The Inverse Leidenfrost Effect

Physics is awesome 😎

The human animal only sees 180° of anything around you- that you think is round or flat earth, whatever, so let’s do the math people you close your eyes you see 360° of Dark created and then you open your eyes and we created a half 180° of light everything out here and then to understand a measurement like time you must be on both sides of it Or at least 1.5 sides in order to understand the measurement. 360 we created dark, 180 WAY AFTER PERIPHERAL VISION we created light.. so if I’m born into the middle of infinity because my thoughts actually before darkness or light created —that means it’s in the future— that means it’s infinite, and that means it’s half of something you all call many different names——- in many different cultures. The BINDI is in the future people. creat-ING/2♾️

sir please do a vedio on
what is science.
how it works
why it is the best way to unravel the reality
because many people in my society doesnt understand these basics
about science and they dont belive in it. which is cuaseing many longeterm problems.

"Now you've probably heard of the Leidenfrost effect"
Sir, No

But on a hot stove there are no waves formed when you drop water so how does it really occur

Use a target-tracking laser to add heat to the oil droplet.

Reverse Leidenfrost: the Waitangiblaze effect

I don't have two Beakers but I have one Beaker and a Kermit.

What a horrible application. Think bearings for superconductor motors, or something nicer.

Dang, whoever is married to Dr. Gauthier is one lucky person!

If you made the beaker a rectangle, you could have a real-life DVD logo bouncing around!! I would unironically watch that for hours lol. 💀
Someone else might've commented this before but it was too good of an idea for me to not say.

I assume the circular shadow visible at the top of the silicone oil droplet in Derek’s trial is some type of refraction effect (or maybe reflection, but that seems less likely to me). Perhaps a topic for a future Veratasium video?

Bro be using Skype in 2019 💀

IN the bible the prophets call the firmament which divdide the waters from above the vapor canopy. I see why now.

I had a good idea this is for the free world.
The oil droplet is the spaceship and space is liquid nitrogen. Eric D W

I wouldn't now where to go from we don't know the end. I know where to start.

That my question. Thanks too veritasium I've heard my faith in science and my Maker Yhwh he is science. Amen

When i make my coffee, i sometimes make an laminar flow, when it touches the coffee it makes some lidenfroze effect but im not sure if its inverted. I think it is...

Dude, this is soooo cool

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

negative Leidenfrost effect, not inverse..

You can tell this video was from before 2020 because of the Skype call lol

Me watching this one day before my Maths paper and thinking

Hell ya , this looks amazing

I am doing similar research on Leidenfrost self-propelled droplet on ratchet.
Applications of this are …. Imagine that to make flow there should be pressure or temperature gradient.
However, using Leidenfrost we do not need pressure or temperature gradient. It will move or flow by itself.

Proud to say I wasn’t watching this at 4 am

Is this drop movement analogous to pilot wave theory?

Yeah, we all knew liednfrost effect before this

The droplet movement along the gas is because of bernoulie principle or any other thing

How about comparing with spacetime fabric 😄😋

That meet call really made me remember online classes and this was uploaded in 2019 lol

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

Freezing mouse embryos - "That's an interesting potential application of this..."

Sorry, Derek, but I have not even once in all your videos noticed your hair. Not this time, either, until you mentioned it. So, if you are spending money on it, please don't do it for my sake.

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.

It has been many years and today I find out your name is Derik and not veratasium

So they determined that the waves on the liquid are moving the droplet, but it seems like eventually they would stop propagating due to fiction/surface tension in the liquid.

Could the gradient moving the oil be caused by the droplet creating a higher rate of evaporation (due to heating the liquid more), in effect propelling the droplet in a straight line until it changes direction due to the slope of the meniscus (which makes sense). I've seen chips of sodium do this very thing on water, and it's clearly being propelled by the reaction with the water.

Well that prof isn't too difficult to look at.... no doubt I'd fail her class

What if you took a container big enough such that the rebound waves created after the introduction of the drop would be negligible, and the direction or distance of introduction is controlled, would it still move around?

Wow. You don't even need to. Droplets do this naturally. Surface tension.

Her explanation was hilariously nonchalant

Can you make the droplet remain stationary inside a dry ice bowl?

Just asking for a friend: When you advertise you listen to audio books while driving, did you keep in mind how many dumb people who already isn't paying enough attention to the road?

I'm a little confused. Why did she say a potential application is to cryofreeze rodent embryos? That's... weird. Personally I think a better potential application is to see if the math that describes that system can be used to run a search and match on the space of equations in quantum mechanics in order to discover if her equations which describe the forces of movement between various media in general, substrate-independent ways can be located in order to see if there's a kind of match for discovering anti-gravity. But, you know, to each her own.

Very well! You can also not wear gloves with LN2 for same reason.

Dr. Anaïs is beautiful 👌🏼👌🏼

Awesome video, but the name needs work.
