Effect: A playing card vanishes when placed in a glass tumbler.
Secret: You need a piece of clear plastic the same shape and size as a playing card. Place this on top of a pack of cards. Cover the cards with a handkerchief and apparently remove the top card in the handkerchief. You actually take the sheet of plastic. Show a glass tumbler and ask a spectator to push the card, still covered by the handkerchief, into it. Whisk the handkerchief away and the card has vanished. Being transparent, the plastic cannot be seen from even a short distance away.
