Don't steal another magician's style, man. If you do that, then you don't deserve to win a talent show.
But my vote goes for multiplying bottles. It's a more entertaining routine. I can't stand the demo for the Torn and Restored Newspaper. See Harlan walk out, fumble with a newspaper, make a tear, fumble some more, crumple it slightly, fumble some more, make a tear, etc.
I completely agree I didn't like that demo at all. One question, are you just perfroming one trick for your talent show or a routine ? If you are performing a routine and just asking what your final trick should be you should tell us the rest of your routine so we can give you the best possible answer. Because your routine should flow. That is if you are performing a routine.
