No one uses cards anymore. You scan them in and add them to your smartphone. So no one believes you like it. Surely you use those types of apps aswell for any loyalty card. And you aint got that many other card. So
THANK YOU for addressing the safety in an interesting way!
When the two bullets perfectly hit each other it looks like your shot a single bullet into the worlds strongest mirror. Insane.
when an unstoppable force meets an unstoppable force.
now we also need an immovable object to meet an immovable object.
or like having an impenetrable piece of glass seperating both.
It just levitated and rethought it's place in space and time
I commented years ago challenging you guys (collective youtube makers) try to make an anti sniper shield using high speed cameras, or however might be possible
Now make a robot do it.
16:24 first colision between them (not perfectly hit)
18:51 perfect shot
26:36 another great shot
Thank you for that.
Thank you! I came to the comments looking for the timestamp 👍🏻
21:52 perfect shot, stopping both bullets at point of impact. Truly impressive!
20:24 is so awesome, too, and 20:46 as well
The destroyer of lengthily documentaries! We salute you 😂
A buddy of mine who used to go metal detecting for Civil War Artifacts, once dug up a perfect specimen of two mini-balls that had hit HEAD ON and fused together. The artifact itself was amazing, but even more amazing was to realize that because both bullets had hit each other perfectly, the two soldiers had LIVED!!! After that fateful shot, it was probably not a good outcome, but at least for that moment in time, they both lived to fight another day!
You are assuming at the same movement there were not other incoming rounds from other soldiers in play.
@@loquat44-40 No matter, the fact remains two rounds hit head on mid-flight. The two that were shooting at each other hopefully lived to fight another day...
@@chrisosti ". The two that were shooting at each other hopefully lived to fight another day.."
So you imagine they noticed that their bullets hit each other and just went "hey, that's a sign from god, we need to be friends now, everybody else stop shooting at us please."
You don't think it's more likely that they just assumed they missed and reloaded and tried again? Also, the idea of two soldiers firing at eachother is just bizar. When somebody is aiming at you, you take cover.
" that because both bullets had hit each other perfectly, the two soldiers had LIVED!!! "
You have no clue what that war was like, ammiright?
@@chrisosti ''hopefully'', I am not sure what it and good intentions are worth.
The fact that the sponsorship was the end of the story of this video is so great. That is such an amazing way to incorporate a sponsorship. Since I have UA-cam premium it tried to automatically skip it and I feel like there should be some way for UA-cam to make a distinction between actual content and just mindless sponsorships. If you have UA-cam premium rewind it to the point till before the sponsorship started and to make sure to watch it. It is so cool and you don't want to miss it.
If it weren't for this comment, I would have missed the segment cuz it skipped it for me too....

Destin, as the safety specialist at work, I would be absolutely thrilled to see a video of some of the planning and safety procedures before during and after one of these experiments!
Seeing those two bullets frozen in time in the middle of the air at 21:39 (22:00) was so amazing... It's literally forces cancelling each others out perfectly. I'm so blown away by this.
@@inoxx1151 idk but I know I wasn’t expecting two identical pieces to just be frozen there

I work in OT&E and the safety procedure evaluation towards the beginning was an unexpected but absolutely crucial component of your process. Really incredible work Destin.
Yeah from the intro I was thinking how I would attempt this, and the details they went into with the safety planning demonstrated well why I shouldn't try this at home.
Only thing missing is environmental safety. All that lead going into the ground

Thank you, godspeed! o7
The shot at 21:55 is arguably one of the coolest things that's ever been produced on the internet. I know you said you weren't trying to win the internet but that shot is in contention for it. I really appreciate you bringing all of us with you on this journey, Destin
Looked like a creation moment. Glad you put the time stamp

@@2ScoopsPlz Watch the whole video. It's worth it. It's how you get smarter every day.
I imagine this happening in a western-style duel. Both duellists shooting exactly at the same time and then wondering why apparently nothing happens :D
watching this episode for a second time after 11 months of airing. still one of the coolest episodes!
The Union and Confederate soldiers who did it on their first try without even trying: 🗿🗿
I notice that both your barrels have right hand twist, so when they are facing each other, the bullets are spinning in opposite directions. If you had one barrel with a left hand twist, both bullets would spin in the same direction. With the rotational energy cancelled out, it seems that it would be much easier for the bullets to fuse on impact.
Exactly this!!! I was looking for this comment.
that being said, if trying to recreate what battlefield example then they are doing so.
Your example wouldn’t be historically accurate.
GREAT POINT. Were the civil war rifles smoothbore?
I think part way through the war they adopted rifled firearms. While smoothbore might make the shot possible, trying to get the bullets to collide in the first place would be much harder
@@smartereveryday Most were rifles so not smoothbore.
One of the most interesting videos I have seen

This video has to be hands down one of the most well explain shown video, i have ever seen in a while...❤
I didn't stay around to watch the whole 35 minutes, but jumped forward to the exact moment. Well done to make this!
amazing video, i love destin's excitment and daves dry combacks lol
Miss your *"subscribers milestone fireworks"* videos. Would love if you do another one for good ol' times!

Cheers!
Thank you
I cant believe they made a short clip into 35 minutes... like i care that much!
Thanks for saving my time
I'd need to waste 22 minutes before seeing 2 bullets hitting each other. I understand the research and effort, but c'mon, this is just making it boring
Thanks man you’re a gentleman and a scholar
I’m so happy with the end result of everything you did to show us how 2 bullets crash against each other, I’m saving this video for later watch again
Every shot was amazing! It is magnificent to watch something so fast to hit in slow motion and see how it behaves. Such a cool video. Thank you!
When you shot those 2 together at 22:02 and they just froze in the air on the high speed, my jaw literally hung open for the duration of the shot. One of the most stunning pieces of film I've seen in a long time. Congratulations for capturing that after all the effort you put in. It's truly amazing!
Thanks for the timestamp 👌
I noticed the same thing... like the world of physics just got hacked when they just froze suspended in air like that.
Your a freaking lifesaver for the time stamp! Nobody wants to sit through a freaking 35 min video just to see 10 seconds 😒

I came here to say the same exact thing!!!
This was awesome! I’ve always wanted to see this!
Scott! When's the collab with Destin?
Same!
Collab with Smarter Every Day! The KenFolk will love it!

Definitely would want to see a collaboration between Kentucky ballistics and smarter everyday.
I never thought I would watch this video all the way upto the end. But, wow. I experienced sheer joy seeing you so happy at acheiving every next milestone in this process. It was beautiful. I could feel your happiness.
Really enjoyed watching this, great job!! My mind however just cannot dismiss the thought that two young soldiers managed to do this using a couple rifles braced against their shoulders without any rests, without thousands of hours of preparation and planning, just raised their rifles and shot two bullets that perfectly met each other in the air melting into each other, and by the way saving two lives simultaneously! Oh the glorious synchronicity of it all! Did they survive the war? Are their descendants out there in the world living among us because of this one happening?
That perfect collision where they just froze in the middle might be the single greatest piece of slow motion footage I have ever seen in my life... It was so still it didn't even look real, that was absolutely amazing... The one at the end with the aluminum wallet was pretty cool too...

What a great video and narrative! As an 80 year old physicist with a lifelong interest in ballistics, I have a couple of comments; The muzzle loading rifles of civil war era used a much different rifling twist than modern ammunition. The use of hollow base or "mini Ball" bullets rammed down a bore require a much different idea for stabilization. The lead composition is very, very soft so that the hollow base can expand to fit the bore tightly and engage the rifling without causing so much loading drag. Many of the muskets used in civil war time were smooth bore, without any rifling. Stabilizing the bullets in a smooth bore required a round ball , or in later years a Mini Ball with a hollow base or skirt. Modern air rifles also achieve stabilization partly through the skirt stabilization. If you compute the total energy of a bullet, it is not just "1/2 mv squared" of linear energy, but has a rather large rotational energy due to the rifling twist. In a head on collision, this rotational energy is in opposition for the two bullets, To achieve true linear energy transfer, you would either have to have the two bullets rotating in opposite vector direction, or not rotating at all. For reference, a 45 colt is commonly rifled at a 1 turn every 16 inches, wheras the muzzle loading rifles ranged from smooth bore (no twist) to 1 turn every 5 to 10 feet. My suggestion is to change the rifling to very long twist, in opposition, and use a pure lead bullet if you really want to see a fused bullet. The other factor is velocity. Black powder muskets had a typical velocity of 900 to 1000 feet per second, with a low ballistic coefficient, so they would slow down rapidly. If there were something like 400 yards between the opposing battle lines, the bullets would have been traveling less than half the muzzle velocity at center path collision. You might try to fire a pure lead bullet at a steel plate and determine the amount of deformation of that bullet then take half the linear energy backed out to velocity as a starting point for your powder charge and velocity starting point. Modern large bore pneumatic or air rifles might be an easier and more controllable medium to base your configuration on.
Again i want to emphasize what a marvelous presentation you have made!!!
This is awesome info. Lots of different factors that have to end up absolutely perfect. It is possible! Who knew I'd be getting an education on youtube comments!
Ok chat GPT.
Terrific comment, love the detailed info.

Awesome!
I'm impressed with the amount of detailed work you guys did in advance. That is a lot of detailed work!
Hey destin just dropping some love. Thanks for your videos, your exitement upon creating them, and also, the great music! Keep up the great learning experiences!
The collision at 20:31 is so perfect that words cannot describe it. Great job. For science!
👍
Thank you 🍻
@@shitpostmalone5341 the hit at 22:20 is like 1 in a billion I'd say. The perfect transfer of equal kinetic energy head to head (perfectly colliding in a balanced manner with equal kinetic energy and exactly in a straight line) indeed produces phase cancelation. It is mind boggling to see this with guns. It's like balancing very powerful magnets ontop of each-other without locking them together, or balancing a camel on a🕯on a needle on a stainless steel ball bearing 🤔 on.... a match... on a fire 🔥... like, it's so hard that you'll always just burn the stuff on accident and make the camel angry unnecessarily. 😠 Ballanced forces produce stillness and static pressure fields.
Thank you so annoying lookin through long video for 5 sec clip
THANK YOU SO MUCH
If you're ever passing through Nebraska, stop by the Edgerton museum (for those who don't know, Doc Edgerton played a key role in developing the camera tech which made it possible to photograph bullets in flight). Congrats on getting two bullets to hit, though. Even Doc Edgerton didn't figure that one out!
When I completed my Master's Degree, Doctor Robert Frederick from UAH handed me an autographed book from Edgerton. One of the most thoughtful gifts I've ever received. Edgerton inspired me.

I really didn't think i was going to watch this entire video but man you kept me intrigued...great job, fantastic video.
Considering how hard this is to recreate, it is literally miraculous that these civil war bullets not only melted together perfectly, but that they ever lined up in the first place..then, to add to the miracle, some guy like me with a metal detector found it 150 years later!!
Those bullets stopping mid air is one of the coolest things I've ever seen, and definitely the most awesome demonstration of conservation of momentum I've ever seen. Wow.
The same phenomenon was captured on super high speed film 60 years ago, just fyi.

24:40 - I love that you puzzled the delaminated metal scraps back together!
Loved your colliding bullet video. A roommate and I were at his home while in college in the mid 1960 s shooting apples out of a tree with over a mile of open field behind it on a solid overcast day with a 22 rimfire rifle and I could see the bullet as it was going up. Of course in those days my eyes were like telescopes and microscopes.
Any other channel doing these kinds of videos, I normally just skip right to the money shot. But something about your editing style, the pacing, the information you share, the process of designing and building your experiments, it really is enthralling. Gotta watch the whole video!
same. i thought "35 minutes? thats too much, im not watching all of it." but then once i started, i just kept watching every second, and was like "its over already??" at the end.
@@502deth didn't even notice 35 minutes
Came close to skipping forward, but.... as you say its always watching the whole thing, glad I did.
100%
Love the engineering that went into this! The fact that so much thought went into replicating what happened in real life speaks to the massive improbability of it happening at all. I imagine each of the soldiers would have been astounded that neither got hit after quite literally shooting the barrel of their gun directly down the barrel of the other.
I wonder if the temperature of the bullets at contact have anything to do with it. I can imagine the two soldiers who fired at each other may have been firing a lot already by the time they engaged each other. Perhaps their barrels were already hot, adding some heat to the rounds before they were fired, and maybe that helped them fuse together easier?
So this is what happens when an unstoppable force meets an immovable object
Just wanna say how wonderful the subtitles are.
Not only correctly subtitling but also adding information for tone or silences.
It's always a pleasure to see them be as high-quality as they are here

This brought back so many memories from mythbusters. Those are the best high speed shots I've seen in ten years. Absolutely fantastic job from start to finish.
I was thinking exactly the same thing, bullet fired v bullet dropped came to mind first.
I heard his whole explanation of the problems on Adams voice...
what high speed shot did you see ten years ago
@peterheinzo515 look up high-speed shots from mythbusters, and you'll know they are really good
Haha definitely thought i was listening to Adam a couple times. Its more like what shot didn't I see ten years ago. Mythbusters did almost everything you could imagine on high speed camera.
Congratulations to Allan involved. Super nice video! Thank you!
loved the part about the safety measures! obviously because they keep you alive! but also because of the way you approach it! great role model for stuff like this!
The fact that you didn't just stop after the first time because it "worked" and you had viral footage and just kept doing it over and over to pin down all the variables and learn exactly what was going on is what puts this project on such a high level not to mention the many many hours of prep and planning that went into this.
Really love what you do, your passion and excitement shine through and build upon the work you clearly take seriously, thank you.
Your comment is basically what I wanted to say… As a former Naval Officer (Suitland), they were not only diligent in their work, they refined their test for precision (while being as safe as possible…
This should be shown in every physics, Dynamics, engineering class. That perfect stop shot is amazing. (Start around 21:30)
Us fellow engineers are loving this stuff.
Thanks man
This is how our ideal physics conditions are meant to play out in highschool...
I love how he has a section about safety and to do everything step by step. Sure, it's a simple test, and every single threat is small on its own, but there are a lot of small potential things that can go wrong. So he does a checklist, so nobody misses anything. They made their own protocols to follow. Compare that to the handling of the ocean gate submersible. He cared more about the safety in this test than they did for ocean gate. And we have ocean gate ceo bragging about how they didn't need to use safety protocols.
Well they really didn't stop, just slowed down enough for us to perceive it as stopping. Ok ok they stopped.
Thank you for this bookmark
This is the first video of yours that I have watched, and I absolutely loved it!
I wish you had fully played out your hypotheses about metal composition and speed, though, to see if you could actually replicate the fusion.
The distance between the ogee(the spot on the projectile that touches the lands) and the Lands( the very beginning of the rifling) effects the accuracy greatly.
I mean, the hit around 22:19 is ... probably one of the most amazing things I've seen on YT. Bonkers how something so destructive can turn into something that beautiful. Stunning. Destin and team, you win.
Thanks 🙇🏾

@@snowflake_46 shush bro u have no life
It's pretty odd to me that they actually ignored safety by loading the guns in position where potential misfire (gun firing unexpectedly) could shoot through the open hole...
Like yeah, noone should stand on the opposite side when it's being loaded, but that doesn't mean the shield should be off.
@@shinobuoshino5066 It's actually safer, if the firearm discharged while the shield was in place, the fragments would ricochet endangering the person loading/unloading the firearm.
@@yzzcat7824 common sense is not common at all these days.
21:55 I think about this shot a lot. One of the coolest visuals of physics I’ve ever seen
Regarding the straight lead bullets, it may be worth trying to remove the oxide layer. When the original fusion occurred in the civil war the bullets may have been freshly cast and easier to fuse at lower temperatures. I see this akin to soldering PCBAs where older solder is resistant to melt initially from oxides and a touch of new solder/flux enables it to melt much easier.
I think the temperature and shape are the keys - the black powder burns a lot slower and the minie ball is hollow at the back. This means a LOT more time in the long barrel and a lot more surface area to heat. The bullets would have been VASTLY hotter.
It also means very little mass at the back of the bullet to continue pushing them together after the initial impact.
Was thinking the same thing. I bet polishing and then stripping off any polishing compound with solvents would help significantly
Get the lead a pure as possible.
And then anneal the bullets after casting them.
That will make the bullets as soft and malleable as possible.
Or maybe use gold.
Maybe paint a little bit of liquid flux on the tips of both bullets. The heat of impact might be enough to activate the dried flux on impact.
I think you have a to small amount of led for them to fuse together. Bullets today is made to fly as fare and fast as possible. Thinkg they couldn do so much in the old days. So some more soft lead and a bit larger amount of it and you can do it.
This was so cool. Thank you for making this happen
Great planning, safety precautions and execution but excellent enthusiasm!

The Safety procedures is great to see.

@@TomVanWaeit's also unloaded, which he KNOWS for a fact, because he's holding the cartridge.

but my biggest takeaway is Destin's genuine & passionate excitement glowing throughout the entire video.
this is just plain fun to watch
All the safety procedures were just as interesting almost. Great vid

@@MohPlusIt's insane how good google translation has become recently. Now I can read arabic texts, pretty awesome.
Its always fun to listen to your amazing analysis ! Thank you
It would have looked visually more pleasing if the two bullets were painted in Red and Blue, and as the 2 lead merges we could see some interesting pattern and confluence of those 2 lead
Im not sure what else you do or what your channel has on it but im subscribing for this video alone. Awesome stuff, not mention the presentation.
Not sure if you thought about it, but the rotation due to rifling causes the 2 bullets to spin in opposite directions. Maybe the old bullets didn't have rifling, or rifling wasn't standardized and they both ended up spinning the same direction. This would be much more conducive to bonding.
They had rifling back then, but it wasn’t omnipresent. I don’t know if it was consistent. Good observation
This. Great observation!
Especially in the early civil war both sides did still issue some smoothbore (non-rifled) muskets, which would have been firing large spherical balls; for example the .69 caliber Springfield Model 1842, which saw service in the war, fired a solid lead ball of .675 inch diameter; weighing about 30 grams. Or about twice as much lead as the bullets Destin was using.
More lead, without opposing rotations, might be enough to make them fuse, especially if it was also a slower collision than Destin's (and given how quickly smoothbore balls lose velocity compared to spin stabilized bullets it might well be a slower collision than even low powder close-range firing can provide).
^^^this.
I came to the comments to post this. See if you can get a mirror identical barrel with a left hand twist, or two smooth bores.
You forgot to mention the speed of the projectiles… In my opinion, that is why some of the shots just essentially exploded… That is, the force of the projectiles was relevant to the experiment…
Edit: At around 26:00 they made adjustments to the powder, thus the speed, to address exactly what I was speaking about… These guys are amazing! While I understand physics, machine a lot of my own parts, and design controls using various systems (ESP32, RP2040) I am don’t think I could recreate what they did without a team like they had!
22:03 the way they came to an absolute dead freeze for a moment is absolutely insane… possible since they have almost exactly the same energy… wow it’s like the middle pauses while the rest is still in play
It straight up looks CGI. I'm not saying it was at all, it's just so uncanny to see it actually happen that it feels "off."
They needed to have almost the exact same velocity and weight!!
That's what physics says should happen, but they actually did it, on video. Equal energy from opposite directions and the main pieces just froze in place with zero velocity. That moment is totally poster worthy.
yeah its underrated. better than fusing them IMO.
I just wanna mention I do the same thing, “I felt it” “I can feel those pieces behind me”. For me I get this tingle in my ear and on what piece of body that was closest to that sound. (example, my arm would tingle when I hear my dog bark near me. This feeling is not like wind but as if my nerves fired.
Dance of the bullets - Beautiful and Deadly
It’s amazing to think that those soldiers were probably shooting at each other at the EXACT same time, and likely saved each other’s lives!
I’ve always wanted to re-create this phenomenon, thanks for doing it!!
Except.....
There probably was a follow up shot...
I find it more interesting that because the loads for each shot would be inconsistent, they didn't shoot at the exact same time, but at just the right time for it to happen. Like doing two things at the same time is cool, but having the exact right amount of delay is cooler.
It's very likely they didn't save each other's life. They likely shot each other on the follow up shot or by someone else
@@lukesfxwhen you have hundreds of dudes standing in an open field facing off in a firing line, you'll get this happening eventually for sure. The crazy part is they were able to find the lead balls after it happened.
Yeah except on a civil war battlefield soldiers were usually ordered to fire in volleys. With large units of men trading volleys this probably happened more than a few times. It may have stopped those particular bullets but I doubt it kept them out of danger for long.
"Get smart people in your life who love you enough to smile and tell you you're wrong." Great comment! Great video! Thanks, Destin. You do a great job of educating in an engaging and delightful way.
That's much harder to accomplish than Destin makes it sound.
Stopping/pausing in mid-air, that was amazing!
Those bullets stopping was absolutely incredible.
I audibly "Wow!"ed at 22:02. Getting to see how physics works through slow motion is awe inspiring. Thank you for your incredible work in getting this footage and sharing it with us!
thanks for the timestamp
It was like time stopped for that tiny part of the universe where those bullets met.
If you watched Mythbusters, they did the conservation of momentum trick where the truck moves one way while a ball is shot in the opposite direction at an equal but opposite velocity to the truck, and managed to get a shot where the ball literally did not move horizontally at all before dropping vertically.
This is literally on the same level of physics demonstration awesomeness.
thank you for not having to watch that whole 20 minutes
Energy in that shot is insane.
The image that I have always found incredible is that of the two rifle bullets from the Battle of Gallipoli.
One hit the other at 90 degrees: if the probability of two bullets hitting each other face to face is infinitesimal, hitting each other with perpendicular trajectories is really bordering on nothing.
PS: maybe the next project for SmarterEveryDay?
I had to find that pic once I saw your comment.
I can't post links because youtube is run by the guys Orwell warned us about.
So google "Reddit Two collided bullets from the Battle of Gallipoli, 1915-1916" to find the pic.
But then I saw it wasn't actually real.
Google: "lead stories Fact Check: Viral Image Does NOT Show Two Bullets That 'Collided' During Battle Of Gallipoli"
first I thought he is taking about that bullet scene only...
I haven't seen any analysis on it but everytime I saw a photo of those bullets, I assumed it was far more likely one bullet hit a clip/box of bullets and got stuck in one.
But, considering the timing involved, I do think you're right about the odds of two bullets hitting with perpendicular paths being extremely low. Though, I think the odds of them fusing would be increased, as far less momentum will be transferred (assuming lower is better).
If you look closely at that picture. One bullet had rifling marks, the other does not, indicating that one was never shot. Still pretty cool non the less.
it would be easier to try and hit two arrows perpendicular.
The alignment of the flight paths is so amazing. I can’t believe the view. The explosion was a bit of a surprise since I was expecting glancing shots and I know what not. The. The several shots like two ships passing in the late afternoon.
All the footage is exciting to watch for anyone interested in flight paths and contact, marksmanship, reloading used brass for accuracy, even barrel fouling. So many things that we consider when we want to make accurate shots repeatable.
Oh, yeah, seeing the shock wave ripple through the bullet as they impact was one of the coolest things
Calculate the joules expended.
Now scale it up to larger objects like the idea of asteroid interception or when the smaller moon struck the earth ejecting our moon. This leads to so many thoughts.
15:10 That impact of the two bullets where so good to hear.
19:00 19:57 20:28 Bullet Hitting Bullet.
21:57 best one
Thanks for saving time.
Thank you
@@EmSki45 imagine not watching the whole video XD
Interesting to see this. Thanks for taking the time to figure this out and share it.
He needs to take some time to figure out declining EROEI.
Americans and their gun fetish.
Thank you for do this experiment, when I was 11 year old, so I was thought about this experiment finally after 9 years I got answer.✌️👍
Just amazing, good work guys, the bullet fusion counts in my book...
When the two bullets hit and froze in the air, I immediately got chills. This is incredible! Love your videos! Thank you for all the amazing content!
That was a Loony Toon moment. It didn’t know what hit em
They actually defeated gravity for a ms, that's crazy
@@karlbee7836 I was thinking the mass was shifting from forward motion into a spin motion so that's probably why?
Bullets HITTING Bullets in Slow Motion - THE IMPOSSIBLE SHOT - Smarter Every Day 287
Extremely difficult to achieve. So many variables to overcome, from gun precision to mass of bullet.
Have you considerd reversing the rifling on one gun so the bulits are rotationally speed matched on impact?
Was going to say this. There's quite a lot of rotational kinetic energy in exactly opposite directions-that lead is gonna splatter!
That or use smoothbore barrels, modern tolerances would make them accurate enough at that range for consistant results.
As a BSME and a "gun nut" who reloads .45 LC (and other calibers) I was smashing the thumbs up icon wishing I could give 1000 thumbs up. Great job Destin.
Great job to all involved! And to your education and work ethic!!
Destin, have you thought about contacting a material specialist to figure out the conditions needed to get the bullets to mushroom and fuse instead of crystalizing and shattering?
Need old lead, no alloying additives like antimony and calcium, all added to make the lead a harder alloy. Old lead has a lot of silver in it, along with zinc, which makes for a soft alloy that will readily bond with cold welding.
@@SeanBZA that's so cool! Any source I can learn more about this?
@@SeanBZA In addition the older bullets will definitely be going slower
Much softer lead would be a much better choice.
No you just need old bullets…. The new bullets are made with a different type of alloy you don’t need a specialist to figure that out…
I immediately love the term "intellectual humility".
I usually think of it as being dispassionate about knowledge, but I think your term describes it better.
Definitely using that term in the future.
This is the coolest thing ive seen all month.
It would be interesting to see how much ballistic gel could capture in an experiment like this. I'd love to see you do this with old mini-ball and black-powder as well.
Great Channel, btw.
Modern cast lead projectiles typically have antimony in them, which increases the "hardness" of the bullet (this makes for a better hunting bullet). You can make 100% lead projectiles using a bullet casting tool, check with some of your reloading buddies and find out who is rolling their own (so to speak). They can probably easily hook you up.
Pure lead bullets will require to clean the barrel after each shot as they will fill the rifling and lead to inconsistent ballistics.
I also wonder if the bullets would fuse better with a bigger caliber.
Last but not least, the offset of the barrels is making the fusing more difficult, but the only option to protect the guns would be for each one to shoot through the hole of a rotating disk. It’s quite difficult to synch, but a good challenge for perfectionists!
@@tde1964 you can avoid them shooting each other by a longer flight distance, allowing drop to handle the matter for you, but also increasing the precision of the build to allow much greater precision in adjusting the aim to cover the greater range.
That said, one wouldn't have to clean the barrel after each shot, but they'd need much more frequent cleaning. One can offset the higher velocity and fouling issue by using a slightly larger bore. Lower friction and cutting by the rifling, gas leakage lowering pressure and hence, velocity, downside is lower accuracy. Chroming the barrel also would lower fouling.
This exactly! Need 100 percent lead bullets for any chance of fusion. And if velocities are low enough, leading in the barrel won’t be an issue.
What is the "hardness"?
@@georgegordonbrown9522Think of it like the "brittleness" during impact. Softer bullets would be less brittle so less prone to shattering.
I would like to see infrared footage of this to see the heat generation and dissipation of the collision. Very cool stuff guys, keep it up.
AMAZING Video Footage! Congratulations on this accomplishment. It was great meeting you years ago to record the Prince Rupert's drop segment for National Geographic. Your channel and videos have come such a long way since then. All the best in the future.
This is genuinely the coolest thing ever
Destin, the equal momentum transfer shot was absolutely beautiful. Thank you for making such interesting content!
Could you try and catch the bullets in a medium just as they meet. You could try to use a slab of ballistic gel that you can cut down to vary the length, therefore controlling how much the bullets slow down before impact. It could have an added bonus of catching the fragments mid explosion like what you did with the prince ruperts drops.
BG does affect the path of the bullet. That's adding yet another level of complication on top of the existing ones. Not the right way.
@@aserta Very true! although from other videos I've seen bullets don't seem to deviate from their course too much, especially since the gel won't need to be too thick just a couple of centimetres - enough to just slow the bullets, not stop them.
I'm thinking of the fusion of the bullets that caused this project, is it possible they collided in a medium of some sort? A wooden wall, a tree, something like that? The fusion in the wallet suggests that quite loudly to me. I KNOW someone knows more than I do on this matter. Is it known where/how the original fused bullets were found?
@@MicahScottPnD pretty sure they used softer (more pure?) led back in the day and those muzzle loaders shot a lot slower than modern guns (they didn't have the tolerances to have a good seal and the black powder wwas pretty course and unrefined.). Add to that some distance and you'd have two pretty slow soft things that could merge. The odds of that happening are insanely small though...
Your theory is also a possibility but I would expect them to still be stuck inside that medium if that happened.
I want to see them hit a block of epoxy that's about 95% cured... I want to see the shockwave captured.
