Researchers have created dynamic structures that leap into the air on a predetermined schedule without intervention from computers or external stimuli. Precisely when these “metashells” jump, and how high they jump, is engineered into the physical structure of the materials. This image combines time-lapsed photos to show one of these "metashells" leaping into the air from a snowy surface.
