Not quite true.  There are smoke grenades sold for paintball games that can
produce a large volume of smoke quite quickly.  There is even one company
that makes a 'cold' smoke grenade - cool enough to hold in hand while going.

After reading this thread and seeing this post, I can keep silent no longer.
Acetone Peroxide (commonly called Peroxyacetone) is ***extremely*** unstable.
According to the Handbook of Chemical Demonstrations (the author's name eludes
me for now - it's designed to provide chemistry instructors with exciting
chemical demonstrations), Peroxyacetone is nearly as sensitive as NI3.  It
can be set off with flame or an electric charge.  It is also highly shock 
sensitive.  I have set small (~ .25 g) batches off with flames (candles on
yardsticks) and the results are quite impressive.  
  It is very simple to make, except that the reaction is extremely slow 
unless it's catalyzed.  The problem with catalyzation is that not only is the
synthesis catalyzed, but the decomposition is too.  The pure stuff is not just
terribly foul, but if there is *any* impurity, it can detonate (!) without
any warning.  

  (this seems like ample background to get to my point)

  Back in my wilder days in high school, I worked with this stuff extensively.
I had devised a wonderful "fountain" with a paper tube, some cotton and some
peroxyacetone.  I will not get into the details, because I have seen what
happens when these go wrong.  The one I was working with had about .1 g
of peroxyacetone in it.  I was getting it prepared to fire.  I set it in the
(shatterproof) fume hood in my lab and turned around to get my igniter to set
the fountain off, when it exploded behind me (at about 3 feet range).  
  In a nutshell, with .1 gram of the stuff, I was deafened for about 2 hours
and had it been in my hand, I would not have a hand today.  I still have not
determined what caused the explosion, but there was nothing left of my fountain
(or the clamp that held it) to start from.     
  My chemistry teacher and I concluded that it spontaneously decomposed (as
it tends to do occasionally). 

  Ever since this incident, I have not touched the stuff, and will not again
(even in such small quantities).  Peroxyacetone is as unstable as all
the literature says it is.  Be careful with it.

Yea, it is.  I have to corect myself on that one.  It's really Nitrogen
trichloride that is produced.  And it is very unstalbe from what people have
tald me.  The strange thing is that it's a liquid (oily substance).  If chlorine
works, then florine might work as well.  But i'm not sure that it will still

Whoops.  You're absolutely right; Li would be better.  I am abashed.  I grovel

It's more efficient to powder it than to melt it and then make it into an
aerosol--just melting something doesn't increase its surface area.  Or am I
missing something?

LF2 is cold, colder than LO2, though not as cold as LN2.  You will find it a
wee bit difficult, I suspect, to keep your cesium liquid; even if the
container is well-separated from the LF2 container (and it'd better be), the
tubing or whatever that combines them at detonation time will get cold,
causing potential clogs in the cesium supply line.

Of course, lithium is much easier to work with, as well as being more bang to
the ounce.  Make sure you don't breathe in any of the powder, though; it's
very, very toxic.

It's the LF2 that's nasty--fluorine reacts with *anything.*  Utterly
impossible to store for more than a few minutes.  You'd have to keep it in the
form of HF, which is marginally more manageable, then condense and electrolyze
right before adding the lithium.  

(I didn't think I'd have to point out that I wasn't serious....)

Well, well, well, maybe natural selection is about to have its evil way
once again. There are two different types of acetone peroxide. I will
assume that you are producing acetone triperoxide. Having just returned
from the library after having checked this very substance in Fedoroff
and Sheffield, "Encyclopedia of Explosives and Related Items" (among others),
I can say that acetone triperoxide is considered the MOST sensitive
initiating explosive available (around 11cm for a 500gm wieght in the
drop test if I remember correctly). This explosive is also extremely
friction sensitive. Apart from its hypersensitivity it is also volatile
at room temperature and so is not used in any commercial or military 
application. As for the hand trick, there was also mention that while
small amounts merely burn if unconfined, larger amounts can DETONATE.
(say goodbye hand!). Acetone triperoxide is classed as a Primary
Explosive and as such should only be made or used in SMALL amounts.
I have had much experience with another organic peroxide which is
less sensitive and less volatile (HMTD). This is a very powerful
PE and initiator (I inadvertently disintegrated a 4 gallon plastic bucket
with a small cap containing no more than 1gm HMTD immersed in water).
Due to the reported sensitivity to various metals and its high 
sensitivity to shock, friction and even pressure, I have given-up
using it. While I have never experienced any problems with this
chemical, there are numerous reports and stories of accidents with
it, that make it too unpredictable to safely use. The same goes 
for acetone triperoxide and even more so. With explosives you can
never be too careful. Just because it has never misbehaved as yet,
doesn't mean that in some future application, it won't suddenly
decide to be unpredictable and shatter a few illusions.

BTW, apparently, acetone triperoxide is still sensitive when wet

   Since I've done this before I'll respond:

    The best way is the buy a 1/2" riser for the carb. which has a
    needle valve in it, then hook up your tank to a regulater which
    will allow a small amount of gas to flow for a limited amount
    of time. An electric button activates this process.

    I have heard that NO2 now has sulpher in it to prevent kids from
    inhaling it. It seems the sulphur in the combustion process would
    create sulphuric acid? Anyone care to comment? Is this true?

I have carried LN2 around in 2-1/2 gal plastic antifreeze jugs..
They are good for short time storage (20-30 mins).  The outside
frosts up and "self-insulates" somewhat.  A Rubbermaid thermos
or 5 gal cooler also works for longer retention times. LN2 is 10F
or so colder than LOX (around -312F).  You are correct that the 
plastic will become brittle when cold, but normal handling hasn't
broken any of them yet.  I would suspect that dropping one
would make it shatter as does about anything else soaked in LN2.

Outside of rapid boiling when first cooling  down a warm jug,
the LN2 boiloff rate is not excessive..  Looks like champange?

A couple of weeks ago, I was at a local welding shop (where my
refrigerant is made), and the employees cornered a large mouse in
the office area.  In the past mice/rats have gotten in the walls
and died, stinking for 2-3 months..  I went to the back room,
put about 3-4 gal of LN2 in a 5 gal Rubbermaid jug.. and went to
"fight" with the mouse.  Totally doused a 10' X 10' office floor with
LN2.. whole room fogged up solid instantly, whole floor was covered
with boiling LN2.. We busted 2 floor tiles (lots of popping noises),
but we got the mouse... froze him solid.  But is was fun.

Are you sure that is what you made? 

I guarantee, if it detonated, that you would not have any hand left. Even a
few milligrams of explosive can remove skin and flesh.

I am not sure what you produced - guess it is time to do some digging in

I know that a couple of us have said multiple times that this conference is

if they are on some of these 'Underground' lists, then the authorities
are also there and paying attention.

If people are smart they will stay clear of the bomb makers and their
type.  The ATF is in the process of cracking down and if you are in the way,
you will not be for long.
