Cards across

Cards Across is a classic plot in card magic wherein an amount of cards disappears from one pile (of cards) and reappears in a second pile. Typically, this is performed with 2 volunteers, each of which holds a pile.

In J.N. Ponsin's Nouvelle magie blanche dévoilée there is a version called "The Multiplication of Cards while in a Spectator's Hands".

In Robert-Houdin "The Secrets of Conjuring and Magic" (1868) there is an effect called "Mene, Tekel, Upharsin" that describes how to pass a number of cards from one spectator's pocket into that of another.

Performers known for this effect:Leipzig, Paul Le Paul, Al Baker, Howie Schwarzman and Derek Dingle.
