Author here, thanks for the feedback! English is indeed my first language, but I am always looking to improve. I chose "Why" for reasons similar to what jstanley wrote. When I was first considering the mechanism, connecting these components by simple tubes seemed like it wouldn't work. Why then did it work? Why does a spray bottle work [when it seems like it shouldn't]? vs. Why does a spray bottle work [well for watering a plant]? I saw that sctb temporarily changed the title to "How", but it looks like we're back at "Why". I apologize if any readers were expecting a more metaphysical discussion about spray bottles, but I'd be more than happy to explore that in a future post!
