Have you heard the story of the bank robber named McArthur Wheeler in Pittsburgh, Pennsylvania who was told that if he rubbed lemon juice on his face, he wouldn’t need to use a mask to avoid detection, because his face would be invisible to the cameras? This is not a joke it’s true! He bought a Polaroid camera and a couple of lemons, squeezed them and applied the juice to his face. He then pointed the camera at his face and clicked, rotated the camera and clicked. What he finished up with was a photo of the ceiling but no image of his face and fully believed that the lemon juice did the trick.
