The video shows a person's hand holding a stick and moving it back and forth. The stick is connected to a wooden structure with a gear on it. The gear is attached to a string that is tied to a wooden frame. The person moves the stick in a circular motion, causing the gear to rotate and the string to move back and forth. The wooden structure appears to be a simple machine, possibly a pulley or a lever. The colors in the video are mostly natural wood tones, with the gear being a light brown and the string being white. The background is a dark asphalt surface.
