Here's a recommendation for ya - The Straight Dope. "Fighting Ignorance since 1973 (it's taking longer than we thought)".
Cecil Adams may well be the world's smartest man (ahem). I came across the site doing magic research. Try Cecil on "how did Uri Geller bend spoons?" ; "How did David Copperfield make the Statue of Liberty vanish?" ; The Indian Rope Trick; "How Psychics can tell you stuff they couldn't know about you" - with help from Ian Rowland or, for a different kind of 'magic' debunking Carlos Castaneda. (What the hell IS debunking, anyway? - rudely awakening?)
Have fun searching their archives, and hey, why not ask Cecil a question?
And while we are in a debunking mode - don't forget the Skeptical Dictionary. I'll pick a random page, about the Sokal hoax.
