tons of chem books everything and anything you can find.
Read organic chem, inorganic, electro chem, patents, research papers, army field books such as FM 31-20, and the back of everything in the local stores. also reading things on pharmacology does help, though it is for drug chem.
edit: don't say fucking bombs idiot. It just shows that you want to kill people, and destroy property that is not yours.
