        @Kevin Luo No, pens don't. Pens also don't work upside down. There is a special space pen that can be used in zero g. Watch What's Inside's vid

        I have a question Mark Rober: Ok, so if I 1v1 someone and I beat them 30-0 how much better am I then them, cause im not like 30 times, or infinitely times better because that would still be zero. Am I just “better” or is there an explanation to it?

      5. Simply Cyus

        Mark Rober I’m a HUGE FAN OF YOU when can you make some videos?

    2. lol lol

      I mostly learn things from youtube than school

      .... Um, inertia IS newton's first law. You're literally talking about the same thing. "Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia." - NASA "in·er·tia 1. a tendency to do nothing or to remain unchanged. 2. (Physics) a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force."

      I never thought I would actually see someone who worked for NASA play on a baby playground while they’re still in adult

    5. Ray Seo

      Imagine just be walking in a park and then seeing An adult playing in a playground by himself

    6. Jason Wedge

      Thank you so much.

    7. Quinn Churchill

      Ha ha we pulled off the table cloth he said by the way do you not try this at home but try this at home

    8. gangstreG123

      An educational video by a NASA-level engineer, in 2020, and we still have video interlacing. Also why does he sound like a guy about 3-4 drinks in at a party?

    9. Michelle Holmes

      I think I got it I’m on clue 2. The astronaut will stand on something that pushes them to a scale that will sense the momentum

    10. Buttifranz100 Og 1

      I wish he was my real techer😃

    11. Max Crawford

      What is it called when you lift 5 pounds 100 times instead of 500 pounds once?

    12. Michele Godlevski

      Thanks for the shout out from a female scientist. :-) Oh,and I've been having fun quizzing my engineer husband to see if he knows the answer to your questions before he sees the video.

    13. Mrbee1

      Bro I’m a boy

    14. Dmon1Unlimited

      @6:34 is that why you see some videos of big ships crashing into ports? Where the captain likely underestimated the distance needed to slow down e.g. instead of stopping at 15 miles they stopped at 10miles

    15. Yzabelle Kristín Úlfarsdóttir

      All science teachers could never

    16. Mr Ponkan PH

      im asking my self why i am watching this in the middle of our bible class i also dont know cause i dont really know

    17. TrueVexus

      I thought it was as simple as inertia and math

    18. Spinx Gregorio

      me sees a cool title watches the whole vid until u realized that the answer is just the horse at the playground

    19. Jonah Varkul

      Mark: just reflect the hammer out of the way easy. Me: sure mark.

    23. Emily Wilson

      This is fantastic and perfect for my 8th grade science unit on Mass/Weight/Gravity! Thank you!

    24. Елена Савинова

      Mark: I do online classes for students Also Mark: do not do this with YOUR WIFE’S plates


      You should try skate boarding but learning like sciencey and stuff

    26. Valdas Kulikajevas

      Mark would be the best teacher out there!

    27. Ubi Dubi DOO

      is there friction in space??? pls reply :(

    28. Sebastian Knobling

      Please do More of these

    29. Jeramie T

      Tip for ketchup bottles. Open the lid and squeeze the bottle a little and close it back up while still squeezing so that the pressure in the bottle is lower than atmospheric. And now when you open the lid after moving the ketchup to the opening, it will not spew out everywhere . Also, I sling the bottle while holding the base and use centrifugal force instead of acceleration and deceleration lol

    30. G A

      So the people who work for NASA ... that killed people .. anyhow .... now do this ... ok ))) now the space shuttle’s make sense!! ... oh not

    31. G A

      Drugs ... ?

    32. G A

      Welcome back to an adult child ...

    33. I am Asian

      thank god this si here i am having a hard time learning newtons law

    37. M N

      These are wonderful, I don't think they need to be Live to be honest! So you can take your time to make them in a way that is convenient, because these classes are excellent (I have a degree in aero engineering and I still find them engaging 😄)

    38. GG’ S

      Me quiting science to learn more from this

    39. Draw - Gon

      That ball didn't stay where it is come on mark

    40. College Stuff

      not your best work homie

    41. Christopher Krause

      Can confirm, mark rover would be an absolutely amazing physics teacher. Any school would be lucky to have him

    42. CrumblingCookie

      ''mass is what matters'' the physics dads snicker in the background

    43. uchka uchral

      5:56 my guess is by being pushed or somethins similar

    44. 5K Subscribers Without Any Video

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

    45. Name Here

      Wait so if we went to Mars I can finally be able to dunk on 10 feet?

    46. Aɭpʜʌ『Syco

      I am 13 and you teach me more than i need to know

    47. Mark Lynch

      You are good man.. Keep it up

    48. Rose Pena

      This is what we are learning now so I showed my teacher

    49. Rachel Sortino

      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. UKup 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!

    50. SBerT

      20:13 Oh my god Mark Rober Mars Rover Is it mind blowing or what? 😱

    51. Zaden

    52. Caroline Patricia

      I'm not even interested in science but I've always been following his experimental videos and istg if he's the teacher for my science class I'd understand better the way he explains things and all that

    53. Leo Etgen

      he knows me

    54. killer bee

      Please make some more

    55. MrRandom

      Imagine what that person jogging with their dog at the playground thought of Mark on the spring thing

    56. Sophie Sellers

      can you become my high school physics teacher. pls

    57. Brian Dalton

      Video idea here: DemolitionRanch on UKup has 2 videos on shooting a bullet threw a curved pipe and it works, maybe try to partner with him, honestly if your able to get ahold him he would do it any day he could. Then you give us the science on it and that video would be amazing. You could even try to partner with the slow mo guys and do clear pipes to watch the bullet travel.

    58. TheUnbidFox

      Mark makes science fun WITCHCRAFT

      I wish my physics teacher taught me like this

    61. common

      teacher who all im seeing is mark rober

    62. hermione jean

      Attach a scale to the wall and launch yourself feetfirst with an acceleration of 9.81m/s at the scale at 90 degrees to the scale? Then take a measurement of the largest force that was reached...?

    63. Willom9

      I imagined an astronaut being slammed back and fourth by ping pong rackets with a weighing scale taped to them

    65. Alex Torres

      Imagine running by a random Man riding a sea horse in the Playground lol

    66. David Ro

      Could you do a video on the theragun? I was doing some research and I believe it is a simple percussion motor and companies are up selling their massage devices when it should be less than 100 dollars.

    67. ali mir

      Make a rail gun plz

      When the only online lecture you attend is Mark Rober's.

    70. Antoinette Marlow

      OK Markie - I am a 65 yr old "girl" who loooooooooves your channel! How about that!??

    71. Maulik Mohnish

      Well you are the best today is my test this cleared my all doubt and I am from India 🤓

    72. Adam Khurshid

      I feel he should not have said that the middle east is "less progressive" womens right wise. Because in islam (main religion of middle east) women are equal to men. Just they are not supposed to be "too close" . but it is fine that you thought that

    73. Daniel Logan

      Mark: objects are lazy Machines made of objects: am I a joke to you

    74. Josiah Whitehill

      4:24 I never knew that they had tomato ketchup during Newton's time...

    75. Mannat Dawani

      The woman in the back jogging be like What is wrong with today’s generation 🤦‍♀️

    76. MSKD

      can someone please ask the caribiner to stop moving 😂

    77. Harrys Kydon

      (Guess before watching it) They use bands(out of rubber probably) that apply 1 g of force to them towards the scale?

    78. Elliotnim

      Bad astronauts get put in the astronaut shaker

    79. Catalina Zambrano


    80. person2234 I'm,a,person

      Are you reading cards.

    81. GD Bearky

      13:17 imagine what that person is thinking

    82. dirty crime boy

      Bruh I would rather be taught by mark rober than my science teacher

    83. Amaya Kadam

      Isn't ketchup a non Newtonian fluid??

      1. Bird Bird

        I personally don’t think so but it’s very likely

    84. Tiny Butterfly

      Can’t wait for new video! Hope it is good because you talking more than 1month to post hehe!

    85. Tiny Butterfly

      I would go to your class like everyday haha! Keep up the good work! Keep going!

    86. Kenny Deranleau

      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!

    87. cocsds lol

      can you prove earth is not flat?

      Easy on the drugs bro

    93. fiona corrigan

      Could buoyancy and density come up with the same results?

    94. My YouTube Channel

      Uh oh 2:20

    95. chilehead craig

      So cool seeing you talk on Science channel about the SpaceX launch 👍

    96. Aaron Buckley

      Ho else saw him on tv for the launch

    97. Scott_T

      11:15. Me. Oh! They lay in a bathtub and see how much water they displace!

      @ 12 mins, I made this guess: A spring stimulates 1g mounted to the floor . Another spring scale (like a big fish scale) attached to the the spring and to the roof, set to 0. As we apply downwards pressure (between the floor spring and the roof spring). The spring scale should note the change of the 1g spring + the applied pressure" ... back to video to see if I am correct.

      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!
