@@shaizeeshows1850 It's just used in too much for industrial scientific and educational purposes. And as dangerous as it is in direct contact, it's not like you can use it in a terrorist attack or something. A huge percentage of normal air you breath is nitrogen. It's incredibly common and remarkably inert. Nitrates(chemicals with nitrogen bound to them) are often extremely explosive, because nitrogen REALLY wants to be only bound to itself and inert. But pure nitrogen itself, even in liquid form, isn't really dangerous from a public safety perspective.

@@lukedowneslukedownes5900 i also have the same 2 questions

I second this

I thought thermal imaging was for temperature above 0°C, not really sure if it works for below 0 degrees. Edit : Okay they work below 0°C too!

@@HelloWorld-br5qg I'm not too sure with thermal imaging devices specifically, but typically with electronic devices there's a calibration element that allows you to adjust the sensitivity of the sensors. Without an element like this, the thermal imaging device would not be universally usable and you'd have to purchase different thermal imaging devices depending on what you're using it on.... which is obviously a bit stupid.

@@HelloWorld-br5qg I'm not sure if you know but 0°C is not 0 Kelvin... So even -270°C must show some heat in thermal imaging because it's not absolute 0 (0 Kelvin). Of course considering the sensitivity of the sensors and practical problems of the device.

@@karangupta4978 yeah makes sense. Even if the range of thermal camera starts at 200K, it would work really well for this experiment*.

first of all absolutely zero particles. you might also want as little air as possible dissolved inside your water

maybe it works better with distilled water

Step 1: use distilled water (no particles other than water) Step 2: let sit in the window for a day (heats up the water and causes the dissolved air to be released into the headspace [this step isn't strictly necessary] ) Step 3: place in freezer gently so as to not incorporate air back into the water. Step 4: remove from freezer gently to avoid nucleation.

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.

@@williamsherwood5117 Forestry's a way better career.

tiny vibrations are heat

@@tultrapfighter Be that as it may, the *supersonic* part denotes the use of minuscule vibrations, attempting to prevent water from freezing by vibrating and shattering the ice crystals before they can form and take hold. I personally do not believe that this would work well, as any water would theoretically dampen most vibrations. I think it would become slush.

@@stopthephilosophicalzombie9017 perfectly normal question to ask a stranger on the internet haha

@@yashagarwal8249 Answers: I live on planet Earth 😁

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.

This is a great idea!

The vapours would be an issue right

@Sid J that’s an old photo

@@MrPrkarthikeyan orr hear me out..... Time travel

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.

@@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.

just freeze something like tomato water juice and add it to the cocktail it ain’t that difficult eisteen

@@zzz_zzz_ZZZ_zzz_ZZZ_ZZZ_Z_z-ZZ You tried and failed to sound smart. Its also spelled Einstein btw "Hello, bartender? I'd like a White Russian with tomato juice ice cubes" "Won't the tomato juice ruin the cocktail?" "Well aren't you trying to be smartass, Eisteen"

Honestly I can see that being incredible and a very solid invention. If you have the will, I bet you can make a lot of money off of that idea

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.

@@multiarray2320 I know, it just needs to be very cold for a longer time

@@zorro2757 richtig

Wow, cool

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

Bro experienced Fimbulwinter 💀

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?

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 don't know why I'm so amazed by this

Yeah i know that

Yeah it is….

Yes, but did you see the picture of the guy whose canoe he was paddling was saved by the ice. At the moments of being swept over the edge the water froze, holding him in safe place at a 45 degree angle pointing down. A Army helicopter was called but the warming downdraft of the rotor blades unfroze the canoe and.... The Army were embarrassed by the avoidable death and hushed the whole thing up, obviously. I used to take a lot of LSD but I was there and saw it. The photo has gone "missing" so that proves my story and the cover up that followed.

@@aarkaarkangel I want whatever LSD your on mate

@@julius855 I would send you some but it froze solid and I destroyed it by heat by over enthusiasticly warming it up. There's a lot of "ICE" about rurally in USA, all year round too - that tweeks the brain quite effectively without fail I understand. It might take a few years to wear off though if you choose that route and your neighbours will not likely be kindly to you during that period.

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.)

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

Interesting I didnt know that you learn something everyday

I thought this was common sense in the science world lol

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.

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