This image captures the finale of Scientific Sue’s Chemistry of the Celts show, where she performs a controlled demonstration of a grain-dust explosion. A bright flame erupts from a small box on the table, illustrating how tiny airborne particles—such as flour or grain dust—can combust rapidly under the right conditions. Sue stands beside the demonstration, engaging the audience as she explains the science behind historical grain-store explosions. The backdrop and props highlight the show’s blend of Celtic storytelling and hands-on chemistry.
