A nice formula, but not practical from a household or OTC perspective.

I do like the cannon fuse idea. It might be a problem to EDC in places like Manhattan, where I would have some explaining to do if the constable or some such took notice.

There's lots you can do with the 4th of July goodies they still sell. Reliable and effective pryotechnics at an affordable price, like sparklers, punks, fountains, all wonderful little burning items many of which can be EDC'd easy enough.

Still the best for me is either some fatwood or coniferous resin, one of them trick candles, or them tinderquiks you can get at the sporting goods stores.
