The moon might even now be sculpted by plasma streamers originating in the solar wind, or even launched all the way from the earth's upper atmosphere, or from the sun. He was working with a large hi-volt power supply, and kept getting oil on his glasses and on his face for no apparent reason. Finally he noticed some strange lines in the air, almost like spider webs, which could only be seen against a dark background.

But in addition, these streams of micro-droplets formed themselves into thin channels which traveled over long distances.
