The Secrets of Magic and Fantasy

I'm watching a show right now that reveals the secrets of magic. The guy doing the magic tricks has a mask on ... I find myself wondering if it is really so "unethical" to the extent to where he has to wear a black mask. I think it's cool to find out how magic tricks are done. I love the way we cab creatively trick the human mind into believing unreal things. Fantasy is what makes life fun. Don;t you think?
