Magic Tricks

Just performed this the other day for about 9 coworkers and killed them with it, did it a second time right away and totally blew them away. I totally downplay the math and make a big deal about the pen I use as I have them draw what they choose and then I take the pen back carefully and hold it tightlty and rotate it as if I'm getting a psychometric reading off of it. I'm dead serious...until I get the image....I smile and then draw it as if it came to me all of a sudden. As soon as they see my drawing they gasped and blurted out no way. No word of a lie, I have one of them believing that I really do have powers.
