The reason the arrow moves through is cuz it does not deform and can push the sand out of the way. The bullet, instead, gets deformed and the energy is absorbed by both moving the sand and deforming the bullet. The wood will not allow the arrow to pass cuz the fibers don't like to move. The bullet, however, is both held together by the surrounding fibers and can focus its energy on the fibers right in front. Hope that makes sense. Edit : see also non-newtonian fluid
No. Lol jk 😆. But yea I can understand difference in the materials behaviors but ngl i was kinda surprised the bullet actually ended up completely stopped in the sand.
Arrows in your pistol is a totally survivable medical condition as long as your butthole doesn't itch. If it does then that means the martians want you back.
The bullet fired from her handgun is most likey 115 grains in weight, moving at around 1000 feet per second. The bullet from her AR is even lighter at around 55 grains and moving at around 3000 feet per second. As stated in her video, the bullets deform on impact and are essentially absorbed by the bag of sand. The mass of the arrow well over 300 grains to nearly 500, traveling at around 300 feet per second with a ridged tip that is closer in size to the round from her AR. With the bag of sand, it's the mass of the arrow that allows it to penetrate the sand. For hard barrier penetration, velocity wins.
You win the right answer award 🏆👏 it's the mass behind the arrow is carrying it through the sand and the speed of the bullet pushes itself through the wood 🎉
Also remember that the lower speed allows the sand to give way to the arrow, while the high speed bullet simply smashes into it. Also, arrows have better penetrating capabilities in general, due to their long and narrow design, which gives them a lot of mass compared to frontal surface area. The arrow of course doesnt have enough energy to break the wood, while the bullet does.
Yeah, OK LOL!!! the 9mm travels around 1500 feet per second... even most 22r travel faster than 1000 feet per second. My air rifle also travels around 1200 feet per second... none of this has anything to do with why the bullet was stopped by the sand and the arrow traveled straight through it. The sand is granular and the wood is solid, if that arrow had a flat tip and not pointed... the sand would have stopped it as well. The aerodynamics of the arrow is what allowed it to pass through and move the grains out of its path instead of trying to push the sand compared to the bullet. The grain of the bullet has no bearing on this.
Heavy and slow penetrates soft targets, light and fast penetrates hard targets. For example, 5.7 defeats body armor but stops early in ballistics gel. 45 ACP FMJs can't defeat the lightest body armor, but pass through a block of gel like it's nothing. Edit: If we're going to make an issue of whether 5.7 penetrates armor, then substitute Liberty Civil Defense 9mm +P, which absolutely penetrates level 3 body armor and is "light and fast".

Question is Energy vs momentum. - Energy is 1/2*mass*velocity squared Momentum is mass*velocity - The arrow has a lot more momentum than the bullet because of the mass, but the bullet has more energy because of the velocity. - Sand is a bunch of loose particles, so it's a transfer of momentum, so penetration is more momentum dependent, so arrows are better. Wood is solid and impacts are more energy dependent, so the bullet is better.
Err heavy slow arrow with solid steel penetrating head ( much more momentum not as much speed, copper jacket not hard enough to push sand aside without compressing Steel jacket or such would have better results

Mythbusters did an entire episode on this but they compared the penetration of different bullet calibers through water. Generally speaker, the faster a bullet goes the less penetration it has through substances that can compress, like water or in this case sand.
Only men understand physics, so they're the ones who have to explain it. Being men, they mansplain to the poor, ignorant but very attractive blonde woman.
I respect that she's observant and inquisitive. Basically the answer is sectional density and its interaction with viscosity along with velocity. An arrow is thin and very long and heavy (300g or so) since sand behaves similar to a fluid (for the purposes of this question) an object moving at a lower speed with a high sectional density will permeate the fluid while retaining more of its energy. A bullet on the other hand goes incredibly fast and has next to no sectional density compared to the arrow will arrest quickly as the semi liquid state of sand acts as a solid. However into a solid wood board the arrow doesn't have the energy to fully pass while the bullet does. The velocity matters much more into a solid than sectional density does. Understanding why things happen is actually really fun.
two things are important to how much damage a projectile does, speed and mass. your arrows are heavier but are slower, your bullets are faster but lighter. Your sand particles needs time to move out of the way, which your arrows provide. Now the wood is different, you need lots of force to break apart the fibers, which your bullets provide
There's two things at play here: 1. At the speed of the arrow, the sand is under *low* pressure and acts as a fluid. At the velocity of the bullet, the sand acts as a solid. 2. Although the arrow goes slower, it has more mass than the bullet and is thus less affected by any slowdown friction within the sand
Best response. I kinda 'got' what was happening but couldn't articulate it. It's like the sand is a non-newtonian fluid. The faster objects create a 'hardening' of the 'fluid'. the wood is a solid, which is broken completely by the higher impact object.
@Raven.flight Viscosity (resistance) of a fluid is proportional to the shear rate (speed you try to move through it) in Newtonian fluids. You get the same effect you describe with regular fluids, calling out non-newtonian fluids doesn't necessarily make the statement true. You described shear-thickening non-newtonian fluids, but there are shear-thinning ones where the the faster you go through it the easier it becomes. Examples of these are ketchup and toothpaste.
Oobleck. Pound your fist on a bag of sand as hard as you can and it’s almost like hitting a rock. Put your finger into the sand and it pushes through much easier.
This is the science of Terminal Ballistics. The number of factors is incredible. The arrow has greater mass and is not generally prone to deformation. Bullets often go fluid (enter Fluid Dynamics and Metallurgy!) on impact and distribute forces over a larger area. Shoot a sandbag with an AP round next for total penetration.
Do any of you get that this is a just a gimmick, or skit for the channel? I’m pretty sure this woman knows exactly how that question is answered… look at the people she’s hanging with. Dude producing the channel and these videos knows his business. Man, they went fishin and caught a ton of big uns! 11k of you all! This channel is all right, think I’m gona subscribe. lol 😝
Mech Engineer here. My best guess is that the sand acts like a non-newtonian fluid (sheer thickening is the propper term), think ooblick, when you shoot the arrow through the sand the individual particles of the sand are given enough time to get out of the way of the arrow and it passes right through. But in the case of the bullet, the individual particles lock together momentarily. Visualize this as the loose sand becoming concrete for a split second and stopping the bullet. The speed required for this effect to take place is inversly proportional to the crossectional area of the projectile. So, if you use something with a bigger crossection than a bullet, like your hand, and pass it through supper slowly you won't have a problem getting through, But if you try slapping the sand you will be stopped dead in your tracts. Hope this made sense, this is by no means my specialty. A civil engineer would be a better person to ask lol.
I had a split second of being super excited you work on giant combat exoskeletons. Then realised "mech" engineer was probs "mechanical". Then I was sad
The loud bangy things have clips with magic shells that can act as a particle or a wave depending on whether a cat is watching it at the moment when you push the triggers. That allow it to decide what to soar through or stop.
Yep. Kinetic energy of an arrow is much higher than a bullet, but velocity is much lower. Harder objects require more velocity to pass through, but softer, less congruent objects require more kinetic energy.
It's all about how the energy is being dispersed. Think of the sand as very small rocks. Too fast into it and it's like hitting a wall. The arrow being heavier and slower swims through it. The wood is not loose as the sand is and it's fibers are not as tough as the sand particles. The bullet breaks the fibers, the arrow bites into it and has it's energy dispersed by moving the entire piece.
This, a better comparison would be a solid stone and a piece of wood. The sand acts more like a fluid, you ever see the difference between a spear gun, a nine mil and a 50 BMG under water? its the difference between jumping into a pool, and jumping off a bridge, but you know, even more extreme.
The bullet flys fast and compacts the sand really tight but the arrow is slower so it doesn’t compress the sand a wood is hard and can’t be compressed so the arrow stops and the bullets go through
It's not just with high velocity impacts. There are certain conditions where sand will behave as a non-Newtonian fluid that are surprising. The Mythbusters found this out when they were trying to replicate quicksand and discovered that just mixing sand and water with various volumes of air would cause sand to act as a non-newtonian fluid! Pretty amazing stuff on that show!
It is more likely that the reason is sound barrier. For supersonic projectiles, inluding ordinary bullets, air molecules and sand as well do not "feel" incoming projectile ahead of time, and will thus cause maximum stopping force. Yet for subsonic 🏹arrows, there is no shockwave, the will be continuous flow structure around projectile, that will try to move apart air particles and sand grains in front of the arrow. Yet that won't work for wood, where fibers keep the obstacle in place... Which turns wood penetration into competition of kinetic energy: 100 Joules of arrow vs 2000 Joules of bullet. At this point I already wish to travel to Texas in order to shoot sandbags with subsonic bullets! 😂
Mass vs Velocity, also a bit of friction involved. The softer sand is able to absorb the impact from the round because there's a high speed, and not a lot of mass to the lead. You have effectively a wider area for the bullet to dump its energy into all at once. The round mushrooms, deforms and then stops, where as the arrow doesn't deform as easily, and has a much greater mass to force the individual sand grains out of the way. The 2x4 on the other hand is a hard target. Hard targets particularly are beaten by speed, although soft targets can be as well. Combine that with the bullet's low surface area, the 2x4 is easily passed through by the bullet while the friction of the arrow and shaft stops it before it can.
The board is one piece, the sand are many pieces. Re:sand: The slower arrow pierces because the sand is able to move away from the path, just like you holding the arrow and plunging it into the sand. Plus, the arrows distribute a much heavier weight over a given cross section. However, the bullets are traveling much faster and when contacting the sand do not allow enough time for the sand the move out of the way. The speed at which the sand is trying could move away increases friction exponentially. The 9 mm bullet design pushes the sand more than divides the sand and the sand in back supports and ever expanding cone of resistance. The 5.56 has a small frontal area that may deform or tumble and the increased compression and friction also prevent depth of penetration. Re: board: The fibers of the board must be broken to penetrate and at such a shallow board the cartridges posses enough ft.lbs of energy to destroy the fibers sufficiently for the bullet to penetrate. This is where the friction of the arrow shaft along the damaged wood fibers of the board is a disadvantage.
Wood fibres bend in direction of missile travel and spring back. A bullet is going fast enough to be gone before the fibre return. An arrow is going slow enough to be there when the fibres start to grip. It’s also long enough for the first fibres to grab further down the shaft. It would be interesting to prove that with an arrow moving at bullet speed. Not sure how you’d achieve that.
So the sand is acting like a fluid with surface tension. When you hit water with enough force, it's just as bad as impacting concrete. But a more gentle insertion has far less resistance.
Terminal ballistics, it’s basically the weight to velocity that determines whether it stops, goes cleanly through, or only goes half way through something
A couple of reasons. 1. Material - A bullet is made to deform after entering a target. And arrow isn't. 2. Area - A 9mm bullet has a bigger diameter and broader nose. While an arrow is made as streamlined as possible to sustain flight. Thus, once it enters the target, it has less friction acting on it. 3. Mass - The bullet is moving faster but it has far less mass than an arrow. Which means that when it deforms, it will lose it's momentum quickly Bullets are designed to not exit targets, while an arrow is designed to penetrate as much as possible, because the bow probably wouldn't have enough power to propel it at speeds where it exists the target
One more thing is that sand is a solid grain by grain, but on a whole it acts like a non-Newtonian fluid meaning it hardens when a large amount of kinetic energy is imparted.
😊 sand soaks up the energy due to the movement of particles bumping into each other while wood has tight grain structure that doesn't allow movement of the particles to dissipate energy.
It has to do with molecule adhesion and surface tension versus kinetic energy, pounds per square inch and friction. There is an interesting ratio of all these that make different materials more resistant to the other penetrative force.
Ikr it just sounds stupid and sexist. Its like pretty much saying all men are stupid and dont explain a anything well. The saddest part is its just copied from media.
Stargate SG1 did a pretty good job at explaining kinetic damage, and velocity. It was the episode with the Nox introduced where bullets could not penetrate the field, but arrows and rocks could.
@@thebreaddealer4942 oh man. Every few years I crack the case and watch SG1. Its a good long month. My favorite episode would be the time loop. Where Oneil slams a golf ball out of this world;)
The average force of an arrow from a compound bow is less than 100 newtons (kg m/s^2) where the force of a bullet is multiple times higher. When penetrating a solid object like the wood, the bullet's higher force allows it to pass through because the energy it transfers into the wood is far less than the energy it started with. The arrow dissipates all of it's energy into the wood and has none left over to pass through so it stops. The sand is a completely different story. The bullet mushrooms out while penetrating the sand, giving it a greater surface area to dissipate it's energy into the sand and so it stops where the arrow does not flatten so it can pass through. There is also the question of inertia because the arrow has more mass than the bullet so for penetrating an object that is thicker, like the sand, the arrow has the upper hand. This is of course only if the arrow can penetrate the object like if you were trying this with concrete. Tldr: the sand acts like a fluid and so takes less force to allow objects through but the bullet flattens and the increased surface area slows it down faster. The wood is just a test of which has more force and the bullet of course wins.
The speed of sound in sand is in-between the speed of the bullet and the arrow. So sand is more like a fluid at the speed of the arrow and more like a solid at the speed of the bullet. Also, wood is far more brittle at high speeds and elastic at low speeds. So, the wood splinters when hit by the bullet, but it can flex a little bit and the dissipate the impact of the arrow.
It has to do with inability of the particles to react and move as fast as the bullet, arrow is designed as a penetration weapon pushes particles away. If you get shot, bullet effects tissue several inches around it. If you get hit with an arrow, the only tissue that sustains damage or injury is in the very very close proximity to the entry wound. When you shoot an arrow at one of those gel blocks, it just goes in.... A bullet practically kicks the block off the table. And I still can't explain it
It works the same way as if you try to push your hand through sand vs. trying to karate chop it. The sand acts similar to a non-newtonian fluid since it's made of fine particles that compress more the faster an object moves.

Like, "mansplain" is a thing that pekoe do against a woman's will because they _assume_ they know more. If someone asks to "mansplain" something, you're not "mansplaining"
The bow and arrow has a lower velocity allowing it to travel through loosely packed materials like sand. The bullet however, has a higher velocity and when it travels through a loose pack material like sand, it's traveling too fast for the sand to move out of its way. The wood is not a loosely packed material. It's tightly packed and very dense
The sand allows transfer of kinetic energy better than wood. The bullet's energy hitting the wood is all localized in the direction of travel. Sand is like hitting pool balls, this slows the bullet and yeah its speed is it's own worst enemy but the arrow is longer and can not be diverted, its also a smaller diameter i think. In essence, the arrow makes up for its momentum with weight whereas the bullet tries to make the same equation equal with speed, leading to it stopping and getting crumpled.
Surface tension fluid dynamics and sectional density. Bullet f goes through wood because it’s a hard surface that shatters and the bullet doesn’t deform, arrow stops because the hard surface is enough to stop the energy from the arrow but not the bullet. The sand has less of a hard stop for the arrow and thus it can penetrate easier, while the surface tension allows it to deform and stop the bullet. There is more resistance over all for the bullet in the sand than the wood, so it stops the bullet, but the wood can absorb more impact so it stops the arrow but not the bullet.
There are many variables involved: Projectile expansion when it hits an object, size of the projectile, velocity, Charge behind the projectile, and the density of the material shot into. The .223 and 9mm have different diameters but loose their potential energy very quickly. The arrow may have a small head, the shaft behind it provides continual mass or kinetic to penetrate the medium and punch on through. With the wood, the initial impact of the arrow is stopped due to the density of the material, which the material is able to overcome. Bullet expansion is the enemy in a losse medium like sand, where the kinetic energy is lost very quickly.
Great questions. I need to do some more homework on this, but Im guessing it has to do with: -Projectile expansion/total projectile energy. -The energy between grain boundaries, the wood being much higher Great video.
In that we live in a nation where we can choose from a number of tools [ at least for now ], we can apply the best tool for each job. God Bless the Republic.
I think a lot of people are missing the fact that sand sort of acts as a non-newtonian fluid. At high speeds, it can't disperse the energy quickly enough so it acts more as a solid (albeit a solid that deforms enough to prevent penetration). But at the lower speed of the arrow, the "particles" have time to move out of the way and allow penetration. Kind of like water. A normal dive allows you to pierce the water easily, but at 60 mph, it's like concrete.
@@bdogplayz I understand that, which is why I said "acts as" instead of "is". That's just the easiest analogy that most people with be familiar enough with. I also specifically used the word "fluid" instead of liquid, since particles of sand act as a fluid in aggregate when we're talking about dynamics, which we are. But yes, you are correct and that might be worth noting for other onlookers.
For all of those of you that keep saying she's not firing the bullets hard enough because she's a girl, please just stop it. Obviously it's true, but we don't want her to start womansplaining her firearm frailties to us.
When sand is compressed it forms a solid and deforms the bullet, making it stop suddenly, as the bullet's change in shape gives it more surface area. The arrow maintains it's shape and pushes the sand aside. The wood is already a solid, and while the bullet deforms, the energy is carried through. The arrow doesn't have the velocity to break the wood, only penetrate.
The arrow doesn't lose as much energy as it goes through the bag because it keeps its shape. Bullet, on the other hand, while moving faster, flatten and spread out upon impact, transferring much of that force onto whatever its hitting. As the bullet spreads, it caused drag, which slows the bullet down enough to lodge into something. It also depends on what you're shooting. Larger rounds tend to do well against soft targets such as a sand bag or body, while smaller rounds tend to do better against hard targets such as armor.
I suspect the same would happen if you shot a hardened undeformable bullet at the sand. But you're right it must have something to do with the energy dissipating sooner. Honestly there's so many different factors involved here that I don't think it's possible to give a complete answer in a YT comment, it would take several hundred words just to outline what's going on.
There’s a few reasons. Such as the fact that the arrow doesn’t deform and keeps its sharp penetrating shape. The next reason is because of the shaft that is able to provide continual momentum through the tunnel that the arrow initially bored into the Sand.
Pretty sure it’s instead because the arrow takes the path of less resistance moving the rice around it while the bullet doesn’t and tries going through each grain
@@fakename3168 part of the reason. But again that’s part of it penetrating. Also it’s not that it’s taking the path of least resistance, rather it has less resistance because it’s frontal surface area is less.
Myth busters did a good episode on this, has to do with the velocity of the object and the media it's being pushed through, much like water, with a slow moving object the sand or water can be pushed out of the way without the object losing much energy, but with a high velocity projectile it's moving to fast to give the sand or water molecules time to move out of the way and in turn acts more like a solid and the projectile losses all it's energy upon impact. Now the wood defeats the arrow because the wood fibers are ridged and can absorb the energy from the arrow without breaking, but like reverse the fibers of the wood can't absorb the energy from the bullet fast enough so they break and the bullet can pass through. Much like body armor can defeat bullets but not a knife
It’s the velocity mixed with the point of impact so for bullets, the point of impact is a bit bigger so it will have problems going through objects that can close behind them like gravel or sand, but it will easily go through wood because it can leave a hole the air goes through saying he’s like because it’s so long by the time One is exiting the other ends just now entering so there’s no place for the sand to stop it as easily but it can’t go through dense things like wood because I can’t split it
Hi, man here, it’s because for the sand you’re not pulling the trigger hard enough. For the wood you’re not releasing the arrow hard enough. Hope this helps 👍🏼
Hey man, follow up question from man here good to meetcha, so in your estimation how can a woman with just a woman's strength pull the trigger as hard as a man? Also, having the shorter arm length and naturally being weaker then a man, would a woman ever be able to fire an arrow as far as a man? Would bedazzling help? Thanks for the Splainin' in advance, you're doing gods work, that's the one true patriarchal god by the way. 🫡
I want to say that most of these comments are wrong. The real reason is the velocity of the projectile; The arrow is moving slower than the bullet so it's able to move the grains of sand out of the way without dissipating all of its energy into the sand. The bullet however is moving at a much higher velocity than the arrow causing its impact to happen faster, compressing rapidly and dissipating its energy with not enough left to travel through the sand. A good way to visualize this is to try punching the sand at the beach; it'll feel like punching a wall yet if you slowly move your hands through it, the sand moves with almost no effort; The same thing can be said for water and is the reason why firearms aren't used underwater and harpoons and spearguns are used instead.
Then why can a tornado shove a piece of straw through a brake drum? That's high velocity AND it is straw. I'm actually just trolling. There comes a point velocity overtakes. You can kill shooting a gun underwater. It doesn't have the same range, but it will and can kill. Yes, trolling again...
The reason the arrow moves through is cuz it does not deform and can push the sand out of the way. The bullet, instead, gets deformed and the energy is absorbed by both moving the sand and deforming the bullet.
The wood will not allow the arrow to pass cuz the fibers don't like to move. The bullet, however, is both held together by the surrounding fibers and can focus its energy on the fibers right in front.
Hope that makes sense.

Question is Energy vs momentum.
-
Energy is 1/2*mass*velocity squared
Momentum is mass*velocity
-
The arrow has a lot more momentum than the bullet because of the mass, but the bullet has more energy because of the velocity.
-
Sand is a bunch of loose particles, so it's a transfer of momentum, so penetration is more momentum dependent, so arrows are better.
Wood is solid and impacts are more energy dependent, so the bullet is better.

I respect that she's observant and inquisitive.
Basically the answer is sectional density and its interaction with viscosity along with velocity. An arrow is thin and very long and heavy (300g or so) since sand behaves similar to a fluid (for the purposes of this question) an object moving at a lower speed with a high sectional density will permeate the fluid while retaining more of its energy. A bullet on the other hand goes incredibly fast and has next to no sectional density compared to the arrow will arrest quickly as the semi liquid state of sand acts as a solid.
However into a solid wood board the arrow doesn't have the energy to fully pass while the bullet does. The velocity matters much more into a solid than sectional density does.
Understanding why things happen is actually really fun.
not everything is mansplaining, it's literally just explaining.
two things are important to how much damage a projectile does, speed and mass. your arrows are heavier but are slower, your bullets are faster but lighter. Your sand particles needs time to move out of the way, which your arrows provide. Now the wood is different, you need lots of force to break apart the fibers, which your bullets provide
best and most logical answer here
There's two things at play here:
1. At the speed of the arrow, the sand is under *low* pressure and acts as a fluid. At the velocity of the bullet, the sand acts as a solid.
2. Although the arrow goes slower, it has more mass than the bullet and is thus less affected by any slowdown friction within the sand
Best response. I kinda 'got' what was happening but couldn't articulate it.
It's like the sand is a non-newtonian fluid. The faster objects create a 'hardening' of the 'fluid'.
the wood is a solid, which is broken completely by the higher impact object.
Are you to just seeing who can use the bigger word?
@Raven.flight Viscosity (resistance) of a fluid is proportional to the shear rate (speed you try to move through it) in Newtonian fluids. You get the same effect you describe with regular fluids, calling out non-newtonian fluids doesn't necessarily make the statement true. You described shear-thickening non-newtonian fluids, but there are shear-thinning ones where the the faster you go through it the easier it becomes. Examples of these are ketchup and toothpaste.
Oobleck. Pound your fist on a bag of sand as hard as you can and it’s almost like hitting a rock. Put your finger into the sand and it pushes through much easier.
Bro "slowdown friction"? Its just called friction
This is the science of Terminal Ballistics. The number of factors is incredible. The arrow has greater mass and is not generally prone to deformation. Bullets often go fluid (enter Fluid Dynamics and Metallurgy!) on impact and distribute forces over a larger area. Shoot a sandbag with an AP round next for total penetration.
"big AR-15..." Made me laugh. That's the exact energy that sees Black, Rails and Attachments make a gun MORE ballistic xD

The sarcasm is heavy with this one lol
the question you have to ask is "how does the energy get dissipated"
Mech Engineer here. My best guess is that the sand acts like a non-newtonian fluid (sheer thickening is the propper term), think ooblick, when you shoot the arrow through the sand the individual particles of the sand are given enough time to get out of the way of the arrow and it passes right through. But in the case of the bullet, the individual particles lock together momentarily. Visualize this as the loose sand becoming concrete for a split second and stopping the bullet.
The speed required for this effect to take place is inversly proportional to the crossectional area of the projectile. So, if you use something with a bigger crossection than a bullet, like your hand, and pass it through supper slowly you won't have a problem getting through, But if you try slapping the sand you will be stopped dead in your tracts.
Hope this made sense, this is by no means my specialty. A civil engineer would be a better person to ask lol.

Simple yet all the info I needed haha.
@@wiki3661 I'd also mention different material properties from what is being shot but yeah pretty much.
Yep. Kinetic energy of an arrow is much higher than a bullet, but velocity is much lower. Harder objects require more velocity to pass through, but softer, less congruent objects require more kinetic energy.
@@cathodd2442no, the energy of the bullet is higher than the arrow has. The momentum is lower though.
@Sauromannen ah yeah you're right. I got the two mixed up. (Kinetic energy and momentum)
It's all about how the energy is being dispersed.
Think of the sand as very small rocks. Too fast into it and it's like hitting a wall. The arrow being heavier and slower swims through it.
The wood is not loose as the sand is and it's fibers are not as tough as the sand particles. The bullet breaks the fibers, the arrow bites into it and has it's energy dispersed by moving the entire piece.
This, a better comparison would be a solid stone and a piece of wood. The sand acts more like a fluid, you ever see the difference between a spear gun, a nine mil and a 50 BMG under water? its the difference between jumping into a pool, and jumping off a bridge, but you know, even more extreme.
Nicely mansplained! : )
@@jonathanbrown7250not mansplaining when its a logical expalanation
The bullet flys fast and compacts the sand really tight but the arrow is slower so it doesn’t compress the sand a wood is hard and can’t be compressed so the arrow stops and the bullets go through
The vibe I get is that she knows very well the science behind it 😎
At high velocity’s, the sand starts to behave like a non-Newtonian fluid.
It's not just with high velocity impacts.
There are certain conditions where sand will behave as a non-Newtonian fluid that are surprising. The Mythbusters found this out when they were trying to replicate quicksand and discovered that just mixing sand and water with various volumes of air would cause sand to act as a non-newtonian fluid!
Pretty amazing stuff on that show!
It is more likely that the reason is sound barrier. For supersonic projectiles, inluding ordinary bullets, air molecules and sand as well do not "feel" incoming projectile ahead of time, and will thus cause maximum stopping force.
Yet for subsonic 🏹arrows, there is no shockwave, the will be continuous flow structure around projectile, that will try to move apart air particles and sand grains in front of the arrow. Yet that won't work for wood, where fibers keep the obstacle in place... Which turns wood penetration into competition of kinetic energy: 100 Joules of arrow vs 2000 Joules of bullet.
At this point I already wish to travel to Texas in order to shoot sandbags with subsonic bullets! 😂

The self restraint to not give a. Two hour lecture right here
Mass vs Velocity, also a bit of friction involved. The softer sand is able to absorb the impact from the round because there's a high speed, and not a lot of mass to the lead. You have effectively a wider area for the bullet to dump its energy into all at once. The round mushrooms, deforms and then stops, where as the arrow doesn't deform as easily, and has a much greater mass to force the individual sand grains out of the way. The 2x4 on the other hand is a hard target. Hard targets particularly are beaten by speed, although soft targets can be as well. Combine that with the bullet's low surface area, the 2x4 is easily passed through by the bullet while the friction of the arrow and shaft stops it before it can.
The board is one piece, the sand are many pieces.
Re:sand: The slower arrow pierces because the sand is able to move away from the path, just like you holding the arrow and plunging it into the sand. Plus, the arrows distribute a much heavier weight over a given cross section.
However, the bullets are traveling much faster and when contacting the sand do not allow enough time for the sand the move out of the way. The speed at which the sand is trying could move away increases friction exponentially. The 9 mm bullet design pushes the sand more than divides the sand and the sand in back supports and ever expanding cone of resistance. The 5.56 has a small frontal area that may deform or tumble and the increased compression and friction also prevent depth of penetration.
Re: board: The fibers of the board must be broken to penetrate and at such a shallow board the cartridges posses enough ft.lbs of energy to destroy the fibers sufficiently for the bullet to penetrate. This is where the friction of the arrow shaft along the damaged wood fibers of the board is a disadvantage.
that's the good shit right here
Wood fibres bend in direction of missile travel and spring back. A bullet is going fast enough to be gone before the fibre return. An arrow is going slow enough to be there when the fibres start to grip. It’s also long enough for the first fibres to grab further down the shaft.
It would be interesting to prove that with an arrow moving at bullet speed. Not sure how you’d achieve that.
@@davidelliott5843an air gun. But the solution could also be more mass too. An iron bolt from a cross bow probably would go through.
So the sand is acting like a fluid with surface tension. When you hit water with enough force, it's just as bad as impacting concrete. But a more gentle insertion has far less resistance.
From the looks of the impact of that AR-15, it's chambered in .22LR and not 5.56x45mm (.223 for any americans)
Years ago, an article in Black Belt Magazine demonstrated: kevlar vests don't stop classical martial arts weapons.
Terminal ballistics, it’s basically the weight to velocity that determines whether it stops, goes cleanly through, or only goes half way through something
A couple of reasons.
1. Material - A bullet is made to deform after entering a target. And arrow isn't.
2. Area - A 9mm bullet has a bigger diameter and broader nose. While an arrow is made as streamlined as possible to sustain flight. Thus, once it enters the target, it has less friction acting on it.
3. Mass - The bullet is moving faster but it has far less mass than an arrow. Which means that when it deforms, it will lose it's momentum quickly
Bullets are designed to not exit targets, while an arrow is designed to penetrate as much as possible, because the bow probably wouldn't have enough power to propel it at speeds where it exists the target
Or magic
One more thing is that sand is a solid grain by grain, but on a whole it acts like a non-Newtonian fluid meaning it hardens when a large amount of kinetic energy is imparted.
Thanks so I didn’t have to explain it
Also, the arrow tip is hardened steel. Use of tungsten armor penetrator rounds would yield similar results from the rifle to the sand bag etc.

😊 sand soaks up the energy due to the movement of particles bumping into each other while wood has tight grain structure that doesn't allow movement of the particles to dissipate energy.
It has to do with molecule adhesion and surface tension versus kinetic energy, pounds per square inch and friction. There is an interesting ratio of all these that make different materials more resistant to the other penetrative force.

Epic show
Teal c getting door checked. Lol you have said that many times before.
The average force of an arrow from a compound bow is less than 100 newtons (kg m/s^2) where the force of a bullet is multiple times higher. When penetrating a solid object like the wood, the bullet's higher force allows it to pass through because the energy it transfers into the wood is far less than the energy it started with. The arrow dissipates all of it's energy into the wood and has none left over to pass through so it stops.
The sand is a completely different story. The bullet mushrooms out while penetrating the sand, giving it a greater surface area to dissipate it's energy into the sand and so it stops where the arrow does not flatten so it can pass through.
There is also the question of inertia because the arrow has more mass than the bullet so for penetrating an object that is thicker, like the sand, the arrow has the upper hand. This is of course only if the arrow can penetrate the object like if you were trying this with concrete.
Tldr: the sand acts like a fluid and so takes less force to allow objects through but the bullet flattens and the increased surface area slows it down faster. The wood is just a test of which has more force and the bullet of course wins.
your answer sounds the most 👍 right too me

“mansplaining”
@@toyotaAETruenoGT-APEX Sorry I just meant to answer the question to the best of my knowledge
What he said 👆🏽😂 yup!
There's only one thing to do now, get a bow that shoots bullets.
The speed of sound in sand is in-between the speed of the bullet and the arrow. So sand is more like a fluid at the speed of the arrow and more like a solid at the speed of the bullet. Also, wood is far more brittle at high speeds and elastic at low speeds. So, the wood splinters when hit by the bullet, but it can flex a little bit and the dissipate the impact of the arrow.
I hate that I can't come up with the words to explain what I know.
It has to do with inability of the particles to react and move as fast as the bullet, arrow is designed as a penetration weapon pushes particles away.
If you get shot, bullet effects tissue several inches around it. If you get hit with an arrow, the only tissue that sustains damage or injury is in the very very close proximity to the entry wound.
When you shoot an arrow at one of those gel blocks, it just goes in.... A bullet practically kicks the block off the table. And I still can't explain it
Me
It works the same way as if you try to push your hand through sand vs. trying to karate chop it. The sand acts similar to a non-newtonian fluid since it's made of fine particles that compress more the faster an object moves.
I like this answer the most because I know exactly how bad it can hurt to chop sand.

Why in an emergency is it women and children first ? So men can come up with a solution in peace and quiet.
The bow and arrow has a lower velocity allowing it to travel through loosely packed materials like sand. The bullet however, has a higher velocity and when it travels through a loose pack material like sand, it's traveling too fast for the sand to move out of its way. The wood is not a loosely packed material. It's tightly packed and very dense
Thank you, finally someone got it!
The sand allows transfer of kinetic energy better than wood. The bullet's energy hitting the wood is all localized in the direction of travel. Sand is like hitting pool balls, this slows the bullet and yeah its speed is it's own worst enemy but the arrow is longer and can not be diverted, its also a smaller diameter i think. In essence, the arrow makes up for its momentum with weight whereas the bullet tries to make the same equation equal with speed, leading to it stopping and getting crumpled.
I love how she immediately made herself put to be insufferable. “Mansplain this for me internet”
Surface tension fluid dynamics and sectional density. Bullet f goes through wood because it’s a hard surface that shatters and the bullet doesn’t deform, arrow stops because the hard surface is enough to stop the energy from the arrow but not the bullet. The sand has less of a hard stop for the arrow and thus it can penetrate easier, while the surface tension allows it to deform and stop the bullet. There is more resistance over all for the bullet in the sand than the wood, so it stops the bullet, but the wood can absorb more impact so it stops the arrow but not the bullet.
There are many variables involved: Projectile expansion when it hits an object, size of the projectile, velocity, Charge behind the projectile, and the density of the material shot into. The .223 and 9mm have different diameters but loose their potential energy very quickly. The arrow may have a small head, the shaft behind it provides continual mass or kinetic to penetrate the medium and punch on through. With the wood, the initial impact of the arrow is stopped due to the density of the material, which the material is able to overcome. Bullet expansion is the enemy in a losse medium like sand, where the kinetic energy is lost very quickly.
The spice must flow.
nope its from the sand acting as a larger sold under compression.
my shaft provides continual mass and kinetic energy to help penetrate the medium as well.
Fuck these guy thanks for the explanation
Great questions.
I need to do some more homework on this, but Im guessing it has to do with:
-Projectile expansion/total projectile energy.
-The energy between grain boundaries, the wood being much higher

I think a lot of people are missing the fact that sand sort of acts as a non-newtonian fluid. At high speeds, it can't disperse the energy quickly enough so it acts more as a solid (albeit a solid that deforms enough to prevent penetration). But at the lower speed of the arrow, the "particles" have time to move out of the way and allow penetration.
Kind of like water. A normal dive allows you to pierce the water easily, but at 60 mph, it's like concrete.
your spot on man.
Btw sand is considered a non Newtonian soling not a liquid but you got it on point
@@bdogplayz I understand that, which is why I said "acts as" instead of "is". That's just the easiest analogy that most people with be familiar enough with.
I also specifically used the word "fluid" instead of liquid, since particles of sand act as a fluid in aggregate when we're talking about dynamics, which we are.

@@leopard2a786 I paired it with the level and type of humor in the video. I find it most complimentary.
When sand is compressed it forms a solid and deforms the bullet, making it stop suddenly, as the bullet's change in shape gives it more surface area. The arrow maintains it's shape and pushes the sand aside. The wood is already a solid, and while the bullet deforms, the energy is carried through. The arrow doesn't have the velocity to break the wood, only penetrate.
The bullet is so hot that it creates glass and it stops it.

True but its more accurate to say ballistics
That's why a sandbag bunker is reasonably safe.....especially when it is wet.
I'm wearing my homemade sand-bag body armor now, I'm unstoppable!
Unless you have arrows.
The arrow doesn't lose as much energy as it goes through the bag because it keeps its shape. Bullet, on the other hand, while moving faster, flatten and spread out upon impact, transferring much of that force onto whatever its hitting. As the bullet spreads, it caused drag, which slows the bullet down enough to lodge into something. It also depends on what you're shooting. Larger rounds tend to do well against soft targets such as a sand bag or body, while smaller rounds tend to do better against hard targets such as armor.
I suspect the same would happen if you shot a hardened undeformable bullet at the sand. But you're right it must have something to do with the energy dissipating sooner.
Honestly there's so many different factors involved here that I don't think it's possible to give a complete answer in a YT comment, it would take several hundred words just to outline what's going on.
Todd’s workshop did a whole segment on this with an American TH-camr doing the firearms part.
came here to say this lol.
Arrows has specific tips for penetration and speed where bullets have power but no penetration
Speed of bullet go brrrrr. Sand go shhhhhhhh. Speed of arrow go shhh, sand is not amused.
There’s a few reasons. Such as the fact that the arrow doesn’t deform and keeps its sharp penetrating shape. The next reason is because of the shaft that is able to provide continual momentum through the tunnel that the arrow initially bored into the Sand.
Pretty sure it’s instead because the arrow takes the path of less resistance moving the rice around it while the bullet doesn’t and tries going through each grain
@@fakename3168 part of the reason. But again that’s part of it penetrating. Also it’s not that it’s taking the path of least resistance, rather it has less resistance because it’s frontal surface area is less.
Myth busters did a good episode on this, has to do with the velocity of the object and the media it's being pushed through, much like water, with a slow moving object the sand or water can be pushed out of the way without the object losing much energy, but with a high velocity projectile it's moving to fast to give the sand or water molecules time to move out of the way and in turn acts more like a solid and the projectile losses all it's energy upon impact. Now the wood defeats the arrow because the wood fibers are ridged and can absorb the energy from the arrow without breaking, but like reverse the fibers of the wood can't absorb the energy from the bullet fast enough so they break and the bullet can pass through. Much like body armor can defeat bullets but not a knife
This woman seriously said mansplain 💀💀💀
When/where did she say that? I can't find it. The closest I can find is at the very beginning but she says "Now explain this to me, internet."
It’s the velocity mixed with the point of impact so for bullets, the point of impact is a bit bigger so it will have problems going through objects that can close behind them like gravel or sand, but it will easily go through wood because it can leave a hole the air goes through saying he’s like because it’s so long by the time One is exiting the other ends just now entering so there’s no place for the sand to stop it as easily but it can’t go through dense things like wood because I can’t split it
Hi, man here, it’s because for the sand you’re not pulling the trigger hard enough. For the wood you’re not releasing the arrow hard enough. Hope this helps 👍🏼

🤣😂🤣😂🤣
That's bs
Pulling the trigger harder does not increase fps on a bullet, really? Haha
I want to say that most of these comments are wrong.
The real reason is the velocity of the projectile; The arrow is moving slower than the bullet so it's able to move the grains of sand out of the way without dissipating all of its energy into the sand.
The bullet however is moving at a much higher velocity than the arrow causing its impact to happen faster, compressing rapidly and dissipating its energy with not enough left to travel through the sand. A good way to visualize this is to try punching the sand at the beach; it'll feel like punching a wall yet if you slowly move your hands through it, the sand moves with almost no effort; The same thing can be said for water and is the reason why firearms aren't used underwater and harpoons and spearguns are used instead.
Then why can a tornado shove a piece of straw through a brake drum? That's high velocity AND it is straw. I'm actually just trolling. There comes a point velocity overtakes.
