Gavin somewhat-nervously describing how he has to push those cameras further than he's ever before is just awe-inspiring.

[@Hydrazine1000]

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.

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.

8:06 The childlike joy of Dan's "I wanna do it again!" comment. Priceless.

[@mikip3242]

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.

[@sireuchre]

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.

[@MultiJimWilson]

@@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.

[@bigbomb5904]

WTH this is what happens in space during star explosion 🤯. And people study this their whole life.🤯

[@mikip3242]

@@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.

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.

Gavin - you should do a video about neutral density on the 2nd channel. I'd love to learn more about that

[@samuelpmoran]

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.

[@DaedalusYoung]

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.

[@GenericaQwerty]

The quickest explanation is sunglasses for cameras. 🕶️

[@akyhne]

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.

You get two copper cones.

[@dream.fiiend]

Blackhole forms

[@andersjjensen]

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...

[@TheRealSkeletor]

@@andersjjensenThat's how you expose Dan to enough Gamma radiation to become the new Abomination.

[@MrXPeaceLP]

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.

[@DAngelProductions]

That was most impressive slow mo video I’ve ever seen! That lense flare and colliding was absolutely brilliant!

[@AnakinSkywalker175]

Nice Darth Nihilus pfp

[@alexvanpelt5119]

I used to watch SMG for the entertainment alone. But now, I'm spellbound by just how much technology reveals the world we cannot normally see. Microscopes, telescopes, high-speed cameras. This tech shows just how finely-tuned and minute physical and processes are. Incredible. Thanks, Gav and Dan!

[@user-sx1fg7lc3c]

These guys get the greatest footage in the world. Hands down coolest footage on YT

[@PlaneAwesome]

Bless Dan for trying to make a "just the tip" joke in the outro at 16:49.

[@marsrocks247]

SUPREME editing. So DOPE to see the different shots laying over eachother.

[@coltondavis401]

I’ve been watching these guys since middle school and I’ve been graduated since 2020. Absolutely love these guys and how far they have come!

[@InsTAus793]

This honestly has to be the most IMPRESSIVE video you guys have made so far on the subject of explosives. It's amazing to see it in so much detail in such a teeny, insignificant amount of time (6 microseconds). Well done, guys! Thank you for another fantastic video

[@NigelStratton]

The images at 7:00 are clearly the most impressive frames ever recorded by the Slow Mo Guys!

[@stevevernon1978]

I seem to recall one where they photographed the speed of light.

[@stickiedmin6508]

​@@stevevernon1978 Yes, we remember. It didn't look as cool as this.

[@youractualdad9733]

Ending the year with a bang. Cheers Mates! Thanks for always bringing some awesome content my way since I’ve been about 14 you are one of the single best KZbin channels in my opinion

[@stickiedmin6508]

[@micahphilson]

The way it causes cavitation through the entire ballistics gel just tells you how fast it's going and how much power it has!

[@Lyndonberg_Gaming]

13:22 love the fact you guys captured the plasma trails

[@deadbyfaith]

This is absolutely amazing. Just an idea, what if you did this again but shot both shape charges at the ballistics gel. I would be very interested to see how the gel reacts to getting hit from both sides at the same time and to see if you can get a collision inside the gel. The gel also helps a bit with the exposure, too.

[@justintimeforonce]

This is one of the coolest videos you've made in a while, I keep thinking you've exhausted all the coolest slow mo ideas and you keep coming up with more!

Thanks! Absolutely fascinating. The footage is amazing and you guys are quite entertaining. I appreciate it.

[@Anu_r303]

You guys should use ballestic gel between shape charges...

[@litapd311]

it was super cool seeing all the shots on one screen over each other, thank you for the edits

[@ritwikverma8140]

This is one of my favourite videos on this channel. Love the way you all push the absolute limits of the hardware.

[@frogdude1337]

I don't have a clue how the cameras or these explosives or anything works, but I think it is incredible. Having the daylight be pitch black and the explosion moving quite clearly in the dark is really cool. And comparing that to the slower colour footage is incredible too. The frame rate difference is huge and it is just a white cloud in daylight. It is awesome

[@melanp4698]

How the cameras works is pretty simple. If "normal vision" is 60 frames per second, then 600 would be slowed by 10 and 6000 would be slowed by 100. So at 6 million fps, 1 second would last almost 28 hours :)

[@GodmanchesterGoblin]

​@melanp4698 I think the point was more about how they work... not about the basic maths. So, how does a sensor capture light in a meanigful way in less than 100ns? How do you access the data for tens or hundreds of thousands of pixels in the sensor array over and over again in fractions of a microsecond? (The data rates are quite challenging.) How does the huge amount of data get buffered before it is committed to slower non-volatile storage? Etc. These are very challenging engineering issues, and the camera builders do an amazing job, imho.

[@mr._.mav792]

The destiny reference at the beginning really caught me off guard

[@katchaontheflipside]

Wow guys, just wow. The images at around 07:00 will stay with me for a while. Just awesome! Have a great new years!

[@chaochaocingdream]

You should do it again and capture the shape charges collide. That would be so EPIC

[@pyontasansan]

Ok, I have to admit I chortled a bit at 2:37. Almost laughed my snack I was enjoying outta my nose- friggin funny dudes.

[@Cypher7765]

You underestimate how much shaped charges tingle my brain.

[@8266]

Couldn't have said it better myself, and then also the ideas they have to try just makes my soul happy

[@Soken50]

I think they'd feel like a bit more than a tingle if they encountered your brain ;)

This might be the most beautiful slowmo video you've ever made.

[@Fenomen001]

Dziękujemy. more explosives project !

[@motiz88]

This might be one of the best videos on this channel. Love the sense of genuine curiosity.

[@pedrodu3626]

The production on this one is AMAZING.

[@dotkomist]

That comment from Dan at the end is what blows my mind every time I see a shape charge video. I imagine there will have been testing and simulation for sure, but these must have been developed, essentially, entirely theoretically, without ever knowing what exactly was happening! Science is so cool.

[@melanp4698]

Most of science has been like that through the ages :)

[@canibanoglu9643]

That was a fascinating video. And to think that you need to go even faster to stay in low earth orbit is mind bending

[@cr0ss0ut]

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.

[@BogeyTheBear]

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.

[@EriAntTea]

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.
