The Asrah levitation is an illusion effect whereby the magician hypnotizes an assistant and commands them to recline on a table or couch. The assistant is then fully covered with a cloth and levitated under the cloth. The form of the assistant is still visible while levitating. Moments later, the assistant slowly floats down. As the magician pulls off the cloth, the assistant vanishes instantly. This illusion is credited to Servais Le Roy and was first performed in 1902.
