This 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,

One 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!

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

What I find most frustrating about the current class of spray bottles is that they've removed the ability to unscrew the head, and therefore you can't a) get out the liquid which can't be sprayed, or b) reuse the bottle.

It's a simple mechanism, but the writing and diagrams deserve an A+ for clarity.

Wouldn't this design create a vacuum in the reservoir?
Edit: (reservoir = bottle)

I found his write-up on MBTA bus mirror positioning to be a short but interesting read as well: https://alexanderellis.github.io/blog/posts/mbta-bus/

How does the nozzle diffuse?

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

If anyone's curious for more, look up how an atomizer works. It's simpler but requires more background knowledge (namely, the Bernoulli principle).

I know why I clicked on this; one of my cleaning spray bottles just broke. What's everyone else's excuse?

I was literally just thinking "how does this work" when looking at a spray bottle yesterday. Thanks!

This is cute and all, but still silly. At least, for those of us whose childhoods included dependence on wells with hand pumps. Or particularly, responsibility for maintaining said hand pumps. Because it's an ancient design. Old ones used leather flaps as one-way valves. Same for tire pumps.

The spring might be the reason why a spray bottle doesn't last very long if you re-fill it with a bleach solution, when it was not designed for it?

Great write-up, awesome diagrams, some parts could use some improvement in language, but the diagrams more than make up for it.

A 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.

Instead of a normal plastic tube inside a bottle with an opening at the end, he designed a tube with millions of tiny perforations along its length. This meant the spray bottle could operate at any angle (even upside down) and could empty all liquid in a bottle with no leftover.
Here is a 1 min demo of the spray: https://vimeo.com/195318537
Here's an explanation of how it works https://www.youtube.com/watch?v=xXk46rvzdpY
And here's the original pitch he made on Dragon's Den https://www.youtube.com/watch?v=RjOvyjeZyIw
