"The center of this exhibit is a carefully constructed electrostatic generation and demonstration system. Through two intuitive operations, visitors can embark on an exploration of electrostatic phenomena: Press the start button to activate the high‑voltage electrostatic generator. Under the influence of the electrostatic field, small balls begin to spin and dance rapidly, transforming invisible electric forces into a captivating dynamic display. Then, turning the handle steadily increases the electrostatic voltage. Once the voltage reaches the air breakdown threshold, bright electrostatic sparks instantly burst forth in the air, accompanied by crisp discharge sounds, creating an immersive scene of scientific wonder. Demonstration of Core Scientific Principles: The interactive forces exerted by an electrostatic field on neutral objects The complete process of charge accumulation and release The physical mechanism of air dielectric breakdown and spark formation The phenomenon of e
