Call the selected map

Take any number of cards, which is a multiple of three, for example, 27. Speaking to the audience that you took it so many cards, you can not. Then tell the audience what you would call any card, which the viewer chooses. Next, invite any viewer deck and let it face up, choose a card and ask them to write it on a piece of paper. Then you turn the deck that you gave the audience and quickly lays out the cards in the stack 3 in the clear. It is desirable that when a foldout maps, they are not looking. Then ask the audience who chose a map of where it is located. Then gather all pile into one deck face down, with a stack of the desired card accidentally must be secondary. Then repeat again, then again and again. After the fourth alignment of you already know, what it was a map. This is the average card average stack. At the same time talk about it you still have not. Shuffle the deck, ask her to remove, and then, taking off one card, peer at them, pretending to hesitate, choose the map viewer. The secret of focus is as follows. It should be numbered cards in the order in which they are laid. For example, the viewer selected the deuce of clubs twenty-fifth card in order of date. You will then lays out the cards in a stack 3 follows.
