Hi this fucked me up

my thesis involves this principle! in fluids, viscosity (the thickness/stickiness of the fluid) and inertia (the tendency of something to stay in motion when a force is exerted) are in competition. glycerin is incredibly viscous, so the viscosity beats the inertia and the dye doesn’t shift beyond where it is immediately pushed–so exerting an equal and opposite force on the dye just puts it back to its exactly original position.

It don’t mix, it just stretch.
