Obedient Ball - Customized Science Museum Exhibitions, Campus Community Science Popularization Equipment, Source Manufacturer of Science Exhibitions Description and Introduction of Scientific Principles:
Operating instructions: Press the "Start" button and observe the movement of the ball in the airflow. Function Overview: Exhibitions consist of a vertical pipe and a horizontal U-shaped pipe connected to it, a lightweight ball, and a fan. Press the button to start the fan, and you will see that the small ball moving along the airflow obediently changes its vertical upward direction when it reaches the port on the U-shaped pipe, entering the horizontal pipe. Why is the ball so obedient? According to Bernoulli's principle, the higher the fluid velocity, the lower the pressure; The smaller the flow rate, the greater the pressure. When the fan is started, the vertical upward airflow lifts the small ball inside the tube and moves upward along the center of the airflow. The vertical airflow creates negative pressure inside the U-shaped tube, with the lowest pressure at the lower port. When the ball moves to the upper port of the U-shaped tube, it obediently changes its vertical upward direction under the action of negative pressure, is sucked into the horizontal pipeline, and moves towards the lower port. In daily life, the lifting effect of airplanes, banana balls in football, and spinning balls in table tennis are all applications of Bernoulli's principle. The discovery of Bernoulli's principle is of great significance for human understanding of the characteristics and laws of fluids.
