In the video, a person is seen pouring chocolate over a tray of marshmallows. The tray is covered with aluminum foil, and the marshmallows are arranged neatly in rows. The chocolate is being poured from a large pot, and it flows smoothly over the marshmallows, covering them completely. The chocolate is a rich, dark brown color, and the marshmallows are white and fluffy. As the chocolate is poured, it begins to harden, creating a glossy coating over the marshmallows. The person pouring the chocolate is careful to ensure that each marshmallow is evenly coated.
