Does anyone have any information on where to get more information on visually bending a spoon in a spectators hand upwards. Sort of like the way Randi performs it?

I don't know the Randi variation, but did you see the tapes available on this subject? : Bavli's mental bending video, Kuffs' metal bending, and of course Banachek's Psychokinetic silveware. In the last tape, there are different ways to bend a fork in spectator's hand.

I still have to check out banachek.
