2 hours is quite common (in a theater)
their would (of course) have to be an interval and proper seats...
okay what about this
act 1 - magic
1. angle zero, but what happens is that the corner goes to any seat number the person wants (I dont know if this would or could work)
2. maybe a manipulation act? (check out the 1 on 1s)
3. misers dream (maybe an opener?)
5. im not sure - but thats alot of differant routines already that you could use. less is more
act 2 - mentalism
(in order of what you would do, when you would do it)
1. pk touches
2. pyscho force
3. for andruzzie
if you think of anything else then sure, but it HAS to be good material, if your gonna entertain 500 people for 2 hours you need be awsome at what your doing
but you also need themes, maybe gambling...
for the first act you could explain that con artists use sleight of hand for their cons, especially their best ones (misers dream + manipulation), often they use everything can use and needto think of something on the spot (angle zero) but it almost always still works (show were the corner is)
break.
now obviously they use sleight of hand, but sometimes they use pyschology, and when they do, people dont realize whats happening when its happening (pk touches), sometimes they do it so people dont realize that their falling into a trap (pyscho force), ovviously, when you use all these skills together, incredible thinks happen (for andruzzie).
now you would have to give examples of con artists, and all that... but that is the kind of structure you should have - a theme or two, and you twist the presentation so it all works together
