Picric acid vs ETN
With all my superlatives of TNP, some people were left with the impression that it's a "must make explosive" and is high R.E. explosive. Well here's
the prove. Think of your bet and then watch the test:

and please if you can, click my link at the end of the video.
Share what you though would be the result. Share witch one you prefer anyways.

Everything is said in the comments to video  Btw, where do you get the parent
alcohol for ETN? Also, what is the ''power'' relation between that two and EGDN?

How many grams ETN was that?

Wow, I've never received so many likes for such a short time. Thank you guys.

Check my last EGDN test, except from reliability, EGDN isn't that much more powerful then maximum density ETN.
Quantity is about 2grams, witch is more like two normal No8 caps. And a whole lot of azide, but that because of the crude hot wire setup.

Did you want to say that EGDN is more reliably initiated than ETN or about the longer shelf life? The channel and conducted tests are great, how do
you mitigate low orders for example for EGDN - is the RDX booster / tight container a must, or are there any compositions based particularly on
EGDN(dynamites?) that will normally go full speed?

EGDN is much more reliable then cast ETN. I recommend a booster for all maximum density materials, but I've set off EGDN with 0.2g azide strapped on
the side of the charge. The same setup with cast ETN was very weak: http://www.youtube.com/watch?v=kdDbO3L3Y0A The large dent was EGDN.

Hmm, I thought that crystalline HE must be more easily initiated than liquid ones (also more sensitive), you disproved that. Then I don't see any
advantage of ETN, except non-volatility, but it is compensated with the short shelf life (all secondary hydroxyl nitrates are rubbish for the same
reason, I'm surprised that NG compositions are/were so widespread for industrial use). Also the source for E is not clear to me, I mean not the actual
one you used, rather where usually it can be found.

I proved that, look at my ETN critical diameter video. As for ETN being rubbish, at the end of the video, there's short review on that topic. One
thing is sure, ETN is no doubt No1 choice for the high power plastic explosive on a budget. I also have a video on that-"ETN plastique with no inerts"
If you can't find some eritrithol product, you can try manitol or I'm not sure about this-sorbitol. NC stores kinda good and detonates almost like
TNP.

i believe you mean the sugar for the nitration, its sold as a health sugar commonly under the name ''Sukrin'' tastes pretty good too
also the brisance of ETN is estimated to be approx. 1.6 - 1.8 (being ''power'' 160-180% of TNT)
these estimations were done on the background of results i was told by a person who used some secondaries we could find the brisance on, and as it was
in between it could be estimated that way, but not with accuracy at all, i believe it was a little bit less strong than EGDN (1.8??) which IIRC was
used as the top brisant to compare it to

I wouldn't give 1.8 to EGDN, due to it's density and velocity.
EGDN-7300j/g, 1.48g/cm2
ETN~6500j/g, 1.6g/cm2

''EGDN is more powerful than nitro. Lead block 650cm3, brisance 185% TNT''
http://www.sciencemadness.org/talk/viewthread.php?tid=5057
its 1.85 but i guess this would be MAX brisance, anyways its pretty much maximum density all the time as its a liquid
