      this is much better than my science 🧪 class

    11. hafsidha ak

      It is awesome

    12. hafsidha ak

      Why would 1.1 k people dislike this

    13. Scorpius Malfoy

      I'm having a science class while in math class. I'm paying attention to Mark, not my math teacher.

    14. Subodh Thallada

      I wish you were my physics teacher. I wouldn't have failed.

    15. Aneeka xoxo

      Lol Mr beast and Chandler 😂😂

    16. Aneeka xoxo

      I liked the fact I knew most of this but I didn't put 2 and 2 together (at like 35 mins was an "ohhh" moment) - I'm a gcse student, anyway thanks I also dislike public speaking 😊

      @ 13:40 rip headphones users

    18. Sebastian Ortiz

      i love this channel

    19. Noah Mills

      How do I make my voice deeper without that sulfur? Cause Im a teen and I sound like a nine your old.

    20. Adam Pickard

      The fact that I already knew this, and he still managed to engage me and blow my mind really says something

    21. Dhananjay Sawant

      Xenon and krypton(and argon) make your voice go lower(radon is toxic and radioacive)

    22. Phil S

      Please make more Mark. This is excellent for lockdown 🇬🇧

    23. Nicholas Benson

      Who feels like he needs to be a physics teacher, I’m new so I don’t know if he already is.

    24. Shreejit Nair

      Everyone's wish is to have a teacher like him🔥💯

    25. blu

      me watching physics to help me sleep: marks air horn: HRRRRRRRRRRRRRR

    26. Mr.Nooblox

      bro i wanna do science my least favorite subject besides social studies

    27. CollidaCube

      So i assume hydrogen would make it go higher, but is a little unsafe because its not a noble element...

    28. SamiatheDbah

      Mark CASUAlly becoming a teacher

    29. Abhishek Kumar 9D

      Love from India you are so great

    30. Dragon Fire

      I’m in elementary school BUT WHO CARES

    31. Ferenc Sterkens

      It would be nice if youd try to implement SI units in your explanations. Otherwise I really enjoy these classes.

    32. Bò Sữa MikaZata

      you trash

    33. Sarah Smith

      you good

    34. AnglBunny

      Please never stop

    36. Mlg Dr Lion

      I want way more classes

    37. Michele Godlevski

      OMG If I had ONLY had a Physics teacher who was this much fun...

    38. kazim hussain

      10:03 You just accidentally said the inverse of what's true, Water is heavier than Oil. Ofcourse not a big deal but you could correct it in the subtitles.

    39. Fishy Trolls

      Mark Rober talking about how he is talking while talking. Mind Blown

    40. Mohammad

      If Mark was my science teacher, I would never fall asleep

    41. Gavin Welton

      OK so the big bang never happened God created everything Mark Rober you are very smart and I feel that you should know that God created everything.

    42. im bored

      I came back to this because I got my hands on a helium ballon and almost passed out taking the whole thing :)

    43. Cat-Man 369

      Cool tip the quicker after the lightning the thunder is the closer it is

    44. Cozy__kenna

      I’m 10 and I under stand every single bit of this video

    47. Jay Junior

      @Mark Rober, can you please make a video explaining rotational kinematics 🙏🙏

    48. Alexander Strarup


    49. 星風アメHoshikaze Ame

      This is better than how my teachers teach us Edit: Mark: Air is a fluid Me: So that's why I get wet if I stay too long in front of the airconditioner


      If he is my science teacher I will be a topper

    51. Amairany Pardo

      Why do you reflect when you look at a mirrror?

    52. Mikayla Skaw

      “Teaching HS Physics is my dream job” ..... I am failing Physics right now, not because I don’t like it but because my teacher *sigh* just isn’t the best. I would absolutely just love it if you were my Physics teacher. If that could happen in some alternate universe, you would make me the happiest person ever. Your videos are the reason I’m not giving up on Physics. Seeing your videos and passion about how the world works is super inspiring and exciting:). So yes. Please become a Physics teacher. You would change so so so many students lives. Best of wishes as you pursue getting certified and all that:).

    53. David Vargas

      Ngl this is a great idea I can’t believe I wasn’t here for it live

    54. WIP

      Science was one of my weakest subjects in school, but as soon as you revealed clue 3, I had an aha! moment😃

    55. Steven Scott

    56. Deborah Ajao

      Guy who worked in NASA: Teaching high school is my dream job!

    57. b r u h

      i used to think helium was everywhere and i sucked air and talked expecting to sound high pitched but instead was normal, so then i sucked more and tried again...

    58. A.K. aq

      I'm so sad that I missed this its so cool and informative......😞💕💕💕

    59. Jesus Partida

      Hi sensei

    69. Dynamite24

      I had a choice for a bunch of assignments for my physics class, and this was one of the choices, basically, Mark Rober was my physics teacher for today.

    70. Srikar Mallajosyula

      Mark Better teach at my school.

    71. Mr Ponkan PH

      Mark said it should be at least 15 min plus 5 min for questions but then i check the time and see it 35 min mark is scamming 😐

    72. Levi Reacts

      Mark is the only one that can make me watch a 35 minute video about physics

    73. Mrbeast6000

      How are you
