Yeah, the thing about "home-made" explosives is you dont know WHAT is going to explode.
For instance: the easiest method to synthesize nitrocellulose (aka "guncotton") was discovered by accident when someone used a cotton apron to wipe up some nitric acid.
Everything *seemed* fine until the apron exploded after being dried.

...Around 1846 Christian Friedrich Schönbein, a German-Swiss chemist, discovered a more practical solution. As he was working in the kitchen of his home in Basle, he spilled a bottle of concentrated nitric acid on the kitchen table. He reached for the nearest cloth, a cotton apron, and wiped it up. He hung the apron on the stove door to dry, and, as soon as it was dry, there was a flash as the apron exploded.
