This video is making the rounds on the Internet.  I don’t know anything about Bob Naman, but he knows more about the subject than I do, and so far I haven’t found any rebuttal online.  Nor do I know anything about Project Gulf Impact.  If anybody has any information, please post it.

A little more on his testing (with a TV 5 video).  It exploded.  I’m pretty sure that water shouldn’t explode.
