In the steady chill of a household freezer, tiny frost crystals start to form on the inner walls. These delicate specks appear as clear ice, born from the brief rush of room air each time the door swings open.
That air carries moisture, which kisses the frigid surfaces and freezes in place. One crystal clings here, another there, too small to draw the eye.
Day after day, door openings repeat the process. Each brings fresh moisture that adds more crystals to the collection.
Quietly, the specks merge and layer. A thin white coating emerges across the back wall and shelves, thicker where the cold lingers longest. The buildup spreads evenly, speck by speck, without interrupting the freezer's hum.
Today, the frost rests there, a growing veil of ice crystals, steadily thickening in the enclosed frost.
