improvised trench grenade
So I have a character who's good at making homemade explosives and stuff. I want to write it realistically, so I have to look up how to make this stuff, but I don't want the feds to come knocking at my door. I know it's not 'illegal' to look this stuff up, but will I be put on a watch list or something? I swear I'm a nice person I'm just a writer.
