I am somebody who mostly works with cards but the talent show for my school is coming up and last year I was ill prepared, I was told there would be around 200 parents, students and teachers at the talent show but after the final count it was around 500 they didn't have a place for everybody because they weren't expecting it. Now as a card magician I want to branch out and do magic that can please all 500 people if that be the case this year. Where should I start, I have royal road to card magic, mnemonica, 13 steps by corrinda, modern coin magic, lessons in card mastery, and tarbells course in magic volume 6. I just don't know where to start I have read since I would most likely find something in there but i'm just stumped. What should I look into? I'm interested in Mentalism and am thinking about performing a pk touch routine or even something with ropes, thanks.
