Kyle, love your videos, however, I have noticed a few issues with your experiment. First, your glove. The cutters were taped on and did not have the stability to keep from rotating along your fingers axis (I hope I explained that corrects. Catwoman's cutters are at her fingertips, much like a thimble, so she can put force behind the cutters by pressing her hand forward. Secondly, as Catwoman scores the glass, (assuming that it is possible to trace a circle with your fingers, I'm sure this technique takes practice), she is making a score with each finger. Each finger that follows along the score from the previous would create a deeper score and would allow her to tap through more easily than shown. not to mention would also allow each for the following tips to follow the previous tips groove, which would make the cutting pattern more accurate Third, your cutters. Although glass cutters like the one you used are designed as a wheel, Catwoman's are more of a fixed point much like a diamond tipped drill bit without helical valleys on a drill bit. Although this would cause the tip to ware faster, more pressure could be applied to a point. Finally, I understand that you used a downward force in your experiment, but that is also an odd angle to which to cut with your fingers. Its possible (not confirmed) that one could apply a greater force of pressure to cut with their fingertips if their arm was extended in a more natural direction. Much like how in the video game, she applies forward force rather than a downward cutting angle which could feel "odd". Using a glass box could provide a more accurate Just some thoughts, and could possibly result in a different result to your experiment.
I think the one additional consideration here, that your final point speaks to, is shear strength. Catwoman is superhumanly strong in the comics. Not Superman or even Spiderman strong, but she is shown to break chains with her hands and jump to rooftops and second story windows. I know Kyle is a pretty good climber, but he (and no living human) will ever duplicate Catwoman's fingertip pressure.
The fact her claws are curved also means that she can have her fingers at an angle and the point will still be perpendicular against the glass, increasing her stability and the force she can apply compared to Kyle having his fingers 90 degrees. Her claws are also firmly attached to her gloves, while Kyle's glass cutters on his glove are attached by elastic.

@@vasudevraghav2109 yeah, but we have some times in which Catwoman explained that her claws were made out of diamonds and therefore were able to better cut through glass and some other surfaces.
When you said "think like an engineer" I honestly thought you were gonna whip out a 3D-printed glove mechanism that locks two or three fingers into tracing a perfect circle
from an engineering perspective, i would have gone with a suction cup and stabilizing rod to get the good circle which would free up the effort coordinating it to instead apply more pressure. and while not as cool cinematic it has been used in cartoons and movies before, catwoman is kinda expected to be that much more skilled at this particularly task from experience and because she does it presumably with the diamond tipped claws. kyle did still prove the plausability though.
I’m an apprentice glazier and glass cutter, and this is very similar to what we do, however we use a compass-like tool with a suction cup and a glass cutter on the end to cut a perfect circle each time. We then scratch some lines within this circle, much like you did, to help assist with the breaking of the inner glass. Glass will run off wherever there is a little imperfection, and manually cutting a circle completely by hand will almost always end up in glass running off due to us simply not being able to create a perfect circle. Great video buddy 🤙
Gear: diamond-tipped nails on leather gloves. Technique: Make the circle, and then bring the nails in toward the center. Powers: Just a bit over normal human strength and dexterity. Seems legit!
Honestly it seems semi-plausible. Though I think the easier way to do this would be to use something like a high power IR laser beamed through fiber optics to your fingertip, trace your fingertip in a circle to heat a very narrow ribbon of the glass to something like 500°C then softly punch it.
Joe Murphy hahahahaha bruh power source? Heat insulation on her hand? Glass is not that easy to melt also if it does melt it won’t break because it’s an amorphous solid. But that gives me an idea theoretically if you scratch it with the diamond glove and then heat the outer rim of the circle the expansion would cause the glass to break more cleanly or spray NO2 in the Center that will give it a thermal shock and shrink and break giving you access to the sweet sweet copper
@@vasanthsreeram you don't need to melt the glass entirely, just soften it. And secondly, you wouldn't even need that much power. If your laser was focused on a sufficiently small area you could heat a very thin path though the glass, and since glass is a very poor conductor of heat, you wouldn't have to worry too much about the rest of the glass sapping the heat away.
Instead of a glove, what you want is a geometric compass to score out a perfect circle, and a suction device that can apply ramping pressure to lessen the chance that the cut portion falls inward.
I'm pretty sure a show/media has shown this to be the way it's actually done. I can't remember if they went into details but I remember that glass is just far too brittle to have the circle fall out without causing the rest of the sheet to break as well if the suction cup isn't used. Essentially, the Catwoman way of doing it is artistic license but the concept itself is valid.
You could still incorporate this into a glove - a suction cup that attached to the thumb and the glass cutter mounted to the knuckle of the middle finger. You'd have much more control from the knuckle as opposed to the tip of the finger. You'd also want a sleeve on the back of the glove that the cutter tucked into which would allow you to apply greater pressure towards the glass plane. Also, I think the key to getting a good break is to apply a very quick, but firm tap.
I think that's also the reason why the glass broke outside of the … circle. Because it wasn't a particularly good circle and had tiny corners on the outside (probably where Kyle would stop and start scoring) from where the rest of the pane broke.
@Scott Pike he must have thought of it......cause he was on 'Mythbusters: the search'..... He just wanna try catwoman stuff cause why not?..... Don't u judge my Super vill....ahem ahem..... I mean Hero for a fool
Working with a ton of glass, yes, this is how it’s done. Usually you want the circle as your piece though and not the outer part. But the concept is the same. A big reason it doesn’t work for him is the cut is so fine and he lifts the tool so he’s not getting it exact. Any overlap will have the potential to fragment out to the edge of the glass as well.
Are we seeing Kyle achieving his final form and finally becoming a full on Mythbuster ? This is totally the kind of thing they would have tried to bust !
*armaments If there ever was a YT channel nerdy enough for this kind of correction, this is it. Any and all whining about grammar/spelling nazis are hereby made invalid
The sharp corners in the "circle" make it break away from them I think that a perfect circle (like the one she makes) has a lower probability of shattering the outside glass And she has supernatural abilities which help her tap with enough force while making it seem effortless (because it is effortless for her)
Also, diamond>steel, tip>wheel, and scoring a circle five times is better than scoring it one time. In theory, of you score it enough times, you can cut through the glass.
@@ninjahombrepalito1721 so she has 5 or 10 diamonds with her on those reactable claw things always? To the thing of her being a theif that would be good as diamond is good at cutting more than just glass.
In the infrared part of the video, the glass actually behaves as a mirror, as you can see the person recording Kyle in it The question is, can we calculate an estimate of distance between this person and Kyle to know if they are social distancing using geometry? probably, but I'm a bit lazy to do it right now
Probably could, but I'm lazy. Will maybe do later. It will be something about how angular distance relates to distance and using the cellphone as a reference point.
@@NeP516 The only way I could see it working is by knowing at least the cameraman's height. Even then, the measurement would very likely be unreliable.
Yes, I was going to mention that too. Would be a much higher chance of success, as he could put all his effort into scouring, rather than trying to make the circle. I guess he could make his own with a suction cup, and a drawing compass, or similar. He could even make 2 or 3 passes to get a nice deep scour.
starshipeleven it can be done, it’s a matter of application of force. The tool just scores in a circle. How you apply the force after the scoring determines which piece(s) break(s). If working with a glass box instead of a single panel, all of the glass outside of the scoring is laterally supported, while the circle itself becomes the weakest point, and the scoring determines the break point. Hope that makes sense.
@starshipeleven Yes, but all movement is relative .... I guess you're more referring to a technique where they break off different sections of the surrounding glass, rather than all in one piece ?
Because we've done it, we've been cut by it, we've done it right, we've done it wrong. It's a fine skill to cut glass and he Kyle might as well have been throwing a brick at it in comparison (which is also something that I've done... For legal purposes)
They haven't programmed all the lab locations into the tram system yet. It beats the Elevators in Fallout 4 that will say 'Going Up' as they take you down to the "Czzzk" Floor
Love the video! I’ve been in the glazing industry for almost 10 years at this point and this is actually something we sort of learned about in school. When cutting glass, it will always attempt to relieve the pressure by following a break to the edge, that’s why you see that one line to the edge at the bottom. Making relief cuts in the center of the hole is exactly the correct thing to do in this situation to minimize the amount of pressure released towards the edge.
@@danielnicola7826 It sucked. 12 hour days, on your feet the whole time, depending on the thickness of glass either way too slow (standing doing nothing) or too fast (can't get the glass off fast enough). If you got a bad controller (person who sends the glass down the different lines) then they might send way too much glass at you, or none at all and then a whole bunch, or screw everything up and it'll all get fed to the crusher at the end of the line. I worked the cold end where we pulled it off the lines and packed it on pallettes, wrapped it up to be shipped. But I got to see the hot end. Mostly boring except when the mixture gets off or something makes the glass bad somehow. And yeah... That's most of it.
10:39 now you understand the concept, each finger is a different scoring line technically. by the time she rotates her arm, the glass has been cut several times in one motion.
Some things to note about your glove design (mechanical engineering major here) Problem: The scoring blades you used seemed to displace themselves when you applied pressure. Possible solution: If you were to use a stronger glove material (maybe something closer to Kevlar) you could (hypothetically) attach just the cutting blade onto the tips of the glove. Additionally, this type of design would allow you to design the fingers to either be fixed or only bend down into perfect locations on a circle, allowing the user to focus solely on applying pressure to the glass in question. Specifically, using Kevlar, you could go one of two routes. 1. The entire glove is Kevlar, with enough material to prevent the fingers from moving at all and keeping them in place to form the required points of a circle. 2. The glove is mostly Kevlar, but the "joints" IE the locations on your finger where you bend them would have gaps in the Kevlar with the protective material used in Kyle's glove underneath. Through design, you would allow the fingers to only be able to bend to a certain point (the location where the blades would be perfectly positioned on a circle). From there, the user could focus on applying pressure to the glass so long as they adequately clenched their hands in a way to ensure as little (if not absolutely no movement) of the fingers as possible while cutting the glass. Notes: Even through one of the above proposals, it would require a lot of practice to be able to perform this method perfectly. Just because you can't skid *your* car like they do in the movies doesn't mean it's simply impossible to do so, either through training, car design, or both.
that lightning strike on the sidewalk is something i have always wanted to see in life, to me it almost looks fake because of how perfect the like branches look and it crazy that is a great find and very rare. There was one time I was in Florida and a storm hit and we had a strike hit the ocean near the shore and I thought there maybe some glass there but there was not idk why maybe the water stopped it.

When you attempted to score the circle with the glove. You were fighting against your own body. You tried to rotate at the wrist. You needed to rotate at the shoulder. It may have worked better if you stood up and off to a slight angle, flattened your hand out ( kind of like the grip you use in rock climbing but with your fingers spread out). You would have been able to apply force in a more controlled manner. Though you may need a slight redesign of the glove.
7:37 I see that MythBusters sign, you easter-egging copycat. And I say that with love and admiration. I can't think of anyone better to carry the torch forward. I'm sure Adam and Jamie would be proud. Great video.
I really want to see this happen in more of a perfect circle where you dont have to reset the blade I think it would work much better that way. It seems like the problem was where you lifted the blade the glass broke along those lines since the scoring wasn't complete. At least that is my theory for the first couple failures. PS I wonder if diamond tipped claws would do the trick?
Scoring the glass only scores it. Which is fine for something like a straight line. However, complicated shapes need a bit of help to propagate the score mark deeper into the surface. Light tapping along the score line allows you to break out curved shapes from a pain of glass. It's why glass cutters usually have a rounded end opposite the cutter. It's also why you should tap directly on the score line.
Oh my lord, I cannot tell you how happy I was when I found out that you had made your own channel. I loved you on because science and really the channel just isn't the same anymore. Keep up the videos kyle, love ya
I worked for a hardware store. We did a cut in a circle for some customer. It wasn't easy and you have to have it set up to something allowing it to be guided in a circle. We used one of the tools we had in the shop taped it to the cutter as I recall. We didn't have a problem aside from it did take a lot of set up time unlike catwoman.
Hay Kyle can you calculate how fast your subway train is moving? 1:18 With the camera frame rate, the length of the motion blur and how fast there moving it should be possible i think...
@@kylehill An average train seat is 17.7 inches wide, or 44.958cm. We'll call it 45cm because the measurements taken aren't precise enough for three decimal places. Watching the video at 1920x1080, the seats are approximately 235px wide at the shoulders. This means that the seats are 12.2% percent of the frame, which makes the part of the train that's visible 368.85cm wide. When stepping through frame by frame, most of the background segments are exactly 1 frame wide, which is to say 368.85cm wide, and they're passing every 3 frames, or 10th of a second. 368.85 divided by 1/10 is 3688 centimetres per second. That's 36.88 metres per second, or 132.78 kilometres per hour. - I probably wasn't exactly right with the handling of significant figures, but I'm likely close enough, and it's been a while since high school. There's also bound to be some error factor due to the parallax between the back of the train and the tunnel wall, which would mean I'm underestimating the speed slightly, so I think it would be fair to say your train is moving at 135 kilimetres per hour, give or take a few percent. - I've hacked my local numbers station to broadcast my resume, properly encrypted of course. I believe you should have the requisite code books. - Edited to fix an error with the frame times.
@@kylehill hmm, NYC doors are ~3.6m and I think the blurred lines are as long as the shot itself. The door is 3cm in my screen and the shot itself is 6.2cm. Using Thales' theorem: 3cm/3.6m=6.2cm/x Then, when you multiply diagonally, the results should be the same. 3×x=3.6×6.2 3×x=22.32 x=7.44 So ok, the blur is 7.44m long. Some are a bit longer, but I'm just counting the big white ones. On my pc, I pressed "," as to count the frames. Every blur came and went in 5 frames. UA-cam stadistics tells me that the video is 24fps. Every blur is, then, moving at 7.44m/0.208s We multiply both by 4.807 (so the denominator is 1.) With this, we arrive at the result that we wanted. The blurs, assuming they are points and do not have any width, move at 35.77m/s. This isn't be ultra precise, I measured with a ruler. For reference, an average train moves at 56m/s and a bullet train moves at 88m/s. You really need to upgrade that thing. Greetings from Argentina.
@David Burgin That's actually a myth. It has to do with the way glass was made and mounted 800 years ago. Today plate glass is what is called "float glass" which makes it a lot more flat and free from imperfections. In ancient times glass was made in a much cruder fashion, and would have thicker and thinner parts. When windows were glazed back then the thicker part of each pane was put at the bottom because it made it more stable during the glazing process. Sorry to burst your bubble on that one. It's a common myth.
@@tarmaque There is a piece of glass in an university, it has been in the same position for a very long time, and over the time, it flows down (But very very slowly). The university did that as show case.
@@fahmi2186 Thank you. Glass is a solid... Not liquid. or Near liquid state. It'd have to reach high heat temperatures to "flow". Never heard of this "glass flows down cuz of gravity" myth but wow lol
If we look at the imperfect circles in the failed panes of glass, it would look like all the fractures that spread out and away from the circle were specifically at the points where the circle was most pointed and malformed. It seems to me that the forces were being directed along the scores until they ran into each other in opposing directions and then spread outward and away from there. That would make it seem as though if you had something like a compass to create a """perfect""" circle score, and then also tapped properly in the very center of that circle, the forces would be mostly equal at all points and instead of shattering the pane outwardly it would shatter along the scored line.
then a flat earther is like "but the glass that we see breaking on TV is all cgi. Have you ever broken glass? no? i thought so. Every time they try to tell us glass breaks, do you know what were seeing? lies! Lies! all glass shown breaking on the media is a hoax and to anyone who claims theyve seen glass break, you ask them how did they KNOW it was glass!!!"
I would try concentric circles of score lines so that when the break along the innermost line inevitably spreads beyond, there's another circle outside of it where the break can continue.
"As you can see I've been collecting assorted armaments and gadgetry for some time now" Underground lair? Pretty sure you're getting closer and closer to becoming a supervillain. Pretty much all you need is PRESENTATION!
9:42 a (big) problem we can see here is that it's one continuous cut but several next to each other, aannnd that means it's definitely not going to work here, because a second incision next to a first will actually strengthen the glass at this point since the stress is "evened out" more (don't quote me on the explanation, some time has passed since I learned this). To increase the probability of it working you need one (!) perfect continuous line without stopping in between.
Okay. But how about the spy movie/heist thing you sometimes see with suction cups and a glass cutting blade on a hinge/wire? Something like a Suction cup with a valve to make pressure, a ball bearing to rotate the blade on and something to attach the blade with. Then they usually also use the suction cup to help punch through and/or catch the glass.
So, the "issue" with a freehand circle, and by extension the scoring lines within the circle, is that imperfections will cause the glass to continue to crack in the direction of the fault. This effect is going to scale somewhat with impact of the force used to start the stress fracture. A more exact circle with a more gradual application of force should therefor produce the best results, and goes to explain how the several light taps of the final attempt lead to overall satisfactory results. The Catwoman method, with a well practiced hand and sufficiently sharp and hard nails would perform several lighter passes around the circle, reducing the overall need for pressure. It would also allow for a more spread out application of force which should mitigate the tendency for the glass to simply shatter. I kind of want to see the glove attempted again, but with some manner of ring to keep the cutters aligned. I imagine that might actually lead to some good results and feel much easier as well.
If you only wanted to test whether you could cut a circle in glass (implied by your surprise around 13:10), then you simply needed to look up "glass circle cutter". They've existed for ages; it is basically any circle-drawing tool except with a glass cutter instead of a drawing implement. If you wanted to test Catwoman's method specifically, then you needed something that comes to a point instead of a regular wheel cutter.
Thanks for watching my swarming nerdlings. This was a fun and frustrating one.
Would it be easier to break if you make scores in the shape of an octagon then score in the middle?
I know it seems unconventional to pay for, but given catwoman had a steady flow of money's.

And in using them against thicker glass for Skyscrapers, I wouldnt think a conventional glass cutter,even diamond tipped,would be any use on such thickness of glass

Also if the glass isn't under the same constraints as the type being used in displays.

You'd also want a sleeve on the back of the glove that the cutter tucked into which would allow you to apply greater pressure towards the glass plane. Also, I think the key to getting a good break is to apply a very quick, but firm tap.
I think that's also the reason why the glass broke outside of the … circle. Because it wasn't a particularly good circle and had tiny corners on the outside (probably where Kyle would stop and start scoring) from where the rest of the pane broke.
@Scott Pike he must have thought of it......cause he was on 'Mythbusters: the search'.....
He just wanna try catwoman stuff cause why not?.....
Don't u judge my Super vill....ahem ahem..... I mean Hero for a fool
Working with a ton of glass, yes, this is how it’s done. Usually you want the circle as your piece though and not the outer part. But the concept is the same. A big reason it doesn’t work for him is the cut is so fine and he lifts the tool so he’s not getting it exact. Any overlap will have the potential to fragment out to the edge of the glass as well.
Are we seeing Kyle achieving his final form and finally becoming a full on Mythbuster ? This is totally the kind of thing they would have tried to bust !

The sharp corners in the "circle" make it break away from them
I think that a perfect circle (like the one she makes) has a lower probability of shattering the outside glass
And she has supernatural abilities which help her tap with enough force while making it seem effortless (because it is effortless for her)
I scrolled down just to say this about the circle as well 😁
Also with the glass cutting point are on the tips of her fingers like actual cat claw so they aren't connected to long awkward handles
Also, diamond>steel, tip>wheel, and scoring a circle five times is better than scoring it one time. In theory, of you score it enough times, you can cut through the glass.
Also has supernatural abilities including agility n coordination. So a perfect or nearly perfect circle is plausible for her
@@ninjahombrepalito1721 so she has 5 or 10 diamonds with her on those reactable claw things always?
To the thing of her being a theif that would be good as diamond is good at cutting more than just glass.

@@q9968 It was not a question of wether they live together or not. The question is what distance apart they are given the information in that scene.
@@NeP516 The only way I could see it working is by knowing at least the cameraman's height. Even then, the measurement would very likely be unreliable.
So a glass cutter is like a tiny pizza cutter?
I've seen special cutter that make a perfect circles in some movies.
Yes, I was going to mention that too. Would be a much higher chance of success, as he could put all his effort into scouring, rather than trying to make the circle. I guess he could make his own with a suction cup, and a drawing compass, or similar. He could even make 2 or 3 passes to get a nice deep scour.
starshipeleven it can be done, it’s a matter of application of force. The tool just scores in a circle. How you apply the force after the scoring determines which piece(s) break(s). If working with a glass box instead of a single panel, all of the glass outside of the scoring is laterally supported, while the circle itself becomes the weakest point, and the scoring determines the break point. Hope that makes sense.
@@make.and.believe Maybe if he clamped it instead of just balancing it then it might have worked better.
First time I saw one of those was in Hudson Hawk. Seriously underrated movie.
@starshipeleven Yes, but all movement is relative .... I guess you're more referring to a technique where they break off different sections of the surrounding glass, rather than all in one piece ?

Misdirection
Love the video! I’ve been in the glazing industry for almost 10 years at this point and this is actually something we sort of learned about in school. When cutting glass, it will always attempt to relieve the pressure by following a break to the edge, that’s why you see that one line to the edge at the bottom. Making relief cuts in the center of the hole is exactly the correct thing to do in this situation to minimize the amount of pressure released towards the edge.
Kyle: "Do Not Attempt"
My bosses at my glass factory job (that I don't work at anymore): "... What the f*** man? Cut that bad glass off the line!"
How is it like to work in a glass factory? Im curious.
@@danielnicola7826 It sucked. 12 hour days, on your feet the whole time, depending on the thickness of glass either way too slow (standing doing nothing) or too fast (can't get the glass off fast enough).
If you got a bad controller (person who sends the glass down the different lines) then they might send way too much glass at you, or none at all and then a whole bunch, or screw everything up and it'll all get fed to the crusher at the end of the line.
I worked the cold end where we pulled it off the lines and packed it on pallettes, wrapped it up to be shipped. But I got to see the hot end. Mostly boring except when the mixture gets off or something makes the glass bad somehow.
And yeah... That's most of it.

Shh, that's the top secret project to give A.R.I.A. a human-like body in order to help out more at The Facility.
Some things to note about your glove design (mechanical engineering major here)
Problem:
The scoring blades you used seemed to displace themselves when you applied pressure.
Possible solution:
If you were to use a stronger glove material (maybe something closer to Kevlar) you could (hypothetically) attach just the cutting blade onto the tips of the glove. Additionally, this type of design would allow you to design the fingers to either be fixed or only bend down into perfect locations on a circle, allowing the user to focus solely on applying pressure to the glass in question.
Specifically, using Kevlar, you could go one of two routes.
1. The entire glove is Kevlar, with enough material to prevent the fingers from moving at all and keeping them in place to form the required points of a circle.
2. The glove is mostly Kevlar, but the "joints" IE the locations on your finger where you bend them would have gaps in the Kevlar with the protective material used in Kyle's glove underneath. Through design, you would allow the fingers to only be able to bend to a certain point (the location where the blades would be perfectly positioned on a circle). From there, the user could focus on applying pressure to the glass so long as they adequately clenched their hands in a way to ensure as little (if not absolutely no movement) of the fingers as possible while cutting the glass.
Notes:
Even through one of the above proposals, it would require a lot of practice to be able to perform this method perfectly. Just because you can't skid *your* car like they do in the movies doesn't mean it's simply impossible to do so, either through training, car design, or both.
that lightning strike on the sidewalk is something i have always wanted to see in life, to me it almost looks fake because of how perfect the like branches look and it crazy that is a great find and very rare. There was one time I was in Florida and a storm hit and we had a strike hit the ocean near the shore and I thought there maybe some glass there but there was not idk why maybe the water stopped it.

@@christianheichel hmm.... A disease that forced all of us to be isolated in a confined area... Its strangely ironic right
When you attempted to score the circle with the glove. You were fighting against your own body. You tried to rotate at the wrist. You needed to rotate at the shoulder. It may have worked better if you stood up and off to a slight angle, flattened your hand out ( kind of like the grip you use in rock climbing but with your fingers spread out). You would have been able to apply force in a more controlled manner. Though you may need a slight redesign of the glove.

At work, we dismantled some old electric breaker bars that were being replaced. We bought a nice holiday dinner with the scrap copper.
I really want to see this happen in more of a perfect circle where you dont have to reset the blade I think it would work much better that way. It seems like the problem was where you lifted the blade the glass broke along those lines since the scoring wasn't complete. At least that is my theory for the first couple failures.
PS I wonder if diamond tipped claws would do the trick?
I am pretty sure in one of the episodes of the Adam West batman series it revealed her claws were indeed diamonds, yes showing my age here

Scoring the glass only scores it. Which is fine for something like a straight line. However, complicated shapes need a bit of help to propagate the score mark deeper into the surface. Light tapping along the score line allows you to break out curved shapes from a pain of glass. It's why glass cutters usually have a rounded end opposite the cutter. It's also why you should tap directly on the score line.

I worked for a hardware store. We did a cut in a circle for some customer. It wasn't easy and you have to have it set up to something allowing it to be guided in a circle.

@@kylehill
An average train seat is 17.7 inches wide, or 44.958cm. We'll call it 45cm because the measurements taken aren't precise enough for three decimal places.
Watching the video at 1920x1080, the seats are approximately 235px wide at the shoulders. This means that the seats are 12.2% percent of the frame, which makes the part of the train that's visible 368.85cm wide.
When stepping through frame by frame, most of the background segments are exactly 1 frame wide, which is to say 368.85cm wide, and they're passing every 3 frames, or 10th of a second.
368.85 divided by 1/10 is 3688 centimetres per second.
That's 36.88 metres per second, or 132.78 kilometres per hour.
-
I probably wasn't exactly right with the handling of significant figures, but I'm likely close enough, and it's been a while since high school.
There's also bound to be some error factor due to the parallax between the back of the train and the tunnel wall, which would mean I'm underestimating the speed slightly, so I think it would be fair to say your train is moving at 135 kilimetres per hour, give or take a few percent.

@@kylehill hmm, NYC doors are ~3.6m and I think the blurred lines are as long as the shot itself. The door is 3cm in my screen and the shot itself is 6.2cm.
Using Thales' theorem:
3cm/3.6m=6.2cm/x
Then, when you multiply diagonally, the results should be the same.
3×x=3.6×6.2
3×x=22.32
x=7.44
So ok, the blur is 7.44m long. Some are a bit longer, but I'm just counting the big white ones.
On my pc, I pressed "," as to count the frames. Every blur came and went in 5 frames. UA-cam stadistics tells me that the video is 24fps.
Every blur is, then, moving at
7.44m/0.208s
We multiply both by 4.807 (so the denominator is 1.) With this, we arrive at the result that we wanted. The blurs, assuming they are points and do not have any width, move at 35.77m/s. This isn't be ultra precise, I measured with a ruler.
For reference, an average train moves at 56m/s and a bullet train moves at 88m/s. You really need to upgrade that thing. Greetings from Argentina.

"...but you don't wanna completely shatter this crystalline structure."
Well, actually glass is amorphous solid aka non-crystalline.
@David Burgin That's actually a myth. It has to do with the way glass was made and mounted 800 years ago. Today plate glass is what is called "float glass" which makes it a lot more flat and free from imperfections. In ancient times glass was made in a much cruder fashion, and would have thicker and thinner parts. When windows were glazed back then the thicker part of each pane was put at the bottom because it made it more stable during the glazing process. Sorry to burst your bubble on that one. It's a common myth.

UNEXPECTED LASERSWORD!
I'd imagine the tips of catwomans gloves are diamond. the ease with which she does this implies something much harder than steel.
If we look at the imperfect circles in the failed panes of glass, it would look like all the fractures that spread out and away from the circle were specifically at the points where the circle was most pointed and malformed. It seems to me that the forces were being directed along the scores until they ran into each other in opposing directions and then spread outward and away from there.
That would make it seem as though if you had something like a compass to create a """perfect""" circle score, and then also tapped properly in the very center of that circle, the forces would be mostly equal at all points and instead of shattering the pane outwardly it would shatter along the scored line.

9:42 a (big) problem we can see here is that it's one continuous cut but several next to each other, aannnd that means it's definitely not going to work here, because a second incision next to a first will actually strengthen the glass at this point since the stress is "evened out" more (don't quote me on the explanation, some time has passed since I learned this).
To increase the probability of it working you need one (!) perfect continuous line without stopping in between.

Okay. But how about the spy movie/heist thing you sometimes see with suction cups and a glass cutting blade on a hinge/wire? Something like a Suction cup with a valve to make pressure, a ball bearing to rotate the blade on and something to attach the blade with. Then they usually also use the suction cup to help punch through and/or catch the glass.
Evil. Super. Villain.

8:18 "want some candy? .."
So, the "issue" with a freehand circle, and by extension the scoring lines within the circle, is that imperfections will cause the glass to continue to crack in the direction of the fault. This effect is going to scale somewhat with impact of the force used to start the stress fracture. A more exact circle with a more gradual application of force should therefor produce the best results, and goes to explain how the several light taps of the final attempt lead to overall satisfactory results.
The Catwoman method, with a well practiced hand and sufficiently sharp and hard nails would perform several lighter passes around the circle, reducing the overall need for pressure. It would also allow for a more spread out application of force which should mitigate the tendency for the glass to simply shatter. I kind of want to see the glove attempted again, but with some manner of ring to keep the cutters aligned. I imagine that might actually lead to some good results and feel much easier as well.
If you only wanted to test whether you could cut a circle in glass (implied by your surprise around 13:10), then you simply needed to look up "glass circle cutter". They've existed for ages; it is basically any circle-drawing tool except with a glass cutter instead of a drawing implement. If you wanted to test Catwoman's method specifically, then you needed something that comes to a point instead of a regular wheel cutter.
