"One of the strongest cases of possible cheating by Geller was observed by Sandy MacRae, a sound recorder for Thames Television in England. He reported actually seeing Geller bend a large kitchen spoon by hand. It seems that film magazines contain ten minutes of film, but a standard sound tape runs twenty minutes. While the cameramen were busy reloading the film, Geller attempted to divert everyone else's attention by referring them back to a fork he had just broken. But McCrae, who was not busy reloading his equipment, did not turn to the broken fork and said he saw Geller bend the spoon by hand. Geller then called attention to the bent spoon, and the filming resumed. Support for McCrae's story comes from the facts that McCrae was a strong believer in Geller before this incident and that Geller and his associates were obsessively interested in how long it took to reload a film magazine."
