Surging wisdom

By demonstrating the scene of scarves dancing under the action of airflow and experiencing firsthand the blowing of wind, the air is visualized, helping visitors realize that air is not only everywhere, but also a form of kinetic energy. The exhibit is a large-scale interactive demonstration device consisting of a blower, circular base, silk scarf or lightweight sphere. The base is divided into inner and outer rings, with the blower on the outer ring and the air outlets distributed around the outer ring. The silk scarf flutters in the air under the action of the wind, presenting a jumping scene like a fountain. Visitors can stand on the base, feel the wind, shake the scarf, and experience the charm of combining science and art. The exhibit visualizes air through demonstrations and interactions, demonstrating that air is a form of kinetic energy. The interaction between air and objects is an important research topic in aerodynamics. Target audience: Full age display format, scientific, artistic, mechanical and electrical demonstration device operation instructions (audience experience).

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Wind is a natural phenomenon on Earth, caused by solar radiation heat. The sun shines on the surface of the Earth, and different parts of the Earth's surface are heated differently, producing temperature differences, which in turn cause atmospheric convection to form winds. Wind energy is the kinetic energy generated by the flow of air. A form of conversion of solar energy. Due to uneven heating of various parts of the Earth's surface caused by solar radiation, the pressure distribution in the atmosphere is unbalanced. Under the action of a horizontal pressure gradient, air moves horizontally to form wind. Wind energy utilization is a comprehensive engineering technology that converts the kinetic energy of wind into mechanical energy, electrical energy, and thermal energy through wind turbines.
