Years ago, Harry Lorayne wrote that he doubted any card trick will ever compete with a young lady in a miniskirt doing the frug (for those under a 100, that was a seriously sexy dance – in those days). Competition for your audience’s attention grows stronger every day.

Our magic must unequivocally punch our spectators in the nose and get their attention. It must be visible and inexplicable. I’m not sure 4 year olds buy the change bag any more.
Think! Try to see what your audience sees. Video cameras are cheap. Use one.
