One of the most interesting facts about striped toothpaste is that these stripes don’t mix while they are in the tube. Have you ever wondered why toothpaste stripes don’t mix? Well, toothpaste is known as a non-Newtonian fluid. It does not act like a regular fluid or a regular solid.
It’s viscosity and density make it act like a solid material unless a shear force is applied on it. So, when the toothpaste stays in the tube, it acts like a solid and we all know that the molecules of solid materials don’t mix together.
But, when you take the toothpaste out of the tube and brush your teeth with it, the shear force applied on it causes it to act like a liquid and the colors mix together.
In this article, we will dig deep into the causes behind toothpaste stripes staying separate. Let’s begin.
