    2. SUBMINALAURA

      I learn more in this than i would learn in a single science lesson in class

    3. Sean Corbett

      my science teacher is sooooo boring... Mark would make things waaaayyyy better

      im bout to do my 10th grade exams i saw the first clue and knew what it was. can i just say im very proud of myself :")

    6. Daman Chawla

      this is real science

    7. Nagarjun Kashyap

      The balance between a five year old and a PhD is a five and a half year old. Change my mind.

    8. Shawn Gillen

      I’ve been an Architect for 20 years and have loved everything about science my entire life. I had NEVER had someone explain why helium makes your voice higher! I found myself smiling at that “Eureka” moment. My 16 year old son loves everything you’ve ever done and I’m glued to my screen every video as well. Keep up your enthusiasm; it’s addictive.

    9. Sean Subando

      This is the first time I listen to class

    10. Fredbear Adventures

      To all scientist If anyone has a class with mark rover Make me trade lives with them

    11. Captured with Iphone

      i have nothing to say other than, wow I LOVE U. like do more of these videos PLEASE:)

    12. Seoyool Lee

      A simple explanation: Sound, is air vibrations that your eardrums hear. Sound is slower than the speed of light, and if anything exceeds the speed of sound, it creates a sonic boom. Your vocal chords create vibrations that create air vibrations to bump into molecules. Helium makes your vocal chords easier to move, making it high pitch. Sulfur hexafluoride makes the vocal chords move slower, making it lower pitched.

    13. Arif Zamri

      hey what you're doing ! Respect the class please

    14. Charls Insigne

      I'd be lucky if my teacher in science physics is you but dang I live in ph

    15. Lynx Majic

      7:30 "There's no fluid" Flap flap 😂😂😂

    16. Fick Dich

      Why do you have to wait for a qualification? İf anything they have to check how overqualified you are

    17. Boomer Central

      Mark: through your computer or phone Me who's watching on an ipad: ;-; why to I exist

    18. Lucky 360

      I don’t think this is correct. Your vocal cords vibrate at the same frequency for all 3 gasses. The reason your voice is higher with helium is because the speed of sound is faster through that gas due to its lower density (and similar compressibility) than air. This changes the resonances of your vocal tract by making it more responsive to high-frequency sounds, so the low parts of your voice are still there, they’re just not as prevalent as the higher pitch ones with the helium. Someone please correct me if I’m wrong though, this is just what was taught to me in physics.

    19. Flavio Goetz

      i luv u mark rova

    21. adam king

      You are the Keanu Reeves of physics. My daughter loves you and your videos and for that I thank you.

    22. Prem Parekh

      Does that mean that speaking with the sulfur gas would be harder? And speaking with the helium gas would be even easier than talking normally? Someone answer lol

    23. ting durrans

      Ur the ONLY one who I would watch teaching physics 1 like = 1 person that agrees

    24. ting durrans

      I love how many times Mr . rober kept saying “we’re live”

    25. Chuck

      *pre Donald Trump* Americans: "MERICA!! YEEAH" *after Trump* Americans: 17:33 .........merica..

    26. Crantrex

      Like breathing in sulllffuuuuuuuuuuuuuur

    27. Dreanne Music

      Mark: my dream job was to be a highschool teacher Also mark: doesn't like public speaking

    28. Magnús Ari Guðmundsson

      helium is lighter than air

    29. Rumples & Things

      Ty from Dude Perfect sucked in sulfur hexafluoride for DP's 2019 tour Cool Not Cool!

    30. Michael Dombroskie

      Left the mouse on the screen when playing a video like any teacher would.

    31. Verzo Music

      Never been interested in this things, just curious BUT I love how this guy explains! I’ll be here if he drops more classes :)

    32. Eli Adest

      I love how ppl with high voices actually have stronger muscles than ppl with low voices

      1. Eli Adest

        I'll ignore the fact it's just vocal cords

    33. Si Ci

      Wait... in 10:02 he says that oil is heavier than water and it sinks. But is should not be exactly the opposite ?

    34. Epik

      I'm watching this while I'm taking science class

    35. mrwolf FN

      Pls

    36. MENTO

      I love his enthusiasm

    43. Kyle Polson

      As a Christian, it hurt to hear him say the Big Bang is real

      1. Kyle Polson

        @Arctic actually, a lot of us don’t

      2. Arctic

        christians believe the big bang is real...

      Mark, I love your classes 😊😊🎆🎆🎉🎉

    58. GM - 08JC 771132 Mountain Ash MS

      this is much better than my science 🧪 class

    59. hafsidha ak

      It is awesome

    60. hafsidha ak

      Why would 1.1 k people dislike this

    61. Scorpius Malfoy

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

    62. Subodh Thallada

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

    63. Aneeka Anwar

      Lol Mr beast and Chandler 😂😂

    64. Aneeka Anwar

      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 😊

    65. Dinesh Mehta

      @ 13:40 rip headphones users

    66. Sebastian Ortiz

      i love this channel

    67. Noah Mills

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

    68. Adam Pickard

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

    69. Dhananjay Sawant

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

    70. Phil S

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

    71. Nicholas Benson

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

    72. Shreejit Nair

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

    73. blu

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

    74. Mr.Nooblox

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

    75. CollidaCube

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

    76. SamiatheDbah

      Mark CASUAlly becoming a teacher

    77. Abhishek Kumar 9D

      Love from India you are so great

    78. Dragon Fire

      I’m in elementary school BUT WHO CARES

    79. Ferenc Sterkens

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

    80. Bò Sữa MikaZata

      you trash

    81. Sarah Smith

      you good

    82. AnglBunny

      this reminds me of Zoom (PBS Kids), thank you so much!!!

      Please never stop

    84. Mlg Dr Lion

      I want way more classes

    85. Michele Godlevski

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

    86. 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.

    87. Fishy Trolls

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

    88. Mohammad

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

    89. 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.

    90. im bored

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

    91. Cat-Man 369

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

    92. Cozy__kenna

      Pls be my teacher!!!!!!

    93. ham

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

    96. Alexander Strarup

      WAIT WHAT HAHAHAHHAHA 16:33

    97. ADITYA SRIKAR MALLADI

      If he is my science teacher I will be a topper

    98. Amairany Pardo

      Why do you reflect when you look at a mirrror?

    99. 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:).

    100. David Vargas

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