you can also acquire your dry ice as at most local grocery stores such as Albertsons, Safeway, and even some Wal-Marts

I use to make bombs with Muratic acid and Baking soda... get some PVC just big ehoungh for a babyfood jar to slide down it, some high concentration HCl or Sulfuric acid drain cleaner, box of baking soda, babyfood jar, some end caps for the pipe, some pvc cement, and a nice sharp rock that will just fit in the pipe.

Cut about a 10" section of pipe and glue on 1 cap. Mark that cap with a marker or something. Jam the rock down in the bottom. Fill babyfood jar with acid and put on the cap. Slide this in the pipe gently against the rock. Dump in enough baking soda to allow for the jar to slide a couple inches, you don't want it packed. Glue on the other cap.

Now, when your ready to blow something up, just grab the unmarked end of the pipe and smack the marked end on the ground a few times real hard to break that babyfood jar against the rock. Throw it and get the hell away. DO NOT GO CHECK ON IT as it may take a few minutes to go BOOM, or it may only take a FEW SECONDS.... so be careful... this would easily take your arm off, if not kill ya.

i've seen a few mailbox's go up due to dry ice bombs. but yes, you can get in a lot of trouble. and as far as the pvc bomb goes. i don't know if i would feel comfortable smacking the tube on the ground a couple times to break the baby food jar. But all-n-all it sounds like fun.

That's actually an improvised bomb normally done with steel pipe and end caps, but that's a bit too big of a boom for my tastes. A guy who was in the EOD (explosive Ordinance Disposal) unit taught me how to make those when I was in the Gulf... He said with steel pipe, it'll shread a car... blow the doors off kinda shread.

Have you ever lit a cottonball and watched it burn into nothing?  Pretty fast yeah.  But there is a solution you can soak cotton balls into that makes the burn rate of cotton balls like 100 times faster.  Maybe someone could remind me of the solution because its been so long I have forgotten :frown:

I remember doing it all kinds in highschool though because its so fun to make little trails of cotton balls and light it up.  It looks like a fireball inching its way along the trails.

I've also made a couple tennis ball bombs, but they don't explode, the just burst open and you have like 250 flamming match heads flying wherever you throw it. is it supposed to explode, or is it just supposed throw fire?

Yeah, the problem is that United Nuclear doesn't like to allow one person to buy both of those things from them. They tend to deny orders they think are for making m-80's.

Thats a reasonably nifty incendiary device.  From my little bit of knowledge (insert grin here), I'll tell ya how I'd have modified it.


First, I like to make things that go BANG when I say so, I don't like shooting bottle rockets at them.  Initiators, especially for flammable gasses and other low order explosives, are pretty easy to rig up.  Go to your local hobby store and get some squibs for setting off model rocket engines.  These fire off of a regular battery (or maybe a 9V?) and just produce a little spark, which is all that you need for your "application". 

Second, you'd be better off using a primary charge to vaporize an amount of flammable solvent, rather than dealing with a volume of expanded gasses.  Gasoline is what most people use for this (by "Most people", I mean people that are into things that go bang in the night), but I think that a mix of gasoline and 91% rubbing alcohol is the best for straight fireball performance.  You could try rupture a tank of acetelyne, but thats a costly tank you'd be destroying and you'd have to use a higher order explosive.

My main fun-fireball-bomb is just a PVC pipe with a squib in it and black powder.  Seal all of the ends VERY good with plumbers dope, then coat all openings with a strong epoxy, a few good thick layers thereof.  Put this into a gallon milk jug filled with your gasoline/rubbing alcohol mixture, run about 40` of line out to it and run a charge to the squib.  KA blooey :smile:

Have fun, be safe.

nitrocelulose, flash paper and gun cotton are basicly the same, I made something
similar but with a glycerine base, managed to get me in lots of trouble with the
police and school system.

As I said, "There are hundreds of ways to detonate it.". I USUALLY use 18ga stranded lamp cord or speaker wire. Just
short the end that's inside the bag with a SINGLE strand, making a "filament" and connect the other end to a car
battery. There's a one-second delay before the BOOM!!!, which I'll guarantee you is WAAAAAAAAAAAAAY louder and
more potent than your gasoline/alcohol mix.

This is a conflicting statement. 40' of line would put you way too close to my trash bag bomb to be even in the
vacinity of being "safe". (provng that the bag of expanded gasses is far more potent than the mixtures you've done).

The trash bag bomb is very simple to prepare and way cheap to make. All you need is a bag and access to a cutting torch.

TRY IT, YOU'LL BE QUITE IMPRESSED.

I don't play with incendiaries, usually. Having friends that have blasters permits allow me to do more than tennis ball bombs :P

ANNM is the shit, google "annm.pdf" Thats something you need more than 40` for.

Please be very careful. As many of you know, I used to work in an explosives research lab testing experimental explosives for the US military. I have seen the results of accidental detonations, and it isn't pretty.

Quote:

Working with any type of explosives is really, really dangerous, but with the proper precautions taken, it can be done quite successfully and harmlessly.




I disagree with the "quite ... harmlessly" part. Again, I have seen too many accidents. For example, using your own post:

Quote:

Fill a 30 gallon polyethylene trash bag with 30% Acetylene & 70% Oxygen.




I noticed you are using polyethylene trash bags. Polyethylene has a tremendous ability to create static electricity. How, exactly, are you preventing a spontaneous detonation due to static discharge? The simple action of the gas expanding the plastic bag is enough to generate the static charge needed to initiate a detonation. Acetylene requires only 0.019 millijoules of energy to initiate detonation.

You didn't mention how you are getting your gasses, but I assume you are getting them from bottles rather than producing them yourself. If so, the gasses are dry and can create triboelectric static discharges. Tribo-electricity is created by the motion of atoms in dry, non-conductive gasses. Again, you can get a detonation while filling a container, initiated by static discharge generated by the gasses themselves.

You also failed to mention that acetylene and oxygen mixtures are slightly photosensitive. Detonation can result from exposure to sunlight. Acetylene will form explosive acetylide compounds when exposed to silver, copper, mercury, or other active metals or their salts. It also reacts violently with fluorine and other halogens. Acetylene gas is thermodynamically unstable and sensitive to both shock and pressure. Both container size and shape have been shown to alter its sensitivity.

Finally, how are you preventing acetylene and oxygen from escaping into the room while you are filling the bag? You have good ventilation? All of your fan motors are brushless, yes? Brushed fan motors generate sparks which can detonate gas that has accumulated in the room. Things such as light switches and thermostats also generate sparks when switching, leading to the same risk. Stove or hot water heater pilot lights are yet another concern. Static buildup generated as you walk across the carpet to move your explosive bag is enough to accidentally detonate your mix.

Personally, I value my fingers, hands, arms, eyes, ears, and life too much to be playing with this kind of stuff. You can pretend that you are being safe all that you like, but the dangers are real and difficult to mitigate.
