There is also another thing that causes moving water to not freeze very easy, that he forgot to mention - friction heating. When water goes down a slope or falls, it releases potential energy (just like any mass going down will do). That energy will end up as heat in the water as it hits more water further downstream (at the bottom of waterfalls), rocks and other stuff that slows down the flow. A stream that loses for example 0,6 m of altitude per minute, at average will also give almost 100 W per cubic meter of water that's moving at average - that's quite a lot when the energy has to be given off to air (bad conductor of heat) that's not very far below the freezing point. In his demo, he used liquid nitrogen (that's extremely cold and can absorb large amount of energy in a short time from the water due to it being so much colder than the freezing point and being liquid and conducts heat a lot more than gaseous nitrogen). If he had put the pump or magnetic stirrer in the freezer, it's might not have frozen at all (even if being left there for a week, haha), since the pump or stirrer heats the water enough to never get cold enough to freeze. In your case if you have a fontain pump - all of the power coming from the pump will end up heating the water (water it,s pumped up, it gets potential energy, that is then turned to heat at the bottom of the waterfall). That may be enough, for it to never get cold enough to freeze.

Is it weird that my first thoughts upon seeing this extremely white ice is what a great cocktail ingredient it would make. Like, generally in cocktails we like to use differential cooling to get extremely clear ice, but if you managed to quickly cool water in a high-pressure environment of smoke, or some other aromatic, you could get lovely milky white ice-cubes which as they melt slowly incorporate another flavour into the drink, adding a really long-term evolution to a cocktail.

Probably the hardest part of that, would be removing the regular gas, to make room for it to absorb anything else. So put it in a vacuum chamber to degas, already very cold, then take it out and put it into a pressure pot with something smoldering inside and pressurize it to force as much of the smoke in as possible, while bathing that pressure pot in liquid nitrogen. Not sure if the stirring helped or hurt the cause, probably hurt, so it would be better to allow it to be still.

[@Nofxthepirate]

One of the coolest things I learned in physics class was that a substance only increases in temperature between phase changes. Once a phase change "wall" has been reached, the entire substance has to change phase before it can begin increasing in temperature again. It's intuitive, but at the same time, totally insane!

[@heliomance760]

eeehhhhh... yes and no. It depends how good a thermal conductor it is, and how well it's being mixed. Artic ice caps don't prevent the sea from being warm at the equator, even though that's a connected body of water. Similarly, if you have a beaker of ice water and you heat it strongly enough, the water will start boiling before all the ice has melted, because the heat doesn't instantaneously transfer through all the water.

[@Nofxthepirate]

@@heliomance760 That's different than what I'm talking about. All the water in the ocean is in the liquid state, so it can all be different temperatures in different places. If the ocean was boiling then no part of it would be over the boiling temperature. But the ice caps would still be ice gracious that's a different state. They could melt but you wouldn't ever take a temperature reading from an ice cap that was higher than the melting point of ice. Similarly, if you had ice water and it started boiling, the water still wouldn't go over boiling temperature, and the ice wouldn't go above freezing temperature because all of the energy is going into the phase change instead of raising the temperature more.

Step 4: remove from freezer gently to avoid nucleation.

[@williamsherwood5117]

Bro just got all the myths at once🤣 Just keep it just below freezing so when it touches the ice, it brings it to that freezing point. The rest is just how it works: Since it's colder and heat travels from warmest to coldest, it releases the heat from the water into the ice, bringing the water down to a temperature that makes it change into a solid state. This is because the hydrogen bonds (a weak bond) in the water between each molecule at a liquid state aren't strong enough to hold them in the hexagonal crystalline lattice they'd like to be. When energy is removed from the electrons in the hydrogen (heat is released), the attraction from the hydrogen's nucleus and it's electron +the oxygen vs the attraction between hydrogen-hydrogen (hydrogen bond) equals out, allowing it to hold that hexagonal shape and in turn creating ice. 🧊 🙂 You might be thinking: how do two positively charged atoms attract each other? Well, a sole hydrogen atom has 1 proton, neutron and electron but wants 1 more electron to fill it's 1s orbital since the s orbital is a circle shape which needs 2 electrons to be full. If you look at the hydrogen molecule, you'll notice that it's not just a single hydrogen atom, it's H2. This is because of what I said above and that's what's happening between the two hydrogens in 2 water water molecules side-by-side. "How does the hydrogen's electron have an attraction to a hydrogen when it's already bound to the oxygen in it's water molecule?" Electrons don't live between two atoms like a Lewis diagram would show (at least in molecular bonds, ionic bonds give electrons from the cation to the anion and just sit there wishing it had them) Anyway, they share them. An orbital is called an orbital because it's an entire region that the electron can exist in. When there is as much of an attraction to the oxygen than to another hydrogen, it's going to spiral around between them as forces around it act on it.

I knew the answer to this since I was a kid. Anyone who's ever lived up north would likely have too. As a kid, there was this dammed up pond that was along my bus route to school. The dam produced a decent sized waterfall from the water spilling over the top of it. When the winters would come, the waterfall would freeze up. I remember marveling at the suspended animation of the waterfall as a kid. It was pretty cool!

[@antarbenson9328]

Yeah, the Detroit River freezes over every year. Not completely obviously, but it has a very thick ice shield.

[@cupricwheat]

Bro experienced Fimbulwinter 💀

[@jek__]

I wonder how that happens. Does the ice crystal rapidly spread through the fall, or does it start at the bottom and slowly build up as more water hits it?

[@antarbenson9328]

Water freezes at the top first, but more specifically the edges. In moving water, it starts as small chunks of frozen water that freeze faster than it melts. These chunks eventually collide with other chunks and the water between freezes and fuses. Like the rapid freezing phenomenon, the ice itself becomes the nucleation point. When a solid sheet is eventually formed it thickens from the water below. The funny thing is with the wind unable to take energy from the water to aid in evaporation the water beneath the ice shield still moves at its normal current. With waterfalls in particular its similar to icicles growing in which water runs along a frozen surface and cools enough to add a thin layer of ice around it. I assume since the warmer water is the faster it freezes due to releasing its energy at a faster pace, and with warmer water being closer to the surface, this causes it to freeze there first but that's only a hypothesis of mine and to which anyone who knows better can refute and correct me if I'm wrong.

I grew up by the river. It always used to freeze during the winter. I think it really depends on the speed of the water in motion. That river was flowing rather slowly. But at the same time, the stream, which was flowing through my garden to the said river would never freeze, as it was flowing way faster :)

[@BooBaddyBig]

The high speed thins the boundary layer. The thicker the boundary layer the more it acts as an insulator and that increases the rate of freezing. That's because it allows ice to form, and once any ice has formed, it conducts heat much better than water so a thicker boundary layer increases the speed of freezing (this is basically the opposite of what normally happens as a boundary layer slows heat flow and heat has to leave to make ice.)

[@chimmichurri6940]

seen this happen to. TBH after watching this video it makes more sens why a "waterfall" could be assumed as frozen over. Ive seen a sheer ice wall over the top of a fall, but theres still water pouriong down. Think the upper most layer like mist off the stream is the only thing able to freeze and as the fall falls, the water makes the mist thatd stick to the already made ice. im not a scientist though :B

I'm just gonna put out my thinking why flowing water doesn't freeze that easily before watching this video. So i think because in flowing water it's molecules are moving and colliding with each other so there is some thermal energy in them compared to still water (i think that's why lakes freeze easily than rivers)

[@clydeanddodo1]

Interesting I didnt know that you learn something everyday

[@jebvehxu566]

[@flametorcher7701]

I thought this was common sense in the science world lol

[@smbfelix9470]

Was my thought aswell. The river flows even in subzero, because the molecules are moving around. I guess even middleschool kids know that water freezes when the particles are to slow to move around. And you do experiments where you steer water fast and see that it's heating up.

[@deepikasharma8078]

But there are several cases in which a waterfall freezes in the air itself.

A question. Can we use this method of freezing to freeze rotatating metals and create parabolic mirrors to use them in telescope? Ofc, polish the surface if needed

I went to a school with really bad winters. When it got cold enough, we would fill up small buckets with hot water and throw it up into the air to see if it froze before hitting the ground. When it did, it always made the coolest shapes before it landed.

[@jeramiecooper1913]

I designed a water weep system for a car wash system years ago. This idea was presented, however in test, I concluded the time to freeze is a function of input / ground water temp, heat transfer rate through a tube, and time in which the water is exposed to that heat transfer rate. Another factor I didn't consider is the change the in coefficient of friction at the boundary layer when a thin film of ice forms on the ID of the tube. I haven't looked at this carwash system in years, so I don't know if that weep system is still in production.

I'm actually familiar with the first part of this. Most industrial kitchens keep their walk-in freezers at zero degrees Fahrenheit and go through a defrost cycle, usually at night, to keep the condenser working. And usually if you keep a pan under it, what you find is a column of ice forming below the condenser. And in my experience they usually look off kilter like a stack of thick disks haphazardly placed. I've always thought they looked cool. Like mesas in the desert.

That's pretty cool! Are there any fun experiments that can be done with "superheating" the water without boiling it? I think you can do that with distilled water, right? What's the highest temperature that liquid water can exist? 🤔

[@uncletiggermclaren7592]

It depends entirely on the pressure the water is at. If you put water into a container and pressurise it, the energy needed to boil it rises with the pressure. If you decrease the pressure, it boils at a lower temperature too.

[@NomadSoul76]

I don't know about water. But if you use a somewhat exotic pressurized container and liquid carbon dioxide you can end up with a very strange substance that is kind of a gas and a liquid at the same time. You go through a phase where there are some of it that's a gas and some of it that's a liquid and you can see the division but you pass through this phase and the distinction between them disappears and you end up with this stuff that's very difficult for us normal people to understand.

[@eaeaaaaa4049]

A planet does have hot ice

[@aidenaune7008]

eventually the water gets to an energy level where it is able to overcome the intermolecular forces and fly out of the main body. water reaches this point at 100 C, but due to random chaotic motion and transference of energy, water doesnt always reach this point at once. the best I think that can be done is getting all the water to boil at once.

I think also, one reason rivers are hard to freeze is that the bed/water table under the river is insulated by the water itself, so the water gets “warmed” or holds heat from underneath. I figure this is why the top of a river might freeze from exposure, but underneath the frozen layer, still flows.

Very nice experimental presentation. The way Scientific American used to be 60 years ago, as I recall. A few useful points - minus 40 degrees happens to be the same for Centigrade or Farenheit. It's where both scales cross when plotted on a graph. Also -- Water freezes at 0 C degrees, but its greatest density is at +4 C. This means the surface won't freeze if the water is mixed vertically on a large body of water. That's why you can find ice-free water around boats tied to a dock on a frozen lake. Submerged pumps beneath the boats bathe hulls with warmer, but denser, water at the bottom. There's also a safety concern with significant consequences. It happened a few years ago on a popular northern lake. The fresh water surface was very still, when a sudden cold "snap" occurred. The surface water was flash frozen before the warmer water below got a chance to sink -- passing through its greatest density (4C). while establishing a gradient density to support the ice above. Eager ice-fishing enticed people to drive on the ice because of its morning thickness. They found their vehicles drowned when ice warmed from beneath increased density and sank to the bottom -- like their vehicles. It takes time for the ice to build. Similar situations arise from hidden springs. or the water flowing beneath the ice on a river. I wonder what those fishermen would have found had they put a thermocouple on the end of a pole and lowered it gradually through a hole in the ice.

Well before watching the video, I remember once I tried to freeze bottle of water and I can't really remember if it hadn't a cap on and it just fell and freezed or if it just exploded inside the freezer and that's what made it freeze mid air, but water was frozen in a shape I assumed to be exploding water. Another thing, thanks to the not sliding property of fluids I assume it is possible to freeze moving fluids

[@paulpaulsen7777]

@@babyyoda4831 No problem. We all never stop learning. (It froze immediately, or it has frozen...) But you are right. This experiment is fascinating. Nice, your teacher showed it to you. This also can be dangerous: When you leave bottles of water outside, when it’s cold, it might happen that the water inside is still liquid. But when you open it, the pressure inside escapes and the water freezes immediately. But ice has a bigger volume than the same amount of water. So while freezing, it expands. This can make a bottle explode in your hands. Under pressure- water with gas- water can reach lower temperatures below zero. Also the emerging bubbles can then trigger the nucleation.

Jacob Osborn my understanding is that negative kelvin temperatures aren’t so much “going through 0”, so much as the inverse temperature “going through 0”, and as such, something with a negative temperature, or perhaps better thought of as a negative inverse temperature, is instead of being very cold, is instead very very hot? And is based on arranging things in a very precarious way? The temperature is related to, uh, change in heat vs, uh, change in entropy I think?
