THE BEST METHOD
I like to incorprate my magic into everyday tasks, and situations, to make it seem more REAL and spontaneous, as opposed to , "Hi, can show you a magic TRICK???". That just sounds cheap, and not powerful or captivating.
For example, on a crowded sidewalk, near a bus stop, I often pretend to accidentally drop a crumpled up receipt. Instead of leaning over to pick it up, I lean over slightly, and cause it to LEVITATE
back into my hands.
This is when people begin to STARE
, and some stop to watch as they walk by. I keep on going by making the paper ball levitate around my body and arms. And back into my hand. People begin to ask, "What the? How did you do that?", and that is my opportunity to continue with different effects that involve the audience I've already built up.
The audience grows
, you now have the opportunity to hand out business cards, state your website, ask the crowd for a kind donation, or just walk away (Eery).
Either way, you've built yourself a reputation.
