The Science Behind Slime
Have you wondered how a few ingredients mixture can end up with a gooey slime?
Well, it is all about science!
When the borax from the contact lens cleaning solution mix with the polyvinyl acetate from the glue, it forms stretchy substances through a process called cross-linking.
Glue is made of long and identical molecule chains. These molecules keep the glue in a liquid state as they can slide past one another easily.
Then, when you introduce borax to the glue, each of the molecules starts to tangle and the liquid loses its form. It becomes more difficult for the molecules to pass each other easily.
Eventually, the mixture tends to get thicker and more rubberier. And when it does, it is time to play!
