Wonder who the proud soul was who fired the first hand cannon

Actually the first occurrence of gunpowder may have been at the Dead Sea area where a combination sulfur, coal and potash were mixed together by an earthquake and set off by earthquake lights not exactly regular lightning. That was the teaching 60 years ago. Now they have progressed to a meteorite with their teaching. Either way they got fire and brimstone as a result.

I've never read any info about a rainbow associated with the event either, lol.
