#FunFact Non-Newtonian Fluids
We shall start from the basic concept of viscosity: it is the measure of how well a fluid flows.
For example water flows quite well and it it less viscous than peanut butter, since the latter flows significantly less.
It is something measurable, but the details will not be explored here, what is important is that Newton's law of viscosity states that it is a value that independent of shear stress, that is to say having parts moving at different speeds.
Non-newtonian fluids do not follow this law (which is rather a law that follows from observation rather than a necessity).
The three main categories are fluids that become more viscous with stress, less viscous with stress and "solids" that become viscous with stress.
Of the first two there are two sub categories: immediately changing and changing depending on the time.
Shear thickening fluids
The most prominent and known example of non newtonian fluid is the oobleck (a mixture of corn starch and water), which can flow freely but if it is interacted with with force it thickens. You could, for example pour it but also, with enough force, knead it like dough.
Rheopectic fluid
There aren't many fluids that thickens with time of stress that can be encountered daily. Synovial fluid, that is the lubricant in the joints, is an example of this kind of fluid.
Shear thinning fluids
Common examples of this are quicksand and blood.
Thixotropic
An example of fluid that become thinner with stress over time is yogurt.
Bingham plastic
These are fluids that need a certain amount of stress before being able to flow, one common example being toothpaste.

hey, synovial fluid is there
fun fact about synovial fluid (may or may not be 100% scientifically accurate, since i was explained to a bunch of years ago):
sometimes, the "bag" which contains that fluid in your joints breaks, and the weird fluid gets out. once its out, usually it gets reabsorbed by the body, the bag gets autofixed, and you generate more fluid, because the human body is a perfect machine. some times, tho, it can decide to solidify in whatever form and not be reabsorbed. ask me how i know.

also, directly from wikipedia (because i opened the link just to make sure that i wasnt mixing things, tho i havent really read it), " Synovial fluid is an ultrafiltrate from plasma, and contains proteins derived from the blood plasma and proteins that are produced by cells within the joint tissues.[4] "
this (in a pseudoscience way at least) would confirm my theory/statement that when you are losing blood every day and/or anemic, your knees hurt substantially more, which i have had for many years now
