They still have a product page for it including lots of potential uses
but I've not seen a price.

Yeah, isn't compressed "air" actually propane gas or something weird?
Like, all you need is an ignition source and you've got your own
personal flame thrower?

Hairspray works wonderfully for that.

Or aftershave, or just about anything with a flammable propellant, really.
I still remember some doofus kid wanted to spray deodorant onto the
zipper of his jeans, ignite it with a lighter, and then I was supposed
to smother it with a pillow. So picture the scene: I'm standing there
with this pillow, the guy sprays his jeans, lights it, giggles, does
"arrr **** it hurts!", and I whack him with a pillow.
...still not *quite* sure what the point of all that was, but hey, if
some guy wants me to hit him with a pillow, I'm not gonna argue.

WD-40 gives nice sparkles in the flame :-)
More fun is a big super-soaker filled with petrol, although the end of the
nozzle kept catching on fire :-O

I'm surprised the petrol didn't disolve the plastic for a start...

Empty deodorant cans on the bonfire. The poor man's firecracker. Or full ones
for proper fireballs. Don't forget to stand behind something solid!

Guess they chose a plastic that didn't dissolve when in contact with petrol
(whether or not deliberately).
BTW most products that you might touch are usually tested against common
liquids you could have on your hand (sweat, hand cream, petrol/diesel,
cleaners etc) to make sure nothing bad happens.

Dude, are you tired of living or something?
Heh, and I thought *I* was crazy for using Al + KMnO4...

It can be dangerous, true enough, best not to do it anywhere near habitation.
Wooded areas are good, plenty of cover. Actually there's no real shrapnel... for
the regular two-piece can, the base usually blows off and one of the two pieces
will go flying. For one-piece cans like lynx, the entire can usually stays in
the fire. Usually :-\ Best to set them upright so the valve doesn't melt, which
can relieve the pressure non-explosively, so in a crevice between logs or
something. This also directs any flying debris upwards, making it (a little!)
safer. Can take up to 30 seconds to blow, even on a hot fire, plenty of time to
retreat.

The worst is when after 2 or 3 minutes it still hasn't blown, what to do?
Another interesting one is to put baking soda and vinegar into a bottle and
put the lid on quick (or use some cunning method to delay the mixing of
vinegar/soda). 500 ml soft drink bottles can take a huge pressure before
exploding!

I guess this is where I recount the tale my sister told me...
They're in a physics lab, doing some experiment to measure the latent
heat of nitrogen or something like that. Anyway, the experiment involves
liquid nitrogen.
One stupid decides that this nitrogen stuff is "really cool", so let's
take some home to play with. So he pours some of the liquid out of the
reinforced steel container into a small coke bottle, puts the lid on, and...
...well, the way my sister described it, there was a small bang followed
by a blood-curdling scream. All the staff rushed to the source, and
shortly afterwards a student was seen leaving the lab with shards of
plastic sticking out of the back of his hands.
I'm not sure what's more worrying - the fact that this was a PHYSICS
UNDERGRADUATE, or the fact that he attempted to deny putting the lid on
the bottle. (The lab officer gave him a kind of look like "so, what, it
just decided to explode BY MAGIC?")

I've never seen *nothing* happen... if the valve melts you usually get a whistle
or a woosh, then you have to decide whether to go back and knock it out and into
the undergrowth, or wait to see if it still goes up (can happen).
What to do... I recommend a riot shield! Or failing that, sturdy sunglasses, a
dustbin lid and a Long Stick.

Hmm, how much of the ingredients do you need? Some vinegar first, hold the
bottle on its side, pack the cap with soda and screw it on, shake and throw?
Or, you could contrive some kind of floating separator like a small piece of
clingfilm, pour in the soda, screw on cap, shake and throw?
I think shake and throw will be the modus operandi for this endeavour,
regardless!

Maybe we just didn't make our fires big enough first :-)

My friend had these small plastic bags that dissolved in water after a
minute or two (I think he used them for fishing somehow). We filled those
with the baking soda (a good few big spoons worth) and poked them through
the neck into a bottle half full with vinegar. Screw the lid on then throw
:-)

Hehe, yes it was one of the big important engineering puzzles we worked on!
We tried just wrapping the baking soda in clingfilm, but it was hard to wrap
it just the right amount so it mixed only after being thrown. That was when
we had the idea to use the disposable bags.

I've seen that done with dry ice and water.

We put a large squirty-cream can inside a stripped turkey carcass after one
gathering... there were bits of bone landing 100 yards away :-)

I think the best we ever did was drill holes in logs, stuff an M-80 tightly
into each hole, and toss it on the fire. It was pretty.

What surprised me was that the ridges, the inverted base and all the other
features in the plastic got pushed outwards, the outside of the bottle
became really smooth, and *rock* solid to touch (it felt like it was full of
concrete). We chucked it about a bit but it still didn't pop, so we put it
on the fire!
Yes I know this was ridiculously dangerous looking back!
