Non Newtonian Fluid

Note: I really HATE all the advertisements here but the info is good.

(fluid mechanics) A fluid whose flow behavior departs from that of a Newtonian fluid, so that the rate of shear is not proportional to the corresponding stress. Also known as non-Newtonian system.

CAVEAT! 
1) I have no control over the lettering superimposed over this video.
2) Let me be clear ~~~> I do NOT recommend any other videos by this young man. -- I include this one only because it is harmless and it demonstrates a simple science experiment that introduces non-Newtonian properties that are easily experienced. AGAIN, I do NOT recommend any of his other videos.

THESE I DO RECOMMEND:
•  Mythbusters Season 4 Disc 1 
• AND!!  Learn about the nature of fluids 

FLUIDS IN GENERAL!

Kitchens are full of fluids you might never have known were there. A fluid can be a liquid, gas, solid, or even plasma. 

Viscosity is a measure of the resistance of a fluid which is being deformed by either shear stress or tensile stress. In everyday terms (and for fluids only), viscosity is "thickness" or "internal friction". Thus, water is "thin", having a lower viscosity, while honey is "thick", having a higher viscosity. Put simply, the less viscous the fluid is, the greater its ease of movement (fluidity).^[1]
Viscosity describes a fluid's internal resistance to flow and may be thought of as a measure of fluid friction. For example, high-viscosity felsic magma will create a tall, steep stratovolcano, because it cannot flow far before it cools, while low-viscosity mafic lava will create a wide, shallow-sloped shield volcano. All real fluids (except superfluids) have some resistance to stress and therefore are viscous, but a fluid which has no resistance to shear stress is known as an ideal fluid or inviscid fluid.
The study of flowing matter is known as rheology, which includes viscosity and related concepts.
