In the video, a person is seen holding a laser pointer in a dark room. The laser pointer is turned on, and the person points it towards a wall. The laser light is bright green and creates a small circle on the wall. The person then moves the laser pointer around, creating different patterns on the wall. The light is intense and vibrant, and the patterns change as the person moves the laser pointer. The room is otherwise dark, and the laser light is the only source of illumination.
