Non-Newtonian Fluid

I was an adult when I learned of a Non-Newtonian fluid. Do you know what they are?  Or even what a Netownian fluid is?

Growing up I do not remember this ever coming up while I was in school.  What are they? Defined by Merriam-Webster Dictionary a Newtonian fluid is a fluid whose viscosity does not change with rate of flow. Huh? Basically no matter how fast or slow it’s going the resistance to flow; it follows all of Newtons laws on how liquids should act.

Then what is a non-Newtonian fluid? According to Science Learning Hub it is defined as fluids  that change their viscosity or flow behavior under stress. If you apply a force to such fluids (say you hit, shake or jump on them), the sudden application of stress can cause them to get thicker and act like a solid, or in some cases it results in the opposite behavior and they may get runnier than they were before. Remove the stress (let them sit still or only move them slowly) and they will return to their earlier state.  Think of slime or cornstarch and water.  They can ooze around and take the shape of any container they are placed in but still act like a solid under situations.

Why does any of this matter? Because I feel like a non-Newtonian fluid.  Many people have heard me say ” I am like water, what do you need?”  Yup I am really good at morphing into just about any roll, some better than others. Please do not take my ability to transfer my position/roll to fit the situations needs.  I have adapted well to many scenarios and truth be told I am at my breaking point.

I am being pulled in so many directions like to many kids pulling on silly putty to see how far it can stretch, there is not much left to hold me together.  This does not mean I am brittle and about to break, on the contrary, we non-Newtonian fluids fold back together after being broken, unlike Newtonian fluids.  We are more versatile and can make a lot happen.

Now the question is, in what shape and form will I take next?
