Answer #1

Slime is a flexible material made up of polyvinyl alcohol polymers that are held (or cross linked) together. In the first beaker we have a polyvinyl alcohol solution where long chains are floating around that look like this:


The weak hydrogen bonds break and reform continuously while the slime is being stretched. If it is pulled too quickly they don’t have time to reform.

so when  slime is pulled quickly it breaks, but when it is pulled slowly it stretches.
