Question: Do pens work without gravity? If not, what is a design that works in 0G?
P.S. Fun fact: astronauts don't actually eat astronaut ice cream. It was a marketing ploy.
Dear mark rober i have a question why do you only make 1 normal video per month?
Love u Mark. U are so inspirational especially to all those girls and women!
i love your work so much but here’s a question i love to ask when you were younger what was your biggest dream? was it always something to do with nasa?
Hi Mr. Rober
*pulling out a tablecloth* : "Do not try this at home!"
*pushing a bed of nails into a person using a hammer* : no such warning
I s'pose he's giving us some credit for JUDGEMENT????
Well the barrier to entry is a lot higher with the nails, both in the preparation to actually set up a bunch of nails like that and in the perception of danger associated with sharp objects and if actually done in a similar way to how it was demonstrated is actually a lot safer than the tablecloth one. I'm not saying there's no danger in the nails one but I am saying that people are much more likely to try the table cloth one and that people who would try the nails one are much more likely to understand the danger or run into issues setting it up before they get that far.
Eric D ok boomer
@@Eric_D_6 sheesh... listen to yourself. Seriously? you think we should have less precaution laying on a bed of nails than pulling a tablecloth off a table? i mean, sure, it's totally not going to result in us stabbing our butts when we sit down on nails (notice the sarcasm). pulling a tablecloth off a table is totally more safe than laying on nails (more sarcasm).
He did give us a warning ⚠️
Mark :Don't do it at home
'rethinking' wait do it at home

Rethinking*
Well now im not gonna do it

Mark, whenever your class comes on, it fills me with a sense of joy. Without school, I feel stressed about work and grades, but your teachings fill that in. Thank you so much for being an authentic, generous man, sharing your time with us to learn. I totally understand why you want to do it only on Wednesdays :)
Willie Bravo omg he likes ur comment 🤭
Thanks Mark. I don’t learn physics yet, but I Watch your videos.
Yeah
Yea I love videos its fun and also educative
I genuinely like this class because other teachers just sit there and blab about how the mitochondria is the power house of the cell but mark actually uses mental models and we actually learn stuff thats fun and exciting. Mark is literally one of the best science guys ive ever known
And kevin too (the backyard scientist)
Mark: If this hurts you fired
Alex: *Hesitates* smacks cinder block
He smashed that thing, i dont think he intended to hit it that hard when he first went to do it until mark said he might be fired😂😂😂
There was a bit of hesitation.
i felt that hesitation
I wish i can hit my teacher
i like how the last comment in the live stream is "i'll be the last one here"
How do you find them?
@@tyburrows2522 you cant. i happened to stay after the video ended to see who would be the last person (i had nothing else to do). i was going to type the ok emoji (👌) in the chat but some message said that the video was over and the live stream was 'closed'. mark rober also doesn't enable live chat after the stream.
Truly a madlad
Last time on class I think I was last maybe chat was closed for me
Lol
Questions:
How does whistling work?
Why does your stomach growl when you are hungry?
Why can you hear the water in your stomach after you have taken a drink and do some exercise?
When the gets to the small spot, all of it has to enter in such a little space at once so the ripples become closer together making it more frequent and the more the frequency, the higher the pitch
Whistling works by _ when sound is producer by air virating ur throat coords, vibrations go up in mouth and ur teeth tongue and stuff shape how it comes out. When you whistle there's a small space for it to escape makes it higher frequency. Ur stomach growls is biology due to the acid in ur stomach I think and u hear water in ur stomach cuz it's still being digested in stomach and when u move around it's being moved around aswell, crashing in walls producing sound.
Hope this helped
@@jerinjoshan687 wow so many normal sensible people
Mark: I do online classes for students
Also Mark: do not do this with YOUR WIFE’S plates
You fool I obviously have a wife at 15 I’m just that awesome
Nicholas Sanchez bro I am from Germany so my English is not that good. Is it really spelled with a V? Might change it then.
@@jesper3990 Actually it'd be "your wife's plates." No worries, English is not a simple language.
And after all your English is better than most peoples' German, mine included, so...

Make a second channel called “Mark’s Physics Class”
I would watch that.
no

yes
NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
First time In my life that I'm sad there's no more science class three times a week...

I'd love to see astronauts having a weight lifting competition on the moon.
omg this would be amazing
Keinlieb imagine they could lift the space ship
@@Kyle_v2 would be interesting to see. Definitely break all types of weight lifting records.
Keinlieb yes it would and if one couldn’t do it then the whole crew ,would you call it , could try to lift it
@Josh Drake shh, don't ruin our imagination.
It is honestly crazy how Mark knows all the answers to the questions at the end. ALL THE ANSWERS!
I never thought I would say this sentence in my life but I finally understood a physics lesson. 🤯🤯🤯 And it was actually fan to learn
Thanks mark💜
Sorry to hear your science teachers never reached you. Maybe you can find some other things that teach you cool facts about physics. You can learn cool stuff for the rest of your life.
Mark: Mass is just a measure of how much stuff is in a thing. 10:42
Me: Now that's the best description of mass that I've ever heard.
I laughed SO hard when the lady jogging with her dog stared at a grown man on the spring toy at the park
I'm so glad he's continuing with doing this understandably once a week. I'm looking forward to watching more!
Mark: "imma show u two great examples"

I love that u are doing this kind of stuff- I now look forward to Monday’s Wednesday’s and Friday’s
James Dobin-Smith just wednesdays now
Here I am at 58 years old watching your videos and reflecting on a fifth-grade trip to the Chicago Museum of Science and Industry where I was fascinated by outer space. I lament that I never had a teacher of science like you while in the K through 12 public school system that could have sparked that wonder. You, sir, will be a blessing to future students in whatever school district is wise to hire you.
Thanks so much for the science classes during this crazy time - love it x
I wish you were my physics teacher.
Megan Caron mine too
And he wishes he was your teacher
I wish josniffy was my teacher but oh well
He is mine because I don’t have physic classes at my school
He’s better than my actual science teacher.
I love that you’ve started a science class!! I am a female engineer and I have two sisters who are also engineers, we appreciate the female recognition considering how male dominated the stem fields have been in the past!!!👍❤️
Every class has gotten progressively better , excellent job jumping right it at the beginning ❤️
18:28 Mark: *wipes handle*
also Mark: *doesn't even use it.*
Your the best scientist ever.
Do more of that.

This is awesome! I can tell you're definitely getting a lot more comfortable speaking live. Also, the sets and moving parts are becoming more complex and a lot smoother with less transition time. Great job!
I'm a 20-year-old in uni and still absolutely love your school show!
I love his enthusiasm for this stuff, so inspiring

Thanks Mark, I have been homeschooling my son for a year now and love that this is an extra resource for our family.
Mark, thank you so much for this ingenious "detour", which gives our whole family something to look forward to through the week. BIG fans.
I am 16 and still watch this with joy. Dude youre awesome❤️. Keep up the great work
I'm 45, english is not even my native language, and I watch this with joy. 😎
0/10 I put "Objects are lazy" on my science test for Newton's first law and got it wrong.
Really though, great video!
Ajay Sutaria 1. Online quizzes are a thing and 2. It was a joke
I know this is a joke, but the brainiac in me wants to say “An object will not change its motion unless acted on by an unbalanced force
Thanks for what you do Mark.
My kids have been homeschooled for 2 years. My two oldest sons love your channel. Thanks for keeping the content coming, you're a go-to science resource for my kids on youtube. Thanks again
mark these classes are amazing. I am home schooling my 10 yr old. I watch these whenever they come out and I write up 4-5 questions that he has to fill out he usually has to go back and watch the video a few times. You are teaching my son science and he loves it, thank you. I never catch it live, even if you make them a little shorter and quick and dirty to make your life easier it would still be great. I understand production values and the need to make stuff look good. but usually people care less about that. I hope you keep it going.
Omg this is the only one of this science class live streams I missed, I missed this because of online school ;-;
Bad news is I didn't have a physics teacher like you in high school. Good news is, I can watch you as an adult.
Mark you are the best KRplusr there is. Thank you for doing a Science class. I am sick of not being in school. Thanks for your generosity. :)
I already love your videos, but am enjoying your classes. Thank you for doing them. As a mom to two girls, I really appreciated your comments/rant about women. Made me like you even more. Sharing in my social media and of course, with my daughters. Keep up the good work.
You are my inspiration. hopefully one day, I can understand engineering as much as you can. thanks for being my model.
Mark your literally the best science teacher ever the high school or whatever will love u you make things so clear your just so amazing thanks for doing this during this difficult time it literally gives me something to do 🥴 stay safe 🙈💦😅🥶💞
Hey Mark. You are so good at telling us things. Well done. Thanks for the info
Tomorrow's someone's birthday. Dropping a video would be a treat for us, even for the celebration..
Love you Mark. Happy birthday in advance.

Question:
Answer: "I was in charge of one chunk of the Rober" *thinks to himself: oop* "Rover".
Answer: Very carefully...
Very carefully...
With the wise words of Mark Rosewater "restrictions breed creativity" I think a topic would be better than just "do whatever you want".
Science class is awesome! I love it!
Honestly these episodes are the most wholesome and educational vids I’ve seen
Thanks for bringing that scale into space! I just lost 160 pounds up there!
Hi Mark, Could your moving dart board be switched out with a table tennis racket, so you could play table tennis against it?
Loving your new science classes! Learning something new is not always fun but learning from you has been LOTS-o-FUN lol😎 this fan thanks you for that✌
Moms full-time raising kids is more a "natural condition for thriving" than an "antiquated social norm". Love your videos BTW, keep 'em up!
GETTING HIT WITH A SLEDGEHAMMER:
MARK:
*PHYSICS!*
I was thinking “that’s very risky to do live” at the pulling the tablecloth out thing
I really enjoyed how you described Newton’s first law 😀 love all your videos ❤️ seen all the classes and haven’t missed one yet😊
I really enjoy your videos. I'm a woman in my final semester for a BS in Mechanical Engineering. Watching these videos keep me inspired and motivated to finish.
Normal physics teacher: shows class videos
Mark Rober: 9:15
isn't is suspicious that mark rober sounds a lot like mars rover?
WAIT. HE MADE A MARS ROVER. THE CURIOUSITY ROVER-
@@MrZoblox it was destiny 😲
Keep the amazing work up! I LOVE the science classes!
Your classes are amazing! Fun to follow and explanations that actually stay in mind :)
Hey dude. As a teacher, I really like the content and presentation of topics. Have you considered just not doing it live? Doing something live is alway easier when you have an audience (classroom full of students) because you can feed off their energy and ask questions and all that nervousness and anxious pauses go away. Would the editing just be too much work? Might be a good idea if you go to once a week. Cheers. Thanks for the great content.
Im watching this but i already did my science class
This is fantastic and perfect for my 8th grade science unit on Mass/Weight/Gravity! Thank you!
Awesome class and totally LOVE the music moment! I’ve watched that clip for I don’t know how many times and it is still TOUCHING! It has always been hard to be the only girl in a science and engineering club. Though there are a lot of people who had spoken about this, those words mean an extra lot when they come from one’s favorite KRplusr and idol. I really can’t appreciate more for what you are doing and thank you so much for the shout out!!! 😊
Mark: You are basically Issac Newton
Me: Holy shoot, when was I that smart??????
Hey Mark! I was wondering if u can explain why quantum mechanics and Einsteins theory of gravity don’t work other fully or at least try to explain it a little 😄
great video i never suspected they kept track of bodyweight, but as soon as you mentioned they did i figured it would have had to have been a momentum based system, really neat.
Mark, thank you for science class.. my 4 yo loves the classes and experiments/examples. and my 7 yo actually grasps your concepts!!! keep it going!
hello
mark are you thinking about making a science kit so that everyone can do their own experiments at home?
Dilan Wijegooneratne lol go to vsauce

but he should do something like that
i see what you did there!(video is at 29 minutes flat)
Your doing a super good job at live teaching! Thank you for trying to keep the kids education while this time inside! Stay safe!

Im so glad you’re going to do more of these!!!
Wouldn’t they divide there weight by 9.81 the gravitational field strength of earth and then get there mass to then multiply that with another planets gravitational field strength??
Basically yes, but a) the gravitational force isn't the exact same everywhere on earth, 9.81 is just the standard assumption and b) astronauts might be in space for extended periods of time so they want to know how their actual mass has changed.
@@Allahpaca ohh so because there weight is different up in space it effects biological functions differently resulting in losing said mass resulting in a lower weight??

I am 32 years old and love your videos. I am a higher education graduate and very proficient in maths and sciences, and still learn something new with your videos. They are highly entertaining, and also highly educational. Please keep up the great work, from at least 6ft away!
I hope you don't stop these classes. I look forward to these.
How do astronauts weigh themselves ? I guess I’ll find out
5 min in : Still waiting...
once covid 19 has ended are you going back to your old type of content?
It blows my mind how smart you are!! Love the videos!!!
Kudos and high marks for the person commenting on the previous video for posting about the Mark Rober / Mars rover audio similarity. Perfect, and perfectly apropos. Am often good at those things, but missed that one altogether. Hats off!
Mark: don't do it at home...
Me: where else can we do it other than at home (Quarantine)
Did u click the space bar when u made this video:-P
I’m so glad you’re for women in science!! My science teacher is the same as you and I adore that.
Hey man, thanks for keeping the fun and educational videos up! You're super awesome!
THANK YOU for your feminist rant :)
(And it's quite funny that it was followed by a shout out to a man :) )
Dear mark rober i have a question why do you only make 1 normal video per month?
Wow, you really know how to explain things) everything is getting so simple
Mark I love your classes! I set a reminder for the live but missed it :( but I would love to watch another one!
Hi
First comment
Actually 2nd
Kami ReVolt sorry
very very interesting how you can convey these topics. i definitely had some aha-moments during these videos. e.g. air of ocean, i didn't realize that air is basically just a fluid. and in this video my perception improved for the formula F = mg. thank you for these videos. your explanations are great! definitely go on with it!
My teacher assigned this for science class and I didn't fall asleep for once. Thank you so much Mark :)
