If you remove all nucleation sites(places that catalyze phase transition) you can actually have negative pressure in a liquid due to the cohesive forces, this would allow for such a cup to have infinite high only limited by the cohesive forces!

how would you do that tho? conducting the experiment in a close to absolute 0 environment?

[@Dontlikeyellow]

@@Bitmaker64 well the main variable would be nucleation sites so using distilled water in a smooth tube is a good start. If that doesn’t work one could take inspiration from how trees pull water from soil as they actually produce negative pressure to transport the water up the entire tree!

Oh so that's how trees do it.

[@locutusborg13]

Now imagine what trees have to do when they are taller than that limit ...

[@FaTALiNFeRN0]

they actually use transpiration! trees like redwoods that are insanely tall basically evaporate water though their leaves to create a vacuum inside the xylem to pull water up higher than you'd expect because capillary action can't get water and nutrients high enough. very cool stuff and it gives a new appreciation for trees in an easy to understand way.

[@michaelsorensen7567]

​@@FaTALiNFeRN0 iirc they can always hand it off to a different straw. If a tree pulls it up 20' through one tube, fill a bunch of cells, and then they stick extra in a separate tube, that other tube can pull it another 20' to another dump, to send it to another bunch of cells that can then send it on....

pipe cleaners exist, just need the right diameter for the core and bristles. also could snake a nylon/stainless steel/other flexible thread through so you can pull and push the pipe cleaner. the inside of the handle being smooth would help prevent it from getting caught. not impossible, but it is extra work. somtimes you only need hot water and soap if you don't put some types of fluids in it. if a pebble got stuck in it, then yeah it would be practically impossible to get out. Only solution for that would be to put a filter on the inlet and outlets as prevention.

At 4:48 you said "Water pressure doesn't change depending on the width, only the depth." Which I understand and agree. I am curious how pressure behaves in cone shapes of various angles, but filled so the water level height is identical. Would steeper sides lead to increased pressure? Or does it not make a difference at all? Examples: The conical paper cups used at water coolers, but larger like a cone automotive funnel with out the nipple/pipe extension on the bottom. I would assume it doesn't make a difference but could still be fun to show the math behind it. Also, you remind me of what Gene Wilder would've been like if was born 50 years later and decided to be an engineer in California.

Most math guys would say that the graph doesn't go negative. But, for physic guys, realizing that negative pressure also sucks air, the actual graph can go under 0, just that the negative water content means it is filled with air. So after the water is drained, it creates wind in the structure for a while.

[@gavinjenkins899]

@@BenRichards7 Nobody said anything about getting more energy out of this system than we put in, we aren't building a perpetual motion machine, we are just trying to get salt free water. You'd still be putting about 300 joules in (30% efficient pump to lift with 100J) and the water falling back down could run a generator but also at 30% efficiency, so you get 33J back out. So we lost 267J to inefficiency. Realisticvally there would be no generator back down and we'd lose all 300J. But if it's way better than losing 330,000 joules, it's an improvement for making salt free water. Not for making a generator. I might be missing something, but more efficient ways to do a thing that still sue energy but less of it are commonplace. For example using a catalyst to speed a chemical reaction and at a lower than normal temperature. Or having a counterweight in an elevator (still lose energy to friction but way less than if you brute forced it with no counterweight)

[@dougaltolan3017]

I've been thinking of this for a long time. While he energy input is purely physical and can be done manually, there is a significant gap in this process. That is removing supersaturared feedstock. The point where the water boils would quickly become clogged with salt crystals and need the whole system draining and cleaning.

Can you make a video on- What happens then something emits colour. Eg- grass is green - what is the property of the material that causes grass to absorb red and blue light and reflect green light?

"What is this, a planned event?", is the most savage way to illustrate you're unimpressed

Bro sounded like kid Lloyd from lego ninjago trying to rob someone. 😅

At 07:17 is the water really boiling? Why did it start boiling?

[@Wataonvr]

I think it’s going to be big waste of water and it will not flow very well because it’s at max suck height but once it gets 5 feet lower it will flow normally 3:40

[@johndolenc7658]

3:41 tbh idk. I’d assume the siphoning n breaks, so it would only partially drain the cup in question.

WAIT THAT BLUE WATER’S DRINKABLE?
