用容器倒水时，水流会顺着容器外壁流下，造成这种现象的原理称为“茶壶效应”.该现象贴近生活且有较为直观的物理内涵，物理学家对“茶壶效应”的成因进行了深入研究并完成了很多工业设计，但相关原理尚未融入现有教学体系，形成实验教学内容.“茶壶效应”实验是为该原理开发的实验和相关教具.该实验操作简单，演示效果直观，丰富了物理实验的教学资源.

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.
