Circa 1987 “Catalysts-Secret Agents” is one of fifty-three short educational films originally produced in 1955 for KQED San Francisco as part of the series Tempest in a Test Tube. This series of half-hour episodes illustrates basic chemistry concepts for high school students through live experiments and demonstrations by presenter Dr. Harry Sello. The experiments used in the show were designed by the American Chemical Society’s California chapter and reflect the safety standards of the time. A later, 1987 introduction with Dr. Sello has been removed from this version due to sound and image issues, but identical introductions are available in other Tempest in a Test Tube videos in this collection. This episode, “Catalysts - Secret Agents”, teaches viewers how catalysts help chemical reactions occur more quickly, and demonstrates their role in decomposition, combustion, and industrial chemistry.
