I've seen one DIY tip for making a bomb (not dynamite). It said you

Erm..


Which, for obvious reasons, is apparently increasingly difficult to get
hold off.

No, it's not.


You have to empty some of the nitrogen in to the newspaper and then roll
the newspaper up. Dip the rag in diesel and then put it in the end of the
newspaper. You then have to light the rag and it then recommended
"running like f**k" and not doing it in a "confined area" such as an
"alley". Unless, of course, you wanted to blow it up.

That, fortunately, has no chance of exploding.


Surprising how easy it is. This is of course simply observational quoting
and for scientific use and reference only.

Quote some more like that, it may help!

And for your information...

In Australia all products, including fertilisers containing greater than 45%
ammonium nitrate have been designated as security sensitive ammonium nitrate
(SSAN) and will be subject to regulation. SSAN includes calcium ammonium
nitrate which is not classified as a dangerous good, and dangerous goods
with UN numbers 1942, 2067, 2068, 2069, 2070, 2071, 2072, 3375 and 3139,
where applicable.

Additionally...
New polymer coating makes it harder for terrorists to use Ammonium nitrate
as a bomb-making material.

Ammonium nitrate is a widely used fertiliser which has been used in several
IRA attacks, the World Trade Center bombing in New York in 1993, the
Oklahoma City bombing in 1995 and the Bali bombing in 2002, amongst others.
Millions of tonnes of ammonium nitrate are produced each year for use as a
fertiliser. It can be turned into an explosive by mixing the chemical with
fuel oil and, while it is not necessarily easy for would-be bombers to do
this with fertiliser-grade ammonium nitrate, it is not impossible.


Many year s ago I remember seeing a video about quarrying.
IIRC a substantial hole is bored from the top of the cliff downwards.

The hole is filled with bags of Ammonium Nitrate and Diesel is poured in
after. A stick of commercial mining/quarrying explosive is shoved down the
into the top of the mixture together with its detonator.

It may be that the fertiliser/deisel mixture can be detonated with just a
detonator but I suspect that using a stick of makes the process more
reliable. However I'd hazard a guess that just setting fire to it won't
make it explode.

Now I'm reliably told that mining quarrying explosives are so stable that
they can be burnt on a fire without exploding.

That's the difference between "low" and high explosives IIRC

Gunpowder explodes by burning (very fast)

High explosives are set off by a shock wave and explode at the speed of
sound (I presume in that medium)

TNT would just burn away if you put it on an open fire, it needs a
percussive initiation to make it explode

(that could have been phrased better)
