Screwed

I went rummaging through the shed today, looking for an odd screw to finish off a little job. It was a bit disconcerting to find this rusty mass in the box. I was a bit perplexed at first at what had happened to the contents.
After much investigating I had managed to find the cause, as a small hole in the shed roof which was allowing the rain to drip in, and so it would seem, directly into the container.
I did however, like the contrast between the plastic rawplugs and the screws and the way that only some of the contents were affected by rust.
