If the cup is taller than 34', then it will start draining as usual when overfilled. However, it won't fully drain, but will stop draining when the free surface reaches 34' below the top of the siphon.
@@Bitmaker64 well not exactly 35 ft as it is artificially increased by using water tanks to increase the pressure of the flow of water to the toiletries, it's exactly how you get skyscrapers which have siphon based mechanisms for their toilets and showers working for you, the siphon based mechanisms are exactly how the Pythagoras cup works but here there are multiple 30+ feet cups attached to each section of the building for them to work

@@FaTALiNFeRN0 iirc they can always hand it off to a different straw.

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.

3:35 probably still gonna work just not as well as it would have, because it’s not just pressure/suction at play here but also gravity/momentum, which will probably be just enough extra energy in the system to have it work for at least a little bit!! :D
I kind of want to replace the mugs in my house with this when my inlaws are here. For some reason they have this weird habit of filling their cups all the way up the rim so that it almost spills over. Like it is so full that they have to walk slowly so it doesn't spill and sometimes it ends up spilling anyways because they're so full. It is annoying and I don't get the behavior at all.
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.
Comments like this are the reason I'm subscribed to this channel....if I don't learn something from the video, I come down to the comments to see intelligent questions and comments like this❤.....cheers man, I hope he responds to the question
Well, it is just as he said: the hydrostatic pressure of a liquid depends only on the height. "The pressure exerted by a column of liquid of height h and density ρ is given by the hydrostatic pressure equation p = ρgh". That's all the math you need.
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.
This is exactly how a pipette washer works. Essentially you keep it 90% full so the pipettes don't break when you drop them. When you're ready to empty the water you fill it just a little bit more. Like you're handle there is a little U shape rube on the side.
I have printed this design with my 3D printer and it needed supports. It is a pain to get off of the cup, can you post a video that shows how you got the supports off?
3:35 My guess: it would still work, until the open region of the cup is (almost?) drained, because in addition to the atmospheric pressure, the column would be pushed by the pressure of the water in the cup
3:40 think that it would work because the siphon’s maximum vacuum is 34 feet, so theoretically it should work if you try hard enough, also after the the water reaches 34, it will decline in altitude due to gravity.
@@katrinabryce Lifting a liter of water 10m takes 98 joules. Boiling a liter of water the standard way, at STP, takes 330,536 joules, it's orders of magnitude less.
@@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)
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.

3:40 I think it will initially work until enough water is drained to where the pressure reaches 0.03 atmospheres at the top then the siphon will work slower possibly gurgling and eventually stop. I think the siphon tube will not empty though, I think it will keep water in it as water tension will prevent air bubbles entering from the bottom(to a point) exactly like a straw that you trap water in with your finger, if you turn the straw sideways it will drain but until then the water stays trapped, even with an air bubble above the water line EDIT: HAHA! I was correct! at 7:04 you can clearly see there is still water in the siphon pipe!
I'm curious, ...it would seem that the volume and weight of the "fluid" in the "cup" would also potentially play a factor, too, beyond "amospheric pressure", (one amosphere, on Earth, = 15psi, at sea-level). If this isn't the case, then why??? 🤔🤔🤔 (The reason I said "fluid" is while water is used in you example, there are many fluids that are less, (or more), dense. And, there are also fluids greater, (or lesser) in weight. So, it would be interesting to explore how and if they would change the outcome.
3:40 i know that for trees a similar thing works beyond 10m cause pressure inside water can get below 0atm, if no air,.. os contained. So i go with yes.
It is because the suction of the water that has left the system is gone out of the pipe. If you have an extension to the exit pipe it will drain the whole thing no matter the height.
@7:00 couldn't this length be changed by altitude since it takes less energy to reach vapor pressure at a high altitude. But if youvwere in a mine or death valley the vapor pressure would require an even longer straw
I tried to show my wife this vid on Apple TV but she thought your yellow snake shirt was 'don't tread on me' or similar and told me to turn it off. Just FYI.

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?
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

3:43 I’m going to guess that the water will boil to try and let the overflow water drain out.
3:40 I think it will initially work until enough water is drained to where the pressure reaches 0.03 atmospheres at the top then the siphon will work slower possibly gurgling and eventually stop. I think the siphon tube will not empty though, I think it will keep water in it as water tension will prevent air bubbles entering from the bottom(to a point) exactly like a straw that you trap water in with your finger, if you turn the straw sideways it will drain but until then the water stays trapped, even with an air bubble above the water line
EDIT: HAHA! I was correct! at 7:04 you can clearly see there is still water in the siphon pipe!
This looked incredible! Your videos are always so interesting!
And that, kids, is why less is more
I'm curious, ...it would seem that the volume and weight of the "fluid" in the "cup" would also potentially play a factor, too, beyond "amospheric pressure", (one amosphere, on Earth, = 15psi, at sea-level). If this isn't the case, then why??? 🤔🤔🤔
(The reason I said "fluid" is while water is used in you example, there are many fluids that are less, (or more), dense. And, there are also fluids greater, (or lesser) in weight. So, it would be interesting to explore how and if they would change the outcome.
Cover up those holes😂 1:59
There’s too many
@ use something to cover up all those
@@rhodesraisor3453It’s a waste of time…
@@Staggeflywhat time would you have??

When you put the cup down it stopped so use a straw
Just put your hand over the top or a piece of cling wrap.
ok but you cant drink it if that happens.
@@draconicdestruction5352 you could still poke a hole through it and use that for a straw and seal tightly around the straw.
3:40 i know that for trees a similar thing works beyond 10m cause pressure inside water can get below 0atm, if no air,.. os contained.
So i go with yes.
“Was this a planned event?” “Yes”😏😏
It is because the suction of the water that has left the system is gone out of the pipe. If you have an extension to the exit pipe it will drain the whole thing no matter the height.
7 minutes in and the comments section already has 4 bots
Even more now
thats how bots work
this channel is new myth busters for me 🤘
“Could I have a drink?”
Pythagoras: “Sure, but not too much or else the water will run away”
Assuming the water being poured in the cup will push rather then the air pulling like the straw it should always work
Did he just drink the blue water? 💀
Tastes like water. And blue. Of course
its just water with food coloring 💀
All water is blue! Very slightly blue
Yes!! This was filmed directly ON the flight, on the way to the shoot. It was the only source of bulk H2o that they had. XD XD
@@gavinjenkins899 You might want to google that before saying it :)
It is one of the most useful designs of all time. It's also called a flush toilet.
Calling it right now it’s not gonna drain
“what is this a planned event?”
“yes” hits hard
Is this how toilets drain?
😂
Yup
2:30 what if you tilt it and goes down?Will it be able to do that
Also me: *tilts the mug forward slightly so the drain point is higher than the edge of the cup*
If you tilt the cup you can't fill it to the brim either, the cup seems pretty generous until you fill it way too much
@@enderyu It's not about getting more liquid into it. It's about filling it above the line and not triggering it
@@HyperScorpio8688 The point is you can't "fill it above the line" if you tilt it.
@@enotdetcelfer There is probably some way, I'm just too tired to give serious thought to it
@7:00 couldn't this length be changed by altitude since it takes less energy to reach vapor pressure at a high altitude. But if youvwere in a mine or death valley the vapor pressure would require an even longer straw
I tried to show my wife this vid on Apple TV but she thought your yellow snake shirt was 'don't tread on me' or similar and told me to turn it off. Just FYI.
If a pythagorus cup and a Klein bottle had a baby, it would be a perpetual motion machine.
I hate when I get too greedy and my mysterious blue beverage begins evacuating through cleverly hidden openings at the bottom of my mug
If I'm treating someone to a drink, I want them to feel comfortable to enjoy at least ONE full cup.
These cups are for people who are cheap, not generous. (The liquid is usually the cheapest part of the product, in any case.) Treats are humbug, Crachit!
@@dylanlamarre3768 Reverence your refreshments with fear and trembling! 🤣
This guy is the cooler Mark Rober
Couldn’t this theoretically be implemented in boats/ships in order to prevent from sinking if it begins to take on water?
Imagine waking up at 7am on a Saturday and this guy is outside of your apartment on the 3rd floor enthusiastically doing this experiment
Man, if I'm your neighbor in that apartment complex, I'd watch you all day doing science stuff!
0:03 the cup rlly said:”I cannot hold it in anymore”🤣🤣🤣
I want this for my stepmother. She always fills the glass/cup to the maximum top.
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. 😅
either he owns the building or he is that weird guy in the neighborhood
At 07:17 is the water really boiling? Why did it start boiling?
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
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?
