For what ride is Pepper's ghost, an illusion technique, used when the Blue Fairy disappears, leaving a pile of fiber-optic fairy dust on the floor?
Pepper's ghost Pepper's ghost is an illusion technique used in theatre, amusement parks, museums, television, and concerts. It is named after John Henry Pepper (1821–1900), a scientist who popularized the effect in a demonstration in 1862. Examples of the illusion are the Girl-to-Gorilla trick found in old carnival sideshows and the appearance of "Ghosts" at the Haunted Mansion and the "Blue Fairy" in Pinocchio's Daring Journey at the Disneyland park in California. Teleprompters are a modern implementation of Pepper's ghost. The technique was used for the appearance of Tupac Shakur onstage with Dr. Dre and Snoop Dogg at the 2012 Coachella Music and Arts Festival and Michael Jackson at the 2014 Billboard Music Awards.
Séance A séance or seance is an attempt to communicate with spirits. The word ""séance"" comes from the French word for "seat", "session" or "sitting", from the Old French "seoir", "to sit". In French, the word's meaning is quite general: one may, for example, speak of ""une séance de cinéma"" ("a movie session"). In English, however, the word came to be used specifically for a meeting of people who are gathered to receive messages from ghosts or to listen to a spirit medium discourse with or relay messages from spirits. In modern English usage, participants need not be seated while engaged in a séance.
