For example, I learned that you can make a low explosive (that's a technical definition, it would be similar to the black powder used in quarrying) from ******** and any variant of C6H22O11, both of which can be found in most homes or can be easily obtained. Or you can cause another, more powerful, explosion by harnessing the power of xxxxxxx -- an explosion powerful enough to wreck your house.

Please note that I have left out the names of the active ingredients AND how to make/use the things. And I ain't gonna tell you -- you'll have to take my word for it. Gnu's all too eager to make things that go BANG!
