The Science of Slime! It oozes between your fingers when you pick it up, yet doesn’t stick to your skin. At times it acts like a liquid, but at other times it appears to be a solid.
Slime flows like a liquid, but not like most liquids; its ability to flow, or viscosity, is not constant. So it's a fluid, but not a regular liquid. Scientists call a material that changes viscosity a non-Newtonian fluid.
What this means is, when you pour slime or let it ooze through your fingers, it has a low viscosity and flows like a thick liquid. When you squeeze a non-Newtonian slime or pound it with your fist, it feels hard, like a wet solid. This is because applying stress squeezes the particles in the slime together, making it hard for them to slide against each other.
Discover the science of slime during NCPL Avilla's SeptSTEMber Slime Programs.
