What happens when you stretch your slime?
What happens when you squeeze it?
What happens if you roll it into a ball and bounce it?
Why do you think glue is important in this mixture? (Hint: Glue is made from long, thin, chain-like molecules called polymers. What do you know about crosslinking polymers?
Crossing makes the glue and slime thicker.
