While completely blindfolded, you can divine shapes and colors! Hold a blindfold up to the light to prove that no light can pass through it. Put the blindfold on, and... Divine colors - Red, Black, Green! Identify shapes - Star, Circle, Square! And, you can perfectly trace a drawing made by your spectator! While wearing a thick cloth blindfold, you will be able to divine the colors and shapes printed on cards, simply by bringing your fingertips nearby! To prove that you are not peeking through any gaps in the blindfold, you walk a distance away from the cards and continue to divine them accurately. In addition to the enclosed cards, you can identify playing cards, and even perfectly trace a word or drawing made by your spectator. Professional mentalists have made a career out of performing this incredible effect! The impact of this baffling blindfold demonstration is matched only by the ease in which you can learn it.
