I was just watching Backyard Scientist drop lava into his pool, and noted that the lava initially floated on the water for a while before it sank. My first thought was "reverse (inverse) Leidenfrost", the steam from the boiling water is keeping the molten rock afloat. And here you are now doing a video ON THAT EXACT THING!
Yeah right, my thoughts actually were like "yay, next time someone accidentally drips some water on the stove top, I can sound like I´m REALLY smart" :D

At least, with your "missed" attempt, you visualise what happens when two droplets merge (2:35), and it may help people to imagine neutron stars merging and the conservation of angular momentum.
Very well done, when I see your channel and I see the number of views , I understand , that world is so far behind, you have done a tremendous job. We collectively should promote such channels. Very well done.Thank you.
What I found interesting is that the drops form indents in the surface below so they coalesce into larger drops instead of staying independent like when the drops themselves are evaporating.
Somehow, he is able to call random strangers that he does not know for his videos. I'm surprised that he has that much charisma. (skill increased to 100)
I'm sorry, I literally forgot what the video was about the instant I saw the physicist. Also, that potential application they explained was one of the coolest things I've ever heard. It's like, Minecraft Farm mechanics in real life, except even better.
oh ... when I heard about the inverse Leidenfrost ... i was expecting floating a bubble below the surface of a fluid ... welp, I guess that would be the NEGATIVE Leidenfrost effect
moving around embryos on top of liquid nitrogen is not an application, it sucks quite frankly, YOU WANNA STORE and you'll never bother making canals of super stable and continuously replenished liquid nitrogen.
Who are the people downvoting stuff like this? This video perfectly showcases an interesting natural phenomenon and explains it thoroughly in a way that's easy to understand. Who are these descendants of amoeba who doesn't like this? I'm so perplexed.
I've observed this by accident with my coffee one morning. I dipped a biscuit in my coffee, en when some coffee dropped from the biscuit back into the mug, boom, inverse leidenfrost! That's actually what brought me to this video
Is it inverse though? I don't think the definition of Leidenfrost effect explicitly states which part should be producing the vapour. It's only us giving the example of a water droplet on a stove that has us thinking that there has to be a droplet at all. To quote Wikipedia (yeah, I know it's not the best source but still) "The Leidenfrost effect is a physical phenomenon in which a liquid, in near contact with a mass significantly hotter than the liquid's boiling point, produces an insulating vapor layer keeping that liquid from boiling rapidly." For example when a hot steel ball is dropped into water, it is Leidenfrost effect that keeps it from rapidly cooling and boiling the water.
@@niklaskoskinen123 ye it would cool faster without the vapor layer cuz then the two energy reservoirs will have nothing in between and R will naturally equal zero media.discordapp.net/attachments/424963171225436161/538472221040050207/Capture.PNG?width=400&height=73
Inverse as in; It's not the drop that is producing the vapor nor is the surface providing the heat. So Leidenfrost yes because the effect is the same but the other requirements are flipped. The steel ball in water is just a variation on scale where the hot surface is made into the ball but still the water is providing the vapor. To make it even clearer. The water droplet does eventually disappear. The hot ball does cool and the effect stops. So either the heat runs out or the water. In this setup de droplet is basically just for the ride and does not change. I may be wrong(probably am) but that is my understanding of it.
@@HenkJanBakker I get your point, that the mass ratios are recersed, but still, the definition doesn't require water nor does it require a droplet. It only requires a liquid (in this case the liquid nitrogen) and a mass hotter than the liquids boiling point (in this case the silicon oil). In no way, at least to my mind, does the example in the video differ from the definition.
I once pushed a styrofoam cup of coffee across a table and it vibrated such that the standing wave on the surface formed beads of liquid which rolled around on the surface of the coffee which was of course mind blowing. I have since repeated it a few times to demonstrate to people who don't believe me but I have never understood how exactly it works.
Speaking of potential applications, I can see it used in an RNG to generate numbers by looking at the angle in which the drop goes in reference to a fixed line and add drop wise for each request of numbers.
Very cool video. When my girlfriend next time wants me to have a hair cut, I will show her this video and say that a scientist has shown that an hair cut is not that important now compared to spending my time playing with vapor and droplets..
Спасибо вам огромное за то что делаете выпуски, но я смотрю их на отдельном канале с русским переводом, жаль что я не владею английским, но я всегда хотел бы обсуждать и вести разговор на такие темы с вами
The reason why the droplet is moving is because the vapor is not only is trying to lift the droplet, the droplet is also trying to move to the lowest level a can, but the depression that it is sitting in is also moving due to the interaction at the leading edge of the droplet with the liquid nitrogen, which is making it roll in one direction. when the trough gets all the way to the edge it can no longer be deformed and the water has a slight. splashing /bouncing causing it to ricochet off the wall which has the effect of turning the leading edge around to the other side, which then starts the process over in a new direction.
The lighting looks great on the main camera! You might want to use some colour grading on your secondary camera, the difference is pretty noticeable, which (at least to me) made it look worse in quality.

If you used oxygen for the centre beaker you'd eliminate the issue of the liquid boiling because it's got a higher boiling point than N2.

I loved the format of this video. It was great to actually bring in the scientist who did the experiment.
Is the cat required for this demo?
Would like to replicate this but I'm not sure If i need a cat
Cat is essential...
You could try but it won’t end well
You need a cat.
Full stop.
There's a 50% chance that you do.
I mean in most experiments you want to keep as many variables the same as possible. The lack of cat may have been why his first attempt went awry.
Me: Google, define "Indefinitely".
Google: Literally, tens of minutes.
"unspecified period of time" or "unlimited". He probably was referring to the former.
IcyCloud
But that doesn’t make sense either as he specifies how long right after. Not precisely, but I’d still consider it specified
@@lucaslucas191202 It's been observed for that long and then classified as indefinitely. There's no mention that it stopped after that tens of minutes, just that they stopped observing it
