How psychics tricked scientists on three separate occasions. Uri Geller, Steve Shaw & Michael Edwards, and Ronny Marcus managed to dupe scientists at the Stanford Research Institute (SRI), The McDonnell Laboratory at Washington University, and Lawrence Livermore National Laboratory respectively. Here’s how, as well as how skeptics James Randi (magician), Dr. Ray Hyman (psychologist), & Martin Gardner (science communicator) responded to the psychic trickery.
“If Uri Geller bends spoons with divine powers, then he’s doing it the hard way.” —James Randi
“Because a good magician can do something shouldn’t make you right away jump to the conclusion that it’s a real phenomenon.” —Richard Feynman
“Geller is at his ingenious best in laboratories where he is being observed by scientists who believe he has extraordinary ESP ability and think—without justification—that they have ruled out every possibility of fraud.” —Milbourne Christopher
Uri Geller is most famous for his claim to be able to bend spoons and keys with his mind. An international star in the psychic circuit, Geller is a Hungarian/Austrian who was born in Israel and lives in England. He claims he’s had visions for many years and may get his powers from extraterrestrials. He calls himself a psychic and has sued several people for millions of dollars for saying otherwise. His psychic powers were not sufficient to reveal to him, however, that he would lose all the lawsuits against his critics. His arch critic has been James “The Amazing” Randi, who has written a book and numerous articles aimed at demonstrating that Geller is a fraud, that he has no psychic powers, and that what Geller does amounts to no more than the parlor tricks of a conjurer.
Geller has been performing for many years. The first time I saw him was in 1973 when he appeared on the Johnny Carson Tonight Show. He was supposed to demonstrate his ability to bend spoons with his thoughts and identify hidden objects, but he failed to even try. He squirmed around and said something about how his power can’t be turned on and off, and that he didn’t feel strong right then. Randi had worked with Carson’s producer to change the spoons and metal items Geller planned to use, as there was a suspicion that Geller likes to work (i.e., soften) his metals before his demonstrations, as would any careful conjurer.

I have always been fascinated and puzzled by the attraction of Uri Geller. I suppose this is because nearly every one of our household spoons is bent and what I would like to see is someone who can straighten them, with his mind or with anything for that matter. Likewise with stopped watches. I have several of those and I would love for someone to use his powers, psychic or otherwise, to make them start running again. Of course, even I can get my stopped watches to run again for a short while by shaking or tapping them, but a permanent fix would be appreciated. There is something mysterious, however, about a person who has built a career out of breaking things.
Uri Geller is an Israeli illusionist, magician, television personality, and self-proclaimed psychic. He is known for his trademark television performances of spoon bending and other illusions. In his Mind-Power Kit he claims to to share with the reader the secrets of his extraordinary powers. The kit also contains a crystal that Uri was personally empowered and a tape with instructions.
Can people move or alter physical objects simply by using a hidden power of the mind called psychokinesis? I have encountered many claims of such powers in the course of my work (since 1969) as a paranormal investigator. And I have pretended to have such ability myself—both as a professional stage magician and mentalist (a magician specializing in apparent psychic feats). In the fall of 2012, I attended a workshop that enabled me to investigate the latest popular expression of psychokinetic metal bending.
The term psychokinesis (formerly telekinesis), or PK, derives from the Greek words for “mind” and “motion.” Together with extrasensory perception (ESP), it constitutes what parapsychologists refer to as “psi” to describe the two seemingly closely related phenomena. However, the existence of psi has never been proven and, indeed, according to a sympathetic source: “Despite decades of research, psi continues to elude physical and quasi-physical theories of how it functions; it operates outside the bounds of time and space” (Guiley 1991, 468).
PK describes the alleged power of mind over matter, including such “micro-PK” acts as subtly influencing how thrown dice will land, or “macro-PK” feats like levitating a table or producing so-called “poltergeist” effects (actually, typically the tricks of children1). Psychokinetic metal bending is another alleged macro-PK phenomenon.
Geller the PK Marvel
It appears that the first major performer of apparent PK metal bending (PK-MB) was Israeli-born former fashion model and nightclub magician, Uri Geller (b. 1946) (Figure 1). Claiming to be guided by super beings from a distant planet, Geller appeared to read minds, bend keys and cutlery with PK, see while blindfolded, and perform other feats—all of which skilled magicians easily duplicate. (I, for example, have driven a car while blindfolded [Nickell with Fischer 1992, 77].) He typically refused to perform when magicians were observing but, nevertheless, was occasionally caught cheating.
Renowned American magician and psychic investigator James “The Amazing” Randi once observed Geller up close. Posing as an editor when Geller performed in the offices of Time magazine, Randi saw the simple tricks behind Geller’s wonderworking. For example, while Geller pretended to cover his eyes as a secretary made a simple drawing, he actually peeked, thus enabling him to appear to read her mind and reproduce the drawing. Again, while supposedly bending a key “by concentration,” Geller had instead bent it against a table when he thought he was unobserved. (For more on Geller’s methods, see Randi 1982.)
Geller was soon imitated by other “psychics” who discovered that they, too, could bend keys and spoons. One was Judy Knowles, who impressed London physics professor and parapsychologist John Hasted with her apparent ability. Hasted invited James Randi to observe tests of Knowles in a lab at Bath. Randi arrived with colleagues and his checkbook, offering Ms. Knowles $10,000 if she successfully passed the test, which was designed by Harry Collins of the University of Bath. Collins had tested other spoon benders, but none had been successful, and some children had been caught cheating.
Briefly, the test involved Knowles holding the spoon in a . . .
