So we kinda like balloons? If we let the smelly air out we become heavier. Just like balloons.

Technically, "weight" is mass x gravity. When you fart, you lose some mass, ergo you weigh less. What you're actually saying here is that we become more dense when we fart, and therefore the resultant force of gravity vs buoyancy is greater in the direction of buoyancy, hence why the scales would show you as "heavier". But you're still losing weight when you fart.

My employer coerced me into teaching an evening class at a local JC. The subject was Printed Circuit Board production - drilling and routing. I dreaded the thought. Thankfully I had taken a speech class in college so I at least had a clue on how to talk to 45 people. It turned out that I actually enjoyed the "give and take" between myself and the students. It was more rewarding than I expected.

"The earth moves underneath ever so slightly" when jumping, - according to the model it moves at 15° an hour which would mean it is rotating at about 1000 miles an hour at the equator. I guess ever so slightly is subjective

adriancombe преди месец
That is totally not where I thought you were going with this, right up to the end. I was thinking in terms of how the flatulence originates, which is decomposing organic matter. Before it decomposes, it is solid. Once it becomes gas, it can leave the body. So if you compare the weight before the decomposition to the weight after, all other things being equal, you weigh less. But if you don't measure weight until after the digested food has decomposed, then of course the buoyancy is the driving principle.

This is awesome! Often my farts feel highly pressurized. Is it possible that if I packed enough fart into a small colon the density of said fart would be greater inside me than that of the air around me?

No farting does not make you weigh less, because a fart is a gas which is just stored inside your stomach so when you fart gas weighs nothing becuase its almost air but they have differences but air weighs nothing and thats onr thing gas and air have in common. So technically no farting does not make you weigh less

Man I'm still watching this video to see what he says, geez man a simple yes or no would be great. I'm assuming mathematically speaking it has to make you weight less it's less of something less of something means less you, right.

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.
Speedcuber975 преди 2 месеца
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.

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😂😂
