Psychokinesis, or the ability to manipulate objects with the mind, is a notoriously difficult to prove ability. Defiant against attempts to debunk, is the case of Ninel Kulagina. A female soldier in the Soviet Red Army, Kulagina found that whenever she became angry poltergeist activity would manifest in the room around her. With practice, she learned how to focus her power and move objects at will. Scientist Edward Naumov was among the first to test her claims by spreading a box of matches on a table.
