Every where i look i always see a finale being cups and balls as a street act. so my question is how popular is it...do alot of buskers have them? and also what would be something DIFFERENT that compares to them that would still get the same climax and applause as cups and balls?

Here's a nice alternative:

That is a good one, I use a total rope routine and end with a finish similar to Fiber Optics. Whatever works for your character's personality The reason that the cups and balls is so popular is that a lot of us are to dam lazy to be buskers.. we look at the biggies in the field, Gazzo, Kozmo, Bobby Maverick, and others. they watch the tapes, learn the routine and then do the same dam routine word for word and don't know how to make it THEIRS! Use anything that fits your character, rewrite it so that the words in the patter come from YOUR CHARACTER. Remember YOU ain't Gazzo don't try to steal his act!!!! That will guarantee your success.
