I have a VERY serious question! Can Sup Forums help me?
Say someone was going to BEAT your ass. Like literally pull down your pants and punch you DIRECTLY in the asshole. >How HArd would you have to fart to stop an average 25MPH punch?? >Like stop the fist dead in it's track.
I know it's not a physically possible fart, but what if it was?
>Would It do more harm than the fist ever could? >Maybe it would bruise your entire lower intestine >Maybe it would rip all the flesh off your pelvis
I don't know and I need to!
Maybe someone with one of those asshole sex dolls and an air compressor could answer my question for me?
Please, it takes a physicist could solve this question, but only a retard like me could come up with it.
You got a bug up your bum? Gonna ram my fist up your ass and get that bug.

Equal or higher force to stop inertia of a punch
> or >/= 25 mph will stop the punch
Would definitely cause your body harm
Mason James
C'mon I know one of you maniacs has a butthole sex toy and an M80. Do it for science
Henry Reyes
I'm no physicist OP but given the major difference in density of both objects you're gonna need at least two things : A stupidly powerful sphincter to reduce the stream size of your fart as much as possible AND an even more powerful set of intestinal muscles to produce enough pressure to push that through your backdoor
Parker Cook
Guys, EVERYONE, PLEASE DO NOT PLAY WITH COMPRESSED AIR. There have been plenty of deaths associated with these pranks, googel it
David Sanders
Define hard, like PSI? Also, how are we gonna compress all that into a human intestinal tract/rectim. What kind of person could hold all that in or even consume enough food/beverage or smoke enough cigarettes to get it in there? The size of the rectal cavity also needs to be considered. Tighter assholes are obviously preferable, but how tight can we feasibly get?
You have to know the area of the fist, the density of the fart, and how much inertia is in the punch. Then you find out how much PSI you would need to match the inertia of the fist. You would have to move a metric fuck ton of air very fast in order to cancel the fists momentum. Absolutely not way in hell you'd be able to do it. Think about an average air compressor letting out air at 120ish psi. That doesn't come anywhere near stopping your hand when its flat and barely moving
I'm an engineer by the way. Not going to do the calculations, its actually a pretty simple calculation if you have all the info you need. Air has weight, so just imagine you need the same amount of weight in air as you have in the first, moving at the same speed as the fist
Brayden Flores
Fist in the last sentence. Fuck I'm autistic and can't type
You air weight has to equal your fist weight, and the fist-weight volume of air has to be moving at 25 mph. Or you have to have a smaller volume moving much faster. Your equation would be a function of air volume and air speed.
Jayden Davis
Honestly given all the variables it would probably just be best to do an actual physics simulation in Houdini or some other program. Just make an ass mesh with a rectal cavity of the general average. Turn the mesh into a volume of the same density as flesh, support the whole thing with a pelvis mesh, you can probably find one on turbosquid. Put an air compression force emmiter inside. Then just propel a fist at it and adjust the force till it stops
PS if anyone makes a video of this sim I'd like to see it. Lmao
Oliver Wood
op, you have sufficiently captured my attention. i had no clue i wanted to know this, but i do. somebody plz
say the punch is 1200 psi, then 1200 psi fart. Now this is a simple answer but if your normal farts were 1200 psi, your pants would be catastrophically destroyed
Isaiah Peterson
Average gas volume of a human fart=0.66 liters Average volume of a human being = 71 liters
71/0.66= ~107.5 times of speed beyond speed of equivalent gust of wind to match a regular gust of wind
Gust of wind powerful enough to blow you over and away, stopping your punch = 200 mph
200 mph gust of wind * 107.5 wind to fart ratio =21500 mph fart, or about Mach 28
Chase Baker
Well, the more gas that passes through the orifice, the wider it's going to become, and the weaker the stream.
If we compare it to something like a power washer (which will not stop a punch) you're going to need enough anal pressure to pretty much fire your asshole at your opponents fist, with little chance of recovering your peach ring.
Liam Hernandez
Please, my bully says tommorow he is going to punch my asshole again. Last time I farted on his hand he called me a faggot and said I got shit on his knuckle, then he beat me harder. How do I achieve the Hiroshima fart?
Aim higher than hiroshima my guy, you’re going to need a Super Sayian Fart
Elijah Allen
"A study of 12 karate black belts showed so-called reverse punches delivered an average force of 325 pounds, with the strongest measuring 412 pounds."
So you'd need to fart with a force of 325 pounds to stop the punch of an average blackbelt.
Logan Jones
fucking mach 28 straight out the asshole?! i wonder if you could rip the fabric of space and time and create a worm hole that way. like fart so hard the attacker turns to dust then like implodes sucking the world we know into your asshole
is there any kind of way to strengthen your asshole beyond what science thought was possible? like have an asshole power of over 9000 and completely disintegrate their hand?
Elijah Hall
kek, just like swan dive into an asshole from 2 stories up
Gavin Anderson
The force would expel your entire lower intestine from your body all over the puncher. It would be the worlds ultimate prolapse. Granted your attacker would be sufficiently deterred. So that's kind of a win. It's basically what sea cucumbers do
if you could fart that hard then shove a deth spike or a bullet into your asshole and just kill the dude. or like hide in the bushes and ass sniper that mother fucker
Lincoln Sanchez
Nice question. I am a physicist and I could probably give a fairly good numerical estimate based on simple assumptions and average parameters. Thing is, it's 5am and I'm not getting up this early but will make the following comments:
Things to consider: - Area of front face of fist - Mass of fist/arm/shoulder assembly - Diameter of fully extended asshole - Fart density
You can get your answer with this information and a few equations.
As for how damaging it would be: - Assholes aren't that strong and can tear so you'd probably shred it pretty badly - The amount of fart gas you'd have to store in your ass would mean you'd either be bloated to the point of ripping to pieces long before you got to that point; or it would be at such high pressure you'd explode
Connor Morgan
Most tissues, ligaments, and bones in the body become stronger with extreme use and mild abuse. Considering that your sphincter is a collection of muscles, you could probably strengthen your asshole with some unholy method, but it may come at the cost of a loose butthole (scar tissue), which is effectively your pressure switch. So, potentially, a stronger butthole may actually make for a weaker stream.
The answer may lie in your pelvic muscles. If you make your abdomen strong enough, you may be able to force out more air at the cost of your balloon knot.
Again we're talking about gale force winds coming out of your ass
Levi Barnes
>this post >that fucking picture OP you created solid gold with almost zero effort.
now THIS is the kind of content that Sup Forums should have.
Aiden Rogers
If done in that position the fart would most likely push the person forward and break the sound barrier so you would go at mach 1 speeds to stop a punch while also imploding your insides -physics fag
Not an expert, if the pressure ever builds too much in your bowels they naturally release as a fart, your ability to control this has little do with sheilding but with actually trying your asshole to not relax when recieving the nervous signals. The bowels in of themselves are able to hold a substantial amount of pressure dispite their softish chemistry, but the amount needed to reduced the movement of an rigid body form already in free space from atmospheric pressure would be that of 400-500 psi. Much more than any human organ could muster, we naturally are subjugated to a single atm amount of pressure to begin with but you would need to withstand over 90 atm.
Jack Richardson
Assuming the whole intestine and rectum isnt thorn to shreds, wouldnt all that wind create enough of a drag to pretty much shoot your intestines out like a prolapse world record? Im still iffy about that Mach 28 result, but it would still be fucking lot of force in that gas ejection. And every force has an equal and opposite reaction, that would mean whatever outlandish result we find hitting you back onto your already destroyed asshole
Sebastian Rodriguez
This is unrelated but: could you kill someone by prolapsing their anus?
Josiah Foster
Are you ripping their ass out or are you shooting your prolapse anus at them like battering ram with enough force to break their head in?
Brayden Harris
Fuck off liberal bernie supporter
Angel Sullivan

Luke Harris
WE need numbers for the math! I don't know the averages of everything so we can just use some basic measurements I took from myself:
Front of Fist area: 8.75" Mass of fist/arm/shoulder assembly: One sec gotta weigh myself before and after removing my arm. Diameter of fully extended asshole: 8" Fart density: A mouthful tASTE: Delicious
Leo Torres
lel
Juan Mitchell
so like you could use it as your final move? like a self destruct gust?
Leo Reyes
I was gonna say I'm ripping theirs out but the latter sounds more interesting. What's the force your prolapsed anus would require to fracture a human hand?
Henry Allen
This is at least a step closer to solving this problem. Thanks for providing the info that the taste of the given ass blast is deemed Y U M Y U M Y U M D E L I C I O S O
Are you retarded? It's a 2D slice so it's not 3 anuses (or anii as we say in science) it's the inner and outer rectums (or recti, as we say in science)
Where did the physicist go? I know he said it was late, but how could he possibly sleep with a question like this rattling around in his head? I'm sure in a couple hours he'll wake up in a cold sweat and rush to his computer to solve this conundrum.
Cameron Lopez

Jaxson Perry
>Im still iffy about that Mach 28 result,
I think it's too low.
My estimations were much simpler. Mass of human hand + forearm + some of upper arm ≈ 2.5 kg 25 mph = 11.8 m / s Momentum of "fist" ≈ 30 kg m / s
Mass of gas expelled by fart ≈ 1 g (based on a 1 L fart and a gas density under standard condtions of about 1 kg / cubic metre. Other user reports farts are less than 1 L. Air density is closer to about 1.2 kg / cubic metre, so 1 g is very reasonable).
Hence velocity has to be ≈ 30 km / s which is around Mach 90. The US Navy's Hyper Veloicty Projectile travels around 9 km / s or around Mach 27.
The basic maths is very simple: Mass of "fist" is 2500 times mass of gas therefore Velocity of gas is 2500 times velocity of "fist"
This assumes all the momentum of the gas goes into retarding the fist, which it won't.
The gas itself has a kinetic energy of 435 kJ or 218 times the muzzle energy of a typical AK-47 round.
This is a conservative estimate.
Jacob Mitchell
Yeah, figuring in the total kinetic energy of a punch, and removing the kinetic energy lost through tissues and joints during impact, then weighing that against an airstream is an extreme mathematic undertaking.
Easton Mitchell
Hmm, so it would be much more efficient to just fire a turd nugget with the compressed fart to stop the fist.
Noah Myers
Or If you waited til the exact moment the fist made contact in order to form a seal between your rectum and the face of their fist
Christian Harris
>Mach 90 >This assumes all the momentum of the gas goes into retarding the fist, which it won't.
So our results for a fist retarding fart should be above Mach 90 to make up for the lost momentum?
Logan Johnson
Yes. Though we can't be sure of the parameters of your asshole, you would be better off firing a D-battery out of your ass at your would-be-attacker.
Since the walls of your ass are elastic, the pressure within won't stop a fist, we have to rely purely on air force, so unless you can manage a mach-90 microburst like the other user said projectiles are the answer.
Jason Walker
so hard you'd damage your bowels more than if you had just taken the fist.
A simple test is to stick your fist out the window of your car and see what speed your car goes when your fist gets pushed backwards. Then stick your asshole out the window of your car and see what speed your asshole gets blowed up. Once you have gathered that data then all you have to do is plug the numbers into your fart strength calculations.
Cooper Perez
Fucking kek
Julian Nelson
In essence yes, but there's no conervation of mass possible in this problem unless there's a magic fist or Marvel-style adamantium involved.
The kinetic energy 218 Ak-47 rounds acting on an around 0.8 sq cm area of hand (assuming gas emitted from a 1 cm diameter orifice and retains that cross sectional area) is going to remove mass from the arm by turning it a fine red rest or more likely a plasma given the speed at which this takes place.
There will be a lovely hole punched right through the arm, entering the fist and emerging at the elbow if not sooner, and then there won't be any area for the gas to act upon.
Carter Sullivan
This thread appeals to my inner scholar and my inner autist. This truly is what Sup Forums was made for
Camden Green
>fine red rest *fine red mist
Henry Sanchez
I can stick my fist out straight during top speed on a roller coaster and those go way faster lol
Isaiah Miller
Probably closer to mach 200, especially since most of the fart will be pushed around the outside of the fist. Kind of like the aerodynamics of a car.
Jackson Flores
All this is assuming the fist is invincible. What would it take to just disintegrate the fist? Way less than Mach 28 I bet
Jack Diaz
Icba at this time!
Resolve your forces! Exit fart gas is like Aviation thrust so find Newton's per square inch.
Also it's not just the fart but the exit arc and concentration -> assume the entire force is directed at the surface area of the fist, also assume the fist allows no air through or it could aerodynamically get through.
Surface area of the hand, easy enough to work out, assume no aerodynamic permeating of the surface.
Assume fart 'countermeasure' applies over
Angel Parker
Yeah that’s hypothetically speaking. It’s impossible for a human being but not a fighter jet with an exhaust with the shape of an ass. So answering OP’s question even the strongest of human farts can’t stop a punch, they can blow perhaps a fly away out of their trajectory but nothing more. -physics fag
'Some scientific models are useful, no scientific model is perfect'
You have to assume the sphincter muscle can focus your force onto a pinhead within a moment. Then it's possible. Basically can you focus the death star laser, no shotgun mechanics.
Nathan Foster
Skip this.
>bait
Connor Parker
a punch would not perfectly seal the anus, the fart would still escape
