Writing Excuses Season 3 Episode 3: Stumping Howard at Conduit

Howard here... I've learned that it's a really bad idea to run out for a bio-break between podcasts. When I returned to the packed panel room I could tell that everyone's attitude towards me was subtly different. It wasn't until we started recording that I realized Brandon had turned our Q&A panel into a "Stump Howard" panel. Our good friend Eric James Stone joined us for the fun. As silly themes go, this one works well. So well, in fact, that we went six minutes into overtime. The questions were all good, and yes, according to the rules (of which I was not apprised, I should add in my defense) I got stumped one time. It was the question about making aliens seem alien. Go figure. Writing Prompt: Start with a device that vaporises water, ala Batman Begins, and turn it into a believable superweapon which is not being used to destroy the world.
