Fun idea, not worth the price of a single trick. It feels like something I'd learn on a DVD or a
book with other tricks.
It's kind of a clever dual reality, so be sure your spectator
doesn't get too nosey. Even in the demo he had to keep pushing his curious spectator back so he
didn't see the prediction. The one person that would especially like to see the prediction doesn't
get to see it...
So a fun idea, but in my opinion not worth selling as a solo trick.
