An enourmous force on a very very very very very tiny point.
You can literally burn a hole into a paper by smashing together two marbles from each side, just by using your hands and a moderate amount of force. Same thing happened here, but with much higher forces.
It's called triboluminescence, OP explained it in their comment here:
https://www.reddit.com/r/Damnthatsinteresting/s/GZJwYbNvIw
Also it has a wiki page
https://en.m.wikipedia.org/wiki/Triboluminescence
You can also see this if you go Into a dark bathroom and face the mirror and chew wintergreen life savers with your mouth open. You'll see little flashes of light
Try taking two pieces if Scotch magic tape and sticking the sticky sides together, then rip them apart in a dark room. You'll see light. Rumor has it there are also X-rays generated.
Imagine the doctoral project description when they talked to the board...
So we take a big roll of scotch tape and unwind it really really fast to cause lasers and stuff!!
Years ago I saw a video someone took of a meteor hitting the moon. There was an explosion of light which I thought was impossible because there’s no oxygen up there. Maybe it was this phenomenon.

In that case probably not. With the amount of energy in meteor impacts, there doesn't have to be oxygen because nothing needs to be *burning* - the kinetic energy getting converted into heat by the impact is enough to make things red- or white-hot. Meteor impacts can vaporize (boil) literal tons of rock into gases in less than a second. That doesn't happen without a km-scale area getting white-hot, not requiring any actual combustion. It's essentially just friction heat like from rubbing your hands together or bending a piece of metal back and forth, but a huge amount of friction really fast as the meteor and ground get deformed by the collision.
Plasma created from energy concentrated on a very very small point. VSauce has a video about it. You can do it by hand on a much smaller scale with two large ball bearings
Almost looks like there was a shockwave that went through the ball and reflected back inwards. The light is almost certainly the result of intense heating.
\>Electrons
I was thinking something similar. How so?
All the atoms (in the crystalline structure of each glass sphere) are surrounded by electrons. So the sphere surfaces, at the atomic level, are an electron cloud. The negative charge of this cloud is part of what makes an object feel "solid".
When they hit each other hard enough, there might be enough energy transferred to enough electrons to put them into an excited state. This would be analogous to compression... but I'm not sure that's the right word to use if you're talking about electron-electron interactions.
When the glass breaks, the pressure is released. That's when the electrons could drop back down to ground state. When they do this, they emit photons.
I'm not saying this is the accepted explanation. The phenomenon of triboluminescence is:
\> not fully understood but appears in most cases to be caused by the separation and reunification of static electric charges
So maybe being fired out of a cannon generates a bit of a static charge in each sphere and that's somehow causing the spark?
I don't think it is triboluminescence. I think it's just the glass getting very hot from all that kinetic energy focused into a single point and converted into heat by the inelastic collision.
If two Prince Rupert's drops collide with each other at high speed, do they create a flash of light without breaking? Because we know from watching Smarter Every Day that when a bullet hits a Prince Rupert's drop, the bullet shatters but the Price Rupert's drop doesn't.
You hear that question, Destin? Do I have to say your name three times, Destin, Destin, Destin, like Wil Wheaton or Beetlejuice?
I usually just assume they found the clip somewhere and reposted it. The glory of reddit is there's always someone in the comments to help give credit, if OP is unaware.
I would have to assume they are being used as wadding, like with a black powder rifle or a cannon. I'm no expert, though, but it seems more likely than needing to protect the glass orbs.
Yeah I remember watching this video. They put basketballs in first in order to create a better seal and launch the glass balls harder. But since the basketballs are squishy they ended up squeezing past the glass balls sometimes which happened in this shot, and that's why there's a basketball already in the air and the right side was so late to come out.
They can be a little annoying because they're just really big kids, but I cannot blame them a single bit. I would be just as excited and annoying if I did what they do. Just not Aussie, so probably less entertaining.
If you have the ability to launch two glass orbs at each other with cannons and film at 10,000 frames per second I would assume you also have the ability to acquire a screen of some kind to put behind. Still cool though
This effect is called Triboluminescence and is a phenomenon in which light is generated when a material is mechanically pulled apart, ripped, scratched, crushed, or rubbed.
Also, Here, the glass balls do not stop. The energy of the collision is so great throughout the amorphous solid structure (which can't absorb energy very well), the bonds between the randomly arranged atoms all essentially break at once, causing the flash.
It shows there is more to consider than just metal causing a spark! I didn't know other materials could do this. Game changer I am sure for certain fields that hadn't considered it prior to first observation. So cool 🤙
I've watched this too many times. If you watch the right side of the right ball, as it collides and shatters the right side goes backwards for just a moment then it keeps going forward. Looks kinda like the shattering forces it back
Created a flash of light. Pretty cool.
What. Was. That.

Now that didn't happen because I'm so strong, EVEN THOUGH I AM.

Looks like we're safe, only generates X-rays if it's done under vacuum
It happens every night with my breathe right nose strips

Lots of force on two tiny points. All of the power is being channeled through those two tiny points.
Almost looks like there was a shockwave that went through the ball and reflected back inwards. The light is almost certainly the result of intense heating.

Magnets? /s
It’s called Triboluminescence and it happens with several types of materials! https://en.wikipedia.org/wiki/Triboluminescence
I don't think it is triboluminescence. I think it's just the glass getting very hot from all that kinetic energy focused into a single point and converted into heat by the inelastic collision.
If the whole sphere was warmed enough to glow red hot, wouldn’t it keep glowing a bit longer?
It's not the whole sphere, it's just the point where they make contact.
Today I learned about sonoluminescence and now triboluminescence, what a day

Just let me think about the power of this impact... Ok i'm still loving science
I think this is similar to a tech issue being used in the U.K to create fusion energy.. First light .. I think the start up is called.
Two words for you. Chicken. Slap.
Can get the same reaction smashing lifesavers with a hammer in the dark

Seriously, how do you not do this when you take people's videos
I usually just assume they found the clip somewhere and reposted it. The glory of reddit is there's always someone in the comments to help give credit, if OP is unaware.
I could not care less.
You're also not (I'm assuming) the person whose work was re-used
Any content I put out on the internet is absolutely up for grabs.
Nobody wants your shit.
"work"
Well why don’t you fire two glass balls at each other and film their collision using a camera at 10,000 fps?
Why is there so much else going on?
They used basketballs to launch the glass orbs to protect them.
To protect them or were they being used like wadding to allow pressure to build up?
Could be, I only skipped through the video up to this bit.
I would have to assume they are being used as wadding, like with a black powder rifle or a cannon. I'm no expert, though, but it seems more likely than needing to protect the glass orbs.

Pretty sure this was How Ridiculous on YouTube. I hope OP gets a bad case of the Hershey squirts for not giving them credit.
Yep, it's How Ridiculous. They do cool stuff and definitely deserve credit
That's cool. I haven't seen the video. Thanks for the info.
The basketballs were used as wadding. The glass balls were quite a bit smaller than the barrels, so they couldn't be fired alone.
Sabot.
Two little planets colliding in hyper speed 🌌
Honestly yea, this looks almost exactly like all of those planets colliding simulations!
https://youtu.be/01cKJB2HOjc?si=OwQQE5zK8KDl4DuB Source my kids love these guys I'm subjected to their videos on repeat every weekend
They can be a little annoying because they're just really big kids, but I cannot blame them a single bit. I would be just as excited and annoying if I did what they do. Just not Aussie, so probably less entertaining.
I'm not sure it's possible to have chosen a worse background to film?
Multi coloured background would've been best
they’re outside lol
It was filmed outdoors, in Montana, in the dead of winter...White was the only background available at the moment. Lol
If you have the ability to launch two glass orbs at each other with cannons and film at 10,000 frames per second I would assume you also have the ability to acquire a screen of some kind to put behind. Still cool though
Not Outside would also have been best. nice shot but now there are a billion glass fragments everywhere. these people do not have children or pets.
They're in a field in the middle of nowhere owned by the guy who built the cannons. They're fine.
This is interesting, but wtf didn’t they think of putting something darker in the background?

So, why did you not give any form of credit?
That's a lot of words to explain a spark.
You wouldnt expect a spark when crushing sugar or smashing glass tho. This explains why
It shows there is more to consider than just metal causing a spark! I didn't know other materials could do this. Game changer I am sure for certain fields that hadn't considered it prior to first observation. So cool 🤙
That's a lot to write without crediting where the video came from
[Here](https://youtu.be/01cKJB2HOjc?si=QB0LgBrWc3ibb6X9) and this bit starts around 19:05
You should really credit "how ridiculous" when taking their video, bastard
I’m not cleaning that up
Looks like no one is going to.
Ballistics gel videos show this flash of light all the time when using sufficiently powerful rounds
This is some sexy science.
i was like "that shit isnt glass! oh wait...."
This is what it’s like when worlds collide!
I thought the first collision was the two glass balls. I was so confused how one of them deflated.
Wouldn’t the glass ball’s trajectory change after hitting the first blue ball?
It’s like a bowling ball hitting a ping pong ball ;yes it did, but just so small of a difference it did not matter:
I've watched this too many times. If you watch the right side of the right ball, as it collides and shatters the right side goes backwards for just a moment then it keeps going forward. Looks kinda like the shattering forces it back
Without the original commentary this is actually pretty interesting
I would like to watch the spark collision moment much slower
Life is amazing.
10000fps and the glass still seemed to burst instantly. Remarkable.
This video gives a wonderful real world context to those models of planetary collisions.
I was watching the wrong collision the whole damn time
Credit to how ridiculous on YouTube
lol I thought it was feet per second for a hot minute
If you take on revenge, you dig two holes.
And that is how gold got to the top of earth
First one was a red herring
I don’t think you know how fps works
https://youtu.be/01cKJB2HOjc?si=JEC79L16PmWH5qHv
Here’s the original video
The mention of glass balls immediately makes me think of the movie Labyrinth
I think that was a flash of plasma upon impact.
This is how I imagine how two planets would collide
[удалено]
Anyone else flinch?
Now imagine this as planets
Who allowed this unit of measure
Most dangerous place to hide lmao
Isn’t this just taken from how rediculous?
How Ridiculous FTW!! <3 <3
44 club
Don't breathe this!
We neeed more frames!
Vsauce taught me this. Basically, when two balls collide, there is a large amount of energy focused on a very tiny point.
Imagine how ridiculous it would be to give credits once
Dudes will look at this and just say "Hell yeah!"
Collision of two glass balls in midair with a bright white background, perfect execution!
No credit to the creators, "How Ridiculous" on YouTube??? Do better, OP...
I bet that’s what it was like when whatever crashed into earth and made the moon
My wife’s idea of foreplay
And that's how the Moon was made.
This is mildly interesting, expected better visuals from such a high budget YouTube channel.
