In the video, a person is seen holding a piece of blue chalk in their hand. The person then proceeds to rub the chalk against a white surface, which appears to be a piece of paper or a board. As the person rubs the chalk, small pieces of chalk dust can be seen falling onto the surface. The person continues to rub the chalk in a back and forth motion, creating more dust. The video provides a close-up view of the action, allowing the viewer to see the texture of the chalk and the dust particles.
