The action begins when a tray is filled with measured amounts of water and slid into the freezer compartment of a household refrigerator.
For the initial period following placement, the water exhibits no visible change. It remains a clear liquid, undisturbed in each compartment of the tray, identical to its state moments before entering the cold space.
Minutes turn into hours as the tray rests quietly. The surface of the water stays smooth and reflective, with no alteration detectable by sight. The surrounding frost on freezer walls may accumulate, but the water itself shows continuity in appearance.
Eventually, when the tray is inspected again, the contents have solidified. Each section now contains a distinct ice cube, opaque and rigid, marking the point where the outcome becomes observable.
The interval between placing the water in the freezer and observing the frozen cubes illustrates latency: the cause is set, yet the visible result emerges only after a delay.
