Porous Artificial Rock Helps Channel an Answer to a 54-Year-Old Mystery

Caption

Video showing the movement of a polymer solution inside a pore due to a flow imposed from left to right. Bright streaks show the motion of small tracer particles; dark circles at the periphery show the 0.3 mm-diameter solid grains comprising the solid matrix. At this higher flow rate, polymers cause the fluid motion to become chaotic, with swirling eddies that form, grow, move, and disappear, as well as considerable fluid mixing.
