I test to see if I can successfully make a hole in tempered glass without shattering it by using chemicals instead of abrasives.

You should try to remove tail from prince rupert's drops with the acid. With out the tail those would be super hard to destroy.
Same thing will happen
I wanna see this
practical engineering: steel reinforced concrete demo
cody's lab: steel reinforced glass tube demo
broke:
woke:
We've got Chemist vs Engineer, and Engineer vs Mathematician. I'm eagerly waiting for Chemist vs Mathematician.
@Givrally I got a notification for your comment, so I went and re-watched this video because it's so good.
@w0ttheh3ll Haha, I do that a lot.
Experienced chemists: "I don't want anything to do with HF."
Cody: "Hold my protective equipment"
What does HF Stand For?
Will Snyder Hydrofluroic
Yeah, but he used HCl...
Memento Mori Thank You XD
it can kill your nerf, its also can dissolve glass that why its dangerouse
There is NileReds professional chemistry stuff, then theres Cody whose like "So I was making explosives in my garage..."
Nurdrage also fits but his upload schedule is rather sporadic so nile it is
While the acid experiment was unsuccessful, the explanations and demonstrations were very helpful. I now know how tempered glass works, thank you Cody!
@Martin Verrisin Tempered steel is actually more fragile but also harder than non tempered Steel. But steel is still a different material, thus in matter of flexibility and breakability it's on an other chart than glass.
@Tim Huester Of course, completely different, but the core being under tension and outside under compression is probably the same?
- So, it would make sense to make it harder.
- Steel is usually quite flexible, completely unlike glass, so it makes sense, its' more brittle, but.... I guess tempered glass is actually more flexible? If that's the case, that would probably be a big difference...
I'd argue the experiment was successful! The video's title was a hypothesis. We proved the hypothesis was incorrect (for this method). That IS success in science!
@SciSky True. Science makes successes into failures, and failures into successes, so you never know how to feel. :D
... although: in this case we still don't know if it's impossible, or if it just didn't work this one time...
That why an experiment never fails, you always learn
The first minutes are one helluva great demonstration on structural materials science and compound materials
ikr I feel like this could and should be used in schools and universities
Interesting video Cody, this is how I inadvertently did this: Our car’s reverse mirror suddenly fell off the front window screen. So with two part Araldite and a couple of pieces of tape, I stuck it back on the front prestressed glass. After about 6 months; it again fell off but, this time had taken with it the glass – there was a neat square hole (the exact size of the mirror support bracket), through the screen! Otherwise the screen was perfect :) I suspected that constant thermal cycling between the glass and the Araldite (differing coefficients), had made benign minuscule cracks through the glass - that eventually joined up! If waiting isn’t a problem – this is a neat and safe way of cutting shapes into this type of glass :) Perhaps you can find a method of speeding this up?
@YodaWhat Thank you for your thoughtful reply. Yes your absolutely correct and yes - it was the front windshield. I assume the minuscule cracks formed penetrated through the sandwiched film + perhaps the weight of the mirror assembly with the car moving - did the rest? Being a Ford Fiesta, it also probably wasn't the most expensive of glass ;)
It's not thermal cycling. Epoxy has a much lower stiffness than the glass so the thermal mismatch is mostly accommodated by strain in the epoxy. What you saw is caused by the several % shrinkage of the epoxy when it cures. This pulls the surface of the glass into tension around the periphery of the epoxy which causes preexisting microcracks to extend slowly under the combined action of the tensile stress and corrosion of the crack tip by atmospheric moisture leading to delayed failure. This phenomenon is called stress corrosion cracking or subcritical crack propagation. It can be sped up by heat and higher humidity, but no dramatically. Failure of the glass causes a flake of glass to be detached but still attached to the epoxy. This leaves a conchoidal (scallop shaped) pit in the glass. I believe some years ago this was used to make a sort of non-see through glass by completely covering the glass with epoxy so causing these conchoidal fractures all over the glass surface.
@John Matthewson Superb explanation. This happened about 30 years ago and has always left me pondering what the mechanism might be - it was such a neat square hole. It's very easy to grab the only adhesive to hand but, it's worth taking the time to think - before using it :) It was an expensive lesson! I liked your non-see through glass info bit. Have a healthy and prosperous new year.
@John Matthewson - Youtube's algorithm beat you to it (for me) several days ago with the glue explanation, but showed it being done with old-fashioned hide glue. Evidently it works much faster because it shrinks much more.
@John Matthewson yes, this is why a crack grows in windshields unless you tie the surfaces together again with resin
This video just needs a cut to Jerry rig everything saying "glass is glass, and glass breaks"
It took way toooooooooo long to find this coment
Just the thing i was looking for
Cody seems to be planning a heist.
Because some safes and anti theft mechanisms use glass panes as a hard lock feature, which makes it even harder to open after broken into. 😏
Raid Fort Knox when?
What could be possibly need to steal? He can already make everything
@Crysis_ Pyscho u mean area 51? who needs gold anyway
He just needs more raw materials, elements and chemicals , also more compounds 😆
TLDW: Cody used his superpowers and dissolved through a wall, appearing on the other side.
can we take into notice how Cody lifted that anvil Like it was nothing
Absolute unit
I don't think that anvil is any significant weight to lift with both arms. Yeah, they are heavy, but an average person should have no issue lifting that anvil. An average male can dead lift around 160lb - 200lb. Someone who is reasonably built (but not massive) should be lifting closer to 300lb and over. This anvil isn't impressive.
@Jack W Google it. I just did and to be honest, I was pretty spot on, well, near enough to most the Web results for average deadlift weight for untrained average male. Remember this was average male and not you specifically.
Next logical question: "Can you melt through tempered glass with thermite?" :)
I would love to see that that be awesome.
@Maxx B It shatters unless heated and cooled very slowly.
@Maxx B chemistry glassware is most likely borosilicate glass PYREX , which is not the same as the new bs cookware being sold as pyrex which is soda-lime glass. You'll notice PYREX is clear and pyrex has a green tint to it.
Answer - no. Heat stress will cause it to shatter in seconds. But it would look amazing. And send pieces of molten metal flying in all directions. That's pretty \m/.
@Gary Vance Thermite is too uncontrolled and fast, but shouldn't a (carefully applied) blowtorch locally remove the tempering before it melts through?
I tried cutting a piece of glass, after it exploded all over the shop, then I remembered it was out of a storm door (tempered).
Cody: Dissolving Glass
Me: Oh god please don't tell me he has a huge jug of HF
Cody: Pulls out a jug of HF
@BoxHeaD It will not dissolve flesh if that's what you mean. But sure, it will mean the affected body part will need to be removed - so can then "open it up and have a look about" :)
@1024 Concentrated or fused alkaline hydroxydes can also, for instance fused NaOH or very concentrated solutions of it
@catherine Ramouillet you learn something every day... Wow
@Jero Toro are your sure it is HF in your bathroom cleaner and not HCl?
David Tanner Where did he say that?
"Glass is glass, and glass breaks..."
Jerry Rig Everything 😉😉😉
Said the wise bald man
2018 Cody: I'm going to build a nuclear reactor!
2019 Cody: I need to punch a hole in glass
Its clearly all part of the plan
Well, he did get in trouble with the federal government over the refining Uranium video...
@Piisfun Is it still up? I didn't see that one
Michael Johnson it was a joke x3
@Michael Johnson I don't think so. But I do think mirrors of it might still be available, though I haven't looked in awhile (a quick check didn't yield any results). I did see a mirror of the video in which he exploded half a kilo of copper thermite in a sealed pipe (which I think got Cody a strike on his channel since even he admitted, IN THE VIDEO, that it was basically a pipe bomb). But that's gone now too. Nobody's allowed to have any fun anymore. Thanks Youboob.
Remember the old times when Cody was running around with just dynamite?
@Angelo That was the joke ;)
So tempered glass is formed simerly to a prince rupert's drop.
Exactly.
You are correct my fri- wait a minute... I want to see Cody try dissolving through a prince ruperts drop
@PhoenixUltraMotive it would probably go the same way as this did, prince ruperts drops are able to withstand extreme pressure and that's it. It doesn't really have much difference to tempered glass in way of its physical properties.
Prince Rupert's drops are actually how they discovered tempered glass in the first place.
Next you should try disolving a Prince Rupert's drop in HF.
Love the pause at 3:13 when he considers if he messed the explanation up. Then decides that he can salvage it.
But he shouldn´t have mentioned the outside contracting since that´s not relevant.
gouges the glass
"I introduce tiny micro-cracks"
You sounded so disappointed. That was cool ! Remember, an experiment is a success if we learn something from it, not if we get the expected result.
But, he did expect the result to be the glass breaking... xD
@Quino Kin XD true... he wasn't surprised, so he wasn't excited.
If you get the expected result it’s not an experiment it’s a demonstration
@Dante Thunderstone Good point. Good science is built on 95% failure, 5% intuitive guessing
All you need is a steel sphere.
Ask Elon.
@Bob Bobbertson OK byeeeeeeee
@Celtic Dude I'm not an Elon fan if you'd like to know, I was referring to Cody and his channel.
I'm very confused to be honest about Elon's new vehicle and really would not want one if I had that spare cash????? 🤮
@Low Flying Potato Well there is a video of them testing the glass beforehand the presentation. The glass blocked the metal ball just fine.
Saddow BannedbyGoogle plus they literally hit the doors with sledgehammers beforehand so the base would’ve cracked anyway
Yo guys calling elon trash and shit when he made electric cars to stop global warming and he's making reusable rockets so that u only make them once, and you pay less charging your car then with refining your car with gas and his cars are exremly fast for such low price
I'm curious how far you could get into a Prince Rupert's Drop with HF before it explodes
So basically St Rupert's Drops are just beads of extremely tempered glass.
Yep :) tempered glass is extremely fragile on the corners, one tap and it will shatter :)
I remember AvE trying it too, I think it was a Pyrex bowl or something, he used a much milder method than just a wet diamond hole drill, but still wasn't able to do it.
2:46 legend says that hes still tired from trying to loosen up his nuts
I would recommend not dissolving, Cody. I’d miss your uploads.
I have faith he could reconstitute himself though
im a better egg than you
@Riley even if he gets dissolved..he will get reprecipitated pretty quickly.
Meh, Shinji did it and managed to come back from it more than once so it can't be that bad!
Instead of a cap, could you add tension around the acid site to keep the glass together
Theory: As soon as the acid gets to the middle portion of the glass, all it takes is the tiniest crack for the whole piece to spontaneously shatter. Even if you were to somehow get the glass to not break with acid, you'd have a timebomb on your hands.
"What the hell, that's some thick glass"... HOLY SHIT a yank with his calipers set to milometers!
Boy that glass sure had a temper when trying to dissolve it lol
that thing with the glass tube and a steel bolt is actually a pretty good representation of how prestressed concrete works
@The Razielim that's what I thought of, too.
I was in the industry for 10 years and that was my first thought as well.
Indeed
@Tom Haflinger same cause i watched that an hour ago (practical engineering/concrete video)
Cody compressed the glass. For the steel you need to stretch it from both sides. The exactly opposite of this but the general idea is the same.
It's time for the acid...
And now I dissolve through glass
this is by far the best explanation for tempered glass that ive witnessed, meaning i actually understood whats going on. demonstrations are just awesome!
When I worked in a glazing shop in Arkansas we used to have to use a torch to cut glass especially if it's tempered a acetylene torch
Oh boy... Cody's breakin' out the Bone Hurting Juice!
Im gonna scratch my piece of glass : "thrill"
Really enjoyed this video Cody!!! I can't wait to see what you have next.. im always amazed to see what kind of experiment you will come up with next, what happened to the bees wax projects??? I remember you had so much of it at one time?
I actually thought you'll use heat, silly me, you're chemist!
Awesome idea! Really glad you're still coming up with new ones, man.
The dissolved surface looked quite rough. I was expecting it to be relatively smooth. I suppose this could have contributed to the breaking.
I always wanted to see someone play with HF. Now I can sleep tonight knowing my dream came true.
I could feel his disappointment through my screen!
Well I never thought of that. Even though it didn’t work, thanks for trying it out and letting us know.
I've had decent success laser cutting through tempered glass slides. Using fast and light cuts vaporizes a very small layer without introducing too much heat into the rest of the glass.
If you use lasers though is th glass not being melted shut as it cuts meaning the pressure inside is not being changed
@demonitized fun The laser did 20 - 40 passes with time between for the glass to cool. The passes were quite light so it only vaporized a small layer each time as opposed to melting its way through.
@Tiny lock picks Inc. if you don't have polarised sunglasses, the disposable 3D movie glasses are perfect. Can just pop out the lenses for cheap polarised sheets
@Kain Yusanagi look up how to cut tempered glass. It will tell you that to cut tempered it must be annealed first. I'm a glass worker bud. Glass and steel have very different properties but the annealing process is essentially the same. What you are talking about would be called glass blowing, or glass shaping that is heating it up to be workable.
@chris101ward If you're a glassworker I'll eat my hat, because you don't seem to understand the basics of what annealing is, even when it's described in detail to you, and the tempering process is also detailed to you, and they're wildly different. Lemme see if this time it'll get through your head:
Annealing is the process of reheating to relax the crystalline structure of the material of the stresses from working it, the letting it slow-cool from a high heat to room temperature over hours, to not introduce stress into the structure of the product. Tempering is the process of quick-quenching (using air with glass instead of a liquid like water or oil so you don't introduce temperature differential fractures to the piece) a piece to change the crystalline structure of the piece through specific stresses and temperature changes, and for glass specifically it's used only on a single side of the pane to introduce directional compression much the same as Cody discussed in the video.
Crazy I was thinking "wow I haven't seen anything new from cody in a wile" then boom new video!
0:04 well with hydrofluoric acid anythings possible :)
Never thought about this, thank you.
Daniel A - 2019-11-28
I misunderstood this as Cody attempting to dissolve himself and pass through said pane of glass
Flunkyvs Lacky - 2020-08-18
Yup
Tim K. - 2020-10-23
I watched it again after some months and still misunderstood it like that again....
