As a spectator, it can be so exciting to see David Blaine levitate, or Copperfield vanish the Statue of Liberty vanish on live TV, but as a street magician such as myself, all I can really do at a table is a couple of coin vanishes, or at best, some impressive card tricks! I think it is enjoyable as it lets people see other ordinary people supposedly 'bend' reality. Everyone knows it is not real, and is just a clever gimmick, or practised-to-perfection sleight-of-hand, but everyone just accepts it, and for a split second, believes that it is real.
As a magician however, I love seeing spectators faces light up in bewilderment, it is a great confidence booster and is a fun hobby.
Oh, and it's great in creating WTF moments that will stay in spectators minds forever:D
