Pouring water with a container, the water flows down the outer wall of the container, resulting in this phenomenon is called the principle of the “Teapot effect”. The phenomenon is close to life and has a more intuitive physical connotation, physicists have conducted indepth research on the causes of the “Teapot effect” and completed a lot of industrial design, but the relevant principles have not been integrated into the existing teaching system, forming the experimental teaching content. The "teapot effect" experiment is an experiment and related teaching aids developed for this principle. The operation and effect of the experiment are simple and intuitive. This experiment enriches the teaching resources of physics experiment.
