Yup, Tannerite will detonate from a bullet strike. I have a 5 gal bucket of nitrate I picked up from a fertilizer spill but its so damn humid here I'd have to invest in a vacuum desiccator to ever dry it.




Why did i wait so long to by a hotplate stirrer?

On arrest, his first words were; "Fuck, I suppose this means Trump's going to stiff me, too"?

Yup, Tannerite will detonate from a bullet strike.

Yeah, but not from a "Christmas light", or from being hit by a car, even one traveling over 300 mph.
I'm surprised to hear that "a half assed cap will do", but then I have next-to-no EM experience.

Christmas lights make good, improvised ignitors!

So you're saying a glowing wire is all it takes to set off Tannerite? That contradicts most of what I've read.

Edit:
While researching this further, I discovered a New York Times correspondent claiming the bombs were in fact made with HMTD.

Not nececcelery ─ and I didn't mention tannerite?

It will certainly, though, fire an improvised detonator!

My mistake. As your comment lacked any other context, I thought you were responding to my comment about the inability of such things as the filament of a Christmas light or a subsonic impact to reliably initiate Tannerite specifically. I agree that an incandescent light bulb filament could initiate a sensitive primary which could then set off a less-sensitive secondary, like Tannerite.

Would the pressure cooker confine the AN/Al mixture effectively enough that it would transition to detonation after being ignited? Or would there have to be a primary involved?

Interesting, I had never heard of Ned Kelly. I always assumed that your username was a Game of Thrones reference.

AN/Al will not even sustain combustion let alone undergo DDT. It requires a detonator.

is that what people have been thinking about me? a grown man who has named his user profile after Game of Thrones? I wasn't even aware because I've never watched it, I don't even know if it's a television show or a movie

Haha, it's a show on HBO, and a very good one. Personally I don't think it reflects badly on you at all, but I'm biased since I like the show.

[spoiler] There's a prominent character named Ned who gets beheaded at the end of season one and it was kind of a big deal.

well that"s a relief,

even fictional Ned's have a hard time keeping their heads on their shoulders

Edit: it also explains why the user name "Ned'sHead" (with the apostrophe) was taken, I couldn't imagine why anyone else would want that user name

Boom.
The explosion removed the windows, the door and most of the chimney.
It was the sort of thing you expected in the Street of alchemists. The neighbors preferred explosions, which were at least identifiable and soon over. They were better than the smells, which crept up on you.
-Terry Pratchett, "Moving Pictures"

It is essential that persons having explosive 
substances under their charge should never 
lose sight of the conviction that, preventive 
measures should always be prescribed 
on the hypothesis of an explosion.

All secondaries need a primary to set off, and higher powered primaries need a initiator such as heat spark of friction.

It is called an explosive train, so one can use a bit of wire and a match for the start of the train, then HMTD/TATP/lead azid, mercury fulimate and so on.

This then leads to the booster, this can be a mixture of a primary and secondary, or a fairly sensitive secondary.

Then your main bursting charge, but in the case of a sensitized explosive such as Am/Al One can use a simpler train with just two stages at the cost of slight higher chance of failure.

Thank fully the ones building these devices tend not to be the smartest to begin with! In the technical arts.

Conversely, most people smart enough to build and deploy complex devices are also smart enough to know that doing so would be a horrible idea. However, one can cause plenty of terror with quite primitive methods (like a big truck moving very fast).



As below, so above.
