smoke ring

This exhibit presents a lively and interesting way for visitors to learn about Bernoulli's principle and related knowledge of eddy currents through interactive participation. The exhibit consists of a shaping platform, atomizer, pressing mechanism, and buttons. When visitors press the pressing mechanism on the booth according to the prompts, smoke rings will be sprayed out, bringing a unique visual experience and helping to intuitively understand relevant scientific knowledge. one Step into the exhibit and find the pressing mechanism 2 on the booth Press the pressing mechanism to observe the shape of the smoke emitted from the hole in the middle of the exhibit. The principle of smoke ring formation is that the annular vortex will confine the mist droplets in the annular area, thus forming a visible smoke ring, allowing the previously invisible fluid motion and vortex phenomenon to be visually presented through the smoke ring.

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.
