Craft glue is made up of molecules arranged in long chains that can slide past each other. Adding water helps the molecules slide more easily. When an activator is added, the boron it contains sticks the chains together, turning the mixture into strong, stretchy slime.
工艺胶是由排列成长链的分子组成的，它们可以相互滑动。加水有助于分子更容易滑动。当添加活化剂时，它所含的硼会将链粘在一起，将混合物变成结实、有弹性的黏液。

When placed in a container, slime spreads out slowly like a liquid to fill it, but in your hands it can be molded like a solid.
