The Incredible Growing and Shrinking Head Illusion is a specially drawn spiral and printed on sturdy cardstock. The spiral can be seen in large auditoriums or can be used in a classroom. People are amazed and always yell "do it again!" The hardest part of this illusion is trying to keep a straight face as your entire audience stares at you in disbelief with their mouths wide open. Try it yourself in a mirror. You are going to love this! Have the audience stare at the spiral and not look away. Count down from ten and when you reach one, tell the audience to look at your face. To their utter surprise and amazement, your head begins to grow like a giant balloon. Spin the disk the opposite direction and your head appears to shrink right before their eyes. Performed by science magician Bruce Kalver at schools, this optical illusion will truly amaze audiences of all ages.
