Remember that famous poppy field scene? The one in which the Glinda the Good Witch counters the sleep-inducing effect of the Wicked Witch’s poppies with snow? The “snow” falling on Dorothy, Scarecrow, Cowardly Lion, and Tin Man was made from 100% industrial-grade chrysotile asbestos—despite the fact that the health hazards of asbestos had been known for several years.
Chrysotile, or “white” asbestos, visually resembles real snow. Throughout the late 1920s and 30s, artificial snow made from asbestos was sold under dozens of brand names such as “White Magic,” “Pure White,” and “Snow Drift.”
