This year, we once again conducted demonstration experiments at the Graduate School of Biomedical Engineering’s booth during Science Day, held on July 20, 2025, at the Kawauchi Campus. Inoue, Shinohara, Tazawa, Imasaki, and Yabue participated as demonstrators and explainers. Our laboratory conducted three demonstrations: “Let’s Launch a One-Yen Coin with a Small Lightning Bolt,” “Let’s Fly a Drone with Muscle Electricity,” and “Let’s Guide a Catheter with Magnetic Force.” We carefully selected the experiments and prepared our explanations with a focus on what might interest elementary school students. We learned that seeing a one-yen coin or a drone fly truly made the children’s eyes light up, which was a valuable lesson for us as well. Perhaps due to the high temperatures this year, we felt there were slightly fewer visitors than last year, but we still ran out of the 300 pamphlets we had prepared. At the Graduate School of Biomedical Engineering booth, 21 students and staff members worked together to handle the preparation, transportation, and cleanup in the sweltering heat—thank you all for your hard work.
