There are furious droplets of clear liquid tumbling from the heavens, and I don't know what to make of it. I have a very faint recollection of a similar occurrence from my childhood, but I'm not sure if it had a positive outcome, therefore I am afraid to venture out.
For empirical research purposes I tossed an alien into it. Killed him. It was like acid. I may try the cat next, as a fellow member of the Class Mammalia may prove a better indicator of danger. I'm not sure the alien was even Phylum Chordata.
The grass sure seems to like it, though.
