air cannon

This exhibit the Bernoulli principle, compressed air principle, and their power through interactive experiences. Set up a set of air cannons for the exhibit, equipped with drum surfaces, hanging sequins, and other devices. visitors tapping the drum surface can generate a flowing airflow (air cannon), which can blow the sequins hanging on the top; Children can intuitively feel the charm of air energy by adjusting the impact force and comparing the airflow intensity generated by air cannons of different strengths. one Entering the exhibit, first read the operating instructions to understand the interactive methods and precautions of the exhibit Aim at the hanging sequins on the top, tap the drum surface with your hand, and observe the changes in the movement of the sequins under the action of air flow. The relationship between force and air flow intensity: the force of tapping the drum surface is different, and the degree of compressed air is also different - the greater the force, the stronger the high pressure generated by compressed air, and the faster and stronger the air flow formed after release, the greater the corresponding movement amplitude of the sequins, achieving a visual correspondence between force and air flow intensity.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.
