Key Terms Defined
- Polymer
- Tiny molecules strung together in long, repeating chains
- Molecule
- The smallest part of a substance, it is made up of one or more atoms
White glue is loaded with long chain molecules that are called polymers. Borax links those polymers together into a big network; this is called cross-linking. The result is even larger polymers that create a thickened slime. The primary polymer in white school glue is called polyvinyl acetate.
Try this:
How does the texture of the slime change when you add less borax? More borax? Less glue? More water?
