Exploding Prince Rupert's Drops at 1 000 000 Frames Per Second!! 

Hey Destin , how can they fix the video so i don't get dizzy when i watch the slow motion footage?

@@alexarchuletta3698 Make the ring holding the cameras spin in a circle instead. I don't think that'd be easy to pull off at the right exact RPM to get the shot to be still though.

Really Destin!! I like your prince Rupert video.it is very informative.

@@craigcampbelljr.4097 The rig would have to spin at about 600,000 rpm to capture 1 million fps which would blow the rig apart well before ever reaching that speed. The spinning is unfortunately a necisary part of filming at this fps in this level of quality.

lol you should get this chronos ring set up too!

@DIE Shia, did Himo arrive safely?✈👍

I don't think so. The trails form a semicircle with the same radius as the container and the end of the trails correspond with structural failure points in the glass. Seems to be a shock front maybe? There's also no evidence of fragments hitting the water.

@@guyincognito. Well, it couldn't have been the air shock wave, it's too slow. And not the water one, even though it's way faster. Because the "trails" started instantly when the breaking front hit the water. It didn't have time to bounce back from the walls of container. If the trail was delayed then I would agree as a definite possibility.

Scrap the water shock as well. It would have come back to single point and formed a fountain or smth.

@@Armuotas I agree. But it's hard to discount the fact that the trails form a semicircle with an apparent radius of that of the container. I also can't see any fragments appear to hit the water that would coincide with this pattern. Can you see the structural failure of the container match the points where the trails meet the container walls? The semicircle trail is composed of tiny splashes of water but there are 2 much bigger splashes right next to the container walls where the trails end.

@@guyincognito. i.imgur.com/yRvWjH3.png It's super easy to discount since the "circle" is larger that the diameter of the container, the trajectories of the two clusters are different (possibly because of the distances to the surface), and they don't reach the container at the same time. I'll stay with the "fragments torpedoing the container walls" theory. Still need to explain the actual bubbles. I'm working on it. Perhaps the fragments at the glass-water interface did some secondary explosive fragmentation or smth.

I like this idea, maybe clear ballistic gel so it still has lot of flex.

@@redsquirrelftw or clear silicone

That would be interesting.

I was really surprised how good the 1 000 000 fps stuff is

Dont forget his superduke r to the racetrack

You would still be able to say that even if the internet didn't exist.

@@ArchangelExile Be able to, yes, so long as they knew them, which, without the internet, is rather unlikely

[SAW]Spitfire Honestly? I really think it should be standard for research teams to immediately publish videos they take for data. Everyone (including other researchers) gets to see experimental data right away and the researchers conducting experiments get to monetize the videos for extra research revenue. Plus, nothing is behind a paywall, like when they publish through journals.

The target was so bright that on one of the videos I had somebody holding light for the sights to match them with the target :D

@@Beyondthepress Lol, that is most certainly bright. Pesky super-slomos and their thirst for photons...

It honestly isn’t that hard

if you have some practice with a rifle it isnt hard from such short distance

Cmon u gotta argue over a compliment lol

Well, we also had Simo Häyhä :)))

I've shot a playing card in half at about 30ft with a .22lr using only iron sites and no bench rest. It's not that hard.

I noticed that the container broke from center of bottom outward, then the hydro shock hit the walls....

Rick Dangerous the resolution is terrible

@@whip8 Let me guess... you're a millennial...

Seems like a lot to spend on cameras for such low resolution. Could have bought two better cameras and had a stereo shot with clear picture

@@whip8 High speed cameras have to move an insane amount of information at an impossible to imagine rate. Just a few seconds with a setup like the one in this video at full hd would require a ridiculous amount of DRAM that no camera on earth has. To put it in perspective the camera in this video can record a million frames per second. So a single second captured from it, played back at 30 frames per second, would be over nine hours long. The fact that this video is even possible is insane.

@@theseabast6515 again... millennials... they just don't understand.

Set video to 4K, even if you don't have a 4K monitor. The 4K preset on youtube not only increase pixel count but overall bitrate. You won't get any more detail (since the Chronos Ring footage is a low resolution), but you will keep RU-vid from taking away more detail, lol

They showered and changed clothes while waiting for the pellet to hit the tail of the drop, they were washing the glass dust off from the second test.

Hey folks, thanks for showing how commerce can drive scientific advancements. You make money, we get entertained, and this data is available to all of the sciences. You're helping to drive understanding by making this experimental data. Data which would be unavailable to almost anyone with insane grants. Thank you for my enjoyment and for the knowledge you're helping disseminate.

sitsia i’m coming* HPC is from Finland so i commented in finnish:) Cause i am from Finland to

@@ilari6sto yes i know very well they are from Finland and that you wrote in Finnish, i just didnt understand the text as i dont live in Finland but in sweden

@@0snowfall330 Cameras do exist with that frame rate but with very low resolution.

@@AntonyTCurtis the highest camera rate was something like 10 trillion fps, the scientists filmed light moving

Thats just the nature of the extreme high speed capture of this setup. The ring of 72 cameras are firing in sequence, and the final image you see is a series of 72 sequenced single images put together which is why it looks like you are circling. If you slow down the spin, you increase the time between each single shot so you would miss details. The ring mounted cameras and the resulting spin is the compromise to get as much high speed detail as possible. There would be too much paralax error if you set those 72 cameras up on a single side to try and capture the image as the object will be jittering around instead and probably give you more of a motion sickness feeling.

@@alexb.1320 the United States Air Force arranged a ring of cameras, and had a rotating mirror system to get the ridiculous frame rates back in the 50s and 60s. Maybe they just need the idea from people like you to inspire them. Thank you for telling us about this!

@@alexb.1320 rotate the subject in the same direction and it would look still! Try and hit that with the air-rifle 🤣

Also notice how it starts to shatter from the top, even though he hit it a couple of cm from the top

@@tehsimo And that the pellet is visible in multiple rotations of the perspective also tells a story about how fast the cracking propagates through the drop. It's crazy fast.

We have the technology to film laser beam moving throw liquid. Its just super expencive and pointless.

Search "How fast does glass crack?" The slow mo guys did a video on it. Actually a few i think, but that's the most recent and highest speed footage i believe

​@@Otto3339 Otto, that's not actually true. We don't have the ability to film the movement of a single beam of light. The filming of the laser through liquid that you're thinking of is actually accomplished with just INCREDIBLY accurate timing. So what they do is, fire the beam > take a picture 1 billionth of a second later(or so). This captures the laser at that exact point in time. Then they fire another beam and take a picture 2 billionths of a second later, then another and they take a picture 3 billionths of a second later. By doing this over and over, they can then play the individual frames together like a movie. Since the light is pretty much doing the exact same thing each pulse you get a pretty good representation of what a single pulse of light would look like, but it is NOT a single pulse that you are seeing.

@@nahog99 well i dont know. Watched the slomo guys's video on it. Just search slomo guys laser

@@PyroNinja713 Seen it, long ago. But that is not the kind of glass we are talking about. I don't care about tempered glass, that is just "normal" glass. We are talking Prince Rupert's drops here. And not even the Slow Mo Guys were able to catch that. I was hoping to catch it here, this is the _one_ thing I was waiting for since they announced the Chronos Ring videos. This was the _only_ thing I was really interested in. Hell, the Slow Mo Guys did a video on shattering Pyrex, and even that was too fast. They even uploaded the raw footage from that, something crazy between 15 and 24 hours of high-speed footage, of just a fraction of a second. And not even that was fast enough, the cracking was still instant. I want to see the cracking crawl through the Prince Rupert's drops. If you ask me, the pinnacle of high-speed photography/cinematography has not been reached until we can capture cracks crawling through broken/breaking prince rupert's drops, in high definition.

The answer is: Carefully 😱👍

Can't at all? Probably tongue at the wrong end of the mouth. It needs to be forward, try "ro" (or even "row, row, row your") without moving your tongue or lips from their position for the "o". For the r, you just need to thicken the very back of the tongue without pulling it back. Pressing it down flat may help there. If it still doesn't come, try fake snoring with your mouth in that configuration. If you got that, move the vibration forward until it hits the back of your tongue.

Too bad it would cost enormously. A Phantom v2512 can be *rented* for a day for around 4000$ a piece. Buying them would cost millions. 😂

Buying a single phantom would cost as much than all those cameras combined, depending on the model. The best ones cost 6 digit figures.

I am pretty good with that cheap air rifle :D it took some time to get used to those sights but now I can put two bullets through same hole in 10 meters with couple tries

Here i am with none!

They seem to be parallel to the path of the pellet and persist throughout the video. Intriguing.

It's like a curved shockwave and appears to have the same radius as the container. Even seems to have peaks and troughs like an interference pattern but I don't think it would propagate to the sides of the container and back that quickly. The ends of the 'streamer' seem to correspond with major structural failures in the glass.

@@pattheplanter ah I see what it is, the pellet impact makes a circular spray of debris that hits the water surface, quite ordinary :D :/

"wheyaow" -Owen wilson

Did you also notice how the shatter of the drop did not happen from the impact point of the tail (even though there are shards of glass breaking away from the impact itself), but from the tip, from where it travelled down the tail, though the impact point and then on into the 'body'.

You should watch smartereverydays video on the same where he explains more of the physics behind why it happens like that

The glass bowl exploded because water is an incompressible fluid, it would have ruptured regardless of where you placed it. The pressure wave from the exploding Rupert's Drop was entirely absorbed by the walls of the glass. If they wanted to keep the bowl intact, they would have needed to line the walls with some sort of membrane that would compress and absorb the energy of the blast. Good thought though, it's fascinating stuff.

Ken Haylock Well, the word on the street is that crack moves fast. Now we have the science to back it up. :D Great job guys!

It's max velocity is believed to be 4300 mph

@@SoulDelSol I guess it was one of the lower framerate clips that had the drop lasting 3 frames...

There is a huge amount of stored energy from when it was cast. Now you know why large telescope mirrors take 4+ months to cool down.

It probably has something to do with the overall shape of the crystal structure within the glass

Inside the drop is under pressure because it was still molten when the outside became solid

Zacthebomberman The outside solidified nearly immediately, in which it shrinks, while the interior is still molten. . The inside was still hot, thermally expanded. As the inside cools it then shrinks and that puts huge compression on the surface, since the surface can no longer shrink to accommodate the interior’s cool reduced volume. Glass does not crystallize. It’s amorphous.

Glass is always in somewhat "liquid" form, there is no thermal point of solidification or melting. Just a very wide scale of variant viscousness. Old windows are thicker on the low end, because the fact that glass flows slowly. I think that in case of pr. Ruperts drops the encased potential energy will balance off during very long period of time.

"Notices your comment" OwO what's this?

@@Juni_Dingo O-oh..uwu

Haha that's not a weed grinder that's the container of pellets for the gun 😂

P.S. and for extra content we have here a shark made of glass with dangerous sharp teeth it might take off a finger!! so we must deal with it at 1 million frames per second!!😁😁😘

Maybe it was the first successful shot. 😄

"Air is a spring, liquid is not" I almost lost my right arm at work ~10 years ago, because i forgot that air is a spring.

Looks to me like the wave went straight through the putty at the bottom, skipping the water all together.

@@ivywood13 the skip you speak of is the result of the incompressibility of water

Yes it's even more confusing for Indonesian/Malaysian speakers as the way he says "air" is a perfect pronunciation of the word "water" in those languages. Gets me every time.

And what would be the point of that other than a more fluid but less accurate depiction of reality?

@@Coastfog You said it all, more fluid so you do not need to rotate this fast, it makes my head ache.
