Given that ocfnash's page never uses the term detonate, never discusses the difference between detonation and deflagration, and doesn't describe the experiments that would distinguish them, I'm pretty sure they were not in fact performed, and the (informal) explosion he witnessed was not a (formal) detonation.

That's not to say it isn't worth a footnote to explain that "doesn't detonate" does not mean "won't go pop and propel burning material everywhere." Even a campfire can do that, but I could understand if someone heard "doesn't detonate" and drew the wrong conclusion.
