Show a friend 4 drawings and put your phone face down on the table. Ask this friend to name any of the drawings. You then claim you knew what they would choose by leaving only 1 of the drawings displayed on your screen. And when you turn over your phone, it is the image he had picked!
Easy to do
You display a picture of your alarm clock. Without showing it to your spectator, you ask him to name any hour, and it matches the hour displayed on your alarm clock! You can even e-mail the picture to your spectator!
