Movie S2.

Deformation of cylinders made from poly(ethylene terepthalate) with different crease parameters and boundary conditions to demonstrate monostability and bistability. An isometric deformation of creased cylinder in absence of constrained boundary conditions can be seen. The antisymmetric deformation mode in case of a bistable creased cylinder is seen at 00:17 s .High-speed video accompanied for the snap-through transition @ 3,200 fps is included.
