To perform a magic trick, you need to know, obviously, how to perform the
trick. But there is another component as well, and it is just as important:
showmanship. You have to feel confident enough in pulling off the trick in
order to also distract your audience from what you are doing. This may be
done through banter or movement or drama. The audience is easily fooled
because they are being entertained. Be wary of someone now who is presenting
something to you with a grand flourish. They may be trying to distract you
from the truth.
