This is a small trick…
Collect a visiting card from one of the members of the audience and fold it in thirds vertically.Tear the card apart along the folds you have made, to make three small pieces.Give the center piece to the owner and ask him to write the name of any dead person.Now give the other two pieces and ask him to write names of living persons on each piece. When this is finished, stand in a corner of the room with your hand back. Ask one of the spectators to keep anyone of the piece in your hand, which you will read without bringing it in front and also announces whether the person is alive or dead.
SECRET IS HERE :
The trick here is very simple.The center piece will have two rough edges and the other two will have only one rough edge. Simply feel the edges and announce it.
Remember that card should not be cut with a blade or a scissor.
