In the video, a person is seen holding a clear glass bottle in one hand and a bottle of paint in the other. The person proceeds to pour the paint into the bottle, filling it up with the color. The person then uses a brush to spread the paint around the inside of the bottle, ensuring that the entire surface is covered. The paint appears to be a light blue color, and the person seems to be applying it carefully to avoid any drips or spills. The background is a plain white surface, and there are no other objects or people visible in the video.
