Re: Why does a spray bottle work?
#92A few years ago, a British inventor appeared on a TV show called Dragon's Den (UK version of Shark Tank) and pitched his idea of an improved spray bottle called the Anyway Spray. 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 al…
I have a spray bottle that I bought to clean windows, because it can shoot a stream about 20 meters which is great. It is also labeled "sprays upside-down!" which is really misleading. I thought it sprayed in any orientation but it doesn't. It only sprays when held straight up or straight down. There's an inlet on the base of the handle for the inverted case, and a valve that prevents the main pickup from drawing in air.

That’s not “really misleading,” it’s “barely misleading” or perhaps “slightly misleading.”

#94This 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, [0] https://www.edge.org/response-detail/27117
I think how trains stay on tracks [0] is also a good example of this. [0] https://www.popularmechanics.com/science/a25581/science-behi...
Yes! I coincidentally just learned about that topic recently.
What’s great about that problem is that it isn’t obvious that there even is a problem in the first place. “How do trains stay on tracks? Well... they have wheels, don’t they?”
Then when the problem is explained, it sounds impossible. The solution you first think of is probably wrong.

Cool. Looks like the guy got his stuff into products. He got raped by the investors in my view.

I noticed the video described him as MBE, so I looked him up. He also invented a water filter and was named Member of the British Empire for it: https://ideas.ted.com/since-the-ted-talk-michael-pritchard-o...

Why isn't this in everything? I'd easily pay an extra few cents to have this in spray bottles. It's such a frustrating problem.
In my quick analysis (could be mistaken, I welcome corrections), if this is one-time disposible then it only makes sense if the value to the consumer of the amount of product not thrown out as a result, is less than the extra cost of licensing and manufacturing this and this cost can be passed onto the consumer somehow. In other words, if this costs 5¢ more then it is worth spending an extra 5¢ on if you keep from th…
It's nice that it would end up using all the product but I'm thinking more about convenience. I often hold a bottle sideways and, while there's plenty of liquid, I can't get the spray to work in that orientation. So frustrating.

That episode of Dragons Den is infuriating. Here is a guy who has invented something with a widespread, common appeal. He invented a product that potentially fixes a real problem in 1,000,000,000 units per year and he has to give away 20% of his invention to get support.
He had the option to reject the deal, no? It's a free market for venture capital, so if that deal is so bad and the opportunity is so good, he should have been able to find a better one.
From my perspective, having a great idea is not enough. Even having a proof of concept is not enough. There's a lot more that goes into building a successful business. Investors have to price in the chances of all the things that can go wrong in the process against the perceived value of the product.
Likewise, as a founder, you often need at least some investors that can help propel you forward in some way. That can be worth a lot more than dumb money.
I haven't watched the episode you mention, but generally this is how I think about it.

If it was simply perforations, it wouldn't work when the bottle is upright because those perforations would let the air into the top of the straw. Rather, the straw is made of a membrane which lets water through while blocking gas.
You need to let air through or else it creates a vacuum. What's happening is it just slows the flow of air enough to be able to get suction from the fluid. Having fluid in the tube also helps.

#100I know why I clicked on this; one of my cleaning spray bottles just broke. What's everyone else's excuse?
