You're going to have to put the bursting charge in the center of the thing
and it's going to take more than a firecracker.  If you can find 'em,
an M-80 in a baggy inside the balloon will work fine and the Jello
will muffle the blast.  I know from long ago experience dispersing 
garbage bags filled with a substance of bovine extraction :-)

Failing that, you might could build a mechanism that would puncture
a CO2 pellet gun cartridge when triggered by a monofilament line
attached.  Don't know how it would work.  Explosives really do the 
job much better.

Hello fellow pyros,
	I've been fooling around with the ammonium tri-iodide compound lat night and one went off unexpectedly about 1 foot in front of my face.  It was only one single crystal.  I immediately got the ringing in the year and I thought it wasn't that serious.  I was hoping that a night of sleep might get rid of it.  Now I can't hear everything in my left ear.  My left year is not completely deaf, I still can hear very little of it.  Did anyone have a similar type of accident or problem?  I'm hoping that this heari



ng problem isn't permanent and will heal in a few days.  Maybe this is wishful thinking.  If anyone out there also had an explosion occur near their ear and their hearing was not impared, how long did it take for the ringing in the ear to wear off?  

Thanks

You are facing the same problem that has troubled the military for at least

Most of the "expedient" procedures that I have seen are based on CofP&E.
The treatment by Davis thorough, for the times. It is very much out of
date - there may be other processes that are much better.

Look in Chemical Abstracts for more recent information. Also find a few
good books on Energetic Materials, ones that describe proper laboratory

No.  Although enhanced radiation devices (neutron bombs) may achieve antipersonnel
effects at a distance by irradiating the target with reduced shock wave effects
(a consequence of the device being detonated at a distance), engineering projects
generally require a low yield (fractional kiloton to a few kilotons yield) set off
right inside the target site (usually a sealed underground cavity).  Neutron bombs
are really no cleaner for their explosive yield -- and -- in any case fallout from
the earlier dirty bomb engineering projects was supposed to be contained within the
underground explosive cavity.

If the wire is only 10 metres shorter than your building, the blob will

As I recall, there is a "pull-popper" noisemaker type item, where you pull the
string and it go "bang".  Cram one of these in a firecracker, and then just
use the right length of string for the burst height you want.

Or, just wrap string around the balloon.  When it gets to the bottom going
pretty fast, the string will rupture the balloon nicely, I imagine.  Just
tailor the height for optimum dispersion.

I remeber hearing a few years ago that a plant blew up that made the propellant
for the Navy's Pheonix missile.  Apparantly, the propellant is a solid charge
that is shaped on a lathe-type machine in the plant.  The shavings had
accumulated because the vacum evacuation system had failed.  Anyway, these 
shavings accumulated and were set off by some heat source.  KAABOOOOOMMM as
all the propellant went up in the room.

No - N2O is NOT produced when NO2 (N2O4) decomposes. It is produced
when A Nitrate decomposes - at low temperatures. The problem is, there
is usually some production of NO and NO2 as well.

A method you may want to try is by attaching a thin line (fishing line?) to
the detonator, and have your initiating charge go when a sharp tug is
applied to the line. Make sure you allow for the line to stretch a smidge, too.

As for what explodes when you pull it, I dunno. Maybe you can base it on the
same principle of those string boobytrap firecrackers. They have a friction
sensitive charge painted on the string where the string is doubled back on
itself:

Yep. The belief was also a myth. You can walk into many bookstores, and buy

Yes, it is very unpredictable. I have had first hand experience with its
unpredictability. I first heard about the pool chlorine + brake fluid reaction
a few years ago. It sounded like fun so I bought a container of brake fluid and
the chlorine. (calcium hypochlorite, I believe). I mixed the two together
several different ways in various containers and obtained some nice burnouts.
It seemed to take from 30 seconds to about 20 minutes for the reaction to
become violent. The 30 second minimum seemed like enough time to try the
reaction in a closed container and get away. Ha! What a mistake. I took a one
liter plastic soda bottle (Thank God I didn't use glass!) and added some brake
fluid. I then dumped in a couple of ounces of the calcium hypochlorite. I
immediately started to screw the top on, but in what was not more than a second
or two, the reaction went supernova. I threw the bottle (the top was only half
on!). As soon as it left my hand it exploded. I was engulfed in flames as will
as being hit by a spray of hot brake fluid and pool chlorine. My hand was fryed
from the heat and the sheer force of the bottle bursting within a few inches of
my hand. Its hard to describe exactly how close I came to having it blow up in
my hand. Not that it was much better blowing up several inches from my hand,
but it could have been worse. I was covered in pool chlorine and brake fluid. I
ran inside and hopped in the shower. After washing my clothes, they had a nice
acid wash/tie die look. In case you're wondering, I still have two eyes and 10
fingers. I feel very lucky.
