The video tutorial demonstrates how water moves up through a plant's stem using two methods. Method A involves placing a balsam twig in red inked water, showing red lines in the stem, leaves, and flowers after 8-10 hours. This indicates water movement through the stem. Method B uses two beakers with red and blue ink, showing color movement in split twigs, indicating water and mineral transport through stem tubes to other plant parts.
