James Randi, during a test conducted by Hasted at Birkbeck College, North was observed to have bent a metal sample with his bare hands. North was tested in Grenoble on 19 December 1977 in scientific conditions and the results were negative. Jean-Pierre Girard, a French psychic, has claimed he can bend metal bars by psychokinesis. Girard was tested in the 1970s but failed to produce any paranormal effects in scientifically controlled conditions. He was tested on January 19, 1977 during a two-hour experiment in a Paris laboratory. The experiment was directed by physicist Yves Farge with a magician also present. All of the experiments were negative as Girard failed to make any of the objects move paranormally. He failed two tests in Grenoble in June 1977 with Randi. He was also tested on September 24, 1977 at a laboratory at the Nuclear Research Centre. Girard failed to bend any bars or change the structure of the metals. Other experiments into spoon bending were also negative and witnesses described his feats as fraudulent. Girard later admitted that he would sometimes cheat to avoid disappointing the public but insisted he still had genuine psychic power. Magicians and scientists have written that he produced all his alleged psychokinetic feats through fraudulent means. Between 1979 and 1981, the McDonnell Laboratory for Psychical Research at Washington University reported a series of experiments they named Project Alpha, in which two teenaged male subjects had demonstrated psychokinesis phenomena, including metal-bending and causing images to appear on film, under less than stringent laboratory conditions. Randi eventually revealed that the subjects were two of his associates, amateur conjurers Steve Shaw and Michael Edwards. The pair had created the effects by standard trickery, but the researchers, being unfamiliar with magic techniques, interpreted them as proof of psychokinesis. John Taylor had tested children in metal bending. According to Gardner, the controls were inadequate as the children would put paper clips in their pockets and later take one out twisted or be left with metal rods unobserved. Randi managed to bend an aluminum bar when Taylor was not looking and scratch on it "Bent by Randi". In other experiments, two scientists from the University of Bath examined metal bending with children in a room which was secretly being videotaped through a one-way mirror. The film revealed that the children bent the objects with their hands and feet. Due to the evidence of
