Upward Rain on Thermostat Kit in Frankfurt Room

Pale dawn light slips across dusty laminate floors in a Frankfurt mechanical room, illuminating a thermostat commissioning kit arranged among cardboard tubes, steel tools, and plastic guards. Condensation beads on nearby glass surfaces, marking the chill of early winter. Crisp silver streaks of rain fall upward from the floorboards, defying gravity while the cardboard tubes and steel tools remain grounded and still. The metallic surfaces reflect the upward-moving water droplets, creating a stark contrast between the mundane construction materials and the impossible weather event. Dust motes hang suspended in the pale light near the rising rain, showing the stillness of the tools against the vertical motion. at the edge is a single droplet clinging to the edge of a plastic guard, mirroring the upward flow.
