This movie shows what happens when you inject a gas into a granular suspension at different injection rates. At low rates, "stick slip" bubbles emerge, followed by "temporal intermittency" where periods of continuous motion are interrupted by occasional jamming. Increasing the injection rate further produces a spectacular "coral"-like pattern, and ultimately destabilized viscous fingers appear at high rates. http://folk.ntnu.no/bjornas/
Your time-lapse films are fascinating !
