Gel undergoes Peristalsis

(PhysOrg.com) -- Large or small, machine parts only move when controlled by an external impulse. Biological systems, on the other hand, are capable of autonomous movements that continuously follow their own rhythms and spatial patterns. For example, intestinal peristalsis—a circular, constricting, unidirectional muscular contraction—depends in part on an inherent muscular rhythm.
