Magic Tricks

This trick has been controversial for many reasons.
First: The ad is borderline. The spectator cannot stop WHEREVER she wants. Strong spectator management skills are required to control the outcome. And like everything sooner or later it will fail, so be prepared with a proper out.
Second: the prediction card could have done better.
Third: there are better versions out there, there is really nothing "revolutionary" or "new" about this one.
You might like it, you might not, at the end is matter of taste. There are IMHO better open predictions out there.
