Maggie’s Socially UNacceptable Humor

I remember something that turned your teeth red, but that was the early 60s.

If it’s any consolation, he is in a world of hurt right now. I accidentally ( not arson😁) lit my hands on fire just like that dude did. Pouring gas in a carburetor and it back fired. Spent 11 days in the burn unit and had grafts on my hands. Took months of PT to get full use back. Worst pain by a factor of ten over anything I’ve ever experienced.

Screen name checks out.
 
That was a bit more volatile than fireworks.
1 solid detonation usually means 1 explosive component.
I'm not one to speculate but a random shot in the dark would be sweaty dynamite sticks or something similar.

Seems a bad way to transport dynamite as well.

Incidentally in the old days when dynamite was transported via wagon, it was discovered that people who came into contact with leaky nitro glycerin developed head aches and low blood pressure.

A non explosive form is used in medicine today.

Could be metallic flash powder used for firecrackers and dynamite initiators. Flash powder undergoes deflagration just like black powder, but at such a fast rate that it would appear like a detonation to naked human senses without precision scientific tools to observe the ignition sequence. If that box had been a detonation as in plastic explosives or ANFO, the supersonic blast wave and vacuum right behind it would have obliterated everything, including the camera.

Magnesium based flash with perchlorate oxidizers are extremely sensitive and could ignite from impact or static electricity. A far more stable form would be aluminum with KNO3 and sulfur as a binder. When I was much younger in China we made stick grenades with AL flash as the main compound, metal heads crafted from capped pipe ends and complete with pull fuses made from strike anywhere matches. Wicked things. Flung shrapnel everywhere that embedded into trees. It would still suck to be anyone in that video after that box went off.

Still gives you a headache...according to my dad and my brother.
 
When you were the young punk in the mines and complained of a powder headache the old timers would often tell you to rub just a tiny bit inside the band of your hardhat and it would help.

Yes, I was a young punk. Yes, I did it. Yes it helped .. the headache. Felt like my head was going to explode. Made through the rest of the shift, showered and made it home. One of the worst nights I've spent. I didn't continue the tradition.

Apache powder was the worst. NG based powder is virtually nonexistent now days for commercial use because of this and some other reasons.


As to the Chinese fireworks explosion video. Blue Sky is pretty much right on. If the flash powder escapes its container and gets pinched between two relatively solid objects a jarring impact or a scrub can provide the energy required for initiation. Gets worse from there. Remember the "Pop-Its" or "Pop Rocks" we played with as a kid. I quit fireworks 40 years ago.

Thank you,

Yeah.
They tell you to wear gloves when applying NTG paste.

First thing you do is save a bit and put it on your hand, just to see what it feels like.
The joys of being 19 and smart. 🤣

Yeah, I remember turning the sticks every six weeks. Fortunately, an older guy warned me.

A few months ago the ER applied a patch to bring my BP down from 229/112. I don't recall a headache...but I had so much going on maybe I just didn't notice.
