Non-Newtonian fluid is a mysterious and special type of fluid and does not conform to Newton's law of viscosity. This means that when a non-Newtonian fluid is subjected to a force, such as striking, impact, or stepping, its viscosity changes. Sometimes, this change makes the fluid easier to flow, while at other times, it becomes as hard as a solid. Students made non-Newtonian fluids using starch, experiencing its viscosity changes, while having fun and understanding the scientific principles behind it.
非牛顿流体,一种神奇且特殊的流体,它并不满足牛顿黏性实验定律。这意味着当非牛顿流体受到某种外力时,比如击打、撞击或者踩踏,其粘度会发生改变。有时,这种改变会使得流体变得更加容易流动,而有时又会变得像固体一样坚硬。学生们使用淀粉制作非牛顿流体,在玩乐的同时,切身感受其粘度的变化以及背后所蕴含的科学原理。
