I read a hard copy that was passed around my high school in the early 90s.

The only chapter I remember was the one about tamping explosives in order to concentrate the force of the blast in the direction you want. That was really interesting to me for some reason.

Slightly veering away from the subject. But your comment reminded me of 'The Little Red Schoolbook' --which was the [supposedly banned] book that we all passed around in school. Although being sadly older than you, this would have been the early 80s. I wonder if anyone else remembers it?

As I recall it was pretty subversive in content, with sections on sex, drugs and anrachist politics.

EDIT: Seems it was quite well-known after all. Wikipaiedia has an article on it:
