i suggest making some kind of “muzzle brake” that shoots the air vertically so we can see whatever is flying better
Id laugh if they do that and the entire barrel breaks off because the air is only being directed one way
@@myfatassdick you can always radially vent.
Or just move the target back three feet
@@myfatassdick do you not understand muzzle brakes? It's 360 degrees
THEIRISHAXE did you not understand the original comment?
He said “some kind of muzzle break” because the air is getting in the way of the camera so they need to make something that would point the air away NOT in 360 degrees
He didn’t put “muzzle break” in quotations for fun
Guy at the business next door: *moves desk to other side of building*
Tenants across the lot vacate to neighboring county.
When these guys are explaining their setup it genuinely sounds as if they’re trying to convince themselves that it’s sufficient for the task at hand 😂
it is bc if that metal bullet hit them or the golf ball then they could be dead or severly injurd
@@williamrobinson8538 no they couldn't
You need discarding sabot's, make the projectile smaller and use the sabot to seal the barrel and hold the projectile. Also some fins would keep it stable, think tank not gun.
I wss thinking some wadding would go a long way. Like a musket
Fins wouldn't stabilize it that close to the muzzle. Unlike a real gun, or even most air guns, their setup is blowing air past the projectile well after if's left the barrel. It essentially has the wind at its back the whole time. A sabot probably wouldn't work for the same reason. Maybe a sabot designed to blow apart from behind. Maybe a shape that's aerodynamically stable forwards and backwards.
@@Bob5mith what about spin, will it stabilize the projectile in that environment? I'm just generally curious.
I'm thinking of something like a rugby ball with fins to spin it.
@@AlbonitumG Spin would probably help a lot. But even if they devised a way to rifle the tube, it probably wouldn't be strong enough to impart enough spin on the heavy projectile. It's not impossible but I think it would be far less practical for their shop and available resources than playing with projectile shape and novel sabots. It would be a much more serious project and wouldn't really fit this channel.
The projectile is a tight fit in the barrel, with only a couple mm around it. No space for a sabot.
Is this really Ballistic Gel? Where is the lick test?

That golf ball would have absolutely stopped a heart
If you were a baby
i think the golf ball would have broken your rib cage then the rib cage pierce your heart
@@phantz1629 exactly
The only way this would work is to sharpen the actual metal slug, instead of welding a screw onto it. The weight of the slug is spinning it midair so the heaviest part goes first.
Or lightening the slug. Maybe by milling the back of it. Kind of like Minnie bullet.
maybe make a muzzle brake for the air cannon, make that extra air go away from the projectile
I agree. Also if some kind of makeshift rifling could be implemented to add a spiral to the projectile it would penetrate better.
Is ballistic gelatin edible? Because that human body model you have looks delicious.
It is, but might make you throw up.
True
I know some are, I guess for kids, but I don’t know why you would have ballistics gel near kids
@@goldenlightning_8974 Regular ballistic gel is edible because it's made from the same stuff as jello and gummi bears. But that is synthetic ballistic gel. I'm not sure what it's made of. I would be surprised if it's toxic, but I doubt it would be considered edible.
They need to make one out of real gummies melted down so at least they can eat it afterwards.
Has anybody ever told you that the beats in between are totally fire? Big props to David Cutter Music!
1:43 now that´s content i´d subscribe for
Smashing the gel on the table is almost NSFW
nah, not really
While I'm at work during the day I can reach my hand out and feel the holes in my office drywall from my daughter and i's experimentation with our pack of OSMOs. 100% stickage. Highly recommended.
OSMO=odd shaped metal objects= 'not' batarings ; also, cut them square hips off with the guillotine!
None of these items are lick tested. How can we verify the integrity of ANY of this?
Since the air coming out of the cannon is faster than the projectile I think aerodynamically from the projectile's perspective it's actually actually flying backwards. What I'm saying is it needs spikes on both ends, and ideally symmetric as well (two cones butt to butt).
Those flat sodas also look like better ammunition than drink.
Spinning is what needed to be honest. When spiral cuts in barrels that cause bullet to spin were introduced in guns their accuracy and reach were increased tremendously.
@@yaroslavpanych2067 the most effective way for it to work would be a fin stabilized sabot design
i love how casual the atmosphere is on this channel. It's very modern in 2021 that a single even implied insult sets off a nuclear bomb (and i hate that)
It's kinda a midnight factory shift atmosphere, anything goes long as you don't fuck up to bad
man, i love these guys. These are the kinda guys i'd wanna have a beer with.
04:37 was no big deal, just looked like my torso whilst going jogging
Nice vid but Ballistics Gel isn't meant to emulate real human flesh it's to provide a baseline so you can compare bullets apples to apples
@1:15 It's hip to be square!
Calibrated Ballistic gel is not really supposed to simulate people. It's just a consistent testing media so different tests can be accurately compared.
I reckon this has to be true. Last time someone got hit with a slug like that I am sure it didn't just bounce out and roll away.
Mitchell: well that's because nobody has donated us their body yet so?
Reason why we wouldn't 1:40
"That's like 8 Inches, that's pretty good"
That's what she said.
Something strangely satisfying seeing Mitchell bouncing a ballistics gel torso around 🤔
Gave me some ideas for sure
1:04, Once I die, I donate my body to science specifically for the waterjet channel.
1:48 "so, first we will see if a golf ball wil kill a human"
depends if you chew before swallowing..
A couple of notes from someone who spent far too much of their childhood building air cannons:
Your air reservoir is FAR too big. A pneumatic cannon only really needs about a 2:1 ratio between chamber and barrel volume. After that, the performance gain gets less and less. A huge air chamber just adds more time between shots, and a big blast of air that makes it harder to film.
Secondly, a manually-actuatated ball valve is way too slow. Your projectile is gone before it's even halfway open. The best solution is a high-flow piston valve (search 'barrel-sealing piston valve).
These do take a bit of effort to build, so an easier solution is one (or more) large quick-exhaust valves. These are extremely fast-acting valves which are actuated by venting a pilot valve (such as a ball valve or solenoid valve). They're readily available and will make your cannon go 'BANG' rather than 'whoosh'.
I absolutely love the half-ass unsecured supports for the dummy and safety precautions taken with pieces of half-inch plywood, it cracks me up how everything falls from the rush of air. I hope you arent hurt at all, but it really fits your vibes xD.
The comedic timing on the "We were throwing (totally not batarang)s at this" followed by the footage and that "ploop" sound effect was masterfully done.
Awww c'mon.. Mitchell should've def been subjected to lick test the torso 😂
Try carving some deep rifling grooves in the bullet to improve stability as it goes down the barrel
Lead with hollow point in same calibre as that steel slug :) Make Mr Taofledmaus proud!
Hm, try firing a APFSDS-like thing from the cannon
if I donated my body to you guys for testing, would you put a kanye 2024 sign over my forehead??
Yes
@@JJ-ex7fw brilliant
About goddamn time! Have been wondering "where dat video at?!" All day. Thanks guys. Been looking forward to it. As I do every weekend
Run the ballistics gel torso through a two-stage snowblower
Shoot the ballistic gel with a badass looking lethal home-made arrow (or just arrowhead) that lights on fire on impact so if the shot doesn't kill, the fire will.
Look at this unrealistic square hips!
That made me laugh!
Mitchell wants his hip to be square
Put a big firecracker inside of it, and film it in slow-motion.
The point is acting like flights on an arrow. The center of mass is well behind that tip so it just acts like a weather vane at that point
The no one has donated a body to us for science joke got me
You all need a little bit of spin on that large behemoth slug
im glad to see that ballistic gel torso is branching out after he did so well on the shape of water.
1. stretch rubber over the manual valve and let it go to create a faster opening system that is still mostly manual. Joerg Sprave did it with his air cannon experiments. 2. make something that goes OVER the barrel, then you can add fletching and make it fly straight.
“Who doesn’t want square hips” 😂😂😂
I think that the problem with the "bullet" is that it's not spin stabilized, an idea can be to add elliptic grooves in the slug to make it spin using the air pressure difference
They talked about that in the video.
Perhaps adding rifling to the barrel instead?
I know, easier said than done.
@@disgruntledegghead6923 grooving a barrel is an experience... You should look at videos about that, that's fun.
* a pellet is shaped like the way it is so it flys straight if that helps*
Probably should redo the barrel, maybe incorporate one with rifling grooves instead of grooves on the bullet. Seems like it would work better if there was also some way to cut the excess airflow off so the air doesn’t disturb the ballistic once it’s out the barrel
It'd be easier and cheaper to make a sabot and add fins to the bullet.
Glass balls vs Ballistic Gel!
I miss the honk of the electric valve, though.
This may be an unpopular opinion but, I don’t care if my soft drink is cold and fuzzy or warm and smooth, as long as I can drink it I’m a happy man
Glad y’all take more safety precautions than that dude whistlin diesel
3:21 - That's a great shot. Right where the heart would be.
Try putting fletching on the bullet. You could weld a longer bolt on the back end and tack on some square sheet metal. Maybe that would give the bullet enough stability.
Ballistics gel is a good model for penetration but not for flesh damage, the gel will reform while flesh tears when stretched leaving cavity wounds from real bullets. The force of the bullet moving through you creates that cavity.
6:43 that bullet vanished like Mario jumping into a painting holy fuck
Making a converging diverging nozzle in the air stream straightens out the air and makes it go a higher velocity like pursing your lips when you blow. I bet it would make the steel shoot straighter. I made a 3d printed one that fits in a pvc union for an aircannon that helped with this.
Nothing adult-related because you two are just tall children.
If i die, i'll make sure to donate my body to you guys test the air cannon :)
That was some great Cold War product placement
Hollow out the back of the bullet about 1/4 of a inch might fire better ?
I will make a donor card saying ´Give my right hand to the waterjet chanel´ for when i die in a few years time
"Hey, let's just lean a bunch of pallets up everywhere. That way we can pick up all this crap after every shot"
Chuck that bad boy in the lathe. Make the base slightly hollow to increase velocity and move the center of mass forward of the center of pressure to make it fly straight. Then shape the front end to look like an oversized Phillips screwdriver.
Someone working nearby is gonna walk out to their car after work and find a batarang in their windshield 😂
Can we take a moment to appreciate the way he said boi at 1:30
I hereby leave my body to the WaterJet channel in the event of my early demise
This video has some strong Budget Mythbusters vibes.
Put your barrel under vacuum. Your velocity will increase a bunch
Re: 1:00
Mitchle donates his body to science one lick test at a time
Launch a can of Mountain Dew, obviousky
If you look at a shotgun slug, it often has grooves in the side towards the rear end. This is to ensure that the heaviest part is the front, which leads. It also creates turbulence and drag at the rear, further stabilizing it. This would work best with the subsonic projectile you are using. An actual shotgun slug travels above the speed of sound, so it must be shockwave stabilized or the shotgun must be rifled.
You can get away without rifling if you carve a deep, wide groove towards the blunt end of the projectile, and reduce the air capacity so you don't have a ton of extra air pushing the projectile.
Fire fruit at the gel torso
Oh! fire gummies at the gel torso.
It bounced back because the wood was too close to the dummy. It would've gone through if the block had not been behind. The piercing one isn't working because there is not enough mass in the tip. It throws the center of gravity off, which causes it to tumble
Your steel projectile need to have a hollow base inorder to fly straight. Rifled slug are not stabilized by the 'rifling' on the outside of the slug, instead they are drag stabilized by having the majority of their mass in the front with a thin lead skirt at the rear. Like a badminton.
Skiddly doo, skiddly dee!
Your body is now hollow from head to knee!
What’s the I.D. of the barrel you’re using and can I send you something to shoot from it?
i love this channel! it's just a couple of buddies who fuck around with industrial equipment!
Love the PH intro at 3:21
THIS IS ART!!!! Suggestion for the gel body: Test it under extreme g-force. Drop it from different heights. Put a nice business shirt with a tie on it. Take it to a job interview. Try to get it a girlfriend and take it out on a date. Push it down a water slide.
Look up "diablo" shaped projectiles, will keep it flying straight out of your mass accelerator lol. Also check out Taofledermaus' channel for ideas on shapes to put through that thing.
Yup, I was thinking the same thing!
"How many do you think hit it?"
"Seven..."
"There was only 3....."
if you want it to lodge in you need a design similar to self defense hollow point rounds used in hand guns, and the barrel needs to be rifled and the projectile needs to be made out of something soft like lead so that it actually collapses.
Make the bullet into an arrow, lathe down the back of the bullet to the inner diameter of 1 1\2 abs pipe. Glue this on the back about two feet of it to help the turbulence. And sharpen the tip to a really sharp cone shape so the now improved "arrow bullet" will go through the target every time. Also, try making those steel bearing bullets and try shooting several at the same time to make a shotgun. Try shooting at cinderblocks, they are my favourite target.
Remember, the center of lift should always be behind the center of mass
That man strait ate that bullet
6:42
conclusion: this bullet can teleport.
That golf ball just rebooted the ballistics gel
Make a pack of tiny steel balls and air cannon it. Like buckshot. Or red hot nickel ball it
I will donate my body to waterjet sciences when I die
air wants a point to close the airflow around the projectile thereby the flat end is more dynamic tip with the pointed tail.
If the soda doesnt have fizz normally means it's old the co2 can escape from the seems of the can. If left long enough even the water can escape from the seams.
Make a hollow point bullet for the air cannon. In theory it should expand inside of the ballistics gel and create a large wound channel if the side walls of the hollow point are thin enough.
I love the way they had to say nothing adult related, when asking veiwers for ideas on what to do with the gel body
Crazy people discover new bullet physics
Take the air out of the barrel. Use tape over the end of the barrel to create an airtight seal. Gives it much less air resistance and this much more velocity
I want to take a bite out of the ballistics gel.
What about firing a whole bullet, casing included (maybe remove primer and powder) but I've seen brands use full bullets in diagrams
The projectile inverts because in every flying object if the center of pressure is too close or even in front of the center of mass the object will invert while flying
