Ok Denise, be careful what you wish for, Girlie!
A fluid is a substance that continually deforms (flows) under an applied stress.
I think that definition refers to a sheer or force of some kind, yes?
A rock dropped from above into a pool of water would create that kind of scenario.
However, it goes without notice that the average human body is 60% water; a fluid.
I’m deforming as we speak.
