With regard to chemicals, may I suggest a perusal of the PGI and PML lists (respectively, Pyrotechnics Guild Inc. and Pyrotechnics Mailing List)? These are good resources; just about anything you might want is available. However, they are serious; the KeWl BoMb stuff is on USENET (attn: C'Punk Newsgroup folks-thanx Dimi--there *is* a difference). Yea, (as D. Thorn might babble, if I understand the shards of his stuff quoted in the posts of those who should know better) when I was a young fellow, the guy at the local chemical supply co. asked my mom, "Lady, do you have any idea what metallic sodium and red fuming nitric acid and Willy Ley-strength Hydrogen Peroxide are all about?" Me, personally? I'm glad to have traded the availability of interesting reagents for the "Oppa-tune-itee" of having freedom and justice. (Although nobody "axed" my opinion prior to there having been a reversal in the thrust of gummint regulations.)
