      I stream science LIVE M-W-F at 1pm PT. Thanks for being here!

      1. Malakai Thompson

        I think the shape of the bottom is why it doesn't float - Malakai (6)

        you are welcome :

      3. Balboa Rocky

        Ok

      4. Kittenz Iwnl

      5. Shoto Todoroki

        This is random but in there wind in outer space

    2. Mullvaden83

      Im gonna go to school again just to have Mark Rober as teacher. XD

    3. 1K subbs with awesome videos

      Depends on how many farts you take out.While only 1 fart weighs 0 pounds, a lot more will weigh more, and while the farts are inside you, you weigh more.When you get them out, that weight gets out, and you weigh less.

    4. Speedcuber975

      So before even clicking on this video I had a whole thought process of “well considering that gas is trapped inside you, it should technically be helping you in the direction of being lighter the same way helium makes a balloon go up instead of weigh more. So getting rid of it technically makes you weigh more, Like a balloon loosing some of its helium wouldn’t float as high. This comment was written before watching the video at all so we’ll see if I’m right.

      I was waiting for lord watermelon to appear

    6. Carmen Yeung

      I'm 32, and I just had a WHAT?! moment, Thank you.

    7. Retro Optic

      This guy explains stuff more clearly than my Science teacher....

    8. Epic Boi

      What's making him not pop is that there is no idiots screaming in class.

    9. Duke Pfeiffer

      Make a bubble of metal it will float

    10. Ebad Rahman

      Tin foil boat Edit: ye I got it, mad

    11. Watermelon

      Awwwe mark loves playing with his dolls lol

    14. ImJustSnipeHunting

      I totally thought this was live right now.

    15. ImJustSnipeHunting

      Why do witches float?

    16. ImJustSnipeHunting

      Make a boat

    17. Isu

      i just did density like 2 days ago in my school and my teacher couldnt explain me that in 60 mins but mark explained to me in 10 mins:)

    18. Isu

      if he was my teacher i would be willing to go to school

    19. camo lion

      my farts are under so much pressure that they're denser than air

    20. Snow At sea

      I’m watching this in school on my phone for a work thing and it’s so boring

      1. Snow At sea

        I wanna go home

    21. Charles Reid

      I love that I’m not the only one who thinks about stuff like this

    22. Gummy_64

      He spent 30 minutes talking about how farts and weight are linked?

    23. BHARATH KATTIGEHALLI

      Weight is mass times gravity . Mass is like total particles in a body . I think weight not loss if we fart

    24. BHARATH KATTIGEHALLI

      Fish some have balancing organs called statocyst Remember shark don't have it so it has to swim continue

    25. BHARATH KATTIGEHALLI

      That red line is also called keel of the ship

    26. BHARATH KATTIGEHALLI

      How about increasing surface area is directly proportional to byounce force

    27. Miroslav Danilov

      Does farting makes you weigh less...is it possible somebody watched this more than s minute?

    28. Neon Reaper

      I was looking for something interesting to watch today.. And umm.... Well i guess i found something

    29. Polar9K

      Lol I hope I’m in your class

    30. Mike B

      There's a few other ways of looking at it. Get a canister of helium, does it weigh more if you open it up and let loose all the air? Answer no it doesn't, but helium weighs less than air. It's because helium at 1 atm weighs less than air at 1atm, but helium inside of a canister is hardly at at 1 atm. Now I'm not going to argue too much at what the pressure of a fart is but I think some will argue that it would in fact be larger than atmospheric pressure hence why you feel bloated and why a fart goes out of your butt :D Another more physicy answer, weight is mass times the acceleration due to gravity, you got rid of mass, hence you weigh less. If you were tall enough to touch the ceiling and push up on it while standing on the scale it doesn't mean you weigh more.

    31. Steven Chao

      flot

    32. Jack Fortunati

      What about massive dumps?

    33. Jack Fortunati

      The answer is actually C) farting makes you both lighter and heavier. In a vacuum the loss of the fart will cause you to lose mass. In a fluid less buoyant. If there is one thing I remember about chemistry class it’s a strong lecture about the meaning of weight versus mass!

    34. munsters2

      The helium balloon floats in air because the balloon takes up a lot of space, correct? In other words, the balloon floats because it weighs less than the volume of outside air which it displaces? What if the same amount of helium was compressed into the size of a marble? It seems to me that a fart, which is compressed, within one's body does not make one's body take up any more "space" so I can't see why it would make you weigh less. Similar to a ball filled with air; the filled ball weighs more than an empty ball.

    35. Garrett Brooks

      If mark does actually become a teacher I’m revoking my diploma and going back

    36. Myself

      Forgot google classroom for online learning

    37. Political Foolishness

      You take such a round-about way to answer a question. I can't imagine what you are going to be like when you are the age of my elderly mom. Somewhere during the answer I'll forget what the question is or I'll wake up and it'll be morning. 🤣 LOL

    38. The AI Powered Captioner

      By conservation of energy, energy can never be created nor destroyed. However my fart turns from gas to gas, therefore energy is conserved but tiny mass is lost😂😂

    39. pro decks !

      I’m late on this video but really curious if you where to have almost foldable wings that would retract into the object how far out would those wings have to go out to float if the scale of the object is the size of a propane bottle and weighed enough to sink?

    40. Asit Mishra

      when is persieverence launching

    41. Asit Mishra

      thanks for teaching man

    42. Richard Raghunath

      Mark would be a great teacher he makes science so fun!

    43. DSGWubsy

      Mark I'm gonna be honest, the interlacing on this video makes me nauseous

    44. DeadCorpse

      This teaches me more than zoom class

    45. J Huntley

      If it did my doggie 🐕 would be weightless

    46. Alom Xolof

      He's lost his mind 5 minutes in

    47. Death_Killer

      The similarity between Mark Rober and my chemistry teacher : Both uses a hammer to explain an example.

    48. Aamir Intisar

      I have a PHD in Physics

      What ist 1+1? Mark: When the Big Bang happened... Love ur vids btw

    54. Me

      19:50 “he was fine.. eventually.”

    55. Kristy Robinson

      You are awesome!!!!!! I have been showing your videos to my Science class for years!!!!!!!!

    56. Kelsey Baltes

      Alternative title: Mark Rober throwing a bunch of random items into a bucket of water...

    57. David Boland

      Can we get a season 2 tho

    58. Morris Music

      Does the size of the body of water you're in matter?? (I'm asking this right after the foil boat sinks... just in case this is answered later)

    59. Morris Music

      If there was a movie about Mark, Jimmy Fallon would play him..... I swear his manorisms make me think I'm watching Fallon sometimes, lol.b

    60. sue Hull

      Excellent material. Rethink those pants.

    61. shiney justin

      So by this lesson, we can conclude that there are chances to human flight if we eat a lot of beans

    62. Mohamed Abdulahi

      What about if you dripped the wood in enough water to be a density of 1 and froze it? Then tested it in water, would it float or sink? (This sounded mad horny)

    63. Enjoying Life

      Planes dont fly. They float on air.

    64. Elliot Boepple

      Yet another way that diet coke is unnatural.

    65. Elizabeth Goree

      That is so cool! I wish he was my teacher too.

    66. ZNS

      “I will link her PAprom video, go check out her channel”. It’s not there...

    67. notkirill

      Why couldn't I have a teacher like u lol

    68. Aadilah Abrahams

      Wish I found this channel sooner, still grateful for finding it.

    69. Tico buttowskii

      Now we’re asking the real questions😂

    70. Lily Hager

      When he said "tell the person next to you" it reminded me of when i was a kid teaching nobody and I talked to the class. :,) 3:50

    71. Lily Hager

      Something about watching Mark Rober teach live and uncut bc he wants to be a physics teacher is so wholesome and heart warming.

    72. Laura Alagia

      One Night in Miami

    73. Crossfire_Unltd

      I wish Mark was my science teacher in highschool lol, science was my worst subject mostly because my teachers were really judgemental, I was a straight A student until grade 11 because the teachers seemed to stop caring, and it made applying myself much more difficult when they themselves werent passionate about what they were teaching. I really hope he becomes a teacher. May the Force be with you Mark lol.

    74. HACKERISTIC 499

      Hey ! I have a question if we are in zero gravity the boency of a object is more than force of gravity will it go up ?

    75. HACKERISTIC 499

      Q : Does farting make you weigh less ? A : Yes, but actually no!

    76. Shivansh Sengar

      So theoretically a person can float just by holding in a certain amount of fart.

    77. the random funny videos of 2012

      If you use tinfoil to make the other metal float

    78. Jason Wedge

      You do great boss keep it up. :)

    79. Captain Awesome

      Finally, I’m doing something we’re other people watching actually like to learn! Science is the best!

    80. itsJeth _

      if you dont want to watch the whole thing, its yes.

    91. Bros for life

      Simple question is the answer yes or no someone plz tell me

    92. T.A. Sartain

      Imagine this guy being your high school teacher 🥴🥴🥴

    93. TheSamurai

      make a metal boat to make the metal cube float. think of it as an actual boat.

    94. Yadvesh Haritashya

      I am noob in physics and maths.please refer me books

    95. Colin Richards

      What's the difference between a chicken?... One leg is both the same?

    96. L Designs

      You are a lot smarter than my teacher trust me. I wish you were my school teacher.

    97. Maxwell Roxy

      Does farting increase inertia ▲I ?

    98. nugget 3089

      Will he still be able to do youtube

    99. Mark Kevin Sevisson

      looks like 90s video lol

    100. Conrad Tanner

      Isn't the red paint on ships antifouling paint to prevent barnacle build up???
