Hi

am I cool

I regret this comment, sorry

Ok

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 😅

How is there not a comment here

⁠@@Epicly2cause he posted it 2min ago😂😂

hi

nice comment lil bro

Your my favorite youtuber

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

"unannounced"

He doxxed his way in

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

I was gonna say the same thing, lol.

Honestly some of the best content on the platform when engineer YouTubers 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!

❤❤❤ wow your back

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.

No comment, let’s fix that!

First reply!

"slightly crushed"

ok

Hey MakersMuse you should do a video making at home retainers with 3D printer!

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 :)

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

Clearly they need to get in touch with one of the blacksmithing channels on Youtube and test that diamond against a real anvil! 🤣 Or maybe a power hammer!

AMEN@@FirefuryAmahira

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

As is expected 💪💪

Aqua Regia is one of the strongest acids in the world buddy. Its hydrochloric acid + nitric acid....Crazy strong

That sucker has a long life ahead of it too

​@@nuonchann5299aqua regia is not even close to being the strongest acid in the world "buddy".

@@nekomimicatears Which is why I said ONE of the strongest

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

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!

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.

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

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

This video will be #1 on Trending

ふ

LOL

7th wait I have a brain what am I doing?

Hi

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.

Sod off, bot.

😊

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

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

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

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)

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

This video will be #1 on Trending

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.

90% of my mind: "This is SO COOL!" 10% of my mind: "Those acids and smoke fumes aren't going to leave the atmosphere or ground water anytime soon..."

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

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

Second best collab

Nilered:science Mark rober: engineering Kevin: both

They were all on the safety third podcast too if you want to see more of them together

Yep

Yes

Mark is a low-key mad scientist ngl

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

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

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.

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 must try this. I have ice and silver

The silver would cool down fairly quickly and not have enough thermal energy to melt any more ice

no it wouldn't, that is the point. It transfers the heat from the surrounding air into the ice, which is what melts it, the temperature of the silver itself has nothing to do with why it is melting. @@No-pm4ss

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

My farts are better than Mark’s farts 💨

I’m stuff.

wulzy

@@teslacactus1135 ii love gd cologne

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

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

You need a lot of oxygen in order to burn diamond Nigel had to do it under pure oxygen for his diamond-carbonated water video

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

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

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

Nobody asked

​@@actuallyarbitrary4444ok bruh 😂

Didn't expect to see you here

Except he is screaming too much

My farts are better than Mark’s farts 💨

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!!

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.

@MarkRober muito bom seus vídeos cada dia com novas inovações

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

My farts are better than Mark’s farts 💨

So true lmao classic william

Showing up uninvited... how can you even blieve that?

honestly if it wasn't for the filming at Crunch Labs I would have guessed this was William Osman's second channel content. Surprised he didn't bring his own excavator.

@@dziubo1 we all know it was just a joke but it’s still funny

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.

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.

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.

Потрясающе, спасибо за 20 минут интеллектуального и инженерного удовольствия!

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

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

nigel is my fav science youtuber

Kevin literally risked his arrest record for science gotta love the guy

agreed

you know theyre real scientists once they get contacted by the government lmfao

Easily one of the best collabs I've seen on this channel. The Science Boys™ are a total force of chaos and watching them collaborate with Mark (and his outrageous budget per video lol) was AMAZING. More collabs with these folks, please! (Also William Osman as the "unexpected" referee was hilarious and fantastic)

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

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

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

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

My farts are better than Mark’s farts 💨

@@p-__ are you trying to poke fun at bots who post these type of comments?

​@@Heggchandwichthat a bot

Yes Nile red is cool

id argue that nile is the larger youtuber. mark is a bigger 'default front page youtuber', but nile is a titan of the actual science yt community.

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 collaboration we never knew we needed.

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.

Theoretically, would it be possible to dunk a turkey in lava and perfectly cook it?

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

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

It would have been way too easy. Acetone for the Legos. Gallium for the bat. CO₂ tablets for the car to starve the oxygen.

Power tools to disassemble it

Im pretty sure nigel could come up with something capable of dissolving pretty much everything if he can change in between rounds

@@tylerduncan5908 Galium would take too long, so he would still not win for that one.

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...

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

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!

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

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!!!!

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.

considering that his car was the only one still able to be driven back with after it was over did he really loose in the end?

@@cosmosyn2514 imagine it finally gives out in the middle of nowhere

@@thaumargaming3646 better than walking the whole distance lol

@@cosmosyn2514 well I mean he still had acid in his engine which can’t be amazing for the car

why didnt he use Pirana Solution??

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

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

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

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

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

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

Only on screen

Joined two months ago seems like someone comments it for him

​@@LinkZeeGee😂😂😂

@@LinkZeeGeedefinitely not only on screen. They’ve all had a relationship for at least a year or two.

@@chadlipscomb It's a joke my boy

The collaboration on this vid is sooo incredible.

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

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

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

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

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

The greatest dream of all time.

the science team

Yay. Willy Oz

You can’t forget Allen Pan

They are also all on a recent Safety First podcast video, discussing this video...

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

Thank you Mark for translating into Russian and other languages

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

Fun fact: Kevin got first degree burns from his lava shenanigans

ok but I wanna know what acids were used for each round, not just the last. Also, if any acidic solution is allowed, you could use piranha solution which would absolutely demolish anything organic.

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

My farts are better than Mark’s farts 💨

"For today's 'make a dessert challenge', Kevin is baking a pie with the power of refracted sunlight, Nile is chemically leavening, and using exothermic reactions to bake a cake, and I think Will is trying to... scream... a s'more into melting?" *cut to the finale of the video, the camera focused on a vacuum chamber with speakers inside* "so we didn't expect that to work as well as it did"

I'd like to see Styropyro, he is a true wildcard

He’s OP.

Not the hand wash alarm going off though lol

I think we are seeing more from the MrBeast style of videos 😊 GJ Mark! ❤

Greatest scientific collaboration ever.

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

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

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

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.

🤓

the fluoro acid is TERRIFYING!!! there is no oopses allowed. that one needs an episode all to itself.

@@DumbOrangeFrogit’s a science channel deal with it

That and he only used orange juice amounts of it, instead of the cubic yards of it found in nature. Go Team Lava!

​@@DumbOrangeFrogyou're in the comment section of a science YouTube video 🤦🏾‍♀️

Mark really tried to cheat and be unfair but it all backfired terribly on him 😂

Mark is slowly turning into a mad scientist. 🗿

These guys are the Top Gear of Sciences

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.

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

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

Mark also was on their podcast, Safety Third!

Why? They're all science YouTubers. A video like this was inevitable

Don't forget William :D

I never thought I’d see mark rober and Roblox in one video

And Roblox being mentioned too is odd af

I freaking love these collabs!

The engineer of all people thought he could smash a DIAMOND with a HAMMER. lol. Also, this missed a perfect opportunity for THERMITE! Great video as always!

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