Abstract: Luminol (3-Aminophthalhydrazide) serves as a chemiluminescent reagent that, when oxidized by an oxidant in an alkaline aqueous solution, generates excited state molecules. Upon returning to the ground state, these molecules emit energy in the form of visible blue light, which is both striking and aesthetically appealing. This work enhances the outreach of chemiluminescence experiments by substituting laboratory alkaline reagents and oxidants with everyday items like explosive salts and disinfectants (e.g., 84 disinfectant). Targeted gradient science popularization efforts are tailored for different levels of scientific knowledge: (1) Engaging young children and adolescents with entertaining experiments such as “Blue Rain” and “Blue Flame” to foster interest in chemistry through enjoyable educational activities. (2) Designing experiments for undergraduate students with a strong scientific background to utilize chemiluminescence analyzers for measuring peroxide content in explosive salts, thereby enhancing practical problem-solving skills, experimental proficiency, and logical reasoning. (3) Educating the general public through everyday chemical experiments to dispel misconceptions about chemiluminescence, promoting a deeper understanding of scientific principles and improving rational thinking and scientific literacy.
