The Tin Man's costume was made of leather-covered buckram, and the oil used to grease his joints was made from chocolate syrup. The Cowardly Lion's costume was made from real lion skin and fur. For the "horse of a different color" scene, Jell-O powder was used to color the white horses. Asbestos was used to achieve some of the special effects, such as the witch's burning broomstick and the fake snow that covers Dorothy as she sleeps in the field of poppies.
