Illusion
The art of Illusions comes from making see something odd that tricks their eyes into beliving it or seeing something else. Magic is illusions and thats what makes magic entertaining and very believable. With every trick and movement the magician makes he is creating the illusion he wants you to see. All magic is a type of illusion the magician uses to trick you. Down below are pictures that use illusions.
