The Balducci levitation is a simple magic trick, credited to Ed Balducci. It produces the illusion of a person briefly levitating a few inches above the ground. It is a popular illusion with magicians because it can be performed impromptu and without special equipment.
David Blaine performs this trick. On television, his act (featuring reaction shots of the audience) is intercut with shots of him levitating with hidden mechanical assistance. This allows him to appear to have both feet quite a few inches above the ground in certain shots, something impossible with the Balducci levitation. The controversy among magicians about Blaine's television specials focuses on this, as some consider it to violate one of the rules of the television performance of magic: that the at-home television audience sees exactly what a live audience would see.
