How does the nozzle diffuse?
I would guess it's just a fine mesh that the liquid is forced through.

#12Wouldn't this design create a vacuum in the reservoir? Edit: (reservoir = bottle)
There is usually a small air vent into the bottle. Small enough that fluid tension stops any spillage even when turned upside down.
Because it is small you can cause the bottle to collapse if you do a lot of spraying quickly, an effect you might have noticed before.

#13Having source be in the "staging area" after "git add" makes more sense to me now :-)

#14A clearer title would be, ' How does a spray bottle work' I'm guessing the authors first language isn't English, but saying 'why' would be better suited to explaining why a spray bottle works for a certain solution or process. Why does a spray bottle work well for watering a plant? A spray bottle produces many small drops of water which is an effective method of covering the leaves of a plant.
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]?

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!

Thank you, I was also expecting that information, not an essay on small-scale ball check valves.

#16A very simple design, based on a principle that was discovered over 2000 years ago.

I wouldn't think so, that's how you go from spray to foam (e.g. some household detergents around here have a small mesh screen you can clip over the spray nozzle to get a detergent foam instead of the liquid droplets of a regular spray bottle).

#18This is a nice example to show the illusion of explanatory depth [0]. Most people would say they know how a spray bottle works, but fail to describe all relevant details of the implementation,

I think it's actually that the particles are forced to collide at relatively high speed due to the pressure behind the small opening. A mesh could eventually get clogged with minerals or debris, but this approach leaves less room for failure. Basically you're just ripping the fluid into mist with high pressure.

#20One way valves are basically diodes, but for fluids rather than electrons. You can also make logic gates out of just diodes (or one way valves).
Imagine writing software for a hydraulic computer!
