Its been a blast of year again with your videos!
Could you do a whip next
15:46 the superimposed video was very helpful in visualization... probably was hard to get the angle right to do that but these few seconds were very beneficial
Thanks. It was a last minute addition but I’m going to try and do that kind of thing more. Need to make an effort to get a shot with the angles perfectly matched.
I was creasing at the idea of the picture being real and they actually did one going off in someone's hands
Such a good image superimposed with the shape charge going out of what looks like Dan's hands, bravo!
@@bencutter9084 if they did.. Dan would DEFINITELY deserve new overalls.
@@theslowmoguysTrue. I always thought it goes off in the opposite direction
Gavin somewhat-nervously describing how he has to push those cameras further than he's ever before is just awe-inspiring.
Yes, that was interesting! I know that exact feeling, though I had the experience with much much more modest equipment.
I tried to photograph a DJ in a really dark surrounding. Flash photography wasn't an option, nor was a tripod. So? You pull out all the stops available! I put on the lens with the fastest f-stop I had, set that lens to wide open, I pushed the ISO sensitivity of the dSLR to as high as it could go (while accepting a heap of sensor noise) and I dropped the shutter speed as low as I dared to go while shooting hand-held.
There was nothing left on the table, I was at the very edge of what my hardware could do, but I got the shot I wanted.
dude, he adjusted a setting. That's it.
@@Zpicismrad guys watch out it's the fun police
@@Zpicismrad I can tell you've never had to do anything serious with something you've never used before.
@@Zpicismrad Adjusted it out of the zone of normal and well into the zone of "this is getting to the edge of what the camera can even do", likely into the zone of being a combination he's never even thought about using before. For all he knew at that point, it was a combination that doesn't make sense or will ruin all but very very specific shots that this isn't one of, and is only selectable because it won't damage the camera. Of course he was nervous, he can only extrapolate from experiences in less ridiculous scenarios, experience which might not be a completely reliable guide.
As a USAF EOD Tech, i show these videos to my guys for explosives effects training. Its absolutely phenomenal content.
Go look at some of the Manhattan Project x-ray high speed films of the implosion. Same basic thing, smaller distances and far more than one charge, but really educational as to what's happening when shockwaves meet and metals in different phases combine at high speed.
You can just feel the fact they are literally recording stuff for the first time in human history with massive potential discoveries but they are just treating it like a fun hobby. I absolutely love these two.
I mean it's mostly the first time that we (the general public) are seeing this (due to most people not really being interested in this sort of thing), but obviously people who are in this field have seen all of this before. It's definitely not the first time it's being recorded in human history. People in academia/ the military have much better access to explosives, conditions and camera equipment.
Still, it's cool that two relatable guys are doing these fun things and presenting them to us (the general public) to watch.
You need to read more.
This is decades old research.
@@leocurious9919 It is indeed, but It was (to me) always presented like a stream or "noodle" of melted material instead of a small tip
@@leovodica9975 Many people spread nonsense for whatever reason. However, it is indeed a "noodle", albeit solid. The tip is just the fastest part that impacts first. Think of it like a carrot.
You two are the continued legacy of Mythbusters. Educational and explosions.
I don't know how or what the subject would be but a colab with Kyle Hill would probably basically be an episode of Mythbusters.
@@johnofthenorth6653 How about getting Adam Savage in on it ;)
I said the same thing on my comment, they are the same as the golden age of Mythbusters
Goes full circle since they were mentioned in an early series myth (soda and mentos).
I actually got Mythbusters in my reccomendations with this video
Here to support Dan's neverending sensory quest to finger ballistic gel hahaha 😂 That superimposed shot of the 10 million fps over the photo of the shaped charge is gloriously helpful editing 😍
2:35 forbidden fleshlight
Don't worry he gave it a good one off camera
2:34 you know it
I like the comparison to a bullet, too. It's helpful for putting the numbers with lots of zeros behind/in front of the decimal place in to relatable context.
You know he's banged it
8:06 The childlike joy of Dan's "I wanna do it again!" comment. Priceless.
What amazes me more than the rest, oddly enough, is how at about 15:07, you can see the explosions getting pushed upwards by the shockwave that had reached the ground and come back up. Very trippy to watch.
As an astrophysicist, the footage at 13:38 immediately reminded me of 4 different phenomena:
1) Narrow bow-shocks of runaway stars through the interstellar medium like the neutron star PSR J0002+6216 that pierced supersonically through the expanding shell of a supernova.
2) The powerfull outflows of a newborn star like in HH 211 (recently imaged by the James Webb Space Telescope by the way).
3) The relativistic jets and radio lobes of an active galactic nucleus like the 3C175 quasar.
4) The D100 galaxy in the coma cluster with its ram pressure-stripped gas tail as it moves through the intracluster medium.
These are all different phenomena from the scale of single stars to whole galaxies. It looks soo similar to some of the clips shown here (just that they are happening in timescales of thousands to millions of years). Perhaps I should take notes, there might be something to learn about the cosmos from mere experiments with explosives in a mine school. And who knows, maybe astrophysical simulations of relativistic jets could be useful for people working with explosives also.
The universe is fractal in scale. You're looking at enormous things far away, they're looking at (relatively) tiny things close up. Time scales with size.
@@sireuchre That's what this sounds like to me as well. Depending on your frame of reference, all of those phenomena appear like they are streams of particles (of varying sizes) that are moving through space and colliding with other particles. Why should they not look similar to our "cameras".
Mind you, I have no prior knowledge about any of the science behind any of this :D. I am just making a guess based on the footage and the comment of mikip.
As a nerd it reminded me of Vice-Admiral Amilyn Holdo jump to hyperspace through Supreme Leader Snoke's flagship, the Supremacy, to defeat the First Order fleet in a suicide attack. ua-cam.com/video/s2hM1tyEL0U/v-deo.htmlsi=wdPvtWVWsrUkaglZ&t=89
WTH this is what happens in space during star explosion 🤯. And people study this their whole life.🤯
@@sireuchre This is a good observation. But in science you have to be careful about scale-invariance (the "fractal" nature of things you are refering to).
For example, if scale-invariance was always the rule then why gravity asembles matter in spheres in the planetary/stellar scale, discs in the galactic scale, filamentary structures in the megaparsec scale and an homogeneus foam structure in the cosmological scale? Is the same force operating on matter, and yet, suprisingly, there is a huge variety of forms at all scales.
Another example is flying. One would think that the same principles would apply to the flight of a bird and an insect, but in fact It's completely different (bees use their wings almost like if those were paddles, to move thought the same air as birds do, but due to their smaller scale the air is physically percieved as a more viscuos fluid).
Is important to know this because It is easy to jump to the conclusion that the universe is a self-similar repeating structure and say that supernova explosions are just scaled-up versions of a grande blasts. This might be true for some specific characteristics but overall is not the same at all. And the fascinating thing is that studying why scale matters and why they indeed are trully different. So when I see a video like this, I wonder about how exactly one could recognize what we are looking at without knowing where the footage came from, and with which scale of space and time are we dealing here just by the looks. If there is no way to tell the difference, then yeah this is a scale-invariant phenomena, but if there are slight hints then It is an awesome oportunity to learn about what sets astrophysical jets apart from these human-scale explosions.
The greatest-ever sci fi footage has been created, not by CGI, but by two dudes at a dirt hole in Colorado
there is alot of VFX artits that use these as refrece. this will definetly be top of the list now
probably more like 7
And $100,000 worth of equipment. Its not just two guys in a hole.
@@peachulemonColorado?m
+ alot of explosive material and im assuming few other ppl what are asseble them..
What an insane video. This is top Slow Mo Guys.
Now put a dozen of charges in a circle, all pointing toward the center.
Then put them in a circle, all facing a bit to the right of the center, to create an explosion tornado.
(an immeasurable step up from the fire tornado)
No, in a sphere of the exact diameter calculated for maximum impact at spherical dead center...
With one charge at each pole, two charges opposite each other at the equator and two charges opposite each other at 45 degrees and ALL CHARGES PERFECTLY focused at the absolute center of the sphere and timed perfectly to go off at dead center impact...
Then back off a mile or so just to be safe!
And than some Uranium 235....
That's so cool that the Colorado School Mines supported this experiment. My great-grandfather graduated from there over a century ago. One of the engineering pranks they pulled was mounting the Dean's Ford Model T on the roof of one of the buildings. He'd be fascinated by this video.
Not only was this incredibly fascinating for us, I'm almost certain that everyone at the school was thrilled to see something that most likely no other human has ever seen about a tool that they study, and practice with every day! Thank you very much, guys.
I always wonder if scientist or such ask them to see and study their footage to help them learn things about their craft?
I'm sure shape charges have been seen using high speed cameras long ago. The military had a 10,000,000 fps camera in the 1950s.

These slow motion shots are without a doubt some of the coolest things I’ve ever seen.

I'm just replaying the shot at 7:05 over and over. Incredible. It's like seeing 2 Kamehamehas colliding.
And also is a good demonstrattion of how a "beam struggle" is kinda wrong, knowing what we know of physics and how light works.
@@FlyingCIRCU175 Depends, a lot of beams out there but in DB specifically the beam is not light.

I am no physicist or scientist but the sheer amount of data that can be extrapolated from this video is invaluable

Thanks for staying true to the original values of the channel and for producing such amazing content! I’m curious to see what you’ll create in 2024!
They shiuld do it again but with perfectly on point collision, they really just need to place them 30cm apart too
Man, that overexposed shot was so beautiful it brought me to tears. The lens flare on the beams and the blue flash from their collision was such a spectacle to witness.
Gave me an interstellar vibe. Felt like I was in space for a sec. . .
I am awe-inspired and glad that I am not the only one who cried at this point.
Gav nailed it with the JJ Abrams quip
Poor man's fusion reactor
This is what happens when science meets art. Amazing visuals, My jaw dropped watching this. Explosions in slow motion are mesmerizing! Absolutely stunning! The precision and chaos captured in slow-mo are breathtaking.
I appreciate that last shot showing the shape charge form the penetrator. Everyone believes that the copper cone is shaped into a projectile. But this video proves that the copper is instantly vaporized. the purpose of the copper cone is to shape the blast to converge to a single point forcing all of the blast propagating in that direction into an explosive jet. And any residue of copper that you see on the hole of the penetrated material is merely the vaporized copper condensed or spattered on to the object. Furthermore, The copper lens material can be made with several different materials including glass or plastic which will also act to form the shape charge.
TLDR, the Copper isn't shaped into a penetrator projectile like it is on EFPs rather it focuses the explosive blast into a jet.
Further more, The copper lens material can be made with several different materials including glass or plastic.
The copper acts as a plastic mass of greater density than what you'd achieve from the expanding gas behind the shockwave.
Remember: If the copper was vaporized, it would expand into a greater volune as becomes a gas.
This is incorrect. The copper liner does become a fluid jet which eats through material using its velocity and density to eat through the desired material. I think the misconception arises from the ranges. A shaped charge of the type used in the video has a range of inches for standoff. By the time it leaves the frame of the ultra slowmo video it’s already past the optimum distance and is rapidly shedding material and losing effectiveness. When shot into the gelatin, since it’s so low density it travels for a range that gives the impression of a bullet, you would never use that small a shaped charge with so shallow a liner for something a meter away. Even on the collision shots, those copper jets are FAR past their optimal standoff range. At the appropriate standoff distance there is very much a jet of copper, from a meter away probably a little bean like we see in the video.
EFPs on the other hand are long range explosives. The liner is a lot more shallow and thicker (like a manhole cover). So instead of the wacky fluid dynamics forming into a hot jet bs that happens with shaped charges it more traditionally forms a slug which has great effect at range.
The theory of shaped charge penetrators is pretty well defined. But probably hasn’t ever been viewed this clearly before. Plus if it was a focusing or lensing effect, we would see it disperse past its focal point, which we don’t.
The 2 million fps shot looks like comets traveling through space. One of the coolest looking videos you’ve done in a while!
2:30 never expected to hear a destiny reference from the slow mo guys, this put a smile on my face
Same lol. Glad there's fans everywhere
exactly my reaction lmao, i had to rewatch him say that like three times to believe it
I can't stand the game anymore but that got a laugh out of me
The precision done with timing both charges to go off so close to each other was astonishing. Both meeting in the center of the cameras view deserves recognition. Well done this video was awesome.
I am more impressed with the camera's capabilities than the imagery captured. Great job to the engineers who developed this piece of equipment.
You’ve reached a new level, this is not just a slow-motion video of an explosion, this is art! Well done!
It goes beyond art - someone's going to be writing up scientific papers on this footage.
@@Solnoric exactly what I was telling my daughter, some one just got their Doctoral thesis!
Pretty sure I saw a Higgs particle fly by too
We definitely need another video where they are perfectly aligned. This was amazing (maybe try linear charges for better chances of impact)
Agree!!!
Let that be, it would be the end of the world... 😱
I wonder if they might be able to aim a bit more precisely by welding on a length of pipe to the 'exit' side of the metal plate, or whether that would interfere with the jet?
There's a million cool things one could try with those things, but I imagine they're quite expensive toys . . .
@@stickiedmin6508 I think the easiest way would be to build a frame/jig. Like, build the frame of a long rectangle and have the plates on the ends, like caps.
@@Erteywie
Are those shaped charge explosives consistently 'accurate' enough to confidently predict *_exactly_* where the jet will end up?
Given the way they're usually used, I wouldn't expect that it's the kind of thing they put a lot of effort into during manufacture.
Before this I honestly had no idea how narrow and tiny the copper jets really were - I imagine it would be frustratingly difficult to get two of them to hit each other _exactly_ square on...
please never quit guys even if its 1 video per year never leave us
"It's like a sausage shock wave." I couldn't have said it better myself. Awesome vid
You guys are approaching (or maybe arrived) a level of quality and entertainment that brings me back to the golden age of Mythbusters

Beyond.
Their golden age is behind them. It's nice that they still try to think of something new every once in a while though. Truth is, they've been doing this for so long they just can't make content like they used to. They've already done so much stuff it's hard not to be redundant and repeat things.
@@bestieswithtesties I disagree
@@bestieswithtesties hard disagree. I feel like every second video is something incredible i've never seen before. Either visually or conceptually. I think they're going as strong as ever.
@@z0bi_ They've already done so much for so long that they're forced to really think outside the box to keep coming up with new ideas. It's still interesting but let's be real.

Hopbophop!😂😂😂😂👆
The superimposed shot at 15:50 is one of the smartest and best things you’ve ever done. Bravo
That white flash is amazing, this probably the best video of 2023 for you guys. 👍🏻
I watched this video at 0.25x speed to make it even slower
Fun fact: copper expands to literally 67,000 times its initial volume when vaporized. That’s why it is used in almost every form of AP shaped charge. That rate of expansion is incredible by any measure!
@@RichyJFilms it’s not even true. Copper is used because of a combination of its ductility and properties when under compression. The copper isn’t being vaporised - the exact opposite is happening. It’s being compacted down into an extremely thin rod of 10kmps liquid metal.
Copper vaporisation expansion isn’t why it goes bang. Thats the result of the high explosive. Copper expansion is a problem for other fields, like metal works dealing with copper powders etc. if they go bang, they go bang very loudly.
As i believe the world to be, so it is.
But isn't the effect the exact opposite? They want to concentrate the copper into a smaller projectile of molted material so it goes through whatever it encounters more effectively. It also concentrates a big amount of energy in it.

Make sure your facts are actually supported by fact next time you claim something.
Copper does NOT turn into plasma, vaporize nor melt into a liquid. It simply is plastically deforming under extreme pressure. No phase change is happening in the copper.
Although metal does behaves in a quasi-liquid like state under those extreme forces it's not actually a liquid, Common misconception
From cans of axe body spray and backyard water balloons to shaped charges in Colorado. So glad you guys have made it this far. Thanks for all the content you guys push out:)

Pretty much every other slow-mo project: “we need more light!”
This one: “we might not have enough ND filters.”
Whats ND?
@@MISHBASHneutral density, I.e grey.
@@DrDeuteron They're not exactly grey, at least none that I've ever seen or used (not that grey can't exist). The footage looked grey because at those speeds, the video is shot in black and white
@@DrDeuteron It's _neutral_ because it decreases all light equally; it has a neutral preference of light reduction (I assume absorption). Most things are frequency dependent and different wavelengths come thru different. With the ND filters, you get a net reduction with no changes on color.
@@caodesignworks2407 They pretty much are a perfect grey. Not just appearing grey to us but just a flat absorption all across the spectrum.

Greetings,

That is not correct. It ionizes and turns into a sort of gas. It does not melt. This is also why you do not find melted copper on the battle field, it evaporates instead. Watch a few battlefield clips and you can literally see it evaporates into a yellow mist/gas.
The rod is hydrostatic(or act like it), it does not burn its way through the metal, it pushes through like when you drop a rock into water.
Jousting with fire.
That's a new one.

Now Iwant to see a high speed video of a shape charge in a vacuum chamber. If its moving though a vacuum will it still be glowing so bright? Or is most of that from ram pressure heating IE. its like a meteor burning up when entering atmosphere? Without air will it just be a chunk (or spray?) of ordinary copper flying by really fast?
seems dangerous for the vacuum chamber, though. Guess we should just send Gav and Dan to space :D

This is Absolutely Awesome! I'm a Special Effects pyrotechnician in the film industry. I've been using PETN shape charges for over 30 years, primarily to blow out tires on moving vehicles. I mount them to the suspension. I've understood the principle and have seen the results but this is the first time that I have been able to actually See what is happening in real time.

Y'know, this footage can help engineers improve the design of the charges. Being able to see the real world charge affect vs the mathematical models is really extremely useful.

Let's be honest here, if the idea has occurred to us, they're probably already planning it...
This is a great friendship across an ocean and half a continent.
First time watcher. Loved it. I think the bright light is lightning. The friction of the 2 jets are creating lightning. Congrats a new way of producing electricity. But I would love to see a dead on hit. 👍
Gavin - you should do a video about neutral density on the 2nd channel. I'd love to learn more about that
ND filters just reduce the light entering the lens. They allow you to decrease the brightness with the same shutter speed (like he talks about in the video) or maintain the same brightness with a lower shutter speed. Lower shutter speeds (longer exposures) create motion blur. Think long exposures of bodies of water that make the water look smooth and give a dreamy feel.
It's just a filter that's dark, so there's less light entering the camera. They usually come in stops (and it's logarithmic), so an ND3 basically lowers the incoming light by 1 stop.
The quickest explanation is sunglasses for cameras. 🕶️
If you want to shoot with a filmic setup, you film at a 180 degree angle. So e.g. 23,976 FPS, and a shutter speed, at twice the amount.
But if you do that in sunlight, your video will get over exposed. So you give your video camera sunglasses on - ND filters.
Do a search on the 180° rule in cinema.
Not disagreeing with the rest of your comment, but that's not what the 180° rule is.

For some reason I find the overexposed footage of the first attempt more fascinating (or better word beautiful?) then the less exposed footage. The blue colors and the flaring looks so freaking cool, like from a sci-fi movie (Gav already mentioned 2 Death Stars duel). Amazing footage, what a banger for the end of the year.

Thanks Colorado School of Mines for letting them film this. Very Interesting.

I'm fairly certain it would get even brighter. Assuming a perfect collision both jets would be decelerated to 0 in an even shorter distance and time than they were originally sent scooting. The conservation of energy states that all the kinetic energy would be converted to thermal energy. I wouldn't be the least bit surprised if we got well into the X-ray spectrum...
@@andersjjensenThat's how you expose Dan to enough Gamma radiation to become the new Abomination.
also I guess similarly to what I think Smarter Every Day with bullets, they would also shatter the material of the cones outward, perpendicular to the direction they were shot at.
This content is so obsessively fascinating
You guys are building an archive of some of the most remarkable footage ever captured.
I cannot believe how Slow Mo Guys can still make a better video every single time when you already thought it was the coolest and best video!!!! good job mates
Bless Dan for trying to make a "just the tip" joke in the outro at 16:49.
Wow! This is stunning, indeed. Pushing the cameras to the limit.
This video is just phenomenal. This might be one of my favourite videos of yours, which is no small feat.
It's just surreal that it's possible to achieve slow motion to this extent, and especially for something so fast, bright and short-lived.
Having to stop the lens down to F22 AND a 6 stop ND on top of that. Just crazy
The destiny reference at the beginning really caught me off guard
congrats for 15 MILLION subs gav and dan
Dan your looking good!!
Good job sir!
Bruh that destiny joke was spot on
2:40 really cracked me up
Mind-blowing! 15,000MPH colliding explosions in super slow motion is a visual masterpiece!
This is hands-down the best video you've ever produced. That footage is absolutely mindblowing.

This footage left me speechless. EASILY some of the coolest visuals I’ve ever seen. Phenomenal job, team. Holy crap.
Also, coming to this straight from the waxing video was quite the mental whiplash. lol
😂👌🏼
One of your most dramatic and BEST videos to observe.
Wow... just wow. Thank you guys.
Hope you guys enjoyed Colorado! Im sure SOM was glad to have you!!! Cheers fellas!!
No... we didn't enjoy these clowns. They have zero education, they spent the last few years on firearms and explosions simply for the "views". Absolute waste of our resources.
@@Katchi_ lol sure, sounds legit. Zero education? You know one of them is an explosives and demolition specialist? Go post your fanfiction on the appropriate sites 😂
I think CSOM is more relieved that they haven't stacked explosives in another toilet, cos last time the entire quarry nearly got blown up.
@@blobfish. He maintains zero "demolition specialists" credentials. Explosives credentials are entirely for tracking.
I love that you are still finding subjects that push the technical limitations of your equipment after a decade of progress. Goes to show that there is still so much interesting content yet to be made to look forward to.
Это просто невероятно, спасибо за подробную визуализацию формирования комулятивной струи👍🤝
Best ballistic gel video I've ever seen.
