Seaside Adventure - Octopus Splashing Water

This exhibit aims to provide interactive experiences for visitors to understand the principles and knowledge related to Coriolis force, and cultivate their interest in exploring scientific mysteries. The exhibits mainly consist of octopus shapes, handwheel devices, shape bases, encoders, and water pumps. The core interactive structure is a set of octopus water spray devices set up at the edge of the pool. visitors can control the rotation of the octopus model by turning the handwheel, and at the same time, its 8 claws will start spraying water; It can be observed that the outward water flow lags behind the direction of rotation, while the inward water flow leads the direction of rotation. After stable rotation, a picture of the interweaving of the inside and outside of the water flow is formed, allowing visitors to observe the peculiar phenomenon produced by the Coriolis force and preliminarily realize that objects moving on the rotating system will be subjected to an "invisible" force. one Shake the handwheel device to start the rotation of the octopus model, and observe the phenomenon of its 8 claws synchronously spraying water Maintain stable rotation of the handwheel, wait for the water flow to stabilize, and enjoy the unique scene of the interweaving inside and outside of the water flow.

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.
