Acid vs Lava- Testing Liquids That Melt Everything

Most people I asked predicted the wrong winner here. Go check out the new CrunchLabs Roblox game where you can build rockets with your friends and learn stuff! www.roblox.com/BuildaRocket

I still can’t believe you can do all that to a diamond! I never would have guessed how tough they are..I’m still too scared to try it myself though 😅

William is 100% the type of person to enter a video unannounced and I legitimately couldn’t tell if he actually did until everyone else showed up

Now this is peak big kid content. Makes me feel like I'm back on the playground. Thanks for this, Mark.

Honestly some of the best content on the platform when engineer KRplusrs get together to do whatever shenanigans they feel like.

Two videos in a few days. What a treat! Thank you to Mark and to the whole entire team. I'm sure there are a lot of people who help make these happen. Happy Thanksgiving!

I've never actually seen acid at word before!
And I'm amazed nobody got hurt. None of that looked safe.
Great video 👍

Used cars for sale - slightly acidified/melted/crushed but with GREAT history.

he literally just invited all the safety third members together to destroy stuff. how fitting.

So fun fact about the anvil mark was using. Thats a common one sold by harbor freight, they do not harden their anvil's work surface like most normal anvils would have. Therefore the diamond was actually harder than the soft steel. While diamond is harder than regular soft steel it would be much more of a challenge if they tried denting a hardened steel anvil

What a line up for a video. Mark Rober is easily one of my favorite content creators. I love the editing style and music choice :)

Nigel used a weaker acid solution because he knew they'd be keeping the cars they'd destroyed at the end, truly a mad genius

Any time these guys all get together, you know it's going to be massively entertaining!

Way to go Mark! Thanks for managing our team so well!

For the ice blocks, you should have just put a single piece of pure silver on it. Silver conducts heat so well that it melts through ice like a hot knife through butter.

I knew that acid was really, really corrosive. What I wasn't expecting is how lava can be so strong and fascinating at the same time. Great video!

This episode was awesome. It kinda felt like a super nerdy and exceptionally smart version of Jacka$$. Perfect combo!

1:48 Mark’s hand wash detector is coming in handy!

I love the glitter bombs and other pranks, those are goated, but as a big fan of engineering/science YT this held a special place in my heart seeing all my favorite creators that I already watch collab together. Fantastic stuff guys.Used cars for sale - slightly acidified/melted/crushed but with GREAT history.

this episode is really starting to feel like a TV show - especially the car segment. I like it.

11:25 I don’t get why Nile didn’t choose the wood bat since wood has a buncha carbon acid would’ve eaten through it pretty easily (compared to metal at least)

Learning about science can be fun in video games. So can using things you learned and then almost forgot. For example, I learned a few things about aerodynamics and balance when I was a kid trying to become a pilot, and then I made use of it all building space planes in Kerbal Space Program. PS for the diamond, you should've used an oxyfuel torch for your wildcard. Encasing it in lava sealed it off from oxygen, but diamonds will burn. You should've hit it with an oxidizing flame.

More collabs with these guys please!! I love the energy!

Having Will, Nigel, and Kevin was great. Please continue to do stuff with them.

I love to see this genius get so excited about this stuff. Mark, you're incredibly gifted!!

Way to give yourself a HUGE advantage Mark! You're not stuck with acid or lava as your only tool of destruction, you get to tailor your method to your target.

Should have let William get in on this more. He’s the only one with the courage to commit to a task at the expense of his own health.

I am glad to see William and Alan Pan in a video again. We all need some silliness at the helm sometimes o7 may you go far Will and oh Mark Rober too

This is the kind of thing we dream about when we were kids, and Mark Rober is doing it IRL!

Thing is a flame would be more effective than lava with the diamond. But the fact that lava didn’t just burn it, since its made of carbon, still surprised me

This is straight up one of my favorite videos I’ve ever watched. It’s a crossover between a bunch of my favorite KRplusrs just doing their things.

My kids are huge fans, and they were curious who manufactured the crucibles used in this video as my husband works for a major crucible manufacturer. Thank you!

Its nice to see NileRed do what he does best. Great collab!!

Hmm, using some concepts you could probably make a self-boring acid liquid that cyclicly deposits the material around the outside of the pool and circulates

You know the video is going to be crazy when Mark decides to collab with Nilered and Kevin.

8:35 Acetone would've been much more interesting since plastic toys are made of ABS, but it's technically not an acid, so I'm guessing that's why sulfuric acid was used instead.

I thought Mark was gonna shatter the diamond at that certain angle! Drat! I was hoping he'd win that one!
I believe a diamond can break more easily if excessive force is applied at an angle perpendicular to the alignment of the atoms inside it..
Or something like that...
Overall, very fun video to watch!! Thank you!

Hey Mark when demolishing cars like in this video you should consider draining all the fluids first. Just so you’re not pouring oils, fuel and coolant into the ground

Gracias por explicar también el lado científico de las cosas:')))

For the diamond if you had used a real steel anvil it would have shattered but that's a Harbor Freight anvil and they're made of cast iron which is far too soft for pretty much anything you'd normally need an anvil for.

The fact that mark can just get his hands on Lava and acid to the amount he can cover a car is crazy

No offense to Mark, but Nigel is my guy. He is probably less than half my age but reminds of every cool science class experiment I had growing up. Watch his stuff almost daily.

Потрясающе, спасибо за 20 минут интеллектуального и инженерного удовольствия!

@MarkRober muito bom seus vídeos cada dia com novas inovações

the collaboration we never knew we needed.

I think william osman showing up despite the fact that he wasn't invited is one of the most in-character things i've seen from him

in the part with baseball bats, i would be dying from laughter when Mark would just casually pull out an industrial woodchipper

Honestly it would be cool to see Nigel, Mark, and Kevin as superheroes relating to their use of destruction in this video.

You just know he’s gonna do a science monologue when that one song comes on and I’m always excited when it does

Mark is a low-key mad scientist ngl

I'll admit, I was rooting for Nigel as I'm a huge NileRed fan, but everyone did awesome, and Kevin did the most satsifying destruction.

The Roblox world looks wonderful! I'm glad it's going to give more kids and curious minds a chance to interact with science in a fun way

Funnily enough Mark, your hammer could’ve easily broken that diamond. ActionLab broke a diamond by smashing a diamond with its point up so that’s why yours didn’t break 😁

the fact that william just showed up uninvited is so amazing and the most william thing william could do

I'm surprised you guys were just standing around with little protection when something with a lithium-based battery was getting destroyed in a glass of strong acid...

Bro I don't live in the USA, but one day I found your channel looking for something to entertain me but there really is no video that I don't enjoy, and although I'm not a kid anymore, I really admire everything you do to teach the new generations a more fun way to see science, I really admire you, you are amazing thanks for entertaining me with fun and educational science!!!!

Honestly to even the odds Nigel should have been allowed to use any non-metallic, non-high explosive chemistry he wanted.

What if you used the acid to deal with EV fires?
Like a contained payload that could put out fires in electric cars and is introduced in a way that is safe since electric fires can take anywhere from days to weeks to be put out, have the acid dissolve the sources

The collaboration on this vid is sooo incredible.

For the car, i believe what happened is the lava pierced into the injection system, and by the look its a diesel, highly flammable fuel, so of course fire extinguishers were useless, sand would've probably done it

I really appreciate your videos! My kids and I love learning from your stuff!

im happy to see William having fun hes like the mothers home cooking of create channels

Im so happy nile red has now been recognised by a larger youtuber and getting to collab with mark. A guy who likes physics vs a guy who loves chemistry

That Steamroller fail would be a perfect anticlimax villain plan flop in a Toy Story-esque movie. Like just have this dramatic terror/peril-invoking music as the mechanical monstrosity looms over the helpless toys, inching steadily closer to crushing them, and then...someone notices that it's taking an awfully long time for them to meet their doom. Cue the bunch of them looking over at it, and then suddenly end the music into silence accompanying a cut to a side angle shot of the whole thing rolling but not going anywhere because it's stuck.

13:57 who could have guessed that Mark was a pro rally driver in another life?
No but really, that looks a lot like a moment from Vilbrequin lol.

Very fun video, glad you got the Safety Third crew on.

Here for Nile Red 👏🏽👏🏽👏🏽 Love Nigel’s channel!!

What I've learned is that if you're ever in a volcano eruption, just wear armor made out of turkey legs or ice.

The addition of Will, Kevin, and Nigel was awesome. Please bring them on more often.

I'd watch a top gear episode with these four.

The excavator made me realize… Mark is just David Dobrick with common sense and empathy.

I noticed that the acid generally did better against organics and the lava did better against metals
and the wildcard was, well... a wildcard

Acid was needed in the bay round. Organic matter like wood is a way better option for acid to dissolve

This feels way less like a Mark Rober vid and more like, Safety Third goods around and I love it.

I love how mark genuinely loves to work with all these other KRplusrs without any kind of competitive attitude towards anyone and supporting everyone while doing so

After watching the ice part, I think it's safe to say that Mark is a pyromaniac (he really likes fire).

Thank you Mark for translating into Russian and other languages

He really underestimated how powerful diamonds are. I though it's common knowledge that they are very hard to break.

Maybe matpat can make a food theory on thespice level of the sauce he uses compared to lava.

Everyone has been made for some particular work, and the desire for that work has been put in every heart.

William better be in the next competition, he's literally the definition of a wildcard

Not surprised to see all these people here, William, Allen, Nigel, Kevin, and Mark are all and have been friends for years lol

I watch all 3 youtuber guys but they definitely nerfed Nigel so it could be a contest... there is no way a guy like him would choose metal over wood when he knows he is working with an acid.

These three together in one afternoon could go to Mars. They’re basically the avengers of KRplus.

I love how Kevin took off his glasses at the intro, only to have infinite glasses to look cool.

These guys are the Top Gear of Sciences

I never thought I’d need NileRed, Kevin, and Mark in one video up until now.

I’m genuinely inspired as a teacher. Thank you.

I love the contrast between the chaotic natures of william, kevin, and nilered vs the clean science video editing of mark

I love this video and marks channel in general for his personality. “I’m basically Oprah” sums it all up

Mark is slowly turning into a mad scientist. 🗿

Love the car finale and how it was pure top gear vibes perfect ending

The damage done also depends greatly on the lava you use. Silicate lava (the melted "lava rock") is generally the coolest ranging from 800C-900C. Whereas Ultramafic lava can be almost twice as hot, ranging from 1600C-2000C (hot enough to melt steel and vaporize a lot of materials).
In addition fluoroantimonic acid, Carborane acid, or Magic acid would be much more effective.

I freaking love these collabs!

Greatest scientific collaboration ever.

This felt super condensed like a diamond worth of sciene stuff stuffed into one video

Great way to show why tools that are used for heavy duty cutting are diamond tipped. 😄

As a person who watches nilered, this video was absolutely amazing

Seeing Mark Rober, NileRed, Kevin, and William in the same video is a dream come true 😁

Question about Lava : I understood this to be molten rock of some type, but I didn't hear what the lava was made of during the video.
