Although it's not technically magic, demostrations of non-transitive dice and non-transitive coin flips would be an eye-popper.

Yes, Out of This World is a great trick! For those who don't know it, in short, the students/victims guess the color of 20 or so cards, and, in the end get each one right. I use it frequently in my classroom. I also use a modification (shown to me by Larry A. Smith), where they get one wrong, allowing the use of a binomial formula rather than simple independence calculations. I presented on this at the US Conference on Teaching Statistics in 2007 and was invited back to present it in 2009. Some details on the statistics behind it can be found on my website at http://www07.homepage.villanova.edu/mich......tics.pdf The students really do appreciate the trick and I refer to it often when talking about hypothesis testing. You can find a version of it at http://www.youtube.com/watch?v=KCWxSDeGR1I (Thanks to Larry Lesser for the Youtube link - my shtick is slightly different, but the crux of the trick is the same).

"That seems so much better than to use magic in religion class."

both magic and religion are fake; seems like a good match

Except, of course, when (at least) one of them isn't.
