Magician Performs On America’s Got Talent [VIDEO]

I think I know about 2 magic tricks in my life and one of them consist of a pencil looking like rubber!  I love magic tricks though.  I always think I can be fast enough to see the string or the slip of the other hand yet I never can figure out the trick.  This guy on America's Got Talent called Smoothini is fantastic.  Check out this video of him working his magic and let me know if you have any ideas how he did it!
