For our group’s polymer project, our open-ended design goal was to create something that relieves stress. However, there aren’t many new things that we can create with polymers. So, our group decided to make slime, and make it into a stress ball, but with eco-friendly materials. Our target audience is stressed teens, as teens tend to suffer from stress a lot, whether it is because of school or because of other reasons. We believe that helping teens to relieve stress is a very important part of our product, as it helps teens cope with mental stress. Currently, most slimes are made of PVA glue and borax solution. Despite the fact that they are the easiest products to get access to, they are not eco-friendly materials. We want to create a polymer slime that is eco-friendly, made of biodegradable ingredients. First of all, we want a base polymer that can act as a substitute for PVA glue. During our research, we found out that we can replace PVA glue with guar gum mixed with water. Guar gum is a biopolymer from a plant called the cluster bean (also known as the guar bean). When mixed with water, a thick, sticky substance is produced. Most importantly, guar gum is very eco-friendly as it is a natural material. We also replaced the borax solution with Tide detergent for the slime activator, as Tide is biodegradable. According to P&G, the company that created Tide, 95% of its newest detergent, Tide Purclean, is made up of biodegradable ingredients and water. Unfortunately, we are not able to find any Tide Purclean to use; therefore, we used regular Tide instead of Tide Purclean.
