A true magician never reveals the secret and that makes a true magician a famous magician. A magician must treat safeguarding his secrets like safeguarding his money. For a professional magician, his magic tricks are the source of money. Let us consider an example of vanishing a silk using T* prop. Imagine that you have revealed the secret of this trick to some people. Let us consider following effects.
You have ended the fun: You made silk disappear several times before for the people and they were amazed to see it every time you did. You have repeated it few times but they were still amazed. But now they know your secret and if you perform it one more time, don’t expect an applause because you have killed the sense of wonder.
Not your right to reveal the secret: You are not the inventor of vanishing a silk a trick using T*. The original inventor must have designed the T* to keep it a secret. People had praised the inventor to perform vanishing a silk magic routine. But now you have revealed the secret, you have tarnished his reputation as well.
People will further spread the secret: You get emotional and reveal the secret to your close friend or a relative. They even promise you to keep it a secret. But when your friend sees the vanishing silk magic somewhere else by some other magician, they quickly respond to people sitting beside them that they know how to do it, watch magician’s T****. People want to sound smart all the time. They think catching a magic trick is the smart move. Someone rightly said, “three men can keep the secret if two of them die”.
They will ditch you when you perform: Let’s assume you have revealed the secret to your younger brother. Now your cousins visit your home. You show them vanishing a silk magic trick. Your younger brother will shout that he knows the secret and your other cousins will believe that you are no magician it is just a trick, spoiling your performance. Afterwards, your cousins will convince your younger brother to tell them the secret.
