Psychokinesis [EPUB ebook] 

During the last four decades, careful laboratory work has shown that man can, to a certain degree, influence the outside world by pure thought. This process is called psychokinesis (PK). This essay, chapter 7 from Psychic Exploration, delves into this very subject. The full volume of Psychic Exploration can be purchased as an ebook or paperback version from all major online retailers and at cosimobooks.com.
