Ultra-realistic PCR laboratory interior shown fully, filled with extremely tiny miniature human figures, many of them living between the pipettes, tubes, and thermal cyclers, doing everyday activities like hanging laundry on racks of pipette tips, carrying small buckets across microtubes, sitting, talking, cooking on a hotplate, walking along benchtops. The scene feels like a hidden miniature town inside the lab. Subtle comic touches, like one person slipping slightly on a droplet or a small group laughing near the centrifuge. Natural lighting, with a few warm little lights installed among racks and machines to make it feel inhabited. Clean, realistic lab textures, no text or signs anywhere, no labels, no writing. Equipment layout is natural and freeform. Cozy and warm everyday mood, cinematic realism, hyper-detailed, 4K quality, 9:16 vertical composition,
