Can anyone tell me where I can find this in print? Book, lecture, periodical?
Many thanks!

I have most all of Roy Johnson books and lecture notes, do not remember reading anything like Snap? Where?.

just checked all his books, nothing named, Snap!.

Now that I think about it, could it be in Talisman Magazine. I just looked, it is not in Issue 1, Volume 52 with all Roy Johnson material.

Could you give a hint for the effect? I guess it is a dollar bill trick, and I just don't remember any bill tricks by Roy Johnson.

Harry Lorayne published a rubber band trick called Snap in one of his books.

Originally a manuscript:

Cinch by Shaun Robison looks like the exact same thing but is examinable at the end and has a better more visual method of opening up the bill.

Thanks Magiguy for the reference. I missed that one, I tried to get Roy Johnson to send me a list, but I guess he did not have one. I did get his last set of lecture notes.

That looks like a marketed effect of an easy to do bill change I seen at the local magic shop.

Order placed!!
