Ectoplasm (paranormal)

Substance in spiritualism / From Wikipedia, the free encyclopedia

Dear Wikiwand AI, let's keep it short, summarize this topic like I'm... Ten years old or a College student

Ectoplasm (from Greek ektos 'outside' and plasma 'something formed or molded') is a term used in spiritualism to denote a substance or spiritual energy "exteriorized" by physical mediums. It was coined in 1894 by psychical researcher Charles Richet.[1] Although the term is widespread in popular culture,[2] there is no scientific evidence that ectoplasm exists[3][4][5][6] and many purported examples were exposed as hoaxes fashioned from cheesecloth, gauze or other natural substances.[7][8]

Helen Duncan was well known for using dolls and other props as ectoplasm in her séances.
