Even if not, this could start a huge pissing match between you and your neighbor that might not end well for you Buffalo Bills Mafia means family shirt. Also, throwing water on a dog once or even a dozen times will not make it stop barking and could even make the dog bark more. She’s probably barking because dogs are social animals and her pack leader (human) won’t let her inside which makes her sad and lonely (and maybe bored especially if she doesn’t have any toys outside). Not that it’s easy having compassion when you just want peace; I know there is little more annoying than a dog who constantly barks when you are just trying to enjoy some quiet, but reminding yourself of this may change your outlook on the situation.
There are several companies that make these sonic birdhouses that emit a tone only dogs can hear that are supposed to prevent dogs from barking so much. I haven’t used one, but they have pretty good reviews. If this is happening only when you are outside you could also try to listen to music or sounds designed to block out noise (usually rainstorms or ocean sounds) to drown out the barking. I have known people who had good results with dog whistles, but these were with their own dogs, not a neighbor’s. Say you did get on a rocket with super-insulating and reflective material that would allow you to approach the sun, and throw or spray water towards the surface. Not to mention that before reaching the surface it has to pass through very hot gaseous matter. Theoretically, it would turn into superheated steam in no time then continue to split into hydrogen and oxygen. Then oxygen may combust if ignition conditions and met and cause a small explosion.
