Crazy, as part of a Camb medicine interview prep talk, one of the professors had asked this question, we initiated with friction/pressure but came to the conclusion that had to be wrong because you can’t skate on glass and water doesn’t make a difference in how skateable glass is, so we moved onto the structure of ice, and from basic principles ended up on the conclusion stated in the video, we also ended up talking about how the ‘volatility’ - for lack of a better word for the properties - of the surface water molecules allows it to slide similarly to how graphite of a pencil tip would, adding to the theory stated in the video, was fun combining more basic concepts in order to accumulate to a more difficult answer.

In university geology class, I learned that the surface state (what you called quasi-liquid) of water occurs between the nucleation (supercooling) and melting points. When ice is cooled to below its nucleation point of around -20 Celsius, the surface stops becoming slippery. I also learned the same applies to other minerals and rocks. When a rock is almost melting but not yet molten, say, at 990 degrees Celsius for a melting point of 1000, its surface also becomes slippery.

I've been obsessed with the science of ice ever since 4th or 5th grade (when I learned atoms get closer together to be solid, except water). That question on why water expands yet becomes solid haunted me until 11th grade when I took chemistry. It was so satisfying to learn that it was due to the charges on hydrogen and oxygen aligning the molecules so perfectly to create hydrogen bonds, with a ton of empty space in between from the hexagonal angles. You sir have just satisfied my other deep curiosity of water. In elementary school I had a book stating the thin layer of water theory was the cause of slipperiness, but I never fully accepted that theory as water on another flat surface did not produce the same effect. Having surface solid molecules constantly bonding and breaking due to not being enveloped by structural bonds makes much more sense.

It's because a hunk of spherical-ish space rock in a near vaccuum is about as simple as physics gets but the way the human body interacts with _all_ of the chemicals that make up food is pretty complicated _especially_ considering chemicals will also interact with each other so you have to know how the human body will interact with all chemical combinations potentially found in food and not just individual chemicals. _And_ every human body is different and each of those bodies are dynamic systems that don't stay the same. _And_ it's real easy to get into ethical issues when performing experiments on how certain foods interact with people. _And_ - do I really need to go on or can we accept that maybe life being more complicated than a large rock should be understandable?

I was explaining to one of my employees that ice is slippery because pressure causes the top layer to melt. Then part way through explaining, I realized you can easily slide light-weight flat things that exert very little pressure across ice easily. I then told my employee that this is what I've been told, but it could be wrong, or a half-truth or something, and I wasn't really sure, so take it with a grain of salt.

We should have known. At engineering school, when we were taught that water in any of its three phases do something weird (solid less dense than liquid, autoionization of water, six-side crystalline structure of ice, etc.), this is always attributed to its capability to H-bond. And indeed, H-bonding did something weird again! Thanks Joe!

Great explanation. Can you also explain how it's possible to cut ice, slowly, with a relatively low amount of force, like a weight suspended on a thread. I've heard this explained by the same pressure phase diagram argument, that doesn't really make sense due to the high pressure needed.

This makes sense. Being a delivery driver I have had my fun with ice and snow and nothing is as slippery as black ice when stepped on with a snow covered boot.

If H2S was cooled to below it’s melting point would it be slippery? The hydrogen bonds in H2S are slightly weaker

Yea he was so slippery that polnareff slipped and almost died

Properly sharpened skates have a slight concave curve between the two sides, and the skater alternates between the two edges when skating. Thus the pressure from the blade is much greater than the simplistic calculation that you used when you assumed that the entire blade width was in contact with the ice. Also only part of the blade is in contact with the ice from front-to-back, not the entire length of the blade. Even if the blade is flat, the skater still alternates between the two edges.

that fall at the beginning made my day

"we'll always be uncovering new mysteries" is the most comforting AND terrifying truth of our decade😵😂

Short: gravitation sucks Long: pressure + gravitation sucks even more

@@bemusedbandersnatch2069 I could be wrong but I’m pretty sure water is such a unique molecule due it’s hydrogen bonds being entirely unique.

This is what he was talking about at Tedx.

I let this sit in my watch later for 2 days because I thought I knew the answer already. Thanks for teaching me something!

Feynman talked about how on the surface of liquid water, there is constantly an exchange of more highly charged h20 molecules in the water with less highly charged h20 molecules in the air. When the flow is out of balance, the water evaporates.

Ah Yes, enslaved water.

Wait aren’t there astronomical objects who have ice that is formed through pressure even though its temperature is way above the melting point of water ?

I'm not scientist but perhaps the pressure is so great it forces the molecules together creating ice even at a extremely high temperature.

Water has several forms of ice, at very very high pressures you can form those ices. Look for the phase diagram of water on google.

@BainesMkII

The video has the simple Phase Diagram for water, fit for normal daily life. It gets a bit more complicated when you push it to further extremes. It is also more complicated in that there isn't just a single version of ice, but rather something like 18+ known versions (and some more that are still only theoretical?) produced at different extremes with different structures and properties.

@photonicpizza1466

That's a different kind of ice, such as ice VI, ice VII, or ice X. Different arrangements of the water molecules either to different crystal lattices, or no crystal lattice at all (amorphous ice). The ice we normally interact with, ice I, melts under higher pressure, but once the pressure gets high enough, it can reform as a solid with a different structure. Water is very, _very_ weird.

@DANGJOS

@Yasuri Kressh I'm not aware of any astronomical objects with that kind of ice, but yes, it is possible. If you extend the phase diagram to even higher pressures, the ice takes on a different structure (I think it may be cubic, instead of the familiar hexagonal ice). This cubic ice is *more dense* than not just regular ice, but also more dense than normal liquid water! So it would actually sink.

Another advantage of a VPN is that it is a proxy for all kinds of connections, while a "proxy" proxy is just for HTTP. Also, it lets you connect multiple devices to one virtual LAN network, but maybe some VPN services don't allow that.

Thanks for that JJBA reference. I enjoyed it immensely

6:06 oh dam, that reminds me of the 2016 style really much

I hate ice it cold , slippery and forms everywhere.

Note to self: Why is ice slippery? Previous theories: - There is a thing layer of water around ice Created by contact When 2 pieces of ice are placed together, they stick. The air is warmer than the ice, so there is a constant layer of water. Created by pressure Ice has a lower density than water. But... On skates 88kg human exerted on 900^2 mm only lowers the melting point by a fraction of 1 degree c. And... with normal shoes it lowers it even less. It would only work on elephants with heels. Created by friction Skating on the ice creates friction, which melts it. But it seems like you can slip even when "standing still". Water on ice is way more slippery than water on a smooth floor. New theory: - The thin slippery layer is not liquid water, or solid ice Created by quasi-liquid layer Water is a polar molecule, uses hydrogen bonding. In liquid state, there are less bonds than in solid state. On the surface of ice though, the molecule may only have 1 bond, hence "tumble around in disorder", detaching and reattaching itself to the ice and each other.. Problem: It's very hard to determine the properties of quasi-liquids, as the boarder between quasi-liquid state and solid state are very difficult to pinpoint. Where is the boarder? How to we categorise it? How thick even is it? Summary: Ice is slippery partially because of melting and fiction, mainly because of the H2Os coming loose on the ice's quasi-liquid layer.

Me at school: Im sleepy Also me at 4am: *WhY iS IcE sLipPerY?* 👁👄👁

This makes it sound like the ice cubes sticking together might be the same molecular process as cold welding polished metal plates together.
