well considering the speed and power of this Air Rifle i whould suggest to meake a SABO round. it is akcualy easy to meake you just 3d print it or ask Bob from K3D to Metal 3d print one or just normal 3d print with a metal core and the sabot. you could just 3d print the sabot and just meake the dart, there are 2 Sabo rounds (wich one i know) APDS and APSDFS. it whould be cool to see this Not so Nerf shoot projectile like this aspecialy with the slow mo from you guys! :D
this has the same energy as: "the neighbours are having a water balloon fight" "waiting for the water to boil" edit: waiting for mike shake to notice me 😃
Small town italian police must be very happy to know one of their neighbor just developed and is in possession of the cheapest long-range lethal weapon ever
@skyk3624 You are right about that, but the ammo is incredibly cheap and, if the process of making the weapon was automated and some agents were eliminated like you do when you manufacture an actual weapon for mass distribution, then i supose it would be directly or at least over time the cheapest weapon ever
@MarcusChaminade i would also consider the fact that 22 lr is cheap this weapon wasnt range tested and gun auctions sell rifles extremly cheap also the lethal ammo is more expensive
Hey Mike! I study Aerospace and work on aircraft. One reason why you might have had a problem reaching Mach 1 is because of drag increasing as you get closer to Mach 1. So, reducing the cross section area of the foam darts to improve transonic performance might help. Additionally, the moments of inertia for a bullet with 2 different bullet materials might be the reason why the foam darts disintegrated. In theory, you'll need to make sure that the bonding material is able to handle the stresses and strains of the moment of inertia much better. I'm still a student, so I might be completely wrong, but trying with these improvements might help.
The bonding isn't the failing point. The dart's foam shreds the moment it leaves the barrel, causing a sudden increase in surface area amongst other issues. Essentially, the tip is dragging the foam because the bond held, and the foam didn't completely fail, causing rapid deceleration. That's why the taped dart preformed so much better.
I'm also in aerospace but I work on rockets. I don't think transonic effects is the explanation for not hitting Mach 1 since you don't have the same aerodynamic effects inside the barrel vs outside in free flow. The flow domain is completely different. Also the cross section area of the bullet is fixed because of the barrel inner diameter. What you should do to maximize the velocity is: 1. Increase pressure so you have more initial energy available to accelerate the projectile. 2. Increase barrel length so the gas can do more work on the projectile before it leaves the barrel (at some point this stops working because too much pressure building up in front of the bullet). 3. Seal the projectile against the barrel better so more of the energy of the expanding gas goes into the bullet instead of around it (as in the case of the foam blowing up in the barrel). 4. Decrease bullet mass: less mass=more speed for the same energy input. Though this is a trade off against decreasing your ballistic coefficient. 5. Reduce friction in the barrel. Look up "Firearm energy efficiency"
It's simpler than that, foam isn't going to stand up to the pressure. It's shredding trying to force the heavier tip through the air, which at higher speeds has a lot of resistance.
@FazeParticles Some countries classify anything over a certain power a "firearm". Under UK law this would definitely be a firearm, which you need a licence for. Probably similar in Italy.
@notfullyplaced8281 it's an air rifle I don't think ATF has jurisdiction over those. They don't require a license or anything either, check out demolition ranch his video on air guns.
A lot of modern tanks have smooth-bore guns (no rifling). To shoot a stable round, their ammunition has fins and a sabot that discards during flight (APFSDS). I think it would be cool to try and make one of these rounds and test it with this gun. Great video!
But there’s a reason why those are smooth bores mainly because of the ammunition. The ammunition used these days are far quicker and reaches stabilisation due to how those are designed. Smooth bore helps it slow it down thus retaining effectiveness.
@patrickiamonfire965 I thought tank guns were smoothbore because it specifically made the darts go faster and allows them to be longer aka more effective against armor with long rounds spin just causes tumbling, so fins are more effective for stabilization
@arctan4547 well , APFSDS(armour piercind fin stabilised discarded sabot) its simply a metal rod encased in a sabot , it flies fast and straight and are designed to be effective against modern tank armor because speed beats armor, british tanks still use riffled barrels in their tanks. and yea, trying to design an sabot round for a bore that small , it will be pretty tricky
@Pita-o8b did you not see him use an air pump to pressurize it? Reloading and readying the next shot would suck, but for hunting or scaring off scavengers it would do the trick
Eh, this wouldn't even raise an eyebrow in the states. Airguns are completely unregulated here, and there are more powerful ones you can order delivered straight to your front door. With actual rifled barrels so you can hit something more than 5 feet away.
Just a tip for the rifled bullet (from someone working in the industry and talking with many ballisticians) the reference footage of the bullet that you put into the video is 8.6 blackout, one of the fastest twist rates of any bullet manufactured today. Looking at the spirals of your printed bullet, they are WAY too steep (they have far too many rotations per inch) and you may be getting serious destabilization due to it. Try it again, but this time calculate a twist rate on the projectile for a 1:10 twist rate. (One full twist every 10 inches). Other inspiration can be had by looking up "rifles 20ga slugs" and mimicking some of the design choices.
Agreed, and even compared to the 8.6 blackout comparison in the video, the angle of the grooves on the 3D printed one looks to be ~45° or maybe more, while the 8.6BLK is maybe 10-20° on a quick glance. What he made is a screw, not a rifling. =)
....ballisticians...my new favourite word....sounds like people who design men's banana hammocks to keep things in place...how am I going to work this word into a casual conversation ? 😁
You just reinvented the Girandoni Air rifle carried on the Lewis and Clark expedition. Some were used as sniper rifles. Invented in 1779 by an Italian.
That one had a 26 round detachable magazine. An "assault weapon" made when the founding fathers were alive Thomas Jefferson bought one for the Lewis and Clark expedition
I think the best projectile to use would be metal balls like in old flintlock guns, rotation wouldn't be a problem and you could get a better seal by rapping the projectile in paper like they did as well. I know it's not as cool as over engineered bullet designs with fins and all, but most of the time simplicity is pretty effective. There is a reason for most of the commercially available air guns to shoot spheres.
@PapaDidi-k8j well, as I said there are many real guns that uses round bullets. Sharpness can help with penetration if you can get it to fly reliably straight, but as you can see in the video, what makes the big difference is mass. What makes airguns less lethal is mostly the lesser force generated, due to a lighter projectile and lesser pressure of the co2 cartridge. The shape of the projectile is such a small factor in comparison. Also it is easier to feed round bullets to a chamber because orientation doesn't matter.
@D_Boone you're right they used cloth with flintlocks, paper was used later with old revolvers like the Lemat and Colt navy before bullet casings were a thing. I mixed it up by mistake 😅 And yeah, rotation would still help with getting a more stable and straight trajectory. When I said rotation I meant misalignment, if the round rotated out of alignment it would't be an issue because there is no tip in the bullet.
@Zx_Z3r0 Well another alternitve would be a minae ball. With its hollow base there might be enough pressure to cause it to expand out giving a better seal. Also it has the benefit of being lighter in the rear and heavier at the nose which would also help some with stability. Ultimately without rifling stability is aalways going to be an issue for any lead bullet without the exception of lead balls. He also could try elctro etching with saltwater and a battery in the last 4 to 6 inches of the barrel creating starline choke. This is more common in countries like russia where its easier to get a "shotgun" than a rifle.
Yeah, if they don't make this in the first place, someone else is gonna make this. Especially if you don't get detected with real ammo and real sniper. Because they can create it by themselves if you are experts crafter
Pretty cool. When I was a firefighter, we discovered that the end of a 3/8 inch length of white pvc pipe fit exactly onto the threaded end of a 2,200lb pressure air pack tank. We used to make darts out of 10 penny 2 3/4 inch framing nails with paper cups and duct tape. One guy would aim the open end of the pipe, and the other would crack open the valve. It could shoot that dart clean through the doors of a junk car we used to practice auto extraction on 20 feet away.
I think a ported barrel might fix your darts blowing apart. There is a cavity in the dart that is pressurized in the barrel, but the dart is supported on the outside by the barrel. Once the front of the dart exits the barrel, it is no longer supported but still has that pressure inside until the back of the bullet exits the barrel, releasing this pressure. A ported barrel would release this pressure while the dart is still supported by the barrel, possibly keeping the dart together.
I’m glad you saw that too hopefully he sees ur comment i was thinking he should fill the hole since he doesn’t need it and hopefully that will stop that
@jaredfritsch6833depends on how many times you plan on firing it, because it’s not like you’d be able to just reuse the reinforced darts due to being flung into objects at excessively high speeds
@jaredfritsch6833 yes, but I was trying to come up with something that kept the stock unmodified. So, all things being equal the dart being fired is identical to one you ahoot from the toy.
The longer barrel allows more time for the darts to accelerate, so that is actually a huge impact. Also kinda interesting that you still got it to supersonic despite a shorter barrel.
@Knight_Night25After watching 3 years of Ukraine war videos I have learned the human body is FAR more resilient than you think. People survive stuff you wouldn't ever think possible. I've seen people survive multiple grenade blasts from drones right by them. The mortality rate of gunshot wounds to the head is around 93% but people do survive shots like these from time to time.
So I just watched this, and remembered a similar video TheBackyardScientist made back in 2018, where he actually explained the reason the nerf darts destroy themselves when shot with high pressure air. Essentially, instead of pushing only on the back of the dart, the air enters the center hole that's used to center the darts in a nerf blaster, and then expands extremely quickly, which shreds the darts, and is also why the head of the half-length dart flew off. The way to solve it is actually pretty simple, just plug the hole with something like an ear plug, which prevents the air from getting inside the dart and tearing it apart.
Yeah! I mentioned that video in the part 1. We tried using an earplug and the dart didn’t break, but the speed was also lower compared to not having it
lol what? We literally proved a dart went supersonic. I just said with an earplug the dart was flying slower. Chronographs are much less accurate than the distance/time method
@meikgeik That's not what they said. They said they tried but that it caused slower speed. If you use logic you can realize that they did not add that attempt because they already verified that it was not beneficial. In a project you always show the tests that work, not necessarily you show bugs or tests that you consider unnecessary
For a point of comparison, a 22 Long Rifle cartridge has about 160 to 170 joules of energy as it leaves the barrel. Although not recommended for combat/defense, a 22 LR _will_ kill. This gizmo you've created is no joke.
==UPGRADE TIP== you need to use a faster opening valve like a solenoid to help actuate the primary qev faster. Also consider using a smaller secondary QEV between the primary and the pilot trigger at least for faster actuation = more power
Solenoids usually have very small holes inside and I'm pretty sure he already tried it in previous video. The actual best valve for this is a burst disk
@linecraftman3907 It's been a while since I watched his original video, but I think the solenoid released air too rapidly and caused the darts to disintegrate inside the barrel, so he switched to this. Might have worked better for these lead projectiles though.
The real problem is that compressed air at room temperature travels at the speed of sound at room temperature. To exceed the speed of sound, you have to use hot air.
Rifling is dependent on weight and speed of the projectile to create stabilization of the projectile. In same, weight, design and balance of a technical pellet also creates stabilization. The lead loads would have stabilized with more FPS, a marble would have been a great projectile to test here as it has less limitations to these effects. 9/10, because your curiosity makes fantastic content in itself, with your voice selling it without doubt! Fact alone you did not stop to get that supersonic Nerf Dart is a huge win!
Hey mike i have a suggestion that would make your device much more powerful without any changes on the hardware. First a bit of theory to explain my suggestion: A gas under pressure can only expand at the speed of sound in said gas. If pressure increases beyond the point the gas can move away from the point of high pressure, so if it still tries pushing away beyond the gas front reaching the speed of sound, the gas just bunches up on the gas front and creates what we know as a shock wave. If we use air under pressure to accelerate our projectile the theoretical maximum velocity of the dart can not be more than the speed of sound. If the dart is traveling at the speed of sound the gas behind the dart pushing it forward can not move any faster itself. Even with a million psi behind it it would not go faster than the speed of sound. Now my suggestion: You could use a gas that has a higher specific speed of sound. Helium for example is not too expensive, available for purchase to anyone and the speed of sound in it at normal temperatures is a whopping 3500 km/h! Which would be your new theoretical maximum speed for the projectile. You could also heat the gas you are using, because the speed of sound of a gas increases with temperature. Thats how regular firearms do it. The chemical reaction of the propellants release mainly CO2 which then pushes the projectile through the barrel. But CO2 has a speed of sound very similar to air, so why are firearm projectiles so fast? Its because the CO2 leaves the chemical reaction very very hot which increases its speed of sound dramatically and makes firearm projectile speeds possible. Be careful with heating pressure vassals though, because increasing the temperature both increases the pressure and lowers the tensile strength of the material the vassal is made of. So, dont blow yourself up and use warm helium and a long barrel to reach crazy speeds. For the maximum possible pull a vacuum in the barrel, so the dart doesnt have to push away the air in front of it when traveling down the barrel. To recap: Use Helium to pressure the tank. Make sure the gas isnt cold. Use a long barrel. Pull a vacuum on the barrel if you can. Do this and you should reach projectile speeds around 970 m/s.
NASA uses air guns to test material strength and impact dynamics using just regular air mix . They use up to 20k psi and a vacuum pulled on the barrell to enable rapid expansion of the gas. Using these methods, they can get a 3mm steel BB up to Mach 7.
I disagree with your statement about not being able to use air. Here is my explanation. This is a pretty basic fluid dynamics system, we have a pressure chamber with an outlet. With the barrel acting as a simple nozzle, the fluid (and therefore projectile) leaves the barrel at a lower pressure but higher velocity. So if our goal is to have exit velocity greater than the speed of sound you will need a supersonic nozzle to accelerate that fluid past that point. These convergent divergent nozzles are how rocket engines work, it just takes a lot of energy to get the fluid up to those velocities (but in your example a MilLioN pSi cOulDNt bReAK thE sOuNd BArriEr) I’m just poking fun at it, but seriously we have been expanding gas across nozzles for a while and is always the solution for increasing velocity.
What are you talking about with "pulling a vacuum"? You do not want a sealed system in any projectile-firing device like this in FRONT of such pressures. Unless you literally mean putting a vacuum machine's nozzle to near the barrel, creating positive pressure in front. Not literally a vacuum, though. I should look this up.
@adamsazaquatics3079 a gas can be accelerated to supersonic speeds, but it will not expand at super sonic speeds by itself without trickery. Supersonic nozzels perform very bad against backpressure. If the gas cant freely or relatively freely leave the nozzel, but instead runs into a barrel blocked by a projectile which creates high static pressure behind the nozzel it will not work as intended and instead effectively only reduce flow rate. In theory you could have a very long barrel and slowly approach the projectile to speeds at which the gas can leave the nozzel with less backpressure building up at which point it would function normal again and push the projectile at supersonic speeds. But my guess is that the barrel would need to be so long that the barrel walls would provide enough friction to the gas along its path down the barrel to the projectile that it would shlow the gas down significantly. In other words, i dont think that would work at all. And of course that would require very precise and expensive nozzels and other hardware to make the super sonic gas flow a reality. Instead he could just put helium in his existing machine and achieve supersonic speeds. Low cost and effort. Kind of ironic that you laugh at my proposal and then propose a complicated, expensive and likely not functional alternative.
I'm remembering why the pneumatic rifle and pneumatic crossbow are my favorite weapons in Metro... No significant sound, head explosion. A stealth dream. Conquering Pripyat with a nerf rifle.
Eye roll , while no hearing protection is needed, I have a PCP rifle, it is really loud. No stealth in real life with big bore weapons without a real suppressor.
18:54-18:57 that's so cool. The bullet went in perfectly straight forward and seemed to come out the other side completely flipped around. The extra damage the projectile would do while spinning inside adds ever more carnage.
Not only that, the penetrative power was so strong, it didn't push the dummy head off the table like the other ones, just went through like a knife through butter.
@deathlordicelord8402 no not tanks anymore, they shoot an APFSDS (armour piercing fin stabilised discarding sabot) round that doesn't explode, just tears through the tank and fragments
I think the hose between the small tank and QEV is what gave you supersonic darts. That extra distance gives the dart time to speed up without just ripping it in half, and makes it able to reach higher speed. That's my theory, anyway.
The videos where you were learning new skills and showing that consistency and not giving up are so important were so inspirational for me, I hope you go back to those occasionally. You said once and it really moved me: "I will keep trying and if I can't I'll die trying"
I've been subbed to Ballsitic High Speed for awhile. For those who haven't seen it, you may still be able to watch Adam get blown up by a faulty RPG. That one put him down for awhile, and could've killed him without all the proper safety systems they had in place. We're glad to still have Adam with us alive and well. Thanks Mike for another great video! That last muzzleloader shot was devastatng!
mike, i don't know if it does anything for you, but this random old man thinks you're one of the coolest persons alive. i'd gladly carry your water just to be part of one of these crazy journeys you undertake so regularly.
I would advise you to drill a few holes at the end of your barrel in order to release the pressure that occurs in front of the projectile all along the barrel. While this has less impact on heavier projectiles, the Nerfs are light enough to be affected by this phenomenon. It is also possible (pure speculation and for blue projectiles) that this slows down the dart enough that when it comes out of the barrel, the pressure to propel it is so strong that it transforms your projectile into a balloon on the verge of exploding since it is no longer supported by the walls of the barrel. Holes at the end of the barrel could release the pressure before the projectile is no longer carried by it.
You could take this project to another level with a rifled barrel. Its simple to DIY with a 3d printed jig, some copper wire and electrolysis. The 3d2a community has been doing it for years.
In slow motion you can see the biggest issue destroying the nerf darts is an overpressure as they leave the barrel. Drilling several small ports in the barrel a dart-length before the end of the muzzle could relieve the pressure before the dart exits. You'd be losing acceleration length though, so I would recommend a longer barrel if you tried this approach.
It may be even worse, on my point. The projectile is not a solid bullet. It seems like the foam is highly saturated with compressed air so it expands after leaving the barrel. It may probably happen, that the foam will partially expand in that area of pressure lowering, so it could be caught by theese drillings. It can cause the projectile destruction before it can leave the barrel...
@AliaksandrTt The holes would certainly need to be small so as not to allow the foam to expand into them. But if you can mitigate that, a release of the pressurized air before the dart meets ambient air would give the dart the best chance of surviving. Right now it's an immediate cutoff into ambient pressure and the dart is behaving like an overinflated balloon.
11:25 - Fun fact, when a bullet cants like that it's called "keyholing." In a traditional rifle it (typically) means you've shot your barrel out, but not always. Love your channel btw man. You're like a grown-up, fun version of Mark Rober. I mean, he's fun too - for kids.
imagine having a normal nerf war and then someone fires a dart into ur chest so hard it penetrates ur heart and now u have plastic sharpnel in ur body 😭
4:57 you mention that cold and humid air is more dense, but it's worth noting that humid air is actually LESS dense than dry air. Cold air is more dense than warm air, but humid air is lower density than dry air.
@franky2shoes660 that's because dry air and humid air have the same number of molecules, but humid air has part H2O molecules which are lighter than the molecules of dry air. The reason why water itself is obviously heavier than air is that it has more molecules, but that cannot happen in gas like air (at normal pressures)
The best projectile for something like this would be one that has a Diabolo shape. This shape is what the pellets in regular pellet guns use and is somewhat self stabilizing while travelling at high speed through the air. The weighted front of the projectile works in conjunction with a drag producing skirt at the rear to aid projectile stability. As long as these were made out of sufficiently dense material to keep them subsonic, as the transition from supersonic to subsonic destroys projectile stability most of the time, you should be able to hit targets at a decent range. The easier but less accurate, while still being likely your next best option, would be to just use ball rounds.
Could also try a projectile with fins on the back with a profile that is smaller than the bore). A dart type thing or even just cross sticking out the back would probably improve the performance. Although you might need a ported barrel..

idk anyhing about that but you couldve just lied to my face and i wouldve believed you

@notfullyplaced8281 there is no firing pin tho.
@FazeParticles Some countries classify anything over a certain power a "firearm". Under UK law this would definitely be a firearm, which you need a licence for. Probably similar in Italy.

I think it would be easier to shoot a lead ball, it will be more accurate and easy. Just like a shotgun shell
But there’s a reason why those are smooth bores mainly because of the ammunition.
The ammunition used these days are far quicker and reaches stabilisation due to how those are designed. Smooth bore helps it slow it down thus retaining effectiveness.
@patrickiamonfire965 I thought tank guns were smoothbore because it specifically made the darts go faster and allows them to be longer aka more effective against armor
with long rounds spin just causes tumbling, so fins are more effective for stabilization
@arctan4547 it's because of the sabots specifically. You don't want to rifle those if I remember correctly.
@arctan4547
well , APFSDS(armour piercind fin stabilised discarded sabot) its simply a metal rod encased in a sabot , it flies fast and straight and are designed to be effective against modern tank armor because speed beats armor, british tanks still use riffled barrels in their tanks. and yea, trying to design an sabot round for a bore that small , it will be pretty tricky
Finally a long range weapon that is useful in the apocalypse

But the ammo is still one time use (you will never find them)

Just a tip for the rifled bullet (from someone working in the industry and talking with many ballisticians) the reference footage of the bullet that you put into the video is 8.6 blackout, one of the fastest twist rates of any bullet manufactured today. Looking at the spirals of your printed bullet, they are WAY too steep (they have far too many rotations per inch) and you may be getting serious destabilization due to it. Try it again, but this time calculate a twist rate on the projectile for a 1:10 twist rate. (One full twist every 10 inches). Other inspiration can be had by looking up "rifles 20ga slugs" and mimicking some of the design choices.
Agreed, and even compared to the 8.6 blackout comparison in the video, the angle of the grooves on the 3D printed one looks to be ~45° or maybe more, while the 8.6BLK is maybe 10-20° on a quick glance. What he made is a screw, not a rifling. =)
....ballisticians...my new favourite word....sounds like people who design men's banana hammocks to keep things in place...how am I going to work this word into a casual conversation ? 😁
This or just a basic APFSDS round
Sound like the recipe for a clean kill but this ain't GTA 5 💀💀💀
I think 1:10 is still to agressive maybe 1:12 or so that would still stabilize the round while not fouling the barrel
Isn't that just a sniper now? 💀💀
Fr tho
Well in like 100-300?metirs ish (idk) it prob is but its most likley very innacuraye after that
A sniper is a person who has a rifle aka= recon
I dont understand
@Kebabrulle-j3qhes talking abt the sniper rifle
You just reinvented the Girandoni Air rifle carried on the Lewis and Clark expedition. Some were used as sniper rifles. Invented in 1779 by an Italian.
That one had a 26 round detachable magazine.
An "assault weapon" made when the founding fathers were alive
Thomas Jefferson bought one for the Lewis and Clark expedition
No such thing an an assualt weapon. Stop being a sheep.@zm1786
Nah it was Him , He just reincarnated .
Nice
Out of curiosity, how was it powered? They didn't have air cylinders at the time.
I think the best projectile to use would be metal balls like in old flintlock guns, rotation wouldn't be a problem and you could get a better seal by rapping the projectile in paper like they did as well.
I know it's not as cool as over engineered bullet designs with fins and all, but most of the time simplicity is pretty effective.
There is a reason for most of the commercially available air guns to shoot spheres.
yeah but the reason they're round is because sharp ones can kill
@PapaDidi-k8j well, as I said there are many real guns that uses round bullets. Sharpness can help with penetration if you can get it to fly reliably straight, but as you can see in the video, what makes the big difference is mass.
What makes airguns less lethal is mostly the lesser force generated, due to a lighter projectile and lesser pressure of the co2 cartridge. The shape of the projectile is such a small factor in comparison.
Also it is easier to feed round bullets to a chamber because orientation doesn't matter.
Yes, a lead round ball would be better, but they still suffer a lot without any rotation. They are wrapped in lubed cloth, not paper though.
@D_Boone you're right they used cloth with flintlocks, paper was used later with old revolvers like the Lemat and Colt navy before bullet casings were a thing. I mixed it up by mistake 😅
And yeah, rotation would still help with getting a more stable and straight trajectory. When I said rotation I meant misalignment, if the round rotated out of alignment it would't be an issue because there is no tip in the bullet.
@Zx_Z3r0 Well another alternitve would be a minae ball. With its hollow base there might be enough pressure to cause it to expand out giving a better seal. Also it has the benefit of being lighter in the rear and heavier at the nose which would also help some with stability. Ultimately without rifling stability is aalways going to be an issue for any lead bullet without the exception of lead balls. He also could try elctro etching with saltwater and a battery in the last 4 to 6 inches of the barrel creating starline choke. This is more common in countries like russia where its easier to get a "shotgun" than a rifle.
17:25 you can see immediately that he's beginning to fear what he's made lmao
"Oh my god I posted instructions on how to make this thing on the internet anyone could have one what have I done" type look
"And now I'm become death" ahh moment
@stickguy9109 my exact thought
that was gold ahahaha
Yeah, if they don't make this in the first place, someone else is gonna make this. Especially if you don't get detected with real ammo and real sniper. Because they can create it by themselves if you are experts crafter
I wholeheartedly beleive this qualifies as an unregistered firearm.
13:40 "FATALITY" ahh moment 💀

"SIR YOU CRACKED 8 KIDS SKULLS OPEN
Pretty cool. When I was a firefighter, we discovered that the end of a 3/8 inch length of white pvc pipe fit exactly onto the threaded end of a 2,200lb pressure air pack tank. We used to make darts out of 10 penny 2 3/4 inch framing nails with paper cups and duct tape. One guy would aim the open end of the pipe, and the other would crack open the valve. It could shoot that dart clean through the doors of a junk car we used to practice auto extraction on 20 feet away.
Just firefighter things. I swear, you guys are pure chaos.
Sounds like y'all needed an arsonist in town
@no1DdC I mean, they do run into burning buildings for a living. Being a little insane is basically a requirement
17:41 "It is so intact, hardly deformed"
while looking at the skull getting fucking obilirated
Talking about bullet
@E-WasteGamer yeah thats what he meant, but...
I think a ported barrel might fix your darts blowing apart. There is a cavity in the dart that is pressurized in the barrel, but the dart is supported on the outside by the barrel. Once the front of the dart exits the barrel, it is no longer supported but still has that pressure inside until the back of the bullet exits the barrel, releasing this pressure. A ported barrel would release this pressure while the dart is still supported by the barrel, possibly keeping the dart together.
Wow, I was thinking that about the inside of the dart being pressurized as it came out, but I didn’t think of a ported barrel helping.
I’m glad you saw that too hopefully he sees ur comment i was thinking he should fill the hole since he doesn’t need it and hopefully that will stop that
Wouldn't reinforcing the dart be an easier solution? Say, did it in epoxy or resin or give it a single fiberglass layer shell?
@jaredfritsch6833depends on how many times you plan on firing it, because it’s not like you’d be able to just reuse the reinforced darts due to being flung into objects at excessively high speeds
@jaredfritsch6833 yes, but I was trying to come up with something that kept the stock unmodified. So, all things being equal the dart being fired is identical to one you ahoot from the toy.
The longer barrel allows more time for the darts to accelerate, so that is actually a huge impact. Also kinda interesting that you still got it to supersonic despite a shorter barrel.
18:54 yea no one is surviving that😂
like if any other person would survive the last 3 darts, you brain would fucking explode
I think you'll be able to walk away from that..
@CP9773West My brother in Christ unless you are wolverine or Deadpool you are not walking away from that
I probably could
@Knight_Night25After watching 3 years of Ukraine war videos I have learned the human body is FAR more resilient than you think. People survive stuff you wouldn't ever think possible. I've seen people survive multiple grenade blasts from drones right by them. The mortality rate of gunshot wounds to the head is around 93% but people do survive shots like these from time to time.
The speed is literally mind blowing!

BRO WHY THE FUCK IS YOUR PFP THE SAME WITH EVERYONE ITS SO CRINGE
2:10 ahhh METRO EXODUS memories
So I just watched this, and remembered a similar video TheBackyardScientist made back in 2018, where he actually explained the reason the nerf darts destroy themselves when shot with high pressure air. Essentially, instead of pushing only on the back of the dart, the air enters the center hole that's used to center the darts in a nerf blaster, and then expands extremely quickly, which shreds the darts, and is also why the head of the half-length dart flew off. The way to solve it is actually pretty simple, just plug the hole with something like an ear plug, which prevents the air from getting inside the dart and tearing it apart.
Yeah! I mentioned that video in the part 1. We tried using an earplug and the dart didn’t break, but the speed was also lower compared to not having it
Hiiii
lol what? We literally proved a dart went supersonic. I just said with an earplug the dart was flying slower. Chronographs are much less accurate than the distance/time method
@meikgeik That's not what they said. They said they tried but that it caused slower speed. If you use logic you can realize that they did not add that attempt because they already verified that it was not beneficial.
In a project you always show the tests that work, not necessarily you show bugs or tests that you consider unnecessary
Hi
9:18 it ignited!!!
Thx
I think that’s just a reflection.
saw it to❤😂
Friction
The editor put “ignition” for like one frame lol
For a point of comparison, a 22 Long Rifle cartridge has about 160 to 170 joules of energy as it leaves the barrel. Although not recommended for combat/defense, a 22 LR _will_ kill. This gizmo you've created is no joke.
And it doesn't always do a sonic boom (at least in those atmospheric conditions) so it's a bit "stealthier" than a .22 LR on those hunting trips.
@andrewg7576When i shoot subsonics from my suppressed 10/22, the only sound you hear is the cycling of the action. It is insanely quiet.
13:46 was exactly like a sniper elite kill cam 😂
EXACTLY WHAT I THOUGHT
==UPGRADE TIP==
you need to use a faster opening valve like a solenoid to help actuate the primary qev faster. Also consider using a smaller secondary QEV between the primary and the pilot trigger at least for faster actuation = more power
Solenoids usually have very small holes inside and I'm pretty sure he already tried it in previous video.
The actual best valve for this is a burst disk
@linecraftman3907 burst disc indeed. Good call.
@linecraftman3907 It's been a while since I watched his original video, but I think the solenoid released air too rapidly and caused the darts to disintegrate inside the barrel, so he switched to this. Might have worked better for these lead projectiles though.
The real problem is that compressed air at room temperature travels at the speed of sound at room temperature. To exceed the speed of sound, you have to use hot air.
@amosbackstrom5366 not really
you need a delaval nozzle
Rifling is dependent on weight and speed of the projectile to create stabilization of the projectile. In same, weight, design and balance of a technical pellet also creates stabilization. The lead loads would have stabilized with more FPS, a marble would have been a great projectile to test here as it has less limitations to these effects.
9/10, because your curiosity makes fantastic content in itself, with your voice selling it without doubt! Fact alone you did not stop to get that supersonic Nerf Dart is a huge win!
Hey mike i have a suggestion that would make your device much more powerful without any changes on the hardware.
First a bit of theory to explain my suggestion:
A gas under pressure can only expand at the speed of sound in said gas. If pressure increases beyond the point the gas can move away from the point of high pressure, so if it still tries pushing away beyond the gas front reaching the speed of sound, the gas just bunches up on the gas front and creates what we know as a shock wave. If we use air under pressure to accelerate our projectile the theoretical maximum velocity of the dart can not be more than the speed of sound. If the dart is traveling at the speed of sound the gas behind the dart pushing it forward can not move any faster itself. Even with a million psi behind it it would not go faster than the speed of sound.
Now my suggestion:
You could use a gas that has a higher specific speed of sound. Helium for example is not too expensive, available for purchase to anyone and the speed of sound in it at normal temperatures is a whopping 3500 km/h! Which would be your new theoretical maximum speed for the projectile.
You could also heat the gas you are using, because the speed of sound of a gas increases with temperature.
Thats how regular firearms do it. The chemical reaction of the propellants release mainly CO2 which then pushes the projectile through the barrel. But CO2 has a speed of sound very similar to air, so why are firearm projectiles so fast? Its because the CO2 leaves the chemical reaction very very hot which increases its speed of sound dramatically and makes firearm projectile speeds possible.
Be careful with heating pressure vassals though, because increasing the temperature both increases the pressure and lowers the tensile strength of the material the vassal is made of. So, dont blow yourself up and use warm helium and a long barrel to reach crazy speeds. For the maximum possible pull a vacuum in the barrel, so the dart doesnt have to push away the air in front of it when traveling down the barrel.
To recap: Use Helium to pressure the tank. Make sure the gas isnt cold. Use a long barrel. Pull a vacuum on the barrel if you can. Do this and you should reach projectile speeds around 970 m/s.
Bro is cooking with this one
NASA uses air guns to test material strength and impact dynamics using just regular air mix . They use up to 20k psi and a vacuum pulled on the barrell to enable rapid expansion of the gas. Using these methods, they can get a 3mm steel BB up to Mach 7.
I disagree with your statement about not being able to use air. Here is my explanation.
This is a pretty basic fluid dynamics system, we have a pressure chamber with an outlet. With the barrel acting as a simple nozzle, the fluid (and therefore projectile) leaves the barrel at a lower pressure but higher velocity. So if our goal is to have exit velocity greater than the speed of sound you will need a supersonic nozzle to accelerate that fluid past that point.
These convergent divergent nozzles are how rocket engines work, it just takes a lot of energy to get the fluid up to those velocities (but in your example a MilLioN pSi cOulDNt bReAK thE sOuNd BArriEr) I’m just poking fun at it, but seriously we have been expanding gas across nozzles for a while and is always the solution for increasing velocity.
What are you talking about with "pulling a vacuum"? You do not want a sealed system in any projectile-firing device like this in FRONT of such pressures. Unless you literally mean putting a vacuum machine's nozzle to near the barrel, creating positive pressure in front. Not literally a vacuum, though. I should look this up.
@adamsazaquatics3079 a gas can be accelerated to supersonic speeds, but it will not expand at super sonic speeds by itself without trickery.
Supersonic nozzels perform very bad against backpressure. If the gas cant freely or relatively freely leave the nozzel, but instead runs into a barrel blocked by a projectile which creates high static pressure behind the nozzel it will not work as intended and instead effectively only reduce flow rate.
In theory you could have a very long barrel and slowly approach the projectile to speeds at which the gas can leave the nozzel with less backpressure building up at which point it would function normal again and push the projectile at supersonic speeds. But my guess is that the barrel would need to be so long that the barrel walls would provide enough friction to the gas along its path down the barrel to the projectile that it would shlow the gas down significantly. In other words, i dont think that would work at all.
And of course that would require very precise and expensive nozzels and other hardware to make the super sonic gas flow a reality.
Instead he could just put helium in his existing machine and achieve supersonic speeds. Low cost and effort.
Kind of ironic that you laugh at my proposal and then propose a complicated, expensive and likely not functional alternative.
man, wrapping it with tape really kept that dart together, i wonder what the speed of THAT was
I'm remembering why the pneumatic rifle and pneumatic crossbow are my favorite weapons in Metro... No significant sound, head explosion. A stealth dream. Conquering Pripyat with a nerf rifle.
That ball bearing rifle carried me through so much of the game.
i loved that gun too
Eye roll , while no hearing protection is needed, I have a PCP rifle, it is really loud. No stealth in real life with big bore weapons without a real suppressor.
Yo what how did i never seen pneumatic crossbow ? What Metro game was that ?
The whistling air sound after it shot feels like a last breath taken, the kind of terrifying sound that sticks with you.
The Death Rattle!
18:54-18:57 that's so cool. The bullet went in perfectly straight forward and seemed to come out the other side completely flipped around. The extra damage the projectile would do while spinning inside adds ever more carnage.
the extra damage wont matter lol, Thats a whole kill shot😂
Nice eye
Not only that, the penetrative power was so strong, it didn't push the dummy head off the table like the other ones, just went through like a knife through butter.
17:25 the way bro rubbed his crani after seeing the damage😂😂 bros glad it ain’t his head
*_Some truly epic high speed footage! Great work guys!_*
_Maaaan, if that thing had an actual rifled barrel.. it would be nutz!_
Rifling would surely rip the dart to shreds😢
The most tank barrels are smoothbore. Battleship guns would of been made smooth bore if made nowadays
@gerogyzurkov2259 but don't the things that those shoot blow up?
@deathlordicelord8402 Yeah because tey are expensive
@deathlordicelord8402 no not tanks anymore, they shoot an APFSDS (armour piercing fin stabilised discarding sabot) round that doesn't explode, just tears through the tank and fragments
16:54 Danganronpa ahh blood
I think the hose between the small tank and QEV is what gave you supersonic darts. That extra distance gives the dart time to speed up without just ripping it in half, and makes it able to reach higher speed. That's my theory, anyway.
Imagine being a thief and trying to rob this guy's house.

Not really, he wanted to measure speed, and these guys can help him
I would advise you to drill a few holes at the end of your barrel in order to release the pressure that occurs in front of the projectile all along the barrel. While this has less impact on heavier projectiles, the Nerfs are light enough to be affected by this phenomenon.
It is also possible (pure speculation and for blue projectiles) that this slows down the dart enough that when it comes out of the barrel, the pressure to propel it is so strong that it transforms your projectile into a balloon on the verge of exploding since it is no longer supported by the walls of the barrel. Holes at the end of the barrel could release the pressure before the projectile is no longer carried by it.
The government is threatening him because of the discovery.

9:06 "...substance similar to my salty shoe"
You could take this project to another level with a rifled barrel. Its simple to DIY with a 3d printed jig, some copper wire and electrolysis. The 3d2a community has been doing it for years.
In slow motion you can see the biggest issue destroying the nerf darts is an overpressure as they leave the barrel. Drilling several small ports in the barrel a dart-length before the end of the muzzle could relieve the pressure before the dart exits. You'd be losing acceleration length though, so I would recommend a longer barrel if you tried this approach.
It may be even worse, on my point.
The projectile is not a solid bullet. It seems like the foam is highly saturated with compressed air so it expands after leaving the barrel.
It may probably happen, that the foam will partially expand in that area of pressure lowering, so it could be caught by theese drillings. It can cause the projectile destruction before it can leave the barrel...
@AliaksandrTt The holes would certainly need to be small so as not to allow the foam to expand into them. But if you can mitigate that, a release of the pressurized air before the dart meets ambient air would give the dart the best chance of surviving. Right now it's an immediate cutoff into ambient pressure and the dart is behaving like an overinflated balloon.

All the assassins will be throwing away their guns and using pipes & air pressure.
Ngl I think making a simple trigger system and putting it in a homemade 410 is much easier than uh y'know making an airgun
call somebody from jackass to get shot by it with a nerf dart
11:25 - Fun fact, when a bullet cants like that it's called "keyholing." In a traditional rifle it (typically) means you've shot your barrel out, but not always.
Love your channel btw man. You're like a grown-up, fun version of Mark Rober. I mean, he's fun too - for kids.

I was waiting for this video so long. This is top content
14:01 was that the shot of 97 😲
PoV: at 18:46 is when you take a ride in your convertible in Dealey Plaza in Down Town Austin, Texas on Friday November 22nd 1963.
4:57 you mention that cold and humid air is more dense, but it's worth noting that humid air is actually LESS dense than dry air. Cold air is more dense than warm air, but humid air is lower density than dry air.
Oh cool
Okay
How so, when now you have more water particles in the mix?
@franky2shoes660 that's because dry air and humid air have the same number of molecules, but humid air has part H2O molecules which are lighter than the molecules of dry air. The reason why water itself is obviously heavier than air is that it has more molecules, but that cannot happen in gas like air (at normal pressures)
The best projectile for something like this would be one that has a Diabolo shape. This shape is what the pellets in regular pellet guns use and is somewhat self stabilizing while travelling at high speed through the air. The weighted front of the projectile works in conjunction with a drag producing skirt at the rear to aid projectile stability. As long as these were made out of sufficiently dense material to keep them subsonic, as the transition from supersonic to subsonic destroys projectile stability most of the time, you should be able to hit targets at a decent range. The easier but less accurate, while still being likely your next best option, would be to just use ball rounds.
Could also try a projectile with fins on the back with a profile that is smaller than the bore).
A dart type thing or even just cross sticking out the back would probably improve the performance.
Although you might need a ported barrel..
