There's a good reason for that. It's a HIGHLY reactive chemical and produces incredibly toxic fumes no matter what you are doing with it. It is also a vital component for explosives productions, so it is highly regulated and closely watched. Whatever "home experiment" you're doing can be done using other commonly available acids like sulfuric acid or hydrochloric acid. Unless, of course, what you're doing is making an explosive. If making an explosive is what you are doing, then you will not get the answers here. We're here to help people learn, not become terrorists.
