Airflow Shooting

Purpose & Scientific Principle

The exhibition item shows the relationship between fluid, flow rate and pressure in Bernoulli's principle, that is, the greater the flow rate of the fluid, the smaller the pressure; the smaller the flow rate, the greater the pressure. Press the start button and you can see that the ball gradually moves upward in the direction of the airflow from the initial static state. This is because when the airflow jets towards the small ball, the speed in the middle of the airflow is high and the pressure is low. The speed of the surrounding airflow is small and the air pressure is strong. The surrounding air will push the ball back to the middle of the airflow to prevent it from falling. Participants adjust the position of the launch port to change the direction of the air flow. The movement of the colorful ball changes with the change of air flow pressure, thereby controlling the direction of the ball movement. Using this principle, the ball can be thrown into the ball with air.

How to Operate

Press the start button, the fan starts to work, adjust the size of the airflow with the knob, place the ball at the air outlet, operate the handle to control the direction of the airflow, suspend the colored ball in the air, and slowly put the colored ball into the basket in front. After the fan is started for a period of time, the fan automatically shuts down when no one is involved.

Operate the knob to adjust the size of the airflow and the handle to control the direction of the airflow, and throw the colored balls from the launch port into the basket.
