Excellent thought. This is perhaps the ideal match safe and fire-suppression grenade: it can be thrown into a conflagration, detonate, and spread fire suppressing bicarb, as well as provide enough fire creation supplies for maybe 300 camp fires.
(I attempted a google search to see how many fires a butane lighter will light. Came up dry, but discovered a guide to fire shaving: http://www.instructables.com/id/Fire-Shaving/?comments=all)-Blast, have you experimented (intentionally) with hair-removal by flame or explosion?

Fire shaving. Brings a whole new meaning to the term "razor burn"...

Back in grad school I used to do the demonstrations for the freshmen chemistry class. One demo was displaying ballons containing different gases and having the kids vote on which would give the biggest "boom". The balloons oxygen, nitrogen, helium, hydrogen, and a mixture of hydrogen and oxygen. After they'd vote I'd touch a match to the balloon.

Oxygen: pop
Nitrogen: pop
Helium: pop
Hydrogen: POP
Hydrogen + Oxygen: KA-BLAM!!!

The resulting explosion/fireball removed all the hair from my arm and the side of my head. Italso knocked my goggles askew and removed one eyebrow. The campus radio station was in the basement directly below me and the sound of the explosion was broadcasted (not intentionally) throughout the tri-city area.

The next time I did the demo I taped the match to a long stick.

And also used bigger ballonns.

Too bad halon is too toxic... Compress that into the space. ;-)

How about a co2 cartridge?

With the addition of highly compressed gas for this project (C02), we can now add fins to the project and turn it into a torpedo. No longer limited to snaring small animals, we can go after Shark, small boats, etc...

Now, if that's the plan, then don't we need to pack a strong oxidizer in with but seperated from all of those matches. A small charge at the point of the barrier between the oxidizer and the matches would provide both ignition and all the mixing of the oxidizer with the flammable material.

Blast, this may be something for you to try out. It sounds like it is right up your alley. Although, it had better not be in an alley that you try it. You'll need a big open space, and time to get away.

Uhm... yeah... that WOULD be illegal.

*shakes head, grinning* Silly, silly humans.

I'm not gonna tell you how I know this, but if you take an oxy-acetylene torch, get a good cutting flame going, tap the tip against a flat piece of steel to snuff the flame, wait a few seconds to let the tip cool, then stick it in the mouth of a baloon, fill baloon, tie it off, put the baloon in a paper sack, put the sack in the middle of an intersecton, set the bag on fire, and run like hell (VERY important), you can break windows on all four corners...

It sounds like you also had an interesting childhood.

Oooh...so beautiful. So very, very beautiful...
