The movie shows a fluid in a rigid pipe which is connected to a hose of rubber-like material. A piston moves downward through the pipe thereby pushing the fluid into the hose which is sealed by a disc at the lower end. The hose bulges due to the increasing pressure until, finally, buckling into a state of lower energy occurs. The direction of the buckling is purely statistical.
The movie shows a fluid in a rigid pipe which is connected to a hose of rubber-like material. A piston moves towards the left through the pipe thereby pushing the fluid out of the hose. Gravity is accelerating the fluid downwards. The faster the piston moves the more the fluid streams towards the left instead of downwards.
The movie shows elastic toothbrush filaments which interact with a toothpaste consisting of a fluid and abrasive particles. The filament on the right is three times more stiff than the filament on the left which leads to less bending.
