Ink on the Deck by Juan Pablo
"The Ink on The Deck": imagine that a spectator freely chooses two cards from a deck, (for example the ace of hearts and the Six of Clubs) now the magician takes on his fingers some "invisible" ink from a marker and when passing his fingers over the edge of the deck of cards, the name of one of the chosen cards magically appears written, the "Ace of Hearts"!.
Now the magician makes a rifled with the deck of cards and the card that is written on the edge of the deck (the Ace of Hearts) is magically and visually transformed into the second chosen card the "Six of Clubs" and immediately the magician can show the deck of cards as a normal deck of cards! leaving clean at the end of the trick.
"The Ink on The Deck" is very easy to do and is useful for magicians who perform close up performances because it is a super original, visual magic effect and it resets in five seconds.
