Before I watch or read anything in the comments im going to say no it doesn’t make you lighter because it’s a gas so it floats anyways so it’s not pushing down on your body - again maybe I’m wrong I’ll edit after

Precision is important and the answer to your question depends on how weight is defined. For the common definition that weight is mass times gravity, when you fart a tiny bit of mass leaves your body and you weigh less. If you define weight as the force measured by the operation of weighing it, now you have to introduce notions of support. I such cases then other forces like buoyancy can play a roll in determining the weight.

As a physics teacher, I love these videos and would love to use them in my classes, but the auto-captions that they currently have do not meet ADA standards for my Deaf and Hard of Hearing students. ALnets makes it pretty easy to go through and edit the captions for grammar and accuracy (ie adding punctuation and correcting any words that did not transcribe properly). I know some of your videos have full and proper captions, would love to see that for this video as well!

But Mark! Farts are compressed inside of you! How much would a fart have to be compressed by to be more dense than regular air?

If u were in a vacuum, it would make you weigh less. Because if you have more molecules inside of you, then it weighs more. Overall, with variables, yes, before you fart, you weigh less. But in a vacuum, if you have a baloon filled with 10 grams of helium and a different baloon (same weight of baloon) with any other gas, it would weigh more. If it was measured in the same measurement of moles, it should be the same weight.

After watching the video for 7 min, I actually thought about the question and remembered that since farting is "air" and air is bubbles and stuff which is trapped inside you, if you fart it out its like air in water which goes up, since it goes up air is less dense than water, so if that air is inside your body (which is less dense than water) and gets released, there wont be as much air therefore you are heavier albeit a little bit,

This video is a confusing mishmash of weight, mass, buoyancy, and displacement. And by ignoring compression it reached a questionable conclusion. A scuba tank certainly weighs less when empty.

@Mark Rober I don't think this is right. Why should the density of a fart in the air around you (P = 1 atm) be the same as the density of a fart inside you (P > 1 atm)? Unlike the solid objects you demoed with, gaseous objects' density should depend strongly on the pressure around them, so if a fart is, say, half as dense as air when they're at the same pressure, but the pressure in your small intestine is triple the pressure of the air around you (I have no idea what the actual number is here), farting should make you weigh less because its density will be greater than air until you let fly.
