In the video, a person is seen using a credit card to create a rainbow on a white surface. The person has pink nail polish on their fingers and is using a credit card to swipe across the surface, leaving behind a rainbow of colors. The colors are bright and vibrant, and the rainbow appears to be made with a smooth, even stroke. The person's movements are deliberate and controlled, ensuring that the colors are evenly distributed across the surface. The video is shot in a well-lit room, and the white surface provides a stark contrast to the vivid colors of the rainbow.
