Thanks for coming to class!! I WILL DO ONE FINAL CLASS NEXT WEEK, MAY 6TH!

An amazing entertaining scientist

Mark, I'm a HUGE fan and I just want you to know that you are a role model.🙃

who else thought he said kahoot

What Does Toilets Have Anything To Do With Sleeping On Nails

OMG, I just realized this was made on my birthday!!!

you're the best guy wohooooooooooooooooo

But please if there is any space (or basement) UNDER the floor, do NOT let an elephant walk on it. Take the 110 pound lady (or Joe Exotic) and politely ask them to remove their heels.

falling asleep at 7 minutes...

A²+B²+C²=MATH

Haha, he said one FEET 2:00

I love science!

i like u u good

Imagine teacher like him Dream

why do I feel like this is an actual class zoom and he's my teacher lol? When he said that he had some announcements I thought he was gonna announce a test lol.

Ah yes welcome to school people

I love your videos

Am I the only one who knew everything he taught because in first grade my teacher taught those things

Litterly anything Mark said will be interesting if he says it.

A person is only an expert, is when they van explain a complicated concept in simple terms.

Can you come to hawaii and teach my science class?

Kk

He just made my engineering class make way more sense

If p=f/a how do they measure tensile strength. How big of an area is measured

My teacher: So bla bla bla bla bla bla bla bla My mind:*Watching a Mark Rober video* My teacher:*screaming at me for ignoring class* My mind:*still watching Mark Rober Love your vids💕

Who else would LOVE Mark being your science teacher?

Mark rober: here we answer important questions. Also mark rober: what if toilets flushed at once

yeet

If only I saw this youtube channel earlier.. this does helps my Chemistry and Physics 😭 but, it's not too late 😁

please make more

Wait, so "elephant" was the RIGHT answer? LOL! Great explanations, keeping it simple. Reminds me of a legendary story in the 1970s that some engineers synchronized the flushing of toilets in a multiple-story dorm at Rutgers College. Since we didn't have Internet back then, I'm not sure if it actually happened, or what the results were. Thanks, Mark!

20 MIL MORE TREES WITH MRBEAST

KNEWLODGE 100

9:36 is scary

This guy is like if Seth McFarlane was a scientist. I love it lol

cool

No

who's better Bil Nye or Mark Rober

I hope he does more of these

My science teacher just makes us watch this instead of her teaching

me watching all the mark rober science bc i missed my meet for science class

Do a clan with that’s amazing

The question was "What if every1 flushed blla blla blla" and i watched 25mins and i dint get the answer nice.

Alex is so handsome. Couldn't find him on twitter tho

Mark: I should lay on nails and put nails on top of me and crush a concrete block on top on a live stream what a good idea

9:21 Mark is enjoying a little something aint he?

sorry guys, i had to dislike the vid cos it was on 698 dislikes

Elephant was right , jumping outta parachute is absurd , head of water gives u a pressure of water at a height , the 6 ft head means 6 feet of water above you< 60 ft hd , more like hospital visit ?

Love this bloke! Swear he had few drinks before filming this video tho ;)

I once went to a place full of engineering. All of my daring family members (including me) Was allowed to lay on a bed of nails. From head to toe. I believe every word you say because of that. 😔👍⭐️😼

WuT

*This dude is better at explaining than all my teachers, combined*

i was never curious about this till now..

Yaaa.. I wont hear you... I will that gal in no matter what she wear

6:50 WAIT WHAT?

This is actually interesting compared to what my school does

He’s taught me more than any teacher I’ve ever had.

mark makes a good teacher ngl

9:39 mark was not an imposter...

The woman's shoes might dimple your floors, but most houses aren't built to support five tons. The elephant would smash through to the basement.

I just thought of this question today O:

If he was my teacher in high school i would’ve definitely payed attention

Woah woah woah woah woah mark rober talked about physics to his friends Me talks to my friends about interesting physics My friends - you nerd get away from us you are boring and useless you can only score in exams

Mark: the pressure is highest at the bottom. Which hole is the highest pressure? Class: middle

I wish you were my science teacher

I would kill someone to make Mark my mr.White

Stop living in the past, and get a smart board for god sake😂

90's kids be like: BILL! BILL! BILL! 2020 kids be like: MARK! MARK! MARK!

This is better than my science class lol

Mark rober's story: He was a nasa engineer. Looking good so far! He then quit nasa to become a youtuber and now wants to be a physics teacher. Why?

this was so awesome, i hope you do more!

Wait this was live!?!?!!!?

no kahoot in description tho

As a physics teacher, I love these videos and would love to use them in my classes, but the auto-captions that they currently have do not meet ADA standards for my Deaf and Hard of Hearing students. ALnets makes it pretty easy to go through and edit the captions for grammar and accuracy (ie adding punctuation and correcting any words that did not transcribe properly). I know some of your videos have full and proper captions, would love to see that for this video as well!

Are you going to be doing more of these or just your regular videos?

Please be my physics teacher

I love his example of your friends just being like hey let me do this to you, turns around and finds out they are asking you if they can stab you

Can u work in my school?... Btw I love u content. Keep it up!

24:57 Suddenly.... a physicist from Alberta makes the front page of the New York Times, with a theory disproving everything we know about pressure. Mark Rober: oh crap.

Tbh this is better than my class

1 feet on

Bottom hole

this makes me want to be a scientists

At a science museum in Baltimore there is a massive bed of nails. My school took a trip there and we all laid on it. I had no idea why it did not hurt cause we talked while they explained it but now i do. (this was minus the nails on top and the cinder block and sledge hammer)

Does anyone else ask themselves if mark has been to Area 51?

Why can’t all teachers be this passionate about what they teach

9:18 more like More like red More like re More like *Red Rober*

That title is like something from vsauce lmfao

I prefer this over my science in middle school

Mark is the balloon and Mark=popped.

Mark:"2 feet on, or 1 feet on", like if you can see the 2 mistake.

8 miniutes to tell us sharp things are sharp

I dont need sleep i need answers

Very Smart Dude but also Has His Deinterlace Method set to none wich gives off those horizontal lines and kinda makes this annoying to watch...

The answer to the boys questions at 1 am

What if channel did this already

587th

at the beginning i forgot he was talking about toilets until clue no.2

This is so much better than my normal science class
