10kg of Red Hot Steel Vs. 15kg of Liquid Nitrogen! 

Hello beyond the press

Beyond the press, hot steel vs petrol or some sort of fuel

sam flude we will do petrol and maybe couple others on the same video

Your beyond the press videos are fantastic! HPC is good too, but these are great! you just need to advertise them more!

Beyond the press Please check out if you can make more Ice when you pour a bottle of liquid nitrogen directly into the lake!

MacDagobert Welcome to the Nelli-cuddling channel!

What about Schrödingers cat? It won, but lost at the same time...

It's in a box, so you can't cuddle it. Therefore not a good cat.

Yes, sort of. But I started earlier, about 4 winters ago ;)

Jacek R ....know the feeling!

Thin, thin, thin... fat as fuck.

cat munching

And no eye protection. Plz, Safety First

Ledenfrost effect might slow down the cooling by conduction, but that's not the main reason the steel didn't "freeze" ( it can't freeze it's already solid), the main reason is that 10kg of steel at around 500 celsius has far more energy than 15kg of liquid nitrogen can absorb before it boils. Even without ledenfrost effect the nitrogen would boil off way before the steel lost all that heat.

+Phlegm Atic I was using "freeze" there as a noun rather than a verb. I obviously know steel cant freeze, bad choice of words though. I think you are hugely downplaying the role of the Leidenfrost effect here. If you rewatch the video, from 3:05 to 5:00, the steel sits in the bath and barely changes colour, indicating that it isnt losing much heat through contact with the LN2. Then at 6:07, you can see the steel instantly change colour as its temperature drops in the water, which is much warmer than the LN2, but the movement in the water could be enough to disturb the nucleation sites, stopping the Leidenfrost effect from happening in the water. I obviously know 10kg of steel at almost 1000C has a lot more energy than 15kg of LN2 at -196C. I never said the Leidenfrost effect was the main reason the steel wasnt cooled. My observation was merely than for 15kg of LN2 to evaporate, while apparently causing insignificant cooling to the steel, that the Leidenfrost effect is significantly affecting the ability of the LN2 to conduct heat away from the steel.

+Six Beer Math Stick to maths, your physics is atrocious. The Leidenfrost effect is a process in which a liquid in contact with a mass hotter than the liquids boiling point produces a vapor layer than insulates against further heat exchange. Heat exchange goes both ways so that as 1 object heats up, the other cools down. Please elaborate on how a hot object can heat up a cooler object through thermal conduction, yet not lose any heat in the process, without any further input into the system.

Six Beer Math - Sorry bud, but when math is involved, don't exceed two beers. Error ratio excels rapidly with subsequent beers consumed.

+Six Beer Math _"The Leidenfrost keeps the liquid from boiling, not the liquid from cooling down a hot object..."_ So yes, you did say it didnt lose heat. Youre just not intelligent enough to realize you said it. _"Yes, it produces a vapor barrier, and if that barrier is taken away so that more liquid can come into contract with the heat source and that also is taken away, there is clearly thermal conduction continuing to happen..."_ Agreed. No idea why on Earth you brought this up since I didnt in any way, shape or form say it didnt. Strawman much? _What, do you think all the liquid nitrogen just went away on it's own?_ No. It boiled at its boiling point. -196C. Finland gets cold, but not that cold. _"Explain to me how there is a Leidenfrost effect when there is heat transfer from one object to the other"_ Because we dont live in a vacuum here on Earth. Obviously. The Leidenfrost effect slows down heat exchange, it doesnt stop it completely. en.wikipedia.org/wiki/Leidenfrost_effect Here you go. Educate yourself. I gave up trying to educate scientific illiterates 14 years ago.

I'm afraid there aren't any people that tall.

swiss hahahahahahahha

Wow it's so stupid!!!! I think he is dumb.

Caleb I saw it too for a second

That's just your brain recognizing known patterns. But I know exactly what you mean, I can see it too. Anyways, all cats have cat faces and this has nothing to do with Mr Weebl's cat face, but I had to think about that directly after I wrote "cat face" (and edited to become what you just read). Brains are weird. ;)

WOW ...!!!!! You are Right ...!!!!!

Your all crazy😅

Even Bellika Isaksen: Nope, not crazy. It is just like looking into the sky and trying to see some known shapes in the clouds. Crazy are people who lost their imagination. ;-)

Andy Ward thats really interesting idea. I will make it work

With white-hot tungsten and liquid helium. Orbit maybe?

Steam powered cannon.

+Tubeist-dan Orbit is not remotely possible under those circumstances. You need about 9 km/s when you subtract the losses of going through the atmosphere. You can reach 6 km/s with pre-heated hydrogen to 1300 deg C. Note, 6 km/s is faster than the average speed of the hydrogen molecules at that temperature; some of them will statistically be faster and those are the ones doing the pushing; the tube needs to be obscenely long (about a km). You have to heat the helium separately or it's not going to get very hot. Helium needs to be quite a bit hotter to get the same 6 km/s as it has about twice the atomic mass as the molecular mass of hydrogen gas (about 3100 K is needed). To reach 9 km/s with helium without any kind of rocket you'd need about 7000 Kelvin. To actually reach orbit at that speed requires significantly better heat shields than re-entry vehicles for ICBMs have on their passage through the atmosphere. Re-entry vehicles go about 5-6 km/s at the top of the atmosphere and slow to anywhere between terminal velocity and 3 km/s at sea level depending on how shallow they re-enter. Here you're demanding that the heat shield must handle 9 km/s at 1 atm. There is no room to make the projectile fatter to reduce heat loads as that will also increase friction (blunt body theory; the shockwave is pushed further out from a blunt body and heat load is much less, that's why the Apollo programme re-entry vehicles were so wide and flat, re-entering flat side first).

sgtmayhem we have couple videos about crushing really cold stuff. At least the one with locks has some nitrogen action

Hippie McFake nope but I could make one with full 20kg bottle

Do you think it would create more ice?

Hippie McFake probably bit more and I am quite sure it will look interesting from underwater

Please do it!

That would be awesome. Maybe freeze the water on contact, creating cool shapes with an underwater view...

Her name is Mili.

psygn0sis No, Nelli.

@zh84 Ahhhh, thats right. Thank you.

My cat gave herself a name. The first sound she made was "Mimi" (German pronunciation is just like two times the English word "me" in quick succession). Simple names ending in 'i' are good names for a cats, it makes it easy to call them. ;)

Once I was petting my previous cat and said to her "Who's the best cat in the world?" and she squeaked "Meeeeee!"

My favorite part hahaha

SubieLand does anything live in it lol
