World's Tallest Elephant Toothpaste Volcano

When life gives you lemons... build a 5 ton flask and blast them to space.

Brody used his one wish to give a kid he never met, that had their atv stolen, a new one. What an absolute legend.

Mark’s the type of guy who buys 10 cartons of lemons in a math word problem

I love how you do things for Make A Wish kids just because and included Fletcher in on this one! The drone shots were pretty impressive too! Nurk does a fantastic job at FPV.

When Mark and Jimmy team up you know the video will be epic

AMAZING VIDEO I FREAKEN LOVE YOU

"Hey honey! What's that noise?"
"Our neighbour's making a volcano"
...
"Not again"

That volcano scene with all the spectators, I don't know why, but it reminded me of the final scene of the movie Real Genius (1985). The difference is that that laser scene had popcorn and sound from Tears For Fears, Everybody Wants to Rule the World. A big hug from Brazil to you, Mark Rober, and to all the American people!

Mark Rober is like a kid but adult and lives his dreams! I really apprecheate his fun with all his spectacular test!

"I even had child labor to do the work"
Everyone: *what?*
Mark: *What*

marks entire crew: literally spending
months in making this set
mark: 20 second build montage

You are great for creating so many meaningful things for the children and those who helped you do it.

It's great. After watching it for 2 years, I still love it. I love the way he does it. The toothpaste flies so beautifully. Like a volcano.

Imagine being able to say: yeah I met Mark Rober and broke a couple of world records, flew in a private jet, rode in a limo, went in a pool of orbies, set off a couple bombs and met mr beast in one day.

Impossible to watch a Mark Rober video without your heart being significantly warmer after

4:29 props to Mark for using his hand as a demonstration

Как бы я хотел, что бы мои дети видели и испытали хоть часть того, что испытывают дети из видео... Не в плане больниц, а развлечения. Привет из России! Спасибо за красочные и душевные видео!

The kid who used his “make a wish foundation” wish to get another kid’s stolen ATV back is so wholesome. I hope my Daughter grows up to be like that kid one day!

Ah yes, the best way to make a wooden flask stronger: METAL

Mamix: hold my beer

Mark rober will be remembered as the coolest uncle in the history of mankind.

I love how this channel has shifted to Mark becoming world's best party planner

I was smiling the whole time I was watching this it’s so nice to see you make people this happy ❤

Way to go Mark, you FINALLY did it. Also what a great mentor you are for all these kiddos.

Those drone shots are INSANE.

Just recovered you on Discovery Channel. My husband and I have enjoyed you and your science projects. Keep making us laugh and doing the weird stuff. 😂😂🎉🎉

Mark Rober... YOU ARE AN ALLSTAR...!!! The world needs a lot more of you...! Thanks, keep up your awesomeness and go enjoy some nature today...!

I honestly can't believe you're still on the quest to be the favorite uncle. I'd think you have the spot for life, Mark.

Astronauts: "Uh, Houston? We have a giant green substance here...?"
Mission Control: "Oh, yeah, that's just Mark again."

The building song montage always hits the spot👍🏼👌🏼

Mark, In Australia, we say "you're a crazy bastard" which is the highest informal compliment you can receive. I love you so much for this. You have a heart of gold and you are a wonderful person.

Mark: "we're making the world's tallest elephant toothpaste"
Me: "But don't you already have the reco-"
Mark: "Did i stutter?"

"I even have child labour to do the work"
Mark becoming a billionaire

Your videos are my favourite and I love everything that you make your the best!!!

Ordinarily I’m an “eww children” type of person, but even I can’t deny how dang wholesome Brody and Fletcher’s videos are!!

"50x the force you feel when pushing against a football" - Americans will use anything except the metric system

Imagine if Marks full time job was a party planner.

"You got me once, elephant's toothpaste! You don't get me twice!"
Spoken like a true scientist, Mark. Like a true scientist.

mark is such a kind person he has always inspirded me to be a kind person

As incredible as this whole thing was, I also wanna point out how amazing the camera work was throughout this video. I mean, the editing in all of the montages was just remarkable. Kudos to all the people behind all of that, as well.

In the end, money is just a piece of paper, this memory for this kid will be something he will remember till his final moment on earth and also for the many who participated in it!!!!
BRAVO!!!!!! You need to do more like this and change lives and with the help of many fellow tubers you can make miracles happen for the unfortunate children.
Keep up the great work!!!

This was so epic love the filming style you accomplished. Keep up great knowledge sharing.

If only everyone had an uncle like Mark, the world would be so much better

It’s almost not fair how satisfying the slo-mo in this is.

Bless those people that helped make those kids days.

This is the best craftsmanship I've ever seen.

I like how Mark's personality is basically " Yeah I try my best to be the BEST uncle, and I also do a bit of KRplus"

The toothpaste went out of frame in almost every camera shot, that has to be a testament to how it exceeded everyone's expectations even the crew's.

mark: now all we need is a 20 second building montage to finish the build
everyone who helped: *sigh* if only it was that simple

Thanks for sharing the recipe

Imagine being able to have a single wish for ANYTHING ( anything possible ) and used it for someone else. He deserved every second of that enjoyment.

Seeing Mark scared of a kid with paint on his hands makes me happy lol

Your videos are so awesome I love this one

"when life gives you lemons... build a 5 ton flask and blast them to space." These have got to be the best, most inspirational words I have ever heard.

Nobody:
Literally nobody:
Mark Rober: Spends a year designing a mega Volcano, and somehow doesn't leak any info.

Thank you so much for the chance to come out and capture this epic day with drones! Being part of the team was a dream come true!

There’s nothing more mark rover than a 20 second build montage

Just Imagine seeing that green foam tower in the distance. You dont have any context of whats going on and you just see that. Whats your first thoughts?

Hello Mark. From the bottom of our hearts, my wife and I would like to express our gratitude for bringing so much joy to our two children (Oli, 7 and Izi, 10). Thank you for sharing your time and love for science with my children. Olie definitely loves your videos.

"Sir... You want HOW MUCH hydrogen peroxyde?"
"Trust me, i'm an engineer... And that kid's very cool"

Cleaner: Anddd... the city is finally cleaned..
**The Cleaner Turns around and sees a volcano**
**The Volcano erupts**
Mark Rober: WE FINALLY DID IT!!
Cleaner: You gotta be kidding.. WHY THIS MESS!!!!!!!!!!!

bro mark is the literal G.O.A.T of youtube y`all have to agree with that!

That's some serious driving pressure. The drone couldn't even ascend fast enough. You're hired for my next birthday.

It was only a matter of time and a lot of engineering before that flask met its match. Nice one.

You are a great guy mark

THIS IS A LIFE GOAL?

More accurate: When life gives you lemons... Change a kids life.

Dude that kid was so nice and humble... literally giving his make a wish to another kid, he deserves happiness and beyond :)

This was so nice of you Mark robber🥲

Mark Rober I love your videos. I’ve been watching them since I was five and I’m 10 now please make more videos. I understand that your videos are very complicated sometimes and hard work but I really love your video so please make more

"The height of the blast was a 25-story building, which is 250ft"
2017 Kong: *Looks up in fear*

see, mark couldve made this video 5 minutes long with just the mega flask and get the same views, but instead he set up a whole fun day for a bunch of kids and made a lot of people really happy. i freaking love how compassionate he is. he always does his projects for others and not just himself. keep being you mark

I cant believe I'm your 30 millionth subscriber :) congrats on 30M

I love your Crunch Labs boxes

He always says that he is on a quest to be the favorite uncle, but who is the other uncle? What legendary hero must he overcome with insane inventions? I want answers.

It’s so wholesome when a community gets together to throw the best surprise party for a kid In need (:

THIS IS MY NEW FAVOURITE KRplusER ❤❤❤❤

Essa garotada jamais vai esquecer esse dia!

Just spent 17 minutes and 8 seconds smiling. Mark is such a great human.

As a parent, engineer and IET member I am incredibly proud that Mark has recently been made an honorary fellow of the IET. I can think of no one more deserving. Charitable, educational & inspirational. Thank you so much Mark for making engineering great again!

I love it
THANKS FOR THIS TYPE OF VIDEO ❤❤❤❤🎉🎉🎉😊

This party was heartwarming💞

Its so wholesome that everyone in town came together to help with the party.

Brody's selflessness was such a beautiful thing to see.

The manikin at 14:20 is only like "I’m still standing…🎵"

10:31 a bird XD
this video is so wholesome

meanwhile in 2030:
"So i spent the last 10 years designing a nuke out of elephant toothpaste"

Невероятно! Идея, эмоции, улыбки. Очень хорошее и доброе видео. Спасибо.
Приветствую вас из маленькой Молдовы.

Reasons why the purple elephant toothpaste pond reacts Because maybe in purple there is potassium permanganate powder mixed in it.

Pilot: Yo, what’s that green thing in the sky?
Co-Pilot: Oh it’s just Mark Rober

Mark has fulfilled his quest to become the uncle of the year, becoming uncles to many more kids than he’s related to.

all elephants in the world are like this

7:02 I KNEW IT WAS A LIMBO

If only everyone was as nice as Brody, imagine how amazing the world would be.

he's no longer satisfied with just being the favorite uncle in his family, so he has to become everyone's favorite uncle

still hope for the human kind, thanks Mark. you are a gem.

"If only all that stuff that came out of the bottom was actually forced to come out through the top"
*Dirty mind activated*

As a Brody, I gotta hand it to you for helping out the young hero Brody. He really is what a Brody should aspire to be.

For those wondering, "50 times the force when pushing against a football" is about 0,9 bar (13 psi) per ball, so in total, roughly 45 bars, or 650 psi. That's equivalent to diving to about 450 meters (1 480 feet) deep in to water.

the world needs more people like mark rober
