In 1935, Karachi sent a challenge to the skeptics, for 200 guineas to be deposited with a neutral party who would decide if the rope trick was performed satisfactorily. His terms were that the rope shall rise up through his hands while in a sitting posture, to a height of ten feet, his son Kyder would then climb the rope and remain at the top for a minimum of 30 seconds and be photographed. The rope would be an ordinary rope supplied by a well-known manufacturer and would be examined. The place could be any open area chosen by the neutral party and agreed to by the conjurers, and the spectators could be anywhere in front of the carpet on which Karachi would be seated. The conjurers of the Occult Committee refused to accept Karachi's terms.
