Since its invention in the mid 1960's by magician Robert Harbin it has been hailed as one of the greatest illusions ever invented due to both the apparent impossibility of the trick, and the fact that unlike many illusions it can be performed surrounded by spectators and withstand the close scrutiny of audience members. Because of the manner in which the illusion is achieved, it is generally performed with a female assistant, and there are limitations on her height and weight. Some of these issues are overcome in Modern Art, an illusion created by Jim Steinmeyer.
