Thanks for coming to class!! I WILL DO ONE FINAL CLASS NEXT WEEK, MAY 6TH!
@RiverTiger767 air pressure changes.
I want to see an elephant in highheels......
@The Person cool
His enthusiasm is contagious.
If all toilets flushed at once, it would not make a dent in the Swamp.
What’s under the hat? He always has one on.
if you were my teacher, I would want to stay even more in your class, this dude deserves an award
School Science Class: Boring... Mark's Science Class: Interesting!!!
the biggest crossover in history
Why are you watching this now.
You’re too adorable
Can you do an experiment or a simulation of a low pressure then it becomes a typhoon.. Iike to share it to my students for the subject environmental science and the topic is natural disaster.. And what happens when there is no plants or trees in the whole world. The question is what is the time taken to consume the oxygen and becomes carbon dioxide? Thank you sir
man i wish you were my physics teacher. Mine made us watch discovery channel each class and i literally learned nothing. Probably explained why i almost went on to almost fail engineering physics in college
So is the movie flushed away real or not real? 😂😂
you inspied me to get into enginering
Who else really wants mark to teach there science class
This was actually a question ive been wondering for a long time lol
Don’t ask why I clicked on this video....
Like its useful for people who dont understand this easily, but once u understand, its boring
Do this again plsss
Put a Democrat in before you flush.
Me After Watching This Stream: I wish Mark Rober is my new Science Teacher.
unless the elephant is potty trained, i pick the woman
So this is the science behind cutting implements. Cool.
everyone already knows that ... that's exactly what happens during Super Bowl commercials ..
This video is so underrated 2,874 comments 1,369,659 views ??? Where are all the Mark Rober fans?
Welcome to science class
Can yo do more activitys with nature like the squrell course.
I wish my teacher is like you .
Hes that one teacher that you genuinely get sad when he yells at you
The Super Bowl halftime flush
Ah yes the Moment when you jump put of a Parachute
ISchats recommends me the weirdest of all wonders.
All the sewer workers would be drowned!
I would think nothing. When watching shows like Dirty Jobs, it seemed that the sewage systems, even for large cities, was just a little "stream", if you will, of sewage flowing down a massive pipe. My guess would be that, even if every toilet in New York was flushed at the same time, the different paths sewage takes to reach the sewer would mean the load is spread over a pretty large area, and so it wouldn't just suddenly be a gushing torrent of sewage. Additionally, I would imagine sewage systems have redundancies and overflow lines to keep the system from blowing up. I remember when the giant fatberg was removed from a London sewer. Obviously that sewer line was not the only line, or else the entire community around that blockage would have backed up and wreaked havoc. But they didn't. Water might take a bit to refill, particularly in very densely populated areas, but plumbing is "primed" already (that is, my toilet tank already contains water for the next flush).
the best phy teacher
Something to think about: A blond in high heels might wreck your floors, but an elephant in the living room will destroy your entire house, because you know without a doubt, it will see a freak out and run!
Does anyone know that this actually happened in NY right after the series finally of mash. They experienced a huge loss in water pressure & a water shortage. You're welcome.
Random thought: Stars consist of tight energy force. They don't consist of pressure.
Zac king skit
The biggest question here is who did he borrow those heels from?
So when you get shot, you need to drink water and see if there are any leaks?
I can tell you what happens when all the toilets in one high school flush at once. And it wasn't pretty.
Did the elephant clean its feet before walking on the floors? I would have added food coloring to the liquid stuff so it shows up better on camera. You did a great job on this.
Mark Rober is keeping me sane tbh
I wish my teachers teached like this in school i would of learned more & not fell alseep looking at numbers in a book
When I was a kid we used to do a thing where the biggest guy in our group would lay flat on the floor & then we would position ourselves with 1 person at his head, 1 person at his feel & two people either side of him with 2 just below his shoulders & 2 people just below his butt. Then we would just use the pointer & middle fingers on both hands & lift him up off the ground. Pretty cool.
I would stay in school all week if he was the teacher!
Also, you put the tape on top of the nail/balloon thing different for the 2 than for the 12. For the 2, you put the tape all the way near the edge. For the 12, you placed it further towards the hinges. That can change the outcome of your experiment, right?
Your question was “which would you let into your house” not “which would you not let into your house”, right? I think my understanding of your solution was lost in translation.
You make me want to become smarter. My brain injury says otherwise.
if only my science class was like this.
What if the sewer got full
Oh kay! Live is never perfect. You handled it perfectly.
Why is the sanitary drain conected to the storm drain. gross af
Fakers be like OMG1!1!1!1!1 MARK ROBOR DIED
When I first watched one of your vids is when I realized I wanted to go to college for robotics
Hearing Mark's Clue 1 and asking yourself...How the heck does this involve tiolets?😂
So what about everyone taking a shower at the same time.... I feel like that happens a lot ....
I feel like im learning the same amount here or in some cases more then in school physics. You have inspired me to study science and engineering. Im from sweden so the spelling might not be right.
The thick jumper? Sweater? really helped too!
vieuwer: "what happens if you flush all toilets at the same time?" mark: "someone's gonna sledgehamer a piece of concrete on my chest while I sandwich myself between nailbeds." vieuwer: "what happens if everybody switches the light on at once?"
why is this man not my science teacher?
that bed of nails was so cool
C'mon to whom is Mark the best is telling about area of the pizza 😂
Idk what kind of red rover you are talking about but that Is not like what I know
i want mark to be my physics teacher
God Paul G. Hewitt is great.
I wish you were my teacher
Markkkk, can u be my science TEACHER?
The right equation for the examples with the water tower and the water bottle is P=h*gamma (Hydrostatic Pressure) which it depends on the height of the water surface multiply to the specific weight of the fluid.
mark you are asome
but the elephant's feet are probably dirtier!!!! :(
But the elephant only has weight on the outside edge of his foot
Does anyone actually noticed that there some small holes in his hoodie
As always Mark, great job.
Well, maybe where you live, ut where I am everyone has their own little sewer thing in the basement. When it gets full, then it goes out to the street. Not to much will happen here, though.
Who is here in the month of December 😁
that is gross it would be terible if your washer had somones waist on there clothes 🤢🤮
i FREAKING love ur science classes..greetings from Germany :)
Hmmm yes every toilet flushing in the world yes yes
The guy is cute
he is actually bleeding real bad but we cant see under his hoodie
what do u mean bleeding?!?!?!?!
How do you make lights
Your reincarnation of the classes are here!!!!!
i skipped school for this ... It was a good choice
Kyk yky tykyykyy tkt kyykykykykykyk yyktykykykykyky kwas ykktk yk tk tk jk tkt kyk yktk yyktkykykyykkyky kykkk yktkykkyy kykykkkykykykykykytkykyu
I wish he was my honors science teacher
Doesn't the funnel technically have a lower output pressure because Bernoulli's law states funnels as a high friction coefficient? :p Way out of the scope of the video, but I just wanna confirm if I recall this correctly lol
I don’t understand science when other people explain it but when mark does, it makes science more fun and easy
