Two orange industrial robotic arms are positioned on opposite sides of a glass enclosure, each holding one end of a long, thin metal rod. The arms repeatedly pull the rod taut and then release it, causing the rod to snap back and forth in a rhythmic, elastic motion. The scene is set in a brightly lit indoor space, likely an exhibition or lab, with a white wall and a red and blue floor visible in the background.
