In the video, a person is seen holding a small, pink and blue rubber band in their fingers. The person then uses a black marker to color the rubber band. The marker is applied to the rubber band in a circular motion, and the color gradually spreads across the surface of the band. The person continues to color the band until it is fully covered in black. The video provides a close-up view of the coloring process, allowing viewers to see the details of the coloring technique.
