I'll say it again, the demo video is there to help you decide if this effect is for you, if it fits your performance style, if it will play strong in your opinion. It is not a puzzle with the prize for solving it being that you don't have to pay for it.

In see your point, and this is a discussion with "grey zones". Who invented what and who did not.
I don't see Sankey inventing anything here at all, he is just combining several forces that has been combined before, and his revelation in the envelope is a move from Peter Mariucci thats been known during the last 10 years. So if I already bought the books and tapes and know about the forces, and I already knows the Peter Mariucci move, then I actually think I already paid who should be paid. I see your point if this was an original invention like a totally new way of forcing or a totally new sleigh of hand - but it's not.
You see the reason I guessed how it was done right away, is that there is nothing new in the effect. It's Sankey trying to develop mentalism by combining already known forces and moves. No need to pay him for that.
Look at it this way: Sankey "invention" here is similar to several artist trying to sell their "own" Ambitious Card routine, and a lot of them never ever invented a move themselves (I know Sankey has invented a lot of sleigh etc, but not in this effect). They simply just combined already known moves to fit their own style or ability, and claim to have an AC routine up for sale. So do you think they are paying royalties to the real inventors of the moves they are using - no sorry, they don't. And believe me we are talking top pro magicians here.
I'm perfectly allowed to make up my own version without paying Mr. Sankey for this. However I will always give Sankey credit for the inspiration and as such he will serve the benefit of having his named exposed, and hopefully get new buyers of his products.
By the way, I really hope he is crediting all the real inventors including Mariucci in hs instructional videos - or is he claiming the invention on himself. If anybody bought this item - please let us know who Sankey is crediting on this effect.
And by the way have you ever hear a magician saying "I invented this move, only to discover it was invented 10 years ago by another magician". Well it happens all the time, because we are playing around with these effects, cards, silks etc. And suddenly we think we invented something, which we actually did, somebody just did it before us. So who should have the royalty, and are we allowed to make use of this move, and even further are we allowed to commercialise it and sell it??
It is a pretty difficult discussion, see my post as my spontane thoughts on this. Hopefully we can start a discussion and arrive at a consensus on this topic.
