Does anyone else on the net like to blow things up or see huge fireballs?
I haven't been too active lately, just a little Nitrogen Tri-iodide and
misc. small bangs/flashes. I have been thinking of buying a small piece
of land to blow things up on 'though. I am especially curious about the
effect of placing a container of liquid ignitable gas in a pile of thermite
and igniting it. I would probably start small with a disposable lighter and
then move on to something like a can of starting ether... Boy! I bet it
would look real keen. How about it fellow netters? Any suggestions (other
then the obvious safety precautions)?

Quite the hobby. Sounds more entertaining than debating about gun
control and after all, this group is net.rec. We can discuss what
we each do for recreation here and present our thoughtful, incisive
ideas on gun control (or the lack of) on net.politics. A discussion
about debate as recreation may be enjoyable though. Format and style
are very important parts of debate (and two things missing from most
of the extended gun discussion.)
Sorry for the digression. Back to the original subject:
Blowing Things Up
How about a litre or two of gasoline? Use a large paper box to
concentrate the vapours above the liquid. Then let it rip. Nice
fireball.

A shotgun shell filled with gunpowder, with nichrome
wire going through the length of the shell (no primer)
can be turned into a "nifty" explosive. Simply
wrap it in masking tape to a depth of ~2". Place
this where you want it, connect an unplugged extension cord
to it. Lay out the cord to a good distance (around
barriers etc.) and plug it in. When I was young an
older brother did this. He excavated a 2 foot crater
in the back yard. It was quite impressive. If you
people are after bigger fun than that (like the 10x10x10
shed suggestion) then please stay away from me.
Notice: getting hurt by this kind of thing is a real
possibility. Don't say I suggested it.
These may not even be my opinions: my employer is certainly not involved.

Many years ago, I had an acquaintance generally known around the county as Crazy Barry who demonstrated a great fondness not only for spectacular explosions, but also for large caliber handguns, fast cars, machetes' and the indiscriminate use of martial arts. Later, the folks around the Co-op said it was only natural when became a police officer. The following idea was his: One of the neatest enormous-bright-orange-fireball-type explosions you've ever seen, let alone created, can be made very easily and at great personal danger by simply taking one of those $1.79 propane torch cylinders, taping on a 15 minute road flare, backing off about a half mile and shooting it with a 30-.06. This is best done while standing behind some impenetrable barrier such as a concrete bunker, granite wall or a '50 Buick. If you just want a taste of this effect, you might use a discarded "empty" cylinder for starters. This conflagration is guaranteed to add a festive touch to any outdoor occasion. The inherent dangers should be intuitively obvious to even the most casual reader (so like, don't tell them you heard it from me, eh?).

I really think that the best bangs are made by large quantities of very hot rock with incorporated Hydrogen Sulfide, Sulpher Dioxide, and water vapor. Such bangs must be created by rapidly decreasing the pressure on said rock from 100 atmospheres to one atmosphere. We at Vuncan's forge specialize in such bangs, drop us a line sometime. P.S. We're busy in Hawii right now, so give us a few weeks.

Sure, as long as it's not classified as abnormal behavior!
My fellow residence house pyros back in college came up with a very
creative way to get large momentary fireballs, approaching 40 feet high
and 10-20 feet across. We had a large "pot" in the center of a
courtyard, in which we would regularly have small fires. Scattering a
gallon of sawdust into the air over the fire made a nice "poof". Three
stages of sawdust, tossed up in synchrony by 5-10 people, resulted in a
very nice explosion indeed.

I used to make model rockets which would blow up at the zenith of their flight,
using variations of the following formula:
potassium perchlorate
magnesium POWDER
This will create a brilliant white fireball. Changing the proportions of the
ingredients will affect the rate of burn. 50/50 works well.
Adding sulfur creates a more powerful explosion, with a less dramatic fireball,
but I am told the combination is UNSTABLE.
Various other chemicals can be added to make the fireball different colors,
I don't remember for sure, but I think that these are right:
strontium nitrate- red
cupric oxide(?)- green
If enough people mail to me expressing interest, I will write or mail out an
article about exploding model rockets, boom and flash varieties, and how to
contruct and launch same while retaining life and all body parts :-).

{dual,ihnp4,etc}!fortune!ranhome!randywb@hou4a.UUCP (W.Baumgartner) (02/26/85)
In a previous article potassium perchlorate was mentioned as an ingrediant of a rocket formula. THIS SHOULD NOT BE USED IN ANY PYROTECHNIC DEVICE. Chlorate and Perchlorate compounds are powerful oxidizers and may ignite and/or detonate spontaniously when mixed and/or packed with other compounds. A much better (safer) choice is potassium nitrate which is the choice of the experts (fireworks manufacturers). Better safe than sorry, Werner B. P.S. I can recomend some exellant reading on this topic if anyone is interested.

Lieman Beware! Many people have seriously injured themselves playing with this substance. I suggest starting out small ( < 1 oz. iodine ). Here is the nice simple method: Take iodine (not iodine solution) and mix it with ammonia. Let it sit for a while and then run the mess through a paper towel. The lump of stuff will blow up as it dries out.

NI3 has a highly unstable crystaline structure so it undergoes decomposition when dry. Hydronium ions in water also tend to cause the stuff to decompose. Though not recommended (you should use it when you make it!) it is possible to keep NI3 "wet" in certain solvents without it blowing up. What is important is to not have it dry on any part of a container. -eli -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Eli Liang --- University of Maryland Computer Vision Lab, (301) 454-4526 ARPA: liang@cvl, liang@lemuria, eli@mit-mc, eli@mit-prep CSNET: liang@cvl UUCP: {seismo,allegra,brl-bmd}!umcp-cs!cvl!liang

Actually, 99% denatured alcohol works quite well and is very practical. Also convenient and more-or-less readily available. Xerox uses many pint-bottles of the material (shipped in cases of 12) and it seems to wash about right. Whatever you do, WEAR GLOVES and dispose of them asap. Half a bottle-cap full is usually more than enough to make small craters in cement. Unnamed locals once determined the proper amount to be put under the leg of a chair, such that the occupant would recieve quite a surprise. However, this required weight on the chair...detonation of unoccupied chairs revealed enough power to catapult the chair across the room. Gosh, each classroom could be a minefield. I'd better watch out. -dave

> Does anyone know an "easy" way to make Nitrogen Tri-iodide?
That one is easy! Get yourself some iodine crystals and some household
ammonia (The kind without the soap in it!) You put a PINCH of the crystals
into a beaker full of ammonia and let the conversion take place. WARNING
the reaction is exothermic and the whole beaker can get hot and start popping
if you put too much iodine in. Trial and error works to get the ammount
right! :-)
Once the reaction has completed, you might change the ammonia every few hours,
you let the black crystals settle and rinse off the ammona. The trick in
handling the stuff is to not let it dry out so you have to pack it in water.
The stuff is really HELL in keyholes.

"Beware" is right, and make that MUCH less than 1 oz. of iodine (about the amount you can hold on a paper match is a good starter. This stuff is also HIGHLY unpredictable. I made some and partially dried it on a 3 X 5 inch index card once. I scattered most of it around on the floor, but there was still quite a stain on the card. I let the card dry THOROUGHLY, and then threw things at it, whacked it with a ruler, and even put it on the floor and stomped on it. NOTHING!!! (Meanwhile, the crystals on the floor were happily crackling and banging whenever anyone walked by, or sometimes just by themselves.) I had decided the material left on the card was quite inert and was carrying it to the wastebasket when it lightly brushed across the back of a friend's shirt. There was a **LOUD** BANG, leaving a big iodine stain on the shirt. My friend said it felt as though someone had whacked him with a belt. Thank God it was his back and not his face! I have NEVER fooled with this stuff since. Nitrogen tri-iodide is HIGHLY explosive. A whole ounce of iodine, completely converted (I was using laboratory-grade ammonia solution) would probably blow your hand off! Bob Nichols @ AT&T Bell Labs, Naperville IL ihnp4!ixn5c!nichols

It's good to see that the younger generation is carrying on
some of the traditions I remember from the 60's. Yes, NI3
*IS* real unstable when it unhydrates, so watch it. I'm
surprised that no one mentioned the best way to increase
your yield, limited by the low solubility of iodine in water.
Iodine is much more soluble in a solution of KI (or NaI, etc),
so add the I2 crystals to a weak KI solution first, then add the NH4OH.
Keep the precipitate moist until you're ready to use it.
We used to have a lot of fun dabbing a little bit into somebody's
door lock. They'd insert the key, and be greeted with a sharp
crack and a purple cloud. Ahhh, days of my youth.

I remember Nitrogen Tri-iodide well. Haven't made it in many years. I agree with the idea of using a KI solution to increase yield but, be careful. I was a chemistry lab assistant a few years back in high school. I mixed up a 500 ml batch of the stuff after school one day, intending to quickly separate it into much smaller quantities while still safely in solution. I was called away for a phone call and forced to leave it, well soaked I thought, in a ventilation cabinet when someone found me to tell me of a phone call. I expected a short delay but was detained a couple of hours. Fortunately I left the lab locked because my creation decided to explode, destroying a number of windowed cabinet doors and a ventilation hood, along with various glassware. Smelled terribly and lots of purple smoke. Needless to say, I was trasnferred to math assistant for the remainder of the year. My more recent explosive hobbies have had to be more make-do (no more chemistry assistantships) but are still quite fun. I try to avoid destroying anything valuable (cabinets, labs, me).

I had forgotten this addition, and couldn't remember what is was. As a kid, I had NaI as a medicine (ack!). I kept trying to make this tri nitro iodide stuff and I could never get it to dissolve well. Any way, someone said to use NaI, so I did. It worked. However, when it was about dry, I poured the semi-moist crystals onto some filter paper. Since it didn't pour too well, I gave a minute tap with my little finger. Needless to say, It went off (Since none of the other methods I tried ever worked, I had fewer precautions then necessary). The little pieces of the plastic bottle missed me, however, my face was completely black. I thought I had gone blind until I took my glasses off. This gave me the appearance of something out of Gilligan's Island. My brother ran out and while I was sitting there in a daze, he started laughing (some brother huh?). Anyway, It took a while to clean my face off, and even then there were little bits of crystals embedded that took a week to get rid of. The moral is: never expirement by yourselves without knowing what will happen (I thought it was supposed to give little pops). Had I made a little more, I suppose my brother would have had to find a convenient story to tell my parent's. Oh well, just had to say something.... Darin Johnson.

Unfortunately, we had second thoughts about that an hour or two later because we started worrying that it might be the actual -OH ions that keep the stuff stable (present in larger quantities in H2O than C6H12!) and had a "horrible" few moments with the "defusing". Does anyone out there know for a fact whether this is true or not? If NI3 is stable in a non -OH bearing solution like cyclohexane, that would be wonderful since it decomposes in most polar liquids. Cyclohexane has many properties which would make it the perfect solvent for NI3. Its nonpolar, low density, low boiling point, etc... speaking of NI3 experiments, we discovered a while back how annoying it was to get even the tiniest amounts on the soles of your shoes... ouch! -eli -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Eli Liang --- University of Maryland Computer Vision Lab, (301) 454-4526 ARPA: liang@cvl, liang@lemuria, eli@mit-mc, eli@mit-prep CSNET: liang@cvl UUCP: {seismo,allegra,brl-bmd}!umcp-cs!cvl!liang

I though I would share a similar story for other people with similar interests. When I was in 10th grade I was at the peak of my diddling with combustables. My latest thing was Potasium Chlorate and Red Phosphorus. It was really great in small quantities. One day (while the rest of my family was on vacation) I decided to mix up a big batch. I made it in an 8" x 1" Pyrex test tube (about 3/4 full). I took some extra effort to grind the KO3 extra fine so it would give more of a bang instead of a PUFF. I was holding the test tube in my left hand, mixing the contents by spinning the test tube when it went off. I was not wearing my glasses (or safety glasses) at time. I was blinded and stunned for a while. Fortunately I did not pass out. I ran out side and yelled for help. The whole block heard the WUMP when it went off. I lost sight in my right eye, my left index finger, and my interest in chemistry. I am still carrying pieces of Pyrex test tube around. Glass being an innert substance is not rejected by the body. I heard later while I was in the hospitol that a piece of glass had gone through a cold water pipe nearby. I am lucky to be alive. For those of you who have not yet been bitten: 1) SMALL batches 2) SAFETY GLASSES, and most importantly 3) QUIT while you still have all the parts you were born with. I toyed with Iodine/Amonia copmbinations before. I always strained it out onto filter paper to dry overnight. The next day I always found a chared piece of filter paper. John Milton

The article by John Milton regarding the loss of his eye and other important parts should be taken to heart by anyone even remotely interested in "Blowing Things Up".

Pyrotechnics is an art and science which can have serious side effects. The best advice I can give anyone is to know what you are going. Go to the library and research the subject along with a good dose of chemistry. The most important thing is not `knowing what to mix'. But, `knowing what NOT to mix' since certain combinations are unstable, and not used even in commercial situations. Trying to get more bang for the buck is dangerous at best.

The "rocket through my parents' picture window" reminded me of something that
my friends and I did when I was a teenager--
When I was in 11th grade chemistry class, a kid came up to me and said,
"You want to know make rocket fuel? Take potassium nitrate and sugar, mix
them, and cook the mixture. The result is rocket fuel." The kid was very
evasive when questioned further. Being interested in chemistry at the time,
a {pyromaniac} friend and I decided to try it out. We used equal amounts of
potassium nitrate and sugar, since we weren't given any proportions. We mixed
the two (granulated) together in a large Pyrex(tm) test tube and set the tube
in a support stand over an alcohol lamp. My friend stirred the mixture with
a glass rod, and we saw the mix start to melt and run together. Approx 2
seconds after my friend removed his hand from the mouth of the test tube there
was this LOUD hisssss and a ball of black ashes hurled itself from the test
tube and disintigrated on the ceiling. The room also filled with VERY dense
gray smoke. A few days later I casually mentioned this incident to another
friend who was into chemistry at the time, and, not thinking that he would try
it, didn't tell him about the smoke and flames. The next day, he told me
about his "experiment". He did the same things we did, and got the same
results with two differences. 1)His set-up made a "perfectly tear drop-shaped
flame about 6-12 inches long. 2)His mother threw him out of the house while
she aired it out. After that, we used the mixture "un-cooked" as a smoke bomb.
My sister-in-law freaked out when I showed her "how fill a room with smoke
in 10 seconds".
Ah, to be young and fearless--
