Marriott by means of a hidden thread.[117] The Italian medium Lucia Sordi was exposed in 1911, she was bound to a chair by psychical researchers but would free herself during her séances. The tricks of another Italian medium Linda Gazzera were revealed in the same year, she would release her hands and feet from control in her séances and use them.

From its earliest beginnings to contemporary times, mediumship practices have had many instances of fraud and trickery.[55] Séances take place in darkness so the poor lighting conditions can become an easy opportunity for fraud. Physical mediumship that has been investigated by scientists has been discovered to be the result of deception and trickery.[56] Ectoplasm, a supposed paranormal substance, was revealed to have been made from cheesecloth, butter, muslin, and cloth. Mediums would also stick cut-out faces from magazines and newspapers onto cloth or on other props and use plastic dolls in their séances to pretend to their audiences spirits were contacting them.[57] Lewis Spence in his book An Encyclopaedia of Occultism (1960) wrote: https://drive.google.com/file/d/1rrXPtB9sGi67HwXA-JNbF6Z9qXtdSQX8/view?usp=sharing

In 1880 the American stage mentalist Washington Irving Bishop published a book revealing how mediums would use secret codes as the trick for their clairvoyant readings.[87] The Seybert Commission was a group of faculty at the University of Pennsylvania who in 1884–1887 exposed fraudulent mediums such as Pierre L. O. A. Keeler and Henry Slade.[88] The Fox sisters confessed to fraud in 1888. Margaret Fox revealed that she and her sister had produced the "spirit" rappings by cracking their toe joints.[89]
It's important to know that the free psychic chat rooms are not for receiving free readings. The free chat rooms are for you to get to know the psychics before you invite them for a private reading. But that being said, it is totally possible to get a free answer or free reading during a free chat. There are many psychics who offer totally free psychic answers on a regular basis. 
Most of the time, when preparing for a reading or a session, your loved ones on the Other Side arrive early - to wait for you. In their excitement, they don’t want to be late, so they find me and we get ready for your session together. Generally, the process is that I can feel the presence of Spirit FIRST, and then I see them SECOND. For me, when a Spirit is present, this feels like I’m climbing up a giant hill on a roller coaster - my heart starts beating fast and my stomach begins to drop. Before I knew what this was - the presence of a Spirit - I thought I just was prone to anxiety attacks! If you have the ability to sense those in Spirit, you may feel a heaviness in the room, or a coolness to the air, too.

The psychical researchers W. W. Baggally and Everard Feilding exposed the British materialization medium Christopher Chambers as a fraud in 1905. A false moustache was discovered in the séance room which he used to fabricate the spirit materializations.[107] The British medium Charles Eldred was exposed as a fraud in 1906. Eldred would sit in a chair in a curtained off area in the room known as a "séance cabinet". Various spirit figures would emerge from the cabinet and move around the séance room, however, it was discovered that the chair had a secret compartment that contained beards, cloths, masks, and wigs that Eldred would dress up in to fake the spirits.[108] https://drive.google.com/file/d/1kJnhZlLDkOvmq2iOrphoSIgGSld-kvX2/view?usp=sharing
The British direct-voice medium Frederick Tansley Munnings was exposed as a fraud when one of his séance sitters turned the lights on which revealed him to be holding a trumpet by means of a telescopic extension piece and using an angle piece to change the auditory effect of his voice.[129] Richard Hodgson held six sittings with the medium Rosina Thompson and came to the conclusion she was a fraud as he discovered Thompson had access to documents and information about her séance sitters.[130]
The British medium Francis Ward Monck was investigated by psychical researchers and discovered to be a fraud. On November 3, 1876 during the séance a sitter demanded that Monck be searched. Monck ran from the room, locked himself in another room and escaped out of a window. A pair of stuffed gloves was found in his room, as well as cheesecloth, reaching rods and other fraudulent devices in his luggage.[80] After a trial Monck was convicted for his fraudulent mediumship and was sentenced to three months in prison.[81] https://drive.google.com/file/d/1JiX0tveUMFHivD4j0nBGY-KRX-iIgNGV/view?usp=sharing
Magicians have a long history of exposing the fraudulent methods of mediumship. Early debunkers included Chung Ling Soo, Henry Evans and Julien Proskauer.[62] Later magicians to reveal fraud were Joseph Dunninger, Harry Houdini and Joseph Rinn. Rose Mackenberg, a private investigator who worked with Houdini during the 1920s, was among the most prominent debunkers of psychic fraud during the mid-20th century.[63] https://drive.google.com/file/d/1wG2ulsB-R-75Z6Sg2tA1niFATuwHYtU8/view?usp=sharing
