I personally don't like when people expose magic like that. It bugs me.
But at the same time....seeing the Masked Magician...and Mac King reveal the tricks got me into Magic in the first place. If it hadn't been for the World's Greatest Magic Specials, and the Revealed Specials I wouldn't be performing at all.
The cups and balls revealing did bother me. But though it reveals the trick thoroughly, those aren't the only methods to the cups and balls. There are so many sleights and moves that you could still perform it without anyone guessing what is going on. Everyone knows that the magician is going to be one ahead on the cups and balls. Its how to get one ahead...or get the potato under a cup...or a mouse...or whatever you wanna use for a finale...that's the real magic.
The secret isn't the real magic...its the audience reaction...its what the audience walks away with. If they were entertained while you perform the effect then who cares if they figured out the secret behind it.
I know I am probably going to be ridiculed for saying this. But the exposure over the years has helped magic. It got so many people interested in magic again. It was how I got started...and I am sure thousands others. Personally it hasn't hurt anything that I do...I perform the cups and balls and no one has ever said, "well p and t revealed that so I am not gonna watch anymore." I am not saying go around and show everyone how the effect is done...but if they already know...who cares. They were entertained...that's what we are here for...
Sorry if this upsets anyone...but its how I feel.
