B is for... BANG!.

This is a dont-try-this-at-home section. Just a few ideas gathered together
all about making home-made explosives and other things that are pyro-related

This is the first explosive that most of us make. I made my first batch at about
seven years old. it was a good experiment.

you will need potassium nitrate (kN03), Charcoal, and sulphur. I use a small
mortar and pestle to hand-grind the individual parts into a very fine powder
and then combine them together to form the completed black-powder.
The ratios are about three-quarters ground kN03, with the remaining quarter
charcoal and sulphur. A little more charcoal than sulphur works better.
and a little more charcoal to sulphur increases the burn-rate.
75% kN03 (potassium Nitrate), 15% Charcoal, 10% Sulphur.

the mix can be ignited carefully on a piece of paper outdoors. and this is a
good way to test your mix. When you have a mixture you are happy with you can
make it go BANG by packing it gently into a small card tube and fitting a fuse to
the top and sealing it up with tape. The more confined it is, the louder the bang.

In the past I've used home-made black powder in home made brass cases in a .410 shotgun.
the sense of satisfaction is wonderful. I don't shoot small furry animals, and prefer targets.
Accurately hitting the mark with home made ammunition is seriously cool!


An exothermic reaction. with aluminium-powder, and Iron.
This is a fun experiment. Best to do it outside though or you will
rather quickly burn a nice hole through the floor, Even if it's concrete!

You will need aluminium powder. You can either buy this or just get out your
angle-grinder and finely grind-up some aluminium.

Rusted iron, either make this by getting some bags of wire wool and allowing it
to rust or buy yourself an old ford car, give it a kick, and collect what falls off.

a short length of Magnesium tape to use as a fuse.

A suitable container. Somthing like an old paint-tin.

Simply pack the tin with the mixture of fine aluminium and ground-up rust. 1 part aly to
around 2 1/4 rust. Make a hole of about 1/2 inch diameter in the lid and stick the magnesium
tape down into the mix. Pop on the lid with the other end of the magnesium tape out of the
top about 2 inches. Put a piece of tape over to seal it up so all of the chemistry doesn't
fall out but you can still get to the magnesium tape fuse. In this state, it can be stored
until you are ready to use it.

Place it on the bonnet of your neighbour's new jaguar and light the magnesium tape with a
blow-torch. Settle down with a glass of wine and wait until it burns it's way through the
engine-block to the road underneath. (and then to the core of the earth).


Smoke bombs are easy to make in the kitchen. In the simplest form they are a solution of
potassium nitrate and sugar, potassium nitrate can be found in on-line stores. and sugar,
of course from a local supermarket. Smoke bombs can be used to give cover / screen if you are
using another of the items here in the listings to rob a bank or melt holes in pavements.

Put about 3 parts potassium nitrate and 2 parts sugar into a saucepan. Don't panic, the quantity
of each is not that critical. Just use a good-bit more potassium nitrate than sugar.
If you use too much sugar, you will find it hrder to light, but will last longer. So a little
experimentation is needed to produce something to suit your needs.

Heat the saucepan. Stir the mixture regularly / mix well with a stickor large spoon.
don't cook it too hot, and be patient. This is like making toffee. The mixture will
melt and mix into a brown colour smalling like toffee. Continue heating and mixing until
the ingredients are totally liquid, then remove from heat.

you can test it by pouring some out and lighting it. When you're happy with your mix, Pour
the rest of the liquid onto a thin paper/card tube like a kitchen-roll-tube with one end taped-up
leave an inch or two at the top of the tube. It will burn slower once confined in a tube so always
re-test until you're happy with it. make a small hole in the top of the now-cool smoke-bomb and add
a fuse. Sometimes a little black-powder of KN03 gives it a head-start. Fold in and tape-up with the
fuse poking-out the top. It can now be stored ready for you to take-over the nearest small country.


Great or opening up the sides of nuclear fallout shelters.
You will need the following.....

Oxygen. get a home welding oxygen bottle and regulator from your local DIY
store or order it on-line.

length of thin wall steel or iron pipe. about 3/4 inch internal diameter.
A reel of aluminium wire. 1mm to 2mm is good. Iron wire of the same diameter too is also needed.

With a 3 foot piece of tube. Cut your wire into lengths. you will need to have
a little experimentation with the iron to ally mix. But a good place to start
is 3 aluminium wires to about 5 of iron. Pack these into the length of thin-wall
tube. make sure they are nice and tight in there. you need just enough space between
the aluminium and iron wires to allow oxygen through.

To end of your thermic-lance you attach the oxy bottle and regulator. If you don't have
a proper end-cap / hose adaptor improvise with cork/epoxy-resin/gaffer-tape.

low/mid oxy presures are OK. And you will probably need a blow-torch or a magnesium taper
to get it going. Once it's lit. Be careful not to get caught while you are burning your
way into your local bank-vault.

A great way to start a barbeque. But another for the garden rather than the kitchen.
you will need the following....

polystyrene packaging I prefer the small irritating chippings.
high-octane petrol I use 98 or 99 octane in my motorbike. so have plenty of this around.
glass or plastic bottles.Plastic if planting and lighting. Glass if thrown.
visco fuse or cord soaked in petrol. Visco fuse can be bought openly in the UK
from pyrotechnic suppliers. but fuel-soaked cord or rag is easier.

Get a bucket. half fill it with the small polystyrene packing pieces. Then add about a
pint of petrol to start. mix it up with a wooden stick. Add more fuel to the mix and
keep stiring. You are looking to make a thick oily goo.

when you have a bucket of goo. Pour it into the bottles. If you are using glass, allow
enough room for a petrol-soaked-rag at the top. or visco-fuse pushed into the goo sealed
with paper and tape. In a plastic bottle use the screw on cap with a hole in the top.

In use. with a glass bottle. Light the fuse and throw it at the target. The bottle
will break and the oily goo will hold the flames on the target. This is far more
effective than just a bottle of petrol as the fire caused by petrol alone soon dies
away and is less intense and easier to extinguish

Nitrogen Tri-Iodide.

Nitrogen Tri iodide is FUN. It's one I have made in the garden many times
and is a good demonstration of the sensitivity of a compound.
It's also powerful enough to initiate other explosives, so watch out!
In the past I've set it off by tapping it gently with a stick etc.. so be very
careful if this one when it's dry, and only make very small batches of it.
You will need some ammonia, sone iodine and I use tripod-stands and filter-paper

Add 3g by weight of iodine to 15ml ammonia in a non-glass beaker. Mix well and then
let stand for a minute or so. Clip a disc of filter-paper to the top of the tripod
stand and pour the liquid evenly over the filter paper disc, and use another clean beaker
to catch the liquid that drips/runs through. this can be poured through again if any more
crystals have formed in it, BUT Dispose of this liquid.

Leave it in a draught-free, well sign-posted area to dry for between 40-mins or an hour
To detonate it, gently touch the top of the filter paper with something long! you may need
to wear ear-defenders, this can be quite loud!

A friend of mine made some of this at school and poured small patches of it on the floor
and left it to dry. It was triggered by people walking on it. This is NOT advised!

Chlorine Gas.

You will need the following.....

Bleach etc. containing Sodium hypochlorite NaClO.
Drain-cleaneretc. Type containing Hydrochloric acid HCl. (some are sulphuric acid H2SO4).

Mix them together and get the hell out of there. This stuff is nasty. it burns causes
suffocation and choking. Please don't do this unless the third world war has started....
