Fine times with homemade slime (or silly putty if we tweak it up a bit) At some point you may have heard someone speak of “polymers”. A polymer is a large molecule that is made of repeating structural units. These units are connected by what is called a covalent chemical bond. A well known polymer is “plastic”. In this experiment, we will make a polymer and then add a substance that will cause the polymer chains to cross link. Cross links are bonds that link one polymer chain to another. When the polymer chains are more “bound together”, they become harder to move around and begin to gel. In a bowl, mix an equal quantity of Elmer’s glue and water. Fill a jar with a…
