	It appears that at least in Canada, the Ammonium Nitrate
you get as fertilizer is the same as that you would get for
explosive purposes. I remember now that the AN I bought from a
feed mill was made by CIL, and is _exactly_ the same as the EGAN
which was described earlier - no coating, etc...

	Chris lives in the same part of the country that I do,
and he has had success with it. I have had success with it.
Therefore the conclusion is reached that FGAN is identical to
EGAN in Canada. Hurray!

My grandpa had one on the farm...some sort of automatic cannon that
would go off every 5 minutes or so to scare the birds off fresh seed.
It was pretty loud, like a shotgun going off.

Contrary to popular belief (at least the people i've talked to) flame does
not usually travel down tubes and into the liquid, as in hairspray,
spraypaint, WD-40, or over-lit lighters. The cause of the explosion, is
probably caused by the heat of the flame conducting down the rounded metal
piece. The one that holds on the wheel, shields the flame from wind, keeps
people's fingers out of the mechanism so they don't turn the gas too far
up.. Any way, the heat goes through this, melts the plasic, and the pressure
in the lights makes the soft plastic bulge and rip. Since the lighter was
"on" all this happy newly-liberated gas just can't wait to ignite.

A Chemical Kiloton Experiment
at the Nevada Test Site

The Lawrence Livermore National Laboratory (LLNL) will conduct a large
chemical explosion (CE) called the Chemical Kiloton Experiment (CKE) in the
Rainier Mesa area of the Nevada Test site. The explosion will involve a 30/70
Emulsion-to-ANFO blend of 1,147,000. kg (2,536,000 lb) to supply 1 kt, and is
scheduled to occur approximately January 29, 1993.  It will be heavily
instrumented with close-in free-field, surface seismic and regional seismic
measurements. The CKE is located near several DNA sponsored nuclear
explosions (NEs) and will provide a unique opportunity for fundamental
studies such as explosion phenomenology (e.g., CE/NE equivalence), scaling
with CEs and NEs, and integration of multiple monitoring methods. This
experiment will also address some critical proliferation monitoring problems
such as CE masking of NEs, CEs as false alarms, CEs for regional calibration
and on-site inspection.

Participating organizations include LLNL, Sandia National Laboratory, Los
Alamos National Laboratory, Phillips Laboratory, the University of Arizona
and the University of Nevada, Reno.  Other technical organizations are
welcome to field recorders, analyze the results and contribute data to an
integrated data base.  Those who are interested in more details regarding this
experiment should contact Don Larson of LLNL at 510-423-5162 or Fax 510-
423-4077.  A meeting to discuss the CKE is planned during the Annual AGU
Meeting in San Francisco. For those interested in more detail about the
experiment, please check the AGU announcement bulletin board at the
conven-tion center for time and location.

The data from this experiment will be available via an integrated data base
which is being coordinated by Eileen Vergino of LLNL. Questions regarding
the data base should be directed to Eileen Vergino, 510-422-3907, Fax 510-423-
4077 or E-mail verginoes@llnl.gov.

Right. How much have you read about the, so called, war on some drugs?
There are many houses etc broken into by accident - where the people in

police have shot innocent people. 

I feel sorry for anyone who is being stomped on by a repressive government.
Unfortunately, most people do not realize the current problem, until they

I was informed recently that when you hold the flame on the BIC

too long that they have the tendency to explode.

TRUE? (I'm about to go try it this weekend, I'll tell you when

More importantly, is it true that the cause for this would be
that the flame travels down the little plastic tube and ignites

As I posted in another thread. All the varieties of fog oil I have seen are

I recommend a person use the machines, rather than create smoke or fog by

	I had a bunch of military devices called "Thunder
Flash". They were the same colour and size of a stick of
dynamite, and were ignited by striking it against a rough
surface, or a built-in striker. It was used as a close-quarter
stun device. Basically it was just a large firecracker.

Yes it is illegal to threaten anyone with harm.  But you can safely joke

nitrate as an explosive: It will work, but not as efficiently as
explosive grade ammonium nitrate because of the porosity. He

For that matter, how about silver acetylide?  An acquaintance once told me
he made the stuff simply by bubbling acetylene gas thru silver nitrate and 
collecting the precipitate.  He said a piece the size of a match head ex-
