Zippering of flexible elements

 

The following movies show zippering of a flexible train of rods floating on a viscous liquid near a vertical wall. The self-assembling dynamics of the trains are the results of the capillary interaction between a wall and the train, and non-capillary interactions due to inextensible connection between the rods.
