Imagine Mark going to a job interview as a science teacher: "So, you were a NASA-engineer?" "Yes." "And you've been engaging and maintaining an audience with physics for years?" "Yes." "And you hold the world record in the physics experiments, such as the largest air horn and the largest elephant toothpaste experiment?" "Yes."

I believe that when you fart, you will loose weight. When you fart you release gasses including CO2, oxygen, nitrogen, hydrogen, and sometimes methane. Fart gas contains 60% nitrogen, 20% hydrogen, 10% CO2, 5-10% methane, and 5% oxygen. Normal gas that is in the air is composed of 78% nitrogen, 21% Oxygen, 0.93% argon, and traces of CO2. We can use this to our advantage by finding out the weight of fart gas compared to normal gas. We will be having 100 moles of each gas. Search up what a mole is if you don't know, because this is related to chemistry. So by doing the math, 100 moles of fart gas will be 1520 grams, and 100 moles of air will be 1468 grams. So this shows that normal air is lighter than fart gas. But you may be asking "Why are you doing all this math and chemistry? When you fart you expel gas, making you lighter!" But what I'm trying to find out through this is which gas is denser. When gas is expelled, their will be a smaller amount of molecules there. I really wish i had a diagram, but envision this. But I am going to use the example here in the video. When you have a jar of helium, if that's possible, when you open the jar, gas goes out, but the normal air around us fills it in. That's why the jar isn't just a void with nothing in it. Same thing with your farts. As you expel the fart gas, normal air will come in to fill its place. OK now this is sounding gross. And because of the calculations we did above, the fart gas is denser and is replaced by something less dense, giving it less weight in the end. And because of all of this, my answer to your question Chandler, is Farting makes you lighter

Suggestion for future lessons: when you 've given all the clues ask the chat if anyone has figured out the answer and then point out if anyone got it right. This applies to a regular classroom as well! To make sure everyone has fully understood everything ask them to explain it to you as if you didn't know anything about that topic!!!!!! Great video btw I wish you luck in your future videos and of course for your career as a high school physics teacher!!! I wouldn't mind you putting out less videos if that means achieving your dreams!!! Sorry for the long comment just wanted to say good luck too you for the future

no, i believe that when you fart, your body already took all the nutrients from your food which builds or fixes your body cells. so the fart that comes out your butt is just leftover.

When you fart you lose weight This is because when the fart is built up in your body it is actually lighter than air and it takes up the space of it so when you release that gas air is coming back in and Taking the place of that gas making you weigh more This is just my hypothesis though

I love this! I want more! However, please Mark, don't state theories to be fact when they are just that; theories. You can have an educated guess, but there is no way you can 100% prove the big bang ever happened. I'll leave you with this: The present crisis in Big Bang cosmologies began in 1986, when R. Brent Tully, of the University of Hawaii, showed that there were ribbons of superclusters of galaxies 300 million light-years long and 100 million light-years thick, stretching out about a billion light-years, and separated by voids about 300 million light-years across. These structures are much too big for the Big Bang theory to produce. At the speeds at which galaxies are supposed to be moving, it would require 80 billion years to create such a huge complex, but the age of the universe is supposed to be somewhere between 10 and 20 billion years.

Answer to Mr beasts question: Im going to use my knowledge in Chemical engineering and say that we can assume that there is a initially a greater internal pressure due to there being a gas buildup and followed by the removal of the gas where in pressure between the outside and inside of the body is equalized and using the ideal gas law(its an engineering assumption) this means that if the internal pressure decreased to match the external pressure, the moles and therefore the mass within the body decrease

Ok, so when you eat food the food goes through your digestive system where it eventually through some other processes is converted to its simpler form, they are turned into micromolecules and macromolecules. The micromolecules are generally the ones that are beneficial to your body, and those are small enough to be absorbed in the intestines where they will eventually get to all of your cells all over our body to power them. The macromolecules though are generally water and non-beneficial or toxic substances to your body so they have to be removed, they are too big to be absorbed by the intestines so they keep going trough your digestive system and to the urinary system, where they are expelled from your body in the form of urine, feces or farts. So, to sum it all up farts are essentially an initial part of the food you ate, the part that your body doesn´t need and when they leave your body you technically lose weight since mass that was part of your body, that was inside you, leaves your body, making you just a teeny tiny bit lighter. I´m a portuguese 10º grade student, so I don´t know if this is 100% factual, but it´s what I know and what I could come up with to respond the question.

Would love to see a more advanced physics video - I know it probably won't happen because a lot of your audience wouldn't understand it, but your method of explaining is incredible and it would be really cool to see that applied to a more complex topic.
