Mentally Colorful (Ron Frost)......$4.50
The magician shows eleven red back cards. He lays the eleven
cards face up on the table showing that they all have different
faces. He says, "We'll only use six cards" and takes five cards
away and places them aside. The magician asks a spectator to
think of a number between one and six. While the spectator is
thinking of a number the magician introduces an envelope
containing his prediction.
When the spectator tells the number he thought of the magician
counts that many and points to the card at that position. The
magician asks the spectator to open the envelope and reveal the
prediction. It matches the card! Not only that, but when the card is
turned over it has a blue back and so does the prediction card!
Finally the magician turns the other ten cards over and they all
have totally different backs!
