What kind of stuff does it take to make a volcano throw up?
I guess if it's a young volcano -- say about college age ... I probably know the answer.
By the way, I know another answer too. If this stuff gets out of hand ... "antibodies!" (I got that one from Jim Kirk.)
Just gave myself a shiver remembering some line from the Bible..."And a third of the seas turned to blood..." or some such.
Surpassing wierd. Fortean.
Hope it's harmless. ;-D
