[@VRossInMo]

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.

This explains why in those old Crash Bandicoot games the nitroglyceryn crates explode instantly while the TNT crates have a short delay.

[@minxythemerciless]

@@longimanusisurus132 The oxygen balance doesn't seem to be a major factor in effectiveness of TNT for high bruisant purposes.

I worked with dynamite [ok, played with it!] years ago, and I can tell you there is no headache worse than a nitroglycerine withdrawal headache! Those dilated veins and capillaries [I hear this as 'cap-pillories' and not the American cap-pill-airies. Thanks BBC!] draw tight when the nitro runs out! Think deep 'brain-freeze' pain for about three days! This is why you carry nitro 'samples' home!

[@patrikmanni3559]

+Steve Johnson You DO get withdrawal effects after long term nitroglycerin exposure since your body adjusts for the vasodilation. When you stop using it after building a tolerance you suffer from vasoconstriction and the pains associated. Medical administration of nitroglycerin includes gradual dose reduction procedures because of this.

[@patrikmanni3559]

***** Vasoconstriction is quite literally the cause of headaches. Nitroglycerin withdrawals do cause headaches. And it would depend entirely on how much the person was playing with nitroglycerin, what the methods of exposure were, and on the individual in question.

[@lensman3a]

there's a slight mistake in this vid. TNT does not have enough oxygen to burn all the carbon even to the monoxide form. That's why ammonium nitrate is sometimes needed to increase the oxygen and hence the energy

Thee bright-yellow color of skin of "Canary girls of Chilwell", most probably, was because not of TNT, but of "Lyddite" (picric acid, trinitrophenol, TNP).

[@U014B]

I thought Lyddites were those guys that hate technology.

[@davidhorsley1149]

Wasn't going to weigh in but in both nitroglycerin and TNT manufacture there is a second step that imparts a yellow hue to the final product. That yellow color is readily absorbed into porous material including skin.

[@jodybanks5344]

[@geodeaholicm4889]

another early use for both nitroglycerine and shaped charges was in oil wells; tubes of nitro were set off inside early oil wells to frack them & release more oil from the formation. shaped charges are still used today to perforate the steel casings to allow oil & gas to flow into the wellbore.

[@nathanokun8801]

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.

[@steztoyz]

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.

[@Tunkkis]

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.

Wasn`t it picric acid (Trinitrophenol) that was being loaded in the shells by the women? It is also used as a Dye and is canary yellow.

[@proffski]

Correct! It was also called Lyddite, see my posting above. This needs correcting.

[@Tindometari]

By that time, picric acid was not really being used any more as an explosive, more as a feedstock for making better ones. Its sensitivity was problematic and it wasn't very stable ... and the devastating Halifax explosion had turned people off of picric acid. It was TNT that turned the Canary Girls yellow. 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.

[@schautamatic]

Having handled artillery shells and their picric acid booster charges, what I saw was that TNT is an off-WHITE color. Five years later, I made my own picric acid (2,4,6-trinitroPHENOL), which was QUITE YELLOW, thank you very much! Oh, and while nitroglycerine can be set off with a five-pound weight dropped from four inches, I also made some mercury fulminate, which can be set off with the same amount of weight dropped from only TWO inches. Always thought-proving when making primary explosives! 😄😄

[@christophercripps7639]

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, ...

[@Andrew-my1cp]

@@schautamatic I am really confused because it seems that pure picric acid is also pale yellow. I made some and at first my picric acid was exactly that. Pale yellow. But after a recrystallization it turned very yellow. I'm not sure why. Possibly sodium ion contamination that formed some sodium picrate? The recrystallization was somewhat of a failure though. No proper crystals were formed and the contents of the flask bumped and spilled out a lot of the contents which was quite a shame.

How are compounds like this named? Where do some of these names like nitroglycerine/ dynamite come from. And those photographs of the explosion are really cool

[@MrBaileyguitar]

It's also handy to mention that nitroglycerin is a very potent blood-thinner in a solid form. I'm not sure if it's technically the same compound, but my late step-dad took about 1 5mg pill every week or so. Also, am I correct in assuming the nitroglycerin does not react with heat/flame, or did I hear/interpret that wrong?

[@beefcakeandgravy]

detonator cap? So all the movies are wrong then when they blow up dynamite with a firework style fuse?

[@yevrahhipstar3902]

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

[@zameliz]

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.

[@kossankarlsson1080]

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.

[@ke6gwf]

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.

[@BillFromTheHill100]

A fuse goes to a cap. Not electric

umm why are you eating chocolate for lunch😒

[@JOHN0577ANDFRIENDS]

same amount of salt you eat for lunch

[@mudkip_btw]

Joshua Inniss Not like he only eats chocolate

[@wazscience]

@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.

[@Mattrules1111]

You said that nitro compounds dilate blood vessels. If that is so, drawing upon one of your other videos about gun cotton(nitrocellulose) being water soluble, would blood vessels dilate if you dissolved some in water and drank it as well?

Sorry to be picky .. TNT isn't yellow that is Picrate Acid, and the ladies mentioned at 6-56 were working with picrates not TNT . Picrate was also used as a textile dye.

[@nikolai502]

3:00 the copper is probably from the shaped charge, liquid copper which shoots through the plate. Not from the detonator
