Kekule's tail snake

This exhibit the process of Kekule's discovery of the benzene ring structure inspired by the dream of a tail snake through interactive experiences, highlighting the inspiration and contingency in scientific discoveries. The exhibits consist of a modeling platform, a rotating device, a handwheel transmission mechanism, a protective cover, etc. The core uses the principle of visual persistence to showcase the inspiration for the discovery of the benzene ring structure. Place double-sided plates on the platform, with a tail snake pattern painted on one side, symbolizing eternal circulation; The other side features a benzene ring pattern. When the device rotates, the tail snake and the benzene ring pattern will blend perfectly, intuitively interpreting Kekule's inspiration from his dreams and achieving an educational and entertaining science popularization effect. one Before arriving at the exhibit, locate the handwheel transmission mechanism and pay attention to the exhibit cover to ensure safe operation Rotate the handwheel and use the transmission mechanism to drive the double-sided disc on the platform to rotate 3 Observing the fusion effect of the tail snake and the benzene ring pattern on the double-sided disk during rotation, and feeling the inspiration for Kekule's discovery of the benzene ring structure. Kekule.

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.
