The Demon Spider Web Illusion
This trick was invented by British magician J.F. Orrin. A card is chosen and then the magician causes it to vanish. The spider is shown at the middle of the web and the magician explains that the spider is very good at finding missing cards. The web is spun and the audience sees the chosen card gradually appearing at the feet of the spider. It’s a novel way of finding a chosen card. The illustration is from a Davenports catalogue.
