It does go off easily when one tries to transport it.. which is why raw nitro is seldom transported. Dynamite was invented as a way to stabilize it and make it safer to handle and transport. When transporting nitro, they fill the bottles all the way, leaving no air in the bottle, because even a droplet splashing around inside the bottle can detonate it.

The TNT delay is on the order of 0.003 second. Fuzes using this full explosive-only TNT-type delay (base fuzes, for example, at the far end of the shell away from the target they hit) are called "non-delay" (they can have longer delays made inside the fuze, but that is not part of the explosive charge itself), as compared to "instantaneous" for nose impact fuzes ("Point Detonating" or "Direct Action") where the fuze firing shock on crushing against the target moves the blast sequence to the main explosive charge *backward* as the shell moves forward, so the shell center only moves a tiny amount forward as it is destroyed nose-to-base (as in those Dynamite pictures) even though that TNT delay happens there too.

2:55 The copper wasn't from the detonator. The copper was a cone with the widest end at the front, towards the target, and the narrow end, (where the actual detonator is), is to the rear. The explosive material is shaped around the copper cone, and when the device explodes, melts the copper into a plasma that burns through the target.
@Tunkkis2 жыл бұрын
There is no plasma involved, that is a myth. It doesn't go above a few hundred degrees C, IIRC. The enormous pressure just forces the liner material to act as if it was a fluid.

By that time, picric acid was not really being used any more as an explosive, more as a feedstock for making better ones.

Of course, if picric acid was used in the process somewhere (I don't know the TNT process offhand), then there might have been a route for contamination.

At circa 7:12 the Prof says the explosion occurred in the ammonium nitrate (AN) and TNT works. AN + TNT mixtures were used as shell fillers (" amatols"). Both the Allies & Germany used amatols to "extend" supplies of TNT. The problem with picric acid is that it forms extremely shock/friction sensitive salts with common metals such as Fe, Cu, Zn ... for which a small amount of the salt can detonate a large amount (such as the main charge in a cannon shell). Premature detonation in the barrels of artillery is bad for the soldiers. Guess what, munitions are commonly made of Fe, Cu, Zn, ...

detonator cap? So all the movies are wrong then when they blow up dynamite with a firework style fuse?
@yevrahhipstar39029 жыл бұрын
George Smith Two kinds of detonators; electrical (push the t-handle on the box) & pyrolitic; firework style. Both provide heat to an azide compound. Look up azides: they're great fun ;D
@zameliz9 жыл бұрын
George Smith Well the firework style ones just detonates a compound that explodes very easily with heat and that tiny explosion blows up the dynamite.

You cant make dynomite explode with a usual fuse as it doesnt produce any shockwave. You need a shockwave from another explosion to detonate the dynomite.
@ke6gwf5 жыл бұрын
No, they just didn't show that you push a detonator with the fuse crimped into it into the stick, as opposed to putting the fuse in directly. Now some may have had them tape the fuse to the outside or something, but if the fuse was sticking out the end, it was coming out of blasting cap/detonator.

@treahblade8 жыл бұрын
+Michael Jones Uhhhhh no incorrect here. Left over radioactive materials is not what fallout is..... its radioactive dust that gets picked up from the ground along with ash. It become radioactive due to the fission action occurring in the explosion.
@strongforce84668 жыл бұрын
+Michael Jones that's true, though thing about the thousands of nukes those degenerates detonated, in water, high atmosphere, underground etc.. that's massive pollution, plus every single atom is radioactive.. that's silly when you think about it 1 atom = 1 potential cancer or whatever autoimmune disease mutation etc ! think about the millions or billions of particles sprayed in the atmosphere, scary !

Near where I live (not far from Nottingham) is Fauld, where 3000 tonnes TNT equivalent exploded at an arms dump in 1944. The 120m deep crater is still visible on google maps, although the tags are all slightly out, the crater is in the wooded area just to the south. Its still fenced off as somewhere underneath are still thousands of tonnes of explosive.

2:55 - I may be about ten years late but presumably the traces of copper are not from the detonator casing but rather the copper liner which is compressed/directed by the shaped charge (The Munroe Effect) into a hypersonic fluid-like "jet" which causes the actual penetration.

I had a mathematics teacher in my first year if high school who had been a powder monkey in the mines of outback Australia in the 50s and he would tell us stories of using dynamite, gelignite, RDX and TNT to blow up things and how different explosives were used for different applications. Also he told us how one day when they had finished a job and they had some sticks of gelignite over and so during their lunch break they packed them into the base of a huge tree stump and let it off. The stump shot hundreds of meters in the air which was great..... until it came down and created a huge crater! Of course no one knew how had actually done it... of course!

Yiṣḥāq David It is a UK dessert, similar to a swiss roll (or jelly roll in the US) but filled with ice cream too. In fact it is just a tube of ice cream surrounded by a single turn of sponge and jam not a complete spiral to the middle like a swiss roll, which is probably what the chap was thinking of.

I'm not an expert, just an old Marine, but it's my understanding that dynamite is "close to" as stable as C4 as long as you haven't let it weep. I've burned C4 many times to heat up my coffee, but I gotta say, even I'd be a little nervous putting dynamite in a fire. There's a reason the military really doesn't use it anymore. Someone better qualified than me, may have a difference of opinion.

@loveslashdeath i think so too.based on what they said, and on the undergraduate chemistry I know, i think that only a small modification would be required to the formulation of the TNT stick such that some extra oxidizing agent would be required to both set off the explosion, and to help burn all of the TNT powerder.

The original dynamit was not a success. It was too weak and miners still used nitroglycerin. The real success was "rubber dynamite", which is a gel of nitrocellulose and nitroglycerin. Modern dynamite is mainly ammonium nitrate with some fuel, sensitized with some nitroglycerin or nitroglycol. In civil construction the explosives most frequently used is emulsion explosives, which are a mixture of an ammonium nitrate solution and fuel, sensitized by microspheres or similar. None of the components are themselves high explosives, and the resulting mixture is extremely insensitive to accidentalt detonation.

The penetration depth of a missile or shell before detonation is controlled by a delay fuse,not the time of initiation of the explosive.TNT has a VOD of approx 7000ms,which is virtually instantaneous.
