An empty bag is shown and then two handkerchiefs magically appear one black, one white. Then they change color… The black is now white and the white, black! Ok, not convinced, let’s make spots appear… black on the black, white on the white! Ok, let’s try again… now the black 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!
