What the heck is this stuff?
D says: My mom, my sister, and I made two glow-in-the-dark gel balls. We used water, glue, glow powder (made from zinc sulfide), and borax solution. When we added the borax solution to the other substances it caused a chemical reaction that created a polymer. A polymer is a substance made up of a long strand of molecules. Some other polymers are silly putty, plastics, and rubber. The gel ball we made is not a liquid, solid, or a gas. So what is it? It is liquid trapped inside a solid - so it's both! This experiment was fun (especially when I pretended I had a giant booger).
