The Effect: Six ordinary playing cards with a number on its back that corresponds to its face value are shown one at a time to the audience When the cards are turned upside down, the six card with the number “6” on its back magically turns into a nine, on both its front and back!

This is the one and only card trick that I always perform when doing strolling or close-up magic. The trick is simple to do, can be set up in seconds, and packs flat. Most important, the audiences love it.
