The concept of ectoplasm has haunted the edges of human curiosity for over a century, blending mystery, spirituality, and skepticism. Often portrayed as a slimy, otherworldly substance oozing from mediums during séances, ectoplasm is hailed by some as tangible proof of ghosts and the afterlife. Yet, science dismisses it as a relic of fraud and pseudoscience.
Born in the 19th century amid grief and fascination with the afterlife, ectoplasm was said to bridge the physical and spiritual realms. Mediums claimed to produce this ethereal substance, allowing spirits to materialize. However, investigations often revealed hoaxes involving everyday materials like cheesecloth or egg whites.
Today, with no credible evidence, ectoplasm is largely debunked, yet its allure persists in folklore, movies, and paranormal lore.

What is Ectoplasm?
Ectoplasm, in paranormal terms, is a supposed spiritual substance that physical mediums produce during trance states, enabling spirits to manifest in the physical world. Coined in 1894 by French physiologist Charles Richet, a Nobel Prize winner, the term blends the Greek words ektos (“outside”) and plasma (“something molded”). Richet described it as a mysterious, viscous material that mediums exteriorized, which spirits could shape into forms like limbs, faces, or full apparitions.
Accounts of ectoplasm vary, but it’s often depicted as a slimy, gauze-like, or mist-like substance emerging from a medium’s body—typically the mouth, nose, ears, or even skin pores. Witnesses from the Spiritualist era reported it as a gelatinous fluid that could shift from clear to opaque white, sometimes forming tendrils or human-like features.
Some claimed it had a pungent odor, likened to ozone or decay, and was sensitive to light, disintegrating under bright conditions. French researcher Gustav Geley noted its variability: it could appear as a vaporous cloud, fine threads, or a dough-like mass capable of complex shapes.
In spiritualist theory, ectoplasm acts as a material bridge between the living and the dead. Mediums allegedly draw on their vital energy, combined with spiritual forces, to produce it. This process was said to be physically taxing, with claims that disturbing ectoplasm could harm the medium, discouraging close inspection during séances. The concept ties to earlier ideas like ectenic force, a hypothetical psychic energy enabling psychokinesis and materializations.
Scientifically, paranormal ectoplasm is unrelated to the biological term for amoeba cytoplasm. Instead, it’s been repeatedly exposed as fraud, often involving mundane materials like muslin or starch. Despite this, ectoplasm persists in esoteric traditions, such as Brazilian Spiritism, where it’s seen as a plastic intermediary between matter and spirit. To understand its allure, we must explore its roots in the Spiritualist Movement.
The History of Ectoplasm in the Spiritualist Movement
The rise of ectoplasm is tied to the Spiritualist Movement, which swept across Europe and America in the mid-19th century. Triggered by the 1848 Fox sisters’ claims of spirit communication in Hydesville, New York, spiritualism offered solace amid tragedies like the American Civil War and World War I. Grieving families sought mediums to connect with lost loved ones through séances, table rapping, and materializations. Ectoplasm emerged as a centerpiece, symbolizing a physical link to the afterlife.
Charles Richet formalized the term in 1894 while studying mediums like Eusapia Palladino. His work built on earlier psychical research into psychic force by scientists like William Crookes and Camille Flammarion.
By the early 20th century, ectoplasm was a hallmark of physical mediumship, with researchers like Albert von Schrenck-Notzing and Gustave Geley documenting it through photographs and experiments. These images, showing ghostly forms, captivated the public and sparked debates in scientific circles.
The Spiritualist Movement thrived on societal upheaval, blending mysticism with pseudo-scientific inquiry. Organizations like the Society for Psychical Research (SPR) investigated claims, aiming to bridge science and spirituality.
Ectoplasm evolved from vague notions of spirit matter to a defined phenomenon, with mediums like Eva Carrière producing elaborate displays. However, as photography and scrutiny advanced, frauds were exposed, denting spiritualism’s credibility by the 1920s.
The movement also reflected gender dynamics. Most mediums were women, and ectoplasm’s emergence from bodily orifices carried symbolic weight, evoking Victorian themes of birth and sexuality. This made séances both spiritual and sensational, drawing crowds eager for proof of the afterlife. Ectoplasm became a cultural artifact, embodying hope, deception, and the quest for meaning.

Famous Cases of Ectoplasm and Notable Mediums
The allure of ectoplasm shines through the stories of mediums who claimed to produce it, often under intense scrutiny. These cases, spanning Europe and America, highlight the phenomenon’s peak and the controversies that followed.
Helen Duncan: The Last “Witch” of Britain
Helen Duncan, a Scottish medium nicknamed “Hellish Nell,” was a prominent figure in the 1930s. During séances, she produced copious amounts of ectoplasm, often described as white, cloth-like material flowing from her mouth to form spirit figures. Her sessions in Edinburgh and London drew crowds, with participants reporting spectral faces and hands.
In 1933, investigator Harry Price attended a séance and seized a sample, revealing it as cheesecloth mixed with egg white, likely swallowed and regurgitated. Duncan’s defenders argued the material transformed under spiritual influence, but skeptics noted her use of dim lighting and no-touch rules.
In 1944, she was convicted under the Witchcraft Act of 1735 for fraudulent mediumship, earning her the title of Britain’s last “witch.” She died in 1956, maintaining her claims, with some supporters still believing her ectoplasm was genuine.
Eva Carrière (Marthe Béraud)
Eva Carrière, also known as Marthe Béraud, was a French medium whose ectoplasmic displays from 1910 to 1913 stunned Europe. Working with Albert von Schrenck-Notzing in Munich, she produced ectoplasm that formed faces, hands, and torsos during séances. Photographs showed eerie, paper-like forms emerging from her body, which Schrenck-Notzing called ideoplasty.
However, critics like Donald West later identified these as cutouts from magazines like Le Miroir, featuring figures like Woodrow Wilson. Magician Carlos María de Heredia replicated her effects using gauze and pins, exposing her methods. Carrière’s séances, held in darkened rooms, relied on suggestibility, and her career waned after repeated exposures.
Mina “Margery” Crandon
Mina Crandon, known as “Margery,” was a Boston medium in the 1920s who gained fame for her ectoplasmic hands and voices. Supported by Arthur Conan Doyle, she conducted séances under the scrutiny of the Scientific American committee, which offered a prize for genuine phenomena. Her ectoplasm included hand-like forms that rang bells and moved objects.
In 1924, biologist Walter Franklin Prince identified an ectoplasmic hand as carved animal liver, and further tests revealed muslin and gelatin. Margery’s husband, a surgeon, was suspected of aiding her deceptions. Despite initial support, her credibility collapsed, marking a blow to spiritualism in America.
Franek Kluski
Franek Kluski, a rare male medium from Poland, gained attention in the 1910s and 1920s for producing ectoplasmic molds of hands and feet. In Warsaw, he conducted séances where ectoplasm reportedly formed detailed paraffin casts, preserved as evidence. Gustave Geley praised these as proof of spirit materialization.
However, skeptics noted that Kluski’s molds matched human anatomy too closely, suggesting he used his own limbs coated in wax. His séances, held in near-darkness, limited verification, and later analyses pointed to mundane materials like fat and resin.
Einer Nielsen
Danish medium Einer Nielsen was celebrated in the 1920s for ectoplasmic limbs and figures. His séances in Copenhagen featured ghostly arms that touched participants.
In 1922, the Oslo Psychic Research Society caught him hiding butter muslin under his clothing, used to simulate ectoplasm. Nielsen’s career faltered after multiple exposures, with critics noting his reliance on confederates and sleight-of-hand.
Kathleen Goligher
Kathleen Goligher, an Irish medium, worked with engineer W.J. Crawford in Belfast during the 1910s.
Crawford’s book, The Reality of Psychic Phenomena (1916), detailed her ectoplasmic rods that levitated tables. His photographs showed thread-like structures, but physicist Edmund Edward Fournier d’Albe debunked them in 1921, identifying muslin and starch. Goligher’s séances, conducted in a family circle, were criticized for lax controls, and her phenomena ceased under stricter conditions.

Thomas Glendenning Hamilton
Canadian physician Thomas Glendenning Hamilton documented ectoplasm with medium Mary Marshall in Winnipeg during the 1920s. His photographs showed ectoplasm forming faces, but analysis revealed tissue paper and magazine clippings, including images of actress Mary Pickford. Hamilton’s work, initially respected, was later dismissed as naive, with critics noting his emotional investment in spiritualism after losing his son.
Stanisława Popielska
Polish medium Stanisława Popielska produced ectoplasmic forms in the 1910s, often alongside Kluski. Her séances featured misty shapes and partial materializations. The Metapsychical Institute in Paris studied her, but investigators found cotton and adhesive in her ectoplasm. Her case faded as spiritualism declined in Poland.
William Hope
British medium William Hope, active in the early 20th century, specialized in spirit photography, capturing ectoplasmic forms on film. His images, showing veiled figures, were exposed by Harry Price as double exposures using cotton wool and paint. Hope’s work with the Crewe Circle fueled spiritualist fervor but collapsed under scrutiny.
These cases reveal a pattern: dim lighting, restricted access, and eventual exposure. Mediums exploited grief and limited technology, but believers like Arthur Conan Doyle and Oliver Lodge saw ectoplasm as proof of the afterlife. Skeptics, including magicians like Harry Houdini, countered with demonstrations of trickery, highlighting the era’s blend of wonder and deception.
Scientific Investigations and Debunking of Ectoplasm
The scientific community has long scrutinized ectoplasm, seeking to explain its alleged existence through rigorous testing.
From the late 19th century, researchers attempted to validate or debunk claims, often uncovering fraud. Below is an in-depth look at key investigations, their methods, and findings, revealing why ectoplasm remains unsupported by science.
Early Psychical Research
The Society for Psychical Research (SPR), founded in 1882, was among the first to investigate ectoplasm. Researchers like Frederic W.H. Myers and Henry Sidgwick examined mediums like Eusapia Palladino.
In 1895, the SPR tested Palladino in Cambridge, noting ectoplasmic effects like table levitation but suspecting trickery due to her freeing her hands in dim light. Their 1898 report concluded her phenomena were likely fraudulent, setting a precedent for skepticism.
Charles Richet, despite coining ectoplasm, approached it cautiously. His 1905 experiments with Eva Carrière used early spectrometry and photography, finding no unique chemical signatures in samples, which resembled organic matter like egg white. Richet admitted the need for stricter controls, acknowledging fraud risks.

Harry Price’s Investigations
Harry Price, a prominent psychical researcher, conducted extensive tests in the 1920s and 1930s. His 1931 study of Helen Duncan involved seizing ectoplasm samples during a séance. Chemical analysis revealed cheesecloth, egg white, and traces of potassium permanganate (used for odor).
Price’s book, Leaves from a Psychist’s Case-Book (1933), detailed how mediums hid materials in clothing or body cavities. His work with the National Laboratory of Psychical Research exposed dozens of frauds, including William Hope’s manipulated photographs.
Houdini’s Crusade Against Fraud
Magician Harry Houdini was a fierce skeptic, attending séances to debunk ectoplasm. In 1924, he joined the Scientific American committee evaluating Mina Crandon. Houdini designed a “fraud-proof” cabinet to restrain her, and no ectoplasm appeared.
He later replicated her effects on stage using gelatin and muslin, publishing his findings in A Magician Among the Spirits (1924). Houdini’s demonstrations showed how mediums used sleight-of-hand and props.
Crawford and Fournier d’Albe
Engineer W.J. Crawford studied Kathleen Goligher from 1915 to 1919, hypothesizing that ectoplasm was a “psychic plasma” with measurable weight. His experiments used scales to detect weight shifts during séances, claiming ectoplasm transferred mass from the medium.
However, physicist Edmund Edward Fournier d’Albe retested Goligher in 1921, using infrared photography and stricter controls. He found muslin and thread, concluding Crawford’s data resulted from mechanical tricks, not supernatural forces.
Schrenck-Notzing’s Ideoplasty Experiments
Albert von Schrenck-Notzing conducted controlled séances with Eva Carrière from 1910 to 1913, using cameras and magnesium flashes to capture ectoplasm. His book, Phenomena of Materialisation (1914), claimed ectoplasm was a psychically molded substance.
However, later analyses by Eric Dingwall showed Carrière’s ectoplasm contained paper, cotton, and human hair. Schrenck-Notzing’s lax controls—allowing dim lighting and no physical searches—undermined his findings.
Chemical and Biological Analyses
In the 1920s, samples of ectoplasm were tested in laboratories. A 1922 study by the Sorbonne analyzed material from Stanisława Popielska, finding cellulose, protein, and fatty acids consistent with cheesecloth and animal tissue.
A 1930 investigation by the London Psychical Laboratory identified egg albumin and starch in samples from Einer Nielsen. Modern forensics, unavailable then, would detect such deceptions instantly, as these materials lack unique spectral signatures.
Psychological Explanations
Psychologists like William McDougall explored ectoplasm through human perception. His 1920s studies suggested suggestibility and confirmation bias made séance participants see ectoplasm in ambiguous shapes.
Dim lighting, emotional stakes, and group dynamics amplified illusions, a phenomenon called pareidolia. This explains why ectoplasmic faces often resembled known images, like magazine cutouts.

Modern Scientific Stance
By the 1930s, ectoplasm was largely discredited. The American Association for the Advancement of Science (AAAS) in 1935 declared no evidence for supernatural substances, citing fraud and lack of reproducibility.
Today, no peer-reviewed study supports ectoplasm. Advances in spectroscopy, DNA analysis, and imaging technology confirm that alleged samples match mundane materials. Paranormal claims of ectoplasm as ghostly residue are dismissed as misinterpretations of natural phenomena like mist or dust.
Despite this, esoteric groups like Brazilian Spiritists maintain belief, citing rare cases like Divaldo Pereira Franco’s 1977 photographs. These lack independent verification and are criticized for poor documentation. Science demands repeatable, controlled evidence, which ectoplasm consistently fails to provide.
Ectoplasm in Popular Culture
Ectoplasm has left an indelible mark on popular culture, transforming from a spiritualist claim to a symbol of the supernatural. Its slimy, ghostly imagery captivates audiences across media, blending horror, humor, and mystery.
Movies: From Ghostbusters to Horror Classics
The 1984 film Ghostbusters popularized ectoplasm as green, gooey slime left by ghosts like Slimer. This comedic take made ectoplasm a household term, with lines like “He slimed me!” becoming iconic. The 2016 reboot and Ghostbusters: Afterlife (2021) continued this, depicting ectoplasm as a spectral residue.
Horror films like The Uninvited (1944) and Poltergeist (1982) use ectoplasm-like mists to signal ghostly presence, tapping into its eerie aesthetic. Indie films, such as The Haunting in Connecticut (2009), show ectoplasm as a dripping, ghostly fluid during séances, reinforcing its spooky allure.
Literature: From Spiritualism to Fiction
Arthur Conan Doyle’s The History of Spiritualism (1926) endorsed ectoplasm, influencing early 20th-century fiction. H.P. Lovecraft’s The Dunwich Horror (1929) hints at ectoplasmic entities, blending cosmic horror with spiritualist themes.
Modern novels like Stephen King’s Bag of Bones (1998) reference ectoplasm as ghostly residue, while Ghosts in Popular Culture and Legend (2016) explores its mythological roots. Paranormal romance novels, such as those by Nalini Singh, use ectoplasm as a plot device for spirit interactions, appealing to fans of the supernatural.
Television: Paranormal Dramas and Reality Shows
TV shows amplify ectoplasm’s mystique.
In Supernatural, ectoplasm appears as black, oozing residue in episodes like “Hollywood Babylon” (2007), tied to vengeful spirits.
The X-Files features ectoplasm in “Clyde Bruckman’s Final Repose” (1995), linking it to psychic visions. Reality shows like Ghost Hunters (2004–present) and Paranormal State (2007–2011) investigate ectoplasm-like mists, often debunking them as dust or condensation caught on camera. These shows keep ectoplasm relevant, blending skepticism with spectacle.

Contemporary artists use ectoplasm as a metaphor for fluidity and the unknown, bridging spiritualism and modern expression.
Ectoplasm’s cultural staying power lies in its ability to evoke both fear and fascination, making it a timeless symbol of the supernatural.
Ectoplasm: Is It Real Ghost Evidence?
In 2025, science firmly rejects ectoplasm as a paranormal phenomenon. Advances in biology, physics, and forensics find no evidence for a substance bridging physical and spiritual realms. Paranormal investigators sometimes report ectoplasm-like mists or orbs, but these are explained as optical illusions, dust particles, or lens flares. For example, infrared cameras often capture atmospheric moisture mistaken for ectoplasm.
Modern mediums, particularly in Brazilian Spiritism, claim rare ectoplasmic manifestations, as seen in 1977 images of Divaldo Pereira Franco. These lack peer-reviewed validation, with critics noting poor lighting and no independent testing. The ubiquity of smartphones and high-resolution cameras should yield clear evidence, yet no credible footage exists. Speculations linking ectoplasm to quantum energy fields or bio-photons are dismissed as pseudoscience, as these phenomena have no connection to spiritual claims.
Paranormal communities on platforms like Reddit discuss ectoplasm as a romanticized relic, but even believers admit the lack of proof. Science demands reproducible evidence, and ectoplasm fails to meet this standard, relegating it to folklore and entertainment.
