To all those asking if it were related to the pass. The answer is no. I do know the accident you are talking about and that is not it. As I said there are no breaks involved period.
To the question about if it can be done with one card, the answer is half a yes and half a no. If you knew how it was done you would understand. But also that reminds me. Using the same sleight I came up with a segway in an ambitious card routiene. I basically get to the point after one card has come up to the top over and over where I think it is about to lose its cleverness so I have "the wrong card" come to top. Of course "i screwed up" so I rectify this with some kinda color change. (Usually shapeshifter). Then I turn it into a kinda double ambitious card playing on them being mates. One of the things I do after I have both of them visible, is I take one and place it in one spot of the deck and take the other and place it in another half. (Or i fan the deck and allow the spectators to put them wherever) and I close up the fan showing both cards face down in seperate locations in the deck. I push them into the deck, maybe shuffle a bit, and then when i spread them I either have them both face up right next to each other (if I am feeling very 'lucky' ill let them shuffle before this one) or I have them face up in other parts of the deck but being the only face up cards. (Meaning, they dont have to be next to each other

) anyway.
I am working on putting together a video to post to let you guys see it in action. But I dont have a camera and even though I goto a multimedia school it isnt easy using their facilities. (Mainly because I am not doing the film programme, but the audio) Anyway. I am torn on if I should try and market it, or use it in my repetoir and hope it helps with my image or whatnot. Anyway.
