Abstract. Bridging the gap between public interest and scientific understanding is challenging due to complex jargon and the perceived inaccessibility of modern science. While museums and science centers offer opportunities for public engagement, traditional exhibitions often fail to engage visitors deeply. Research suggests that fostering sustained interest in STEM requires educators to cultivate curiosity and engagement through experiential learning and constructivist approaches. Interactive experiences, such as photomicrographic images and electrolysis experiments, have proven effective in enhancing learning and interest. However, chemistry is less frequently featured in exhibitions due to conceptual and technical challenges. Thus, there is a pressing need for interactive and engaging educational opportunities in chemistry. This study addresses this need by designing an automated display system that illustrates acid-base reactions through captivating visual color changes. This interactive exhibition was showcased at the Super STEM Saturday event using traditional laboratory chemicals and common household products. The visually stimulating demonstrations successfully attracted and engaged visitors, enhancing public interest in chemistry.
