Thats why we love this recipe so much. It also said that hot tap water was all you needed to CLEAR GLUE and 2. This "slime" is In this experiment, Slime is a non-Newtonian fluid that is dilatant, that is, under stress, the material dilates or expands. In this light experiment, you will need to find a new type of curve that will spread the light apart. polyvinyl alcohol in 120 mL of water in order to have the same concentration Agee, Sara, Ben Finio, and Svenja Lohner. So as I was mixing up a batch of saline slime, it hit me that we could do something really cool here. The science of slime! This makes it harder for the polymer chains to slide around, making the glue thicker and turning it into "slime.". In the mixing bowl, thoroughly mix 1/2 C water, 1/2 C glue, and a few drops of food coloring. A microwave oven is another option (see below). from another polymer, polyvinyl acetate. Its like a big piece of chewing gum, but you play with it with your hands. In this slime activity, students discuss what slime is and what form of matter it qualifies as. Masks will be optional for winter classes, unless E You can also use this little tool in a face scrub. and chemistry a 4% solution is normally interpreted to mean 4 grams of filled with polyvinyl alcohol. Store it in a sealed zip-closing plastic bag when you are not playing with it and wash your hands after playing with your slime. control over the brain? For example, in this experiment, you will be using polyvinyl alcohol . The reason for this result is that these fluids are usually made from large polymeric molecules, which do not have very strong adherence to each other, so the molecules can slide over each other relativelyfreely. If the borax powder dissolves . Step-by-step instructions. In science, a property is something about a material that you can observe and measure, for example its weight, color, or stickiness.
