If you perform Kid Show Magic, then consider Spotty! Kids love it!
An empty bag is shown and then two handkerchiefs magically appear, one blue, one white. Then they change color… the blue is now white and the white, blue! Ok, not convinced, let’s make spots appear… blue on the blue, white on the white! Ok, let’s try again… now the blue spots are on the white and visa versa! But wait! I think one is missing… Spot! Where are you? The bag is turned inside out and there is the face of our dog, “Spot”!
