[0002] The ways of science popularization are constantly innovating with the development of the times. From traditional science popularization books, lectures, documentaries, to diversified communication channels such as offline science and technology exhibitions, science popularization education and training, etc., are building an ecological system of "all-region science popularization". Among them, physical science popularization devices, as concrete and experiential science popularization carriers, have irreplaceable value.

[0003] At present, the construction of basic education facilities in China is booming, but science popularization education devices targeting physics and chemistry disciplines have not received much attention. The main reason is that the development of outdoor science popularization devices is relatively lagging behind, there are no ready-made products available, and thus they cannot enter the construction stage. Therefore, developing outdoor physics science popularization devices is of great significance for improving the physical knowledge level of the public and strengthening science popularization education.
