The video starts with a view of the Earth from space, then zooms in to show the planet's surface. The Earth is then shown with a cross-section cut out, revealing its layers. The video then focuses on the core of the Earth, where a pink ball appears, representing the proton. The pink ball then splits into smaller balls, representing the neutrons, which are shown orbiting around the proton. The video ends with a close-up of the neutrons orbiting the proton.
