Cardistry Master Will Make Your Eyes Cross

I saw this kid on TV last night and I was hooked. His name is Zach and on the show he explained that re reason he is staring so ominously is because he was concentrating so he wouldn't screw up. He also explained that he is pushing the card with his thumb.  And although that might explain it, it doesn't make it any less fascinating or easier to do. I tried. Give it a look see.
