The common culprit in these were the teflon coated burner pans popular
some years ago.  But it is well known that burning a teflon frying pan
will kill your pet birds.

The Hercules plant is the one that blew up nearly destroying my cousin's

small and the third was the largest.  One man was injured/killed when
the first explosions got him up and looking out the window, then the last

I made an easy and cheap digital timing igniting system.  It involved a
kitchen timer and a 6 volt battery, a filament made with a thin strand of
copper wire ound around a pin and a homemade firecracker. Also a good
transistor might be needed also. If you know anything about electronics
you should be able to amplify the signal (kitchen timer) output using the
transistor hooked up to the battery.  The filament heats up cherry red
when the current goes through which ignites the firecracker or any other
heat sensitive explosive.  One point though.  You are short circuiting the
battery through the transistor and the coil.  Make sure you get a high
enough rating on the transistor so that the coil will glow REAL hot before
the transistor blows.  How to time it?  Well, I guess you can figure that
out.

As for your radio control device;  easy enough.  Go buy yourself the
cheapest radio controlled toy you can find and dissaseble it. Again, if
you have any experience in electronics you should be able to use the coil
system since the control unit allows current to flow through a circuit
when a signal is received.  Got it?   I prefer going with fuse though. 
Cheaper, easier, and I don't plan on planting bombs on anyone which these
methods of iginition would be ideal for.  What do you want to set off anyway?

Here are some suggestions from the model rocketry world:

- One of the model rocket manufacturers is about to release an IR remote
  wireless launch controller (North Coast I think)

- Many people have used modified radio-shack timers (kitchen timers with one
  trace cut on the back and an SCR added to drive the pyro devices) check out
  back issues of High Power Rocketry for circuits (it was recently reprinted
  with an eratta).

- Other people have used off-the-shelf R/C systems with servos driving
  micro-switches to trigger ejection charges. I use a servo replacement
  circuit that drives the charge directly.

None of these counts as 'pre-made', although the timer probably comes
close.

Hi,

   I'm interested in making thermite and wanted to ask the
experts about the hazards involved.  The FAQ mentions the
potential respiratory problems posed by exposure to fine
powders such as those used in thermite.  It also warns
of blindness from the extremely bright UV light that's
released.  Of most concern though, is the warning about
spontaneous ignition of Al dust.

   o Are there any preventive measures?
   o Will Al treated with stearic acid be more stable?
   o It sounds as though significant activation energy
     (ie. a sparkler) is usually required.  If the Al
     can spontaneously combust though, can the reaction
     itself proceed spontaneously and rapidly?
   o If not, will the reactants slowly combine and diminish
     in potency?
    
   The FAQ mentions that this is an oxidation/reduction.
Are there two exothermic reactions or one?  Exactly what
is going on here?

   o What are the reactants and their charges?
   o What are the products and their charges (if any)?

   Thanks in advance for your advice!

Granted - I am not up to date on the latest research. However, this is
the first time I have heard of this.

Being a fluorine donor, it could be used as a color enhancer. I do not
recall any formulas that used it for that. I expect that it would be
rather expensive for such a purpose. I found a couple of vague references
to the military using it in infrared flares.

A good flash composition does not need a sturdy case. Teflon would just
be an unneeded addition.

It is still being argued whether flash mixtures actually detonate - at
least, in smaller quantities. Maybe someone else will have some cites
on research which has been done recently to settle this question. Dr.
Shimizu seems to indicate that our normal flash mixtures detonate when
initiated by a strong enough blasting cap. He also indicated that large
quantities will detonate, when ignited.

The aluminum is grabbing the oxygen from the metal oxide.

There are many combinations of metal oxide and aluminum that
are possible. 

The resultant products are basically Al2O3 and a reduced metal.
Impurities remaining depend on the mixture proportions, as well
as the efficiency of the reaction.

Note that magnesium will do the same thing. It is just more
expensive, as well as being more hazardous to work with.

This isn't quite a munitions plant accident but some fool here in San Antonio
was cutting a hole in a 3000 gallon gas tank.  He thought the container was
empty and had supposedly been fume tested.  Well, it wasn't.  The explosion
blew out windows and doors in a 5 block radius (about .75 km)  The cutter was
uninjured(what a miracle)  but the trailer and truck that the tank was on
was pretty well destroyed, i.e. all the glass was gone and the cab was badly
bent.  The tank was knocked off the truck while one end of the tank was
launched as a projectile, tearing a big hole in the roof of a quonset-type
building.

A joke I made up of this accident is:

Did you hear about that guy that caused the explosion?  Yea, he blew away his

	Don't recall a fiure off hand, but solder will melt somewhere above
