Ribbon Elf
★Exhibit Content: Bernoulli's principle, airflow transport, and fluid dynamic characteristics ★Interaction: Electromechanical interaction ★Operation: Press the start button of the corresponding color below; observe the colorful ribbons flowing with the wind in the winding pipes and flying out from the animal-shaped outlets at the top. ★Exhibit Description: The exhibit consists of wall-mounted upper and lower functional boxes, multiple sets of winding pipes, colorful lightweight ribbons, a centrifugal fan assembly, and cartoon animal-shaped air outlets. It is a recommended exhibit from the KexMall. The upper box features five cute animal head outlets, and the lower box is equipped with control buttons of corresponding colors, connected by interlaced curved transparent pipes. When visitors press the start button, the built-in fan starts to generate directional airflow, driving the colorful ribbons inside the pipes to quickly shuttle along the pipes and finally fly out from the corresponding outlets at the top. The ribbons dance lightly in the air, vividly demonstrating the power of invisible air, suitable for young children to experience the charm of fluid motion through fun interaction. ★Scientific Principle: This exhibit relies on the basic principles of fluid mechanics. The fan operation creates a continuous directional airflow within the closed pipes. The dynamic pressure generated by the airflow pushes the lightweight ribbons forward along the pipes. The curved pipes continuously change the direction of the airflow, and the ribbons follow the airflow trajectory through the complex channels, intuitively proving that although air is invisible to the naked eye, it has the ability to transmit power and transport objects. The design of pipes with different lengths and bends also allows visitors to indirectly observe the flow characteristics of airflow in confined spaces and understand the basic laws of fluid motion.
