Imagine a candle freshly lit on a tabletop during an evening meal. The wick draws up wax evenly, producing a tall, steady flame that spreads warm light across the nearby surfaces.
The glow covers a wide circle, keeping shadows at bay around plates and chairs. The candle stands full height, with a smooth top.
Over time, the flame consumes the wax bit by bit. A small pool forms at the base of the wick, and the overall height begins to drop.
As the candle shortens, the flame dips lower toward the table. The light gathers more closely around the base, dimming the outer areas. The wax pool grows wider, causing the flame to sway gently.
The broad illumination shifts to a tighter, less steady pool of light. What began as a consistent glow ends with a small, flickering presence before it goes out entirely. The tabletop setup reveals its changing nature through these visible shifts.
