This is old trick with my spin to it. I got this from Michael Ammar granted I don't think he's the originator to this effect. I'm just telling you who I learned it from, this is one of the 1st magic tricks I mastered. And I still use it till this day it's very easy yet powerful and I love the fact that you can have up to 4 people help you with it.
