Exhibition items description:
Press the "Start" button on the handle, and the fan will start working, generating airflow. Place the balloon on the air outlet, turn the handle, slowly adjust the direction of the air outlet, and then throw the balloon into the basket.
After starting the fan for a period of time, it will automatically shut down when no one is involved.

Scientific principles:
The Airflow Shooting Exhibition in Science Museum is a highly interactive science popularization project that utilizes the Bernoulli principle in fluid mechanics for design. Bernoulli's principle states that in fluids such as air or water, the pressure decreases at higher flow rates and increases at lower flow rates.
In the airflow shooting exhibitions, when the fan is started, the airflow is shot out from the outlet of the launcher, and the ball is placed in the airflow. The ball will be suspended under the action of the airflow. This is because the airflow below the ball is fast and the pressure is low, while the airflow above the ball is slow and the pressure is high. This pressure difference causes the ball to be "trapped" in the airflow.
When the direction of the airflow changes, the ball will also move, but it will never leave the center of the airflow. This is because when the ball deviates from the center of the airflow, the surrounding air pushes it back into the airflow. By adjusting the angle of the launcher and the airflow velocity, participants can attempt to throw the ball into the basket.
This exhibition not only allows the audience to experience the practical application of scientific principles, but also stimulates their interest and desire to explore science. Through practical operation, participants can have a more intuitive understanding of the basic principles of fluid mechanics, while also experiencing the fun brought by science.
