Have you ever wondered why airplane wings generate lift, or why sailboats can sail against the wind? Behind this lies a fundamental principle of fluid mechanics—Bernoulli's principle. This principle states that in fluids (such as air and water), pressure is lower where velocity is higher, and higher where velocity is lower. When a fast-moving airflow (such as from a blower) rises, its velocity is highest and its pressure is lowest at the center. The surrounding relatively still air has higher pressure, and this pressure difference creates an upward force that can "grab" and lift a lightweight object located at the center of the airflow, suspending it. By precisely adjusting the relative positions of the airflow and the object, we can utilize this invisible force to achieve seemingly gravity-defying precision control. Our large-scale interactive exhibit, "Airflow Basketball" (4800*2880*3250mm), transforms this principle into a fun and challenging competitive game. Participants press a
