    Lay a flashlight on the floor.

    In the horizontal beam of the flashlight, every mote of dust will cast a long shadow. Something as large as a tiny screw becomes easily visible.

      Anytime I’ve tried this I’ve ended up with the rim of the flashlight being larger than the item I’m looking for so I just end up going “wow this is a dirty floor” and turning it off to look with my eyes
