Really? I didnt know about the caffeine. Well, thanks for sharing !
Actually my only exposure to NG was through WW2 relics found on the beach. We found quite a lot of Sticky Bombs handles, all the glass spheres were broken and we managed to get some NG on our skin by digging through the mud.
There was very little NG, the effects were very light and I actually compared the vaso dilatator effect to having a very strong coffee and inhaling an asthma spray. I didnt feel "bad".

Of course, it happened again a few days later when I put my hands in the bucket where I was soaking the handles... tiny droplets had floated to the surface and were still visible on some parts of the handles.
If there are any Brits reading this, sticky bombs are *not* what you see in Saving Private Ryan. It's a part of your history ;)

@LL, That is a nice test and really puts the damage that explosive can do to tissue and bone into perspective.
Pig is a good choice too because it's skin is so similar to human skin.

Was the pigs foot thawed out prior to the test?
Did you find a large amount of small metal fragments from the detonator casing inside the wound?

Pig leg


Well. Temperature leg was 20C through before test. Inside I not see metal parts. But very many crushed fragments of bones. Before photos, fragments was be washed out from hole.
Doc.

Urbanski

I am assuming "Urbanski" is the author. Which of his books are you referring to and could you post a link to it on amazon? (google is blocked in my current local and "Urbanski" isn't turning up anything useful on Chinese bing.com)

Thank you in advance,

What is the book's title? I've looked already and couldn't find "Urbanski" with my eyes or a hot key search.

I think Xeon meant Davis's COPAE which is in the FL . . .

You could try this link?

Chemistry and technology of explosives tome 1 through 4.
More than 2400 pages Worth of reading. Exceptionally detailed in most "common" explosives, propellants, the technique of making them and how they are used / why they are used instead of this or that other EM.
I love détails. Juste the section on Nitrocellulose has about 40 or 60 pages discussing cellulose itself before going into nitration, stabilisation etc.

And yes, COPAE from Davis is also a "must read" though it is my opinion that you wont learn as much.

Maybe that's because I dont have a background as a chemist, juste more than 30 years in the hobby and need to be "taken by the hand" a litle bit more further. As someone said, I'm closer to the middle age Alchemist than the modern Chemist with his calculator, computer and mass spectrometer ;)

Another excellent book, also more modern therefore I would say for more Advanced chemists is High Energy Materials from Agrawal.
It's also very interesting to compare how information is presented or disclosed (for lack of a better word) when you compare Urbanski (former eastern block), Davis (US) and Agrawal (India).

I believe all these books and many more are in the SM Library.
