Newt, who was busy vaguely thinking about how much he wanted the lightbulb to stay stuck to the ceiling, grabbed the screwdriver without looking and jabbed it at a screw. Which was much too small, but that was okay, because he missed, accidentally jamming the screwdriver between the fixture and the ceiling.

"Er." He said, tugging on it. It wouldn't budge. "Bugger, hang on, I'll just-" he panted, leaning on it with all his weight.

A hairline crack started to creep away from the lightbulb.
