The video shows a close-up of a blue plastic funnel with a hole in the center. The funnel is placed on a surface and water is being poured into it, creating a vortex. The water swirls around the hole, creating a mesmerizing effect. The video captures the movement of the water as it flows through the funnel, highlighting the physics of fluid dynamics. The blue color of the funnel contrasts with the clear water, making the vortex effect more visible. The video is shot in a way that focuses on the movement of the water, providing a detailed view of the vortex and the flow of the water.
