Binary Code Suitable for all groups. An interactive trick. Lasts about 7 minuets.  This trick requires quite some time to master reasonably difficult, but would be hard to teach anybody. The trick is self working.  This is an ideal trick to convince your audience that you really do have special skills, this goes a long way in helping to make the remaining  demonstrations successful, lets say your audience will be in awe of you and will readily accept anything you tell them

A fully developed THREE-PHASE routine that will not just entertain, but earn you a reputation for genuinely having genius-level memory ability.
