Abstract: This paper elucidates the carbonization and hydrophilization processes involved in the “magic transformation” of wood into a water purifier, along with its purification efficacy and underlying mechanisms. The wood-based purifier effectively removes contaminants such as microplastics (≥ 10 μm), organic dyes, and antibiotics from water, demonstrating successful purification of natural water samples from Nanjing’s Xuanwu Lake. Through hands-on demonstrations, informational displays, video presentations, and interactive quiz sessions, this project achieved public engagement and delivered accessible science communication. The study presents a novel practical model for chemical science education.

Key words: Wood, Carbonization, Hydrophilic treatment, Water purification
