Colin Evans was a spiritualist who, as many people believed, could levitate. Colin arranged spiritualistic sessions where he had a lot of fans surrounding him in darkness and chanting. At a certain moment there was a flash of light when everybody could see him levitating.
For a long time there were a lot of believers who were sure that his levitation was real, until some skeptics noticed a cord in every photo, running out of the sleeve of Colin Evans. They finally guessed that Colin was simply pressing the flash button and jumping at that moment.
