To be honest I bought for the graphic novel as I already had something similar in my repertoire.
I turned out to be way more than I expected (and better than my own version).
I eventually
tried the effect a few times in the last couple of weeks and it just kills.
The reactions are
incredible.
And the trick is not hard to pull off.
On top of that the graphic novel is
really well done ad brings a lot more than just the method to this trick.
A great purchase.
