Your assistant finds out the line, selected by a spectator from a book.

Props: a book

Adv. Pre: For this you need a clever assistant who can read your expressions gestures, and movements through which you would convey the exact page and column of the line, selected by the spectator. Also, you must remember that the bandage with which the assistant is blindfolded should be a fake one. It should either have small holes or the middle portion should be of very thin material so that almost every thing can be seen thought it.

First cover the eyes of your assistant with bandage and make him sit somewhere facing the audience. Give the book to any spectator and ask him to select a line of his choice from it. You must see yourself which line he has selected. Now close the book. Hand it over to another spectator to give it to your assistant. As the assistant gets book he opens it and instantly finds out the chosen line.

The moment you come to know the line selected by a the spectator just wipe your face with a handkerchief to give a clear signal to your  assistant that now he must start counting your steps while you walk. Keep the handkerchief inside your pocket and walk as many steps as are necessary to signal the first digit of the page number (suppose page number is 78, then 7 steps at a stretch). Now, break your steps by pausing a little and walk again to convey the second digit (in above example it is 8). For column, you put your left or right hand into the pocket of your trouser or coat to denote whether the chosen line is in left or right column. If there is any third column then put both of your hands into the pockets. Similarly you can convey about the line also but everything should be well planned before the show.

If by chance your assistant has certain confusion in counting your steps, he should cough-to enable you to repeat the whole procedure and to get the exact result.
