They do several tricks where they pretend to reveal what they are doing, revealing how the trick normally works I think, and then proceed to do something that makes it apparent that is not actually what they are doing.
They have a particularly gory version of sawing a woman in half for example. I think it is on youtube somewhere, pretty solid.
But yeah, I don't think you could say that they reveal tricks that "belong" to other magicians. They reveal the basic stuff.
They do a couple exposures. Cups and Balls, Blast off, and a new escape in their act that you can choose to cover your eyes for or not.
Cups and Balls and Blast Off aren't exactly carefully guarded secrets... what are you referring to?
