what is slime?
Slime is a unique play material composed of a cross-linked polymer. It is classified as a liquid and is typically made by combining polyvinyl alcohol solutions with borate ions in a large mixing container. It often has an unpleasant odor, a green color, and is cold and slimy to the touch. In scientific terms, slime is classified as a non-Newtonian fluid. These are thick liquids that have a variable viscosity. Viscosity is a measurement of the resistance to flow when a shearing force is applied. Newtonian fluids have a constant viscosity depending on their composition.
