Imagine being able to reveal someones exact date of birth using nothing but a deck of playing cards and the tools you have in your mind.
A participant selects their "Birth Card" from a deck of playing cards. You make 2 - 3 "statements" (wink wink, nudge nudge, say no more!) and are then able to reveal their exact date of birth!
Birthday Card by Art Vanderlay is just that.
