large-scale Newton's cradle in front of a store window

large-scale Newton's cradle in front of a store window. The cradle consists of approximately ten metal spheres suspended by strings from a horizontal bar. The store window displays mannequins wearing clothing. A person walks across the screen from left to right in front of the Newton's cradle, and a voice is heard in the background. The ground is made of wooden planks. The video is shot from a stationary position.
