[@Nighthawkinlight]

I've always wanted to film this but just assumed the sparks would be too dim to really see with the lighting required for high speed. Really cool footage! Edit: Oh, and also I had no idea this was triboluminescence! I thought it was peizoelectric arcing

[@SmarterEveryDay2]

What's up Ben, good to see you here man. Yeah I thought it was "static" and never really thought about it much more than that. Obviously it's not because it's a mechanical event. There are many journal articles on it. scholar.google.com/scholar?hl=en&q=triboluminescence+life+savers&btnG=&as_sdt=1%2C1&as_sdtp=

[@Nighthawkinlight]

Thanks Destin, rock on! I'm going to have to do some reading.

[@leightonwestbury92]

hey man love both your channels .........just a thought what about if you compressed it to the point of fracture or put it in a clear pressure tank till it fractured, just curious what results you might get :-)

[@jman8253]

Going off the wikipedia page for Triboluminescence: "Triboluminescence differs from piezoluminescence in that a piezoluminescent material emits light when it is deformed, as opposed to broken."

[@brokenacoustic]

Get a chunk of quartz and a burr ball bit for a dremel and grind the quartz, it has the same effect, but is nearly continuous.

[@squidcaps4308]

Sound engineer here, want to shout out to sound design too, was going to so great to have it at the end of video. kudos to a fellow colleague, nicely layered splinters. Would not at all object to a short video showing the project and how he does it, always great to see tips and tricks from others.

[@LyndanTylor]

I figured it was fabricated sound, but didn't know for sure.. Then I wondered if he paid someone to do his sound design and he answered all my questions at the end! Hahaha.

[@nottilus]

Was wondering the same, so relieved at the end haha

[@Aspenflight]

Agreed, the audio is very impressive.

[@ashellinthepit]

Greetings fellow soundy! My main trick for these videos is reverb for daaays & a lot of pitching. I do spend a lot of time choosing the right sounds and being as meticulous as possible with sync when I can--which I actually wasn't able to do as neurotically as usual for these but luckily no one seems to have noticed (shhh).

[@BandanaDrummer95]

You still did a fantastic job of creating a sound that doesn't really exist. And hey, good news; we're back in the Tony's.

[@kcwidman]

Your telling me this sound is manufactured? That is even more amazing than when I thought the sounds were natural. I am astounded at the intricacy of the audio.

[@aliwahay]

Kai Widman my reaction exactly

[@einname9986]

Kai Widman I admire the sounds during that video too. Sound creators for Films are people you would never think of, when you think of the production of a movie, but without them, every movie would be boring. If you'd really record the sounds during the shot and replayed them so slow, you would probably not be able to hear them, since the sound gets deeper when played slowly (sound waves stretched or something like this).

[@smartereveryday]

[@MateusAntonioBittencourt]

Ein Name Holy Cow... Those sounds effects are SO good that made me completely forgot that slowing sound to such a degree would low it into infrasound. I fell to dumb.

[@wesleygregory2562]

This reminds me of the lifesaver commercial from the 1980, that has a couple on a couch and one of them says if you “bite it in the dark it makes a spark” then they turn the light out.

[@goatlps]

This happens when biting them too?! Sounds like total agony on a filling (old school mercury grey fillings)!

[@MrShakamuni01]

@@goatlps gosh never considered that. Did you actually get a zap feeling? I know Dr Tenet does a lot of work with tooth voltages.

[@seanmessick9330]

@@MrShakamuni01 no, you don’t feel anything from the spark.

[@spvillano]

@@MrShakamuni01 not really a spark, it's crystaline fracturing exciting electrons that were formerly bound to a partner. You can get the same by striking quartz crystals together, rubbing them together, etc. Cellophane tape unrolling also generates the phenomena, as well as x-rays sufficient to actually x-ray a researcher's finger in a vacuum chamber. Electrons are very excitable things.

[@soulchorea]

Me and my friends used to do that all the time; worked best with the spearmint ones - stand in front of a mirror with the lights off and you can see them spark when you crunch down

[@SnapSV]

So if i eat enough of these at once and crunch down i can turn into the flash? got it, gonna go buy 50 crates

[@AmorDei316]

I used to do that when I was a kid it's only works with the peppermint Lifesavers but if you go in the bathroom and turn all the lights off and chewing up really quickly with your mouth open you can actually see Sparks and flashes in your own mouth.

In the middle of the video, I was thinking... WOW this guy has an AMAZING Audio Engineer. These sounds are incredibly well done. And I'm so happy that you explained this at the end so that others can know that there is an effort is put into these videos beyond what meets the eye. Most videographers these days have audio engineers behind the scenes bringing to life every detailed frame that our eyes see. Such an underrated job. We love you Audio Engineers!! PS. As usual, Destin your video is amazing! I absolutely love lightning in slow motion!! I had never heard of Triboluminescence before. You earned my subscription to this channel about 5 seconds in as I thought to myself "Why in the world am I not already subscribed here?" Keep up the amazing content and thank you! And thanks to KZbin's weird algorithm for recommending this video to me 3 years later. Happy to finally see it.

Thank you so much for answering the audio question! I was thinking about it during every shot and was almost convinced it does. Says a lot about what a good job they do matching up sound effects.

[@relevant1683]

Honestly, this is the coolest thing I’ve ever seen in slow motion! I don’t know why, I would watch this for hours.

[@Sudz3]

Ok Destin, not sure if you are going to read this but: There was a video about Scotch tape being ripped in a vacuum, that caused both Triboluminescence, as well as X-rays. Not just a little bit of x-rays... Enough to develop film. It was significant. (but required a near perfect vacuum) It looked IDENTICAL to these lifesavers, and the theory behind that is that scotch tape isn't a physical bond, but a chemical bond that when ripped apart, releases energy in the form of light and radiation. I would LOVE to know if this would be the same result? Do you have a way of measuring x-ray radiation? Science!!!

[@kylandaminick13]

duct tape being pulled apart produces light also and it works at atmospheric pressure.

[@josuelservin2409]

There was even a proposal to make a really small low cost x-ray machine that work on that principle

[@NinetyMinusTen]

I see similar blue sparks when opening my Breathe Right nasal strips. Easy to see with the lights off.

[@starcitizen890j5]

Sudz Opening self sealing envelopes causes blue light to be given off also.

[@giin97]

OK, everyone offering examples? ALL adhesive strips spark when you pull it apart. There, I just covered every possibility, Lol :D

[@austencline8500]

The part that fascinated me the most was that during one frame around 4:31 you could see the blue glow beginning to spread before the pellet has actually struck the candy. At least, it appears that way with the streak of the pellet visible to the right of the lifesaver. I wonder if the shock wave travelling in front of the pellet, as it moves through the air, is creating enough stress to start shattering the lifesaver. If that's the case, couldn't you just fire a bullet past it but close enough for the shock wave to shatter it?

[@Overmann55]

I believe it was the force traveling through the lifesaver from the front part being opened up - as if a wedge (the pellet) was driven in and forcing the part in front of the pellet to separate. Maybe?

[@AC_Marshy]

Do high speed cameras have rolling shutters? Enough that, if the right part of the frame were captured first, the bullet would have moved ahead by the time it started capturing the impact point?

[@samueldurazzo5312]

Sorry I am late but yes the high speed cameras have a rolling shutter (all cameras do) and the usual scanning pattern is either top to bottom or left to right. This is causing that effect, not a Shockwave (:

[@bueb8674]

@@samueldurazzo5312 Phantom cameras (and most good high speed cameras)have a global shutter. They need to in order to be useful for any kind of research

[@ashtonsenko536]

Shockwaves only come from the barrel of the gun, from high pressure and gas escaping, not the bullet.

[@IttyBitty412]

I love that this dudes always smiling and so excited to do these!!! Looks so fun too. Love this so much

[@gideonmckenzie1797]

This is amazing. It looks so sci-fi esque, especially when shot with the pellet gun. wish I could get a clear frame of the gun one for a desktop background.

[@ianmcconnell5973]

Watching the sparks appear primarily along the fracture lines, I immediately thought of the reports of "earthquake lights" reported by many witnesses in areas that have suffered earthquakes. I am guessing it's the same effect, only on a much larger scale, as energy is released at the moment of fracture. Great videos!

[@TheMinecraftSandbox]

Hey Destin, any idea why on the last shot, at the time +0.25ms, it looked like it started glowing blue before the bullet hit? Anyway, great video!

[@MattStum]

Was going to ask the same thing. I wonder if there's a shockwave of sorts in front of the projectile?

[@Lovreli]

Kieran | TMS roling shutter

[@swimmerdude299]

Not a scientist but it think what happened there was the bullet was traveling faster then the camera was recording, so when they went frame by frame to slow the already recorded video down more the bullet got blurred and stretched. Kinda like if you swing a glow stick on a string in a circle it looks like it makes a solid ring of light, same idea of blurring.

[@Ali-yh8dl]

i was wondering the same thing, it might be because how the camera takes footage and stitches them to make a video like he explained in one of his videos when shadows seem to go before the objects does

[@Lovreli]

[@pokerraper1]

@karim lavji I'm not so sure about it. Light is fotons after all, and even when they don't have mass, they do have electrical charge. What I assume is that there is so low electrical charge you wouldn't feel anything, or the "crush" you make isn't enough to make them. I'm curious about it, if it releases the charge because they have an electrical charge from the beginning, or because of friction.

Hey Destin, have you experimented with different types of sugars to see if the color of the triboluminescence changes? I’m curious if sucrose and fructose would yield different colors, or if a more crystalline sample (transparent rock candy for example) would give you a different result.

[@thomasrrgsd]

TheWyrim The spark reacts with nitrogen to produce ultraviolet radiation. That is absorbed by the lifesaver, creating the color you see.

[@arjen4120]

Osama Rana the light is at places where it breaks. its not that it breaks where the light is.

[@OsamaRana]

I see what you mean, but the light appears before the crack, so to me it seems like the sparks are...almost weakening the candy, making it susceptible to breakage. Does that make sense?

Ooo. It is? But it looks like have some power...

[@mrnat3058]

Yeah, but I'm not sure if you could do a whole lot with it. I've also seen people talking about scotch tape giving a similar effect, and producing x-rays when it is torn in a vacuum.

[@Croiso]

Okay then. Thanks for the info👍

[@giin97]

Mrnat all adhesive strips do it. Spend a few minutes in complete darkness and have fun.

[@Zoidberg227]

Maybe ... the minimum ignition energy of a hydrogen-air mixture is a scant 0.019 mJ, which I think is less than you can even feel, at least readily. Casual Googling has not revealed how much energy is liberated in this case. TL isn't that well understood ... it quite likely involves the movement of electrons, but whether they are moving between orbitals or between larger discrete particles I'm not sure. It would definitely be interesting to see this performed in a carefully controlled hydrogen atmosphere.

[@ricardomuck4537]

Why is it blue? Is it just the amount of energy?

[@soylentgreenb]

Yes, but it is not well understood. Unrolling scotch tape will also generate a blue glow (also triboluminscence), but in a vacuum you will get x-rays. Quite a lot of them. Enough to make an x-ray image.

So who knows, if you suck all the air out of your mouth and then bite on a candy, maybe you'll give yourself a brain tumor ;)

hey i just said that so it must be true

Your audio guy is a genius.

[@RitaMaru11]

The footage is so cool

[@Laithalnasser]

Question: Can this spark produced by the candy ignite some fuel or gas?

[@kellyjackson7889]

Test it and see report back

[@anthonymichael7888]

No.

[@JORDEN7491]

Lathem HD it will be a life saver if it did

[@mythrin]

Emmanuel Martinez Badum tsss

[@Kyoobur9000]

Sadly, no. To the best of my knowledge, the "sparks" aren't electrical. They're just light.

[@huyked]

4:20 Wait. What the heck? Did the air pressure at the front of the bullet cause the triboluminescent, or did the bullet touch and we didn't see it because it was dark and had no reflection?

[@SLACKLINEDUDE]

Im calling air pressure.

[@pursueexcellence7737]

I think its because of how the camera captures each frame :)

[@huyked]

Sameer Tariq Yeah, it's up in the air for me. I'm just not sure.

[@geometricdashingjorge1945]

Now this, this is epic
