What is a good popular science video?

Why do popular science videos such as How to Take the High Speed Rail explode? Because of the short video of popular science, the knowledge of "high cold" is more fun. Compared with the traditional graphic form, short video has four characteristics: immediacy of knowledge dissemination, personalization of knowledge presentation, manifestation of tacit knowledge and popularization of complex knowledge. Experts say that short videos can condense knowledge points and convey them to the audience in a more vivid way, which is lively, interesting and interactive, changing the appearance that knowledge is difficult to understand and boring, and narrowing the distance between the public and scientific knowledge.

How to make knowledge analysis interesting? It is not easy to realize. "Let abstract science be grounded" and "Let more people know that popular science is closely related to life" is a major reason for the explosion of popular science videos. Compared with the traditional scientific explanation, the scientific principle is presented by a realistic model made by hand, which "endows the lens with physical objects to let the audience clearly perceive the details". These short videos are easy to understand and interesting.

"If the popular science video is too profound or obscure, it will not achieve the effect of popular science and lose its meaning." In my opinion, "a successful popular science video can be understood by primary school students and interesting for adults."
