The video shows a close-up of a Lego creation. The Lego creation has a green arm that moves back and forth. The arm is attached to a black string that is being pulled by a person's hand. The background is blurred, but it appears to be a table with other Lego pieces on it. The Lego creation is made up of various colored blocks, including green, yellow, and blue. The arm moves smoothly and appears to be made of a flexible material. The person's hand is only partially visible, and they are wearing a black shirt.
