Unusual liquid crystal structures on water surface

Some liquid crystals form monolayers on water surface. When compressed from sides, such films of monomolecular thickness can wrinkle like fabric on a flat, smooth table, pulled together with palms simultaneously from both sides. With increasing surface pressure, the wrinkles of the monolayer fold up and form subsequent layers. New mechanisms of multilayer formation are responsible for creation of liquid crystal films with a structure that has never been observed before.
