Piano Card Trick
Piano Card Trick is a card effect where the cards are placed between the spectators fingers. When separated into piles, one card seems to pass from one hand's pile to the other.
The trick is very old, but got it's name from Imro Fox who would ask the volunteer to spread their hands on the table as if to play a piano.
