Like others have said, it's like following a cookbook. Cabin, basement and mountain dwellers alike cook up high explosives via watching shitty step-by-step guides someone recorded in their basement, reading text files written by wannabe anarchist teenagers and PDFs of books written by Jimbob McCletus in bumfuck nowhere back in the 70's (and lovingly published by Paladin Press), so school ain't shit, as long as you learn the information somewhere.
That being said, the real challenge would be getting the chemicals and equipment.
