This is a juicy one. 70% people get this one wrong. I stream science LIVE M-W-F 1pm PT.

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

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

  • That red line is also called keel of the ship

  • How about increasing surface area is directly proportional to byounce force

  • Does farting makes you weigh it possible somebody watched this more than s minute?

  • 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.

  • 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!

  • 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.

  • 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😂😂

  • 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?

  • 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.

  • 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 ?

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

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