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

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.

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.

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.

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.

The bullet breaks the fibers, the arrow bites into it and has it's energy dispersed by moving the entire piece.

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

"The slow blade penetrates the shield.” - Gurney Halleck
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 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.

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 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.

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! 😂

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.

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.
@kirbybucks1662

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.

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.

The arrow does not have enough energy to carry it through the wood, but it does have enough to push sand out of the way enough to make a channel in which it can pass through. The bullet is much lighter but travelling much faster with much more energy however due to its speed a number of things occur on impact: it fragments which causes it to become lighter reducing its energy, it also expands going from bullet shape to coin shape making it require a tremendous amount more energy to make it through the bag. Additionally, the bullet tumbles upon impact redirecting its path and reducing its energy.

The speed of the arrow allows it to push the sand away, because it doesn’t develop enough energy to deform. The sand stops the bullets because they do deform, increasing surface tension. The multiple points of contact in the sand, which is at a semi-fluid state creates enough surface tension to stop the deformed, fast moving bullets, where the arrow acts more like a bowling ball. In the 2x4, which is in a solid state, the rigidity of the board has the opposite effect on the slow arrow, but the bullets are moving fast enough to compact the wood fibers, causing them to break tension with each other at a faster rate of speed and with significantly more energy.

The bow and arrow has a lower velocity allowing it to travel through loosely packed materials like sand.

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.

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

Bullets are usually made of lead now unless it’s a full metal jacket which has a copper jacket and lead core. Back in the day bullets were made with steel cores and copper jackets but the trajectory would often cause a ricochet so it was switched to lead so the bullet compressed into the trajectory. As with arrows, they are not made with lead because it would limit penetration power since they do not have as high of a velocity of a bullet. In this case it shows that metal does not absorb the same amount of energy that lead does, thereby allowing the arrow to pass through that sand bag.

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.

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

Energy is mass multiplied by acceleration squared. Inertia is mass multiplied by speed. So the bullet doesn't weigh as much as the arrow but moves way faster. So the bullet has more energy than the arrow, allowing it to go through the wood, but the arrow has more inertia, so it can carry itself through the sandbag.

The wood is basic solid mechanics. Lots of energy makes the wood break, not enough energy and you won't get through. The sand is tricky because being a semi-course powder, it acts as a non-Newtonian fluid, IE. the rate of energy dispersion affects its properties. Because the velocity of the bullet is higher, you can treat the viscosity as higher for the sand, however the arrow has a little bit more mass, so the slower velocity means more pass through with the lower velocity. There is very little mechanical difference between sand and mud.

Penetration and expansion - of course depends on the bullet used BUT the reason is the bag of sand is thicker but less dense than wood. That bag of sand allows for the bullet to expand because of the thickness of the object. Where as a piece of wood (2x4) isn’t thick enough for the bullet to fully expand. It stops the arrow because it is more dense than a bag of sand. This is relative to hitting bone v hitting vitals with an arrow. However, one may hit a bone as large as the brachial plexus with a bullet and quickly un-alive a deer, but may hit the same bone with an arrow & the deer recover & live.

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.

Surface Area. Arrows have a larger surface area at the point of impact compared to bullets. They travel slower and their energy is distributed over a greater area...meaning the arrow doesn't tend to compress mediums like sand as suddenly of forcefully as a bullet.
