100% guaranteed wining chance with "Lottery Card"!
A spectator is asked to participate in a little "gambling test" to see if he or she has a "Hot Hand" or a sixth sense for winning if you will.
The magicians shows a deck of cards, and the spectator is asked to select a card. Let's assume the spectator chooses the Queen of clubs.
The magician continues and states that the spectator's selection was actually predicted by the magician. The prediction, so the magician claims, is the card itself! OK, not that impressive...But wait! The magician takes out a coin (which can be borrowed) and starts to scratch off the top layer of the back of the spectator's card to reveal the text: "Congratulations, you chose the Queen of Clubs"!!
Finally, the card is visually and magically restored to its original condition!
