In the video, a person is seen kneading a large ball of blue slime. The slime is bright blue in color and has a sticky texture. The person's hands are covered in the slime as they press and fold it, creating various shapes and patterns. The slime appears to be soft and malleable, stretching easily as the person manipulates it. The background is a plain white surface, which contrasts with the vibrant blue color of the slime.
