Hi! I enjoyed reading your comment, but please be careful before posting working explosive recipes on the internet nowadays. It's sad that we have to think about it, but we do. (Unless you deliberately posted one that doesn't work, in which case, you got me :) )

Right, because if we hide the information then bad people won't have access to it. One of the first uses of the public Internet was to distribute text files with bomb recipes. That and porn. Cat pictures came later.

Potassium nitrate and sugar has been a very well known mixture for - what? Hundreds of years at least. We need a culture of rational and critical thought, not one that sequesters away knowledge.

"Rocket candy" is very widely known already, and HN is probably the last place terrorists will look. And terrorists won't use rocket candy. Hey, did you know you can react nitric acid with glycerin to get nitroglycerin?

  You can even react nitric acid with all sort of oily things such as benzene and toluene and get various explosive. Isn't that common knowledge? I remember being taught that in chemistry back in high school (nothing lights up interest of pupils in chemistry like things that go boom).

Technical aptitude and diligent study do not intersect with violent criminality very often.

  Ha ha, nice try. People in the UK get arrested for reading about those things. It does seem that those charged are usually guilty of some other crime, however. https://www.google.com/search?q=anarchist+handbook+uk+arrest https://www.google.com/search?q=anarchist+handbook+uk+arrest

it's probably alright as long as he doesn't tell ISIS the secret recipe for "red iodine" (aka "nuclear nitroglycerin") I've heard 'red iodine' is a long running troll the intelligence community plays on terrorist groups. They say it works; extremists say it works & you can't fool them out of looking for it!
