In Wednesday’s Chemistry lab we worked with various polymers. Polymers are basically long chains of short molecules (mers) linked together. How the chains interact with each other determines physical properties of the polymer: strength, pliability, hardness, etc.  What you see in the photo are students drawing nylon from a beaker and wrapping it on a test tube. We also made two kinds of polyesters and compared them. Finally, no polymer lab is complete without making the classic cross-linked polymers of slime and silly putty.
