The video uses a roll of toilet paper to illustrate how objects can be perceived differently based on viewing angles. This concept is applied to astronomy, where objects like quasars and blazars are named differently depending on the angle from which they are observed. Quasars are viewed at an angle, while blazars are seen head-on, leading to different appearances and behaviors. The video explains the scientific significance of these differences and concludes by encouraging viewer interaction.
