But how to prove this?įaraday devised a system of cardboards attached to each other and to the table by rubber cement in such a way that the top board on which the hands rested could move sideways before that motion was translated to the table.
In the particular case of table turning, the seance participants hoped so much that the spirits would appear that their own muscles made it happen. Having dispensed with the possibility of human emissions, Faraday suggested that the sitters were subconsciously exerting a force with their hands, a phenomenon that would eventually be referred to as the “ideomotor response.” Simply put, this occurs when a thought brings about a muscular response without the awareness of the subject. If it wasn’t chicanery or the handiwork of spirits, in which he did not believe, then what caused the movement? Some scientists suggested that the motion was due to electrical or magnetic forces generated by the sitters, but Faraday demonstrated that this was not the case by covering the table with a variety of insulating materials through which electrical or magnetic forces could not pass. Article contentįaraday became curious enough to attend some seances and witnessed first-hand the movement of tables without any evidence of trickery.
