A Song of Lab Coats and HMX

Or: How I Lost My Lucky Lab Coat


When I was but a callow youth, I was supremely interested in explosives and explosions, like all young children should be.

The difference was that I had access to the chemicals and equipment needed to actually go ahead and make these explosions (and explosives) myself.


I started off with small things, grinding up sparklers and compressing the resultant powder into charges, which acted more like flares or rockets than actual explosives.

Incendiaries were fun too, like poor man’s napalm (Styrofoam dissolved in two-stroke fuel), then proper napalm (No, I’m not telling you how to make this stuff) and some rather exotic white phosphorous/napalm derivatives that I never actually had the courage to test out.

Thermite was great fun too, just watch (or don’t watch, preferably) the UV emissions. …You know, I never got around to making those thermite grenades… A project for another time, I guess!


Next up was good old black powder. It’s easy enough to find recipes on the web for this, and fun to play with too. Uncontained it burns quickly rather than exploding, and makes a good show when grains of it are mixed with various metals and metal salts for colour. Fireworks! Sadly (or luckily) I used up most of my stock making pretty colours.

Unsatisfied with the lack of BOOM in my life, I decided that the next best thing to do was making ANFO (ammonium nitrate fuel oil mix). This is a general-purpose and mining explosive, since it’s easily handled and very stable, with the caveat that the ammonium nitrate absorbs water like no-one’s business and soon becomes less than efficient as an explosive.

Unable to get my hands on pure ammonium nitrate (this was a very good thing), I settled on the highest nitrate concentration fertiliser in my family’s garden shed, ground it up and mixed it with enough kerosene to hold it together in a solid mass, and took a magnesium taper to it. To my dissatisfaction, it just burnt. Very violently, but it only just burnt!

Five seconds of staring at flames merrily burning away in a fire pit later, I realised that in my enthusiasm I had forgotten that the best high-explosives are actually quite stable and need a blasting cap or similar sharp shock to detonate. Whoops.

I then had the bright idea to think that nitroglycerin would make a great detonator, given how unstable it was! Half a second later I slapped myself for getting such a terrible idea and made myself some mercuric fulminate.


Shit started getting real right about now. I looked up detonation velocities, compound and plasticiser densities and brisance values, and decided that RDX (the main ingredient of C4) was the best non-experimental explosive that was in my capacity to make. We may have differing definitions or values of ‘best’.

I didn’t have much equipment to my name, but it was enough to start myself off with TNT production, which is the pretty little molecule below. I made about 25g of the stuff as a test, and it detonated with a satisfying CHOOM noise when I set it off with the fulminate.




I didn’t have any of the apparatus I actually needed to confirm that I had made TNT, or its purity, or my eventual yield – the fact that it exploded was enough for me, which in hindsight was terrible scientific method.

Satisfied with my ability to not stuff up a basic nitration reaction, I proceeded straight to RDX manufacture. It is terrifyingly easy. 25g in a single reaction is simple, quick, and relatively cheap to boot.

The resultant stick of plastic explosive (after processing) cut a satisfyingly large gouge out of a big tree stump when detonated as a cutting charge.


Flushed with success, in my youthful idiocy I decided to do a simple linear scaling up of the reaction, all the way up to 500g. This is how I lost my lucky lab coat.


The reaction went runaway on me, the stoichiometry shifted to favour the production of HMX (which gram for gram is one of the most powerful conventional explosives in the world), and there was still enough reagent concentration that even when dumped into the too small ice bath the mix spontaneously exploded, sending acid and glass shards and ice water everywhere. It was mainly acid and glass shards.

Everywhere also included my left shoulder, which was not as protected as my torso or face, and I ended up with three large shards of my ice bath container embedded in it. They also had a decent amount of acid still on them, which probably had the side effect of turning a small portion of my body into high explosive. In hindsight, THIS WAS TOTALLY FUCKIN’ METAL.


The moral of the story is – If an explosive is in any sort of container, it becomes a fragmentation weapon. If you can see a fragmentation weapon, it can kill you.

The second moral is – Make sure you know what secondary compounds your reaction makes, because they are potentially more explosive than your desired product, and you should treat them nicely.


Also: I’m super hoping that ASIO/NSA/Other national intelligence agencies’ datamining networks haven’t flagged this post as ULTRA TERRORIST DEFCON NEGATIVE FIFTEEN GORILLION. If you spooks are reading though, I have some interesting ETC-APFSDS infantry weapon concepts to bounce off your weapons R&D guys.


Stay angry my friends.

Our favourite DBZ characters

Girls night apparently – Windfyre and Ebolabooze are busy…ish.

Beer and watching Dragon Ball Z Kai. Yay, girls’ night…

This led to discussion on which character was best with everyone except Lorekai being convinced they had the inside scoop.

marsy: The obvious answer is Piccolo. Dat cape. Dat mysterious wind. Dat unresolved parental issue. Dat consistency. Dat inspirational revival scene.

Watch from 5:28, or watch all of it with your eyes shut. Try not to giggle.

anit the Flea: Gohan is my vote. For the mullet. But oh God all that unfulfilled potential 😦

wildfillysama: Supreme Kai is best character. Hardly any screen time, hardly any use in any way at all, but still best character. Purple. Mohawk. Passive aggressive. Email to ask for the full essay.

Hey, hey, you!  Yeah you!  The ugly one with the mullet and the half-grown moustache!


Read this:


This has been a great read, simply a fantastic, compelling and realistic story of superhuman power in the modern world.

In fact, I love it so much that I’m not even going to speak to people unless they’ve read the whole thing.

Incidently, it’s a bit over 1.5 million words.  The LotR trilogy was 473k.  Take your time.

wildfillysama: Nanowrimo, the finishing line.

Last night I broke 40,000 words in a fit of hastily produced, awfully thought-out prose. I skipped out on writing for a few days and had to make up for it in very rapid style. But still, the finish line in now in sight!

Currently I am in Canberra to attend a conference. Hoping to find time to write in between listening to papers and furiously writing my own. Living dangerously.

The flights over to Canberra were rather exciting. While flying from Western Australia to Sydney, there was some rather unpleasant weather. Lightning was going on outside the plane window, and the plane itself was having happy fun times with gravity. I was dozing off as the plane came into landing but was rudely awoken by the plane suddenly dipping a lot, and the entire cabin screaming and waving its arms. First time that’s ever happened. Landed just fine, but felt a tad motion sick. Ate two Krispy Kremes and a strawberry milkshake as a consolation. Felt much better, but then had to get on an even smaller, noisier plane to get to Canberra.

Haven’t met any politicians yet. Hit count is therefore at 0. Will update if get arrested.

Now, off to write poetry analysis! And another 10k words for Nanowrimo…
