Apex Fire II:

Under the category, "funny if not kinda sad", a barrel of sodium metal burst into flames yesterday after the water reactive substance was allowed to sit out in the rain. This has slowed down the cleanup.

Thanks to the good folks at: http://www.jtbaker.com here's the lowdown on our friend sodium metal:

SAF-T-DATA(tm) Ratings (Provided here for your convenience)

Contact Rating: 4 - Extreme (Corrosive)

Not something you want to ingest. "Will react immediately with saliva to cause serious burns and possible local combustion and even explosion of hydrogen in the mouth or esophagus." I checked ... this is not how Pop Rocks works. Interestingly, according to snopes.com, General Foods had to conduct a major PR campaign in 1979 to assure a worried public that you could not blow up from mixing Pop Rocks and soda.

I'll bet Krusty Brand Boom Rocks © uses the sodium metal.

Here's a picture of APD & I post-toxics inhalation. They say the antennae will fall off in a few weeks.
