Okay kiddo, so have you ever played with slime before? Viscotherm is kind of like slime, but for grown-ups!
You know how some things are runny like water and some things are thick like honey? Viscotherm is a substance that can change from being runny to being thick, depending on how much force is applied to it. This quality is called viscosity.
Think of it like squeezing a toothpaste tube. When you squeeze the toothpaste tube really hard, the toothpaste comes out quickly because it's thin and runny. But when you don't squeeze the tube as hard, the toothpaste comes out slowly because it's thicker and more viscous.
Viscotherm is used in all sorts of things, like food processing, paint manufacturing, and even in making medicine. It's very useful because it helps to control the texture of the final product, depending on how much viscosity it needs.
So, in summary, viscotherm is like a special substance that can change its thickness depending on how much force is applied to it, kind of like how squeezing a toothpaste tube can change how easily the toothpaste comes out.
