★Exhibit Content: Bernoulli's principle, airflow lift phenomenon ★Interaction: Electromechanical interaction ★Operation: Select the transparent tube you want to observe, insert the blower tube into the corresponding round hole on the front of the tube; observe the small ball inside the tube rising and floating with the airflow; pull out the blower tube, the fan stops, and the ball falls back. ★Exhibit Description: The exhibit consists of a curved base, four transparent vertical tubes, a blower tube, built-in fans, sensor modules, and a control system. It is a recommended exhibit from the KexMall exhibit store. A small vent hole is set at the bottom of each transparent tube, and a red ball is placed inside. When visitors insert the blower tube into the round hole, the sensor detects the signal and starts the bottom fan, sending airflow upward to blow the ball. Visitors can compare the floating states of the balls in the four tubes, intuitively observe the lift changes generated by the airflow, and feel the relationship between flow speed and pressure. ★Scientific Principle: This exhibit demonstrates Bernoulli's principle. In a fluid system, the faster the fluid flows, the lower the pressure it generates; the slower the flow, the higher the pressure. When airflow moves upward, it exerts an upward lift on the ball. When the lift equals the ball's own weight, the ball floats in the air. Bernoulli's principle is widely applied in daily life; airplane wings and sprayers, for example, rely on this fluid law to work.
