The video shows a 3D model of a blue cylindrical object with two smaller blue cylindrical objects and a green circular object. The larger cylindrical object has a cutout on one side and a small green object is placed inside it. The smaller cylindrical objects are placed on either side of the larger object. The video shows the green object being moved around inside the larger object, and the smaller objects being moved around the larger object. The video ends with the green object being removed from the larger object.
