In the video, a person is holding a chain of magnetic balls in their hand. The chain is made up of small, round, metallic balls that are connected together. The person then places the chain on a wooden surface and begins to move it back and forth, demonstrating the magnetic properties of the balls. The balls stick together and move in a straight line, following the direction of the person's hand. The wooden surface provides a contrasting background that highlights the shiny, metallic color of the magnetic balls. The video is shot in close-up, focusing on the chain and the person's hand, and the lighting is bright, making the details of the chain and the wooden surface clearly visible.
