card you saw for that split second longer (considering the rest of the cards are usually shown too quickly to be registered by your mind, that compounds the effect)...
At that point, its a simple cut or some sleight to get the card to the top of the deck...
As to how to get the right card to show for longer, multiple ways of doing this fluidly, simple one being placing the card that happens to be infront of the card he expects you to pick lower, so when your finger gets to it, it has to skip across that empty space, resulting in a split second longer... Example:
Say you have 10 cards, and you expect the person to memorize the red card, you start showing the deck starting from the green card, to the orange card... (imagine the 2 rows making 1 card...)
The card infront of the red card is pulled down a bit, so its not shown to the person, and as the finger goes past it, it gives a longer glimpse of the red card to the person... its an awsome effect, try it urself

|As for the rain dances, yeah, I highly doubt that worked... One reason for it "possibly" working was already given, the other being that they likely danced all the time... sooner or later, rain would come, and what would the attributed reason be? The rain dance, of course!
