The World’s Greatest Card Trick Can’t Be Taught
May 25, 2021
World-renowned magician David Berglas, now 94 years old, does a card trick that’s so effortlessly simple and dazzling that no one has figured it out and Berglas himself says it cannot be taught.
The trick is a version of a classic plot of magic, called Any Card at Any Number. These tricks are called ACAAN in the business.
ACAAN has been around since the 1700s, and every iteration unfolds in roughly the same way: A spectator is asked to name any card in a deck let’s say the nine of clubs. Another is asked to name any number between one and 52 let’s say 31.
