Magic Tricks

The idea wasn't groundbreaking or truly "impromptu" (it can be done with a normal deck of cards, but you will have to set it up in a way that's diffictult to conceal throughout an ongoing performance), but it's practical and it gives you a nice routine, through which you can prcatice a technique which in my opinion is a cornerstone in "hands-off" magic & mentalism.

If that wasn't enough, it's completely free - so you've got literally nothing to lose from downloading the instructions.

I do wish that the manuscript discussed more on various applications of the ideas in use, or different versions of the effect.
