This is a cool card trick I actually developed for print and then published in a column I was doing at the time for the Manhattan Beach Reporter call "Changing Tides." In the column I displayed 16 playing cards in four rows of four each and then instructed readers (or in the case of this video, viewers) how to "shuffle" the cards and then chose one. After than I would pick out their chosen card. It's a really nifty trick. Check it out!
