A Halloween Chemistry Show

An outline for the Halloween Chemistry Show Demonstration at Saint Mary’s College, Notre Dame IN, is presented. Organized by Saint Mary’s Affiliate of the American Chemical Society (SMAACS) student club, this show has become an annual event with an average attendance of over 200 people. The club’s main goal is to generate interest in the sciences among children; while stimulating a pursuit for continued education and hopefully future careers in STEM fields. The Halloween Chemistry Show aspires to that goal by providing an interactive experience for all children in attendance while presenting thought-provoking demonstrations for the entire audience.
