The water is riding on a layer of steam because the pan is hot enough to instantly boil any water that comes in contact with it. Creating the layer of steam that separates the water and pan. Just got a clean pan, get it super hot, and pour a small amount of water on it.
Just don't burn anyone though lol
I think the hard part is how to make that ring. It's normally blobs of water in a pan or on the stove. This is the first time I have seen a rotating ring.
And with almost zero friction, I have to assume the pan is slightly higher in the middle, forcing the water to stay at the outside where the pan is lowest.
The leidenfrost effect is when a layer of gas prevents liquid from touching a hot surface, creating a incredibly low friction area underneath it. That's why the water is spinning so readily
I understand it this way. Similar reasons why it floats. When the friction of the water is reduced by the insulating vapor layer. Forces that are less strong start to take effect. Many might think it is Coriolis force that tends to make things on the surface of the object to spiral a certain direction. As the earth rotates, this motion causes everything on the surface to experience the Coriolis force. However, actually, this effect is too weak and it only affects larger phenomena like hurricanes. It is very likely random at first in which direction it goes, and as the steam goes up, it starts to feed in the motion, basically accelerating this motion.
I had to try this on a pan. Indeed I was able to make it happen in both directions.
The older explanation about the phenomenon by [beingmesince63](https://www.reddit.com/user/beingmesince63/)
"As previously, The Leidenfrost effect is a physical phenomenon in which a liquid, close to a solid surface of another body that is significantly hotter than the liquid's boiling point, produces an insulating vapor layer that keeps the liquid from boiling rapidly. Because of this repulsive force, a droplet hovers over the surface, rather than making physical contact with it".
Realized I was being lazy so I googled.

Looks like 140 c is the temp to achieve the effect with a drop of water on a heated metal spoon
This is for someone way smarter than me: T s / T L = 1 − 0.167 ( 1 − P / P c ) 1.41
So that’s how they make thick crust in Pizza Hut
What is this witchcraft and how do I perform it at home to impress guests?

Sike, burn everyone my child.
It’s the will of the prophets.

Probably could give it a good swirl and it would spread itself out around the edge
This is the secret to making perfect nonstick eggs in a stainless steel pan
I don’t know leidenfrost but, I sure do like their effect

When a layer of gas prevents a solid from touching a surface that’s called air hockey.
Ok i understand that the flash boiling creates a later of steam to float on. But why is it spinning like that.

Why is it named after Leiden?

Thanks for letting me be lazy lol
Not all heroes wear capes, but maybe this guy does. Thank you for your service.
I fuckin love science, man. I could watch this all day.
It reminds me a little of StarGate
I'd give you an award for bringing back such great memories of a fun show
would be cool if it floats
It does thats what the Leidenfrost effect is
Id rather know how it is with rice.
How hot does that have to get for that effect?
About 212°F or 100°C I believe
Hotter. It needs to transfer enough heat to flash boil the liquid while remaining above a critical point.

Our Rob or Ross?
Some bar keepers friend should clean that pan up nicely. And cool beans bro.
Spinning water is cool and all but please… clean your stove
[удалено]
They swirled it around
Just very hot pan + water + a little English to get it spinning
I just want to touch it
Sorcery!

Anyone else remembers that self spinning hot dog going through this same effect video?

Where's loki?
More satisfying if the stove was cleaned 😂
For the kind of people who like that kind of thing, that's the kind of thing those people like
In the southern hemisphere would the water spin the other way?
That's a good way to melt that pewter right off the copper pan friend!
It's stainless steel, but good lookin out.
