Likely used only as a sapping method, set off a small one to attract attention, then use a much larger explosion to take them all out. If you can do it before they shut off the gas, all the better. Gas leak and cornmeal bomb as demonstrated by CSI. Granted Hollywood is Hollywood, but 'tis still plausible.

"Take a piece of aluminum and file it. "

Or filing a piece of aluminum piping/a slab of aluminum. A trip to the chemistry store is always useful for getting chemistry ingredients as well. ;-)

It's not recorded anywhere, but I'm sure that explosives synthesis is still taboo to post on here.

However, there's no good reason for there to be any trouble if you should write up that information offline and upload the document to Mediafire or 4Shared or something like that. Don't attatch it to this page, though; it should be completely external in those regards, and don't post the information itself on the wiki; just the link.

And. . . Well, please write the guide only if you're quite knowledeable in the manufacturing of explosives. The last thing a survivor of an apocalypse needs is misinformation that'll get them killed, and there's a lot of that to be found on the internet and in many common guides. *cough*AnarchistCookbook*cough*
