There's a constant question asked by magicians, "Does it work in the real world?"
It's a legitimate query that warrants a practical response. The problem lies in the fact that performers are focused almost exclusively on the wrong thing. The method. Is it performable with audience members on all sides? Does is reset easily and quickly? Do I have to practice or rehearse before I perform it in public? All questions that are valid from a working pros point of view BUT focuses on all the wrong things. The first question we should be asking is, "What is the effect on the audience?" From there we can ascertain whether the method is practical, whether or not we can pull it off as performers and if we can "sell" it to the audiences we most frequently perform for.
