What starts out as a report on safety in underground labs quickly turns into a thick repertoire of synthesis sketches. Very informative, especially for beginner amateur chemists, as an overview of possibilities. Includes 'A list of homemade explosives and the chemicals used to manufacture them is presented in Table 1'.

Very informative website. Of course the information is nothing new to me, considering my website, but others may find it of value.

I would not mind trying out the PEAC tool they talk about here: http://www.aristatek.com/explosions.aspx
