Air-Stream Basketball
★Exhibit Content: Bernoulli ★Interaction: Mechanical + Electromechanical Interaction ★Operation: Visitors press the button, the fan starts, and the balloon is lifted by the airflow from the nozzle. Operate the lever on the rotating mechanism to adjust the direction of the airflow so that the high-speed airflow blows towards the balloon, lifting it into the basket for a successful shot. ★Exhibit Description: The exhibit mainly consists of a fan, balloon, rotating mechanism, button, lever, and basket support. Through the fun interactive way of shooting, it shows visitors the wonders of fluid mechanics and helps them understand the basic connotation of Bernoulli's principle. ★Scientific Principle: The "Bernoulli effect" refers to the decrease in pressure at the interface between an object and a fluid when the fluid's speed increases, and vice versa. The Bernoulli effect applies to all ideal fluids, including liquids and gases, and is one of the basic phenomena when a fluid flows steadily. It reflects the relationship between fluid pressure and flow velocity: the greater the flow velocity, the smaller the pressure; the smaller the flow velocity, the greater the pressure. Examples of applications of the Bernoulli effect include: aircraft wings, sprayers, carburetors of gasoline engines, spinning balls in ball games, etc.
