Sometimes poltergeist activity is attributed to psychokinesis (PK), the movement of objects through mind power. The majority of poltergeist cases involve an adolescent child and researchers believe that psychokinetic energy may be linked with pubescence. There are, however, other examples where this doesn't apply.
Russian housewife Nina Kulagina became famous in the 1960s because of her psychokinetic powers. Kulagina caused several small objects, including a wedding ring and a bottle, to move across a table. Precautions were taken to ensure that Nina wasn't using hidden magnets or threads and scientists confirmed no force could explain the movements. Other examples of PK include the bending of metals and determining the outcome of events.
In the 1970s, Israeli psychic Uri Geller astounded television audiences with his displays of metal bending. He also claimed to be able to stop the watches of the viewers. Unfortunately Geller never successfully duplicated his powers under laboratory conditions and critics were quick to discredit him.
The theory that PK works using energy fields, either magnetic or electric, was put forward by researchers in 1934, and still holds credence today. The majority of experiences with PK are usually accidental and mistaken for other forms of phenomena.
