So what does viscosity have to do with slime? Well, as a non-Newtonian liquid slime changes how it acts based on the forces applied to it. (Yep, peanut butter is a liquid.) If you try to drop it off a spoon it flows very slowly. If you pour it out of a container it flows pretty quickly. What is viscosity? Viscosity is a property of liquids that describes how fast the liquid flows. (Remember ooblecks? Those are non-Newtonian liquids too! Learn how to make them here!) Non-Newtonian liquids are liquids whose viscosity changes based on the forces applied to it. So what is it? Slime is a non-Newtonian liquid. Slime has characteristics of both solids and liquids. Volume stays consistent unless acted upon by outside forces. In a liquid, the particles can move around each other take the shape of the container they are in. They hold their shape and are, well, solid. These are things like tables, chairs, blocks. They are so tightly packed they don’t change shape unless acted upon by an outside force. In a solid, particles are tightly packed together. The big things we are going to look at are:įirst question: Is slime a solid or a liquid? It doesn’t act quite like water, but it doesn’t hold its shape like a block does. So what is slime? And how does it retain its sliminess? This is the science behind the sensory fun.
