'Medusa' shaped droplets containing liquid crystal molecules
Droplets containing chain-like liquid crystal molecules are spherical at high temperatures, according to findings by University of Pennsylvania researchers. If the chains inside the droplets are of varying lengths, they transform into "pollen," "flowers," "coral," and "Medusa" shapes when the temperature drops. "Medusas," pictured here, have long-reaching tendrils that contract back into a sphere when the temperature increases.
