Fun Basketball Shot
★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 toward 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 a basket, the exhibit shows visitors the wonders of fluid mechanics and helps them understand the basic meaning of Bernoulli's principle. ★Scientific Principle: The "Bernoulli effect" refers to the decrease in pressure on the interface between an object and a fluid as 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 of steady fluid flow. 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: airplane wings, sprayers, carburetors of gasoline engines, spinning balls in ball games, etc.
