Hi Natalia!
I misunderstood this as Cody attempting to dissolve himself and pass through said pane of glass
same here
It is Cody after all, such an experiment wouldn’t be too surprising
@@AndrewNajash hence the misunderstanding
You're not the only one.
Me too...
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
On the bright side, he didn't tell you.
Don't tell Hams they can get HF in a huge jug.
How dangerous is it?
It couls melt your skin very rapidly.
Only 48% HF though. I have toilet bowl cleaner that is 25% HF... still dangerous to touch, dangerous fumes, but not quite as brutal as pure stuff.
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
It might just implode anyway
i really wanna see this now
Nope it will explode

@@givrally7634 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.
Cody seems to be planning a heist.
Indeed apparently on an secret alien base on Mars in order to steal martian pine tree seeds for the ranch.
Shhhhh he doesn't need another visit from the feds lol
A very, very slow one judging how slow that acid eats through the glass.
No money in a demonetised channel still gotta buy bread somehow...
is this unusual?
that thing with the glass tube and a steel bolt is actually a pretty good representation of how prestressed concrete works
Good shout
It's basically exactly what happens. Just replacing the concrete with glass. It's the same technique, as you said
Spancrete is manufactured with tension bars through it which do exactly this.
If your not familiar, it's used in parking garages or buildings where concrete needs to span distances and hold weight. They actually create an arch (like a small rainbow) so as weight is added to the top it actually gets stronger.
Biggest limiting factor is the steel bars holding it together.
I recognized the same setup from *I think* Practical Engineering's video on concrete reinforcement.
@@The_Razielim that's what I thought of, too.
Experienced chemists: "I don't want anything to do with HF."
Cody: "Hold my protective equipment"
Is it the thing they used in Breaking Bad? XD
Why is that?
@@realsirpurr because it is super dangerous
Scott Xerri it is capable of dissolving; human flesh, human bone, ceramic, steel, other metals, GLASS, wood, stone. What you saw here was only a very dilute mixture.
After HF exposure, fluoride ions penetrates human tissue and do all manner of awful things. One splash could potentially kill you if it gets on your skin. The fumes can damage your lungs. The fluoride can displace calcium preferentially and cause your heart to stop. Sometimes it causes persistent pain for years deep inside your body. So there are both immediate hazards (similar to other acids) medium term hazards related to calcium/fluoride balance issues, and long term hazards (chronic pain for the rest of your life).
While the acid experiment was unsuccessful, the explanations and demonstrations were very helpful. I now know how tempered glass works, thank you Cody!
Absolutely! --- Now I just wonder: Does tempered steel work the same way? If so, I've learned a lot today!
@@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.
@@timhuester7721 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...

*puts on ear protection to pop a balloon.*
this is why we watch Cody
Safty first
Always work in protected mode. :)
@@426shelby426 safety first: washes mouth out with mercury
If he didn't, somebody would complain!
I wonder if he was wearing the chain mail too.
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
@@m0w0ss 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!
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
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
As a second attempt this is way better. The first attempt felt rushed and kinda like "um okay?" This feels like a much better video. And for those not on patreon cody usually puts a lot of work into these videos. We will sometimes get first drafts and its good other times it will be 3 tries.
I took 2 weeks to film...
@@jesseking4815 So?
So it wasnt rushed it was just not entertaining results
@@jesseking4815 it still felt rushed man. There wasn't an explanation of what was going on or really anything. It was basically just him putting acid on the glass then coming back twice once to change the acid another to see it was broken. That to me feels rushed. Sure 2 weeks of filming but once he got the footage he rushed to upload the bit he had. Which I appreciate having in the first place but I was trying to give feedback and appreciate the extra work he did.
x9x9x9x9x9 I kinda like a rushed Cody feel, it reminds me of his earlier videos
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.
Read that as "I demand success using lasers..."
Can you actually get all the way through?
@@harbl2479 Yeah, the material was about 1mm thick so I used the laser to get most of the way through (which took forever) then I was able to crack it along the seam. It really shoudn't have worked but we weren't complaining.
@@brandonberchtold9484 check it with some polarized sheets. we use credit card sized sheets on both sides of the glass if a piece of glass is in question after tempering to check around holes or cutouts. trick we use at the factory for the more expensive custom orders.
@@d32th Didn't have any polarized sheets on hand at the time but that would have been really interesting to see the stresses induced by the cutting process! I'll keep that in mind if I ever need to do something similar in the future.
This video just needs a cut to Jerry rig everything saying "glass is glass, and glass breaks"
Just the thing i was looking for
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
@@piisfun Is it still up? I didn't see that one
Michael Johnson it was a joke x3
@@Mikemk_ 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.
All you need is a steel sphere.
Ask Elon.
Random Electronics and Displays it didn’t go through tho so maybe 2 steel spheres
Why do your comment is 8 hours ago but my notification of this video is only 45 minute ago ?
Fuck elon musk, he abuses his workers and makes false accusations.
MARINA AAA go spread that bullshit somewhere else
MARINA AAA fuck you
Cody: It disolved about 3/4
Also Cody measuring how much was dissolved: exactly 3/4
Yep 4.76 / 1.2 = 3.96666666667
Jerry Whidby he measured 1.19, not 1.2
4.76/1.19=4.0
@@tinldw ahaha you're right. I just used the number he called out. I didn't notice the reading on the caliper.
Trust but verify your own intuition, is good practice
Next logical question: "Can you melt through tempered glass with thermite?" :)
You can melt tempered glass with a blow torch kind of device. It's how lots of the weird glassware for chemistry is made.
actually, I think that if you melt the glass, it might work, so while it sounds insane.... might actually work better...
If you heat the glass the whole thing up then you will take the temper out of the glass and you could drill the glass and then possible re temper it. However a blow torch would only break the glass.
I would love to see that that be awesome.
@@maxximumb It shatters unless heated and cooled very slowly.
2:12 "I'm gonna tight dizz nuts." Ha! Gott'em
Lulz nice one!
Welven!
I like this one better.
better than what?
That one, duh
Maybe better than if he dissolve himself through a glass?
@@charlottestewart1851 There was a previous version of this video posted to patreon. And this video was posted to patreon before being made public on TH-cam.
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?
@Beamer - Are you saying the hole went all the way through the windshield? That should not happen, because windshields are supposed to be _laminated glass,_ while side windows are tempered glass.
@@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.
@@johnmatthewson6733 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.
@@johnmatthewson6733 - TH-cam'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.
This is the type of "Cody's Lab I like best. The glass under compression was super cool.
TLDW: Cody used his superpowers and dissolved through a wall, appearing on the other side.
3:40 SHRIMP IN A BOX THREE CONFIRMED!
So tempered glass is basically a flat prince rupert's drop
@@Turnip_ Yes. Kind of implied in the comment there bud. Except when you hear the words "tempered glass" you dont think prince rupert's drop... you think of that flat sheet of glass typically found in doors, windows, and refrigerators. That's the point I'm getting at here.
Oh yeah, of course!
Jeff Klaubo it looked like you were asking a question / observing something new for you. turnip answered / confirmed it.
Jeff Klaubo It’s the other way around. Prince Rupert’s drop is a blob of tempered glass.
no the prince ruperts drop is tempered glass boi
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
@@Sp00kq 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.
Love your videos Cody, I know you’ve had a hard year but your looking like your old self and throwing out the videos. I really hope you have the best 2020 ever. You deserve it.
cool way to demonstrate how and why pretensed rebar in concrete works
I noticed that, too. Concrete will crack and shatter the same way the glass tube did if the tension is released.
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
@@quinokin8954 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
@@dantethunderstone2118 Good point. Good science is built on 95% failure, 5% intuitive guessing
Great job Cody! Glad to see u still doing cool stuff. When i need a break from my own life I appreciate your vids. I can hit play and forget my problems. Thank you!
I've never seen a explanation this easy to follow! So fascinating, Cody great work!
Remember the old times when Cody was running around with just dynamite?
@Angelo That was the joke ;)
I feel like Cody's planning a bank heist
Sorry I can’t like it’s at 69
I'm glad to see you getting back to sciencing. Tis what i subscribed for. Keep answering the questions only those with abstract thought patterns will ask.
Cody I love your vids, you always make my day and educate my in the process,keep it up!
HAPPY THANKSGIVING CODY!
I once had a window that was always angry and never nice to me, they must have used bad-tempered glass.......... :P
Yes
I can only imagine the pane you had to endure ;)
i had a window like that too. it pretended to like me, but i could see right through it.
Ugh what a pane
Cease function
I love this kind of random topic video! Thank you Cody!
Great video Cody. Good explanation of the phenomenon, worthwhile hypothesis, and a great test setup
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.
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.
That looks like the harbor freight 55 lb anvil to me
That explanation at the beginning was brilliant! Thanks Cody!
Awesome idea! Really glad you're still coming up with new ones, man.
That was a very intuitive explanation of tempered glass. Thank you.
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).
this is by far the best explanation for tempered glass that ive witnessed, meaning i actually understood whats going on. demonstrations are just awesome!
Your science videos are always interesting and oddly mesmerizing. Keep them up, dude!
as a chemist i have a huge amount of respect for everyone working with HF.
i never thought etching will working. its like cutting a rubber band unter tension. it will always snap apart because of tension. there cannot be a rubberband with tension and a whole right through it
The rubber bands I've seen usually come pre fitted with a hole through them ;)
They can though like in the middle of it will just make the band easyer to rip as bans are not brittle like glass and have no cracks to propagate and break it
Are you german?
@@abdelrahmananbar6286 is who German
HF really man. You don't have to risk that just for us viewers cody.
Keep making videos Cody been looking for new content and finally saw this one been following you for about four years now and greatly enjoy seeing yours to this day.
Great video. You look much better than a year ago and you sound much more motivated. I remember that you told about your mental issue a while ago and I'm happy to see you in better condition now. Stay save!
"Glass is glass, and glass breaks..."
Jerry Rig Everything 😉😉😉
Said the wise bald man
Now the same with a Prince Rupert‘s drop.
Love all of your videos. At 4:06 I got a glimpse of Cody's Lab 50 years from now. Will stay subscribed to find out for sure.
This was a fascinating experiment and explanation!
Next you should try disolving a Prince Rupert's drop in HF.
Finally, the Chad Cody is here.
Fantastic video Cody! This is the best explanation of, and demonstration of, tempering I have ever seen. Fantastic! I hope some physics teachers out there find and use this video!
i love your videos so much cody. this was really cool !
*gouges the glass*
"I introduce tiny micro-cracks"
It's time for the acid...
And now I dissolve through glass
Cody thank you for making this video. Been watching since less then 100k subs!
I find your chemistry/physics (broadly defined) videos like this one to be the most interesting kinds of videos that you do.
My all time favorite video you did was the one on frobscottle. Not only is the subject and result fascinating, but the video shows your thinking and approach to the question.
And I appreciate that you post the fails as well as the successes.
Keep the videos coming!
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'm curious how far you could get into a Prince Rupert's Drop with HF before it explodes
Really interesting video! Loving it! Keep it up cody!!!
Thank you for doing this. It obviously takes time, energy, resources and intelligence to produce these exceptionally clearly communicated videos. BIG thanks.
"well, i guess it's time for the acid."
I have always been amazed at how fast tempered glass breaks. Slow mo Guys made that video and estimated that the cracks moved through the glass at around 4,750 feet per second
That sounds about right. That is approaching the speed of sound through glass.
Generally all cracks propagate in the speed of sound in that material
@@St0RM33 They'd propagate faster if they could but the speed of sound slows them down.
Cody, you always deliver. Thank you.
Hey Cody I've been watching you for a very very long time your videos are the best thank you for making all this wonderful content😄
Should've put a camera while dissolving to catch the explosion :D
2:13 hah got eem!
The explanation in the beginning was truly fantastic, I could completely understand what you were talking about. Not many people have that talent
Thanks for giving us all this interesting content and I hope you and yours have a Happy Thanksgiving!
So I guess tempered glass is built kind of like a giant Rupert's drop.
Not kind of. Rupert's drops are tempered glass
Just semi spherical version making them stonger as sphears well dont have any corners or weak points
Pretty much. The stresses in the glass depend on the glass staying in the form it was when it was tempered. Any change beyond a certain point and KABOOM.
I'm left wondering if it would be possible to etch a very small hole all the way through, although to be honest I can't see how you'd keep the acid in a blob (scientific term) small enough.
Well not exactly. You see, the faster you cool it, the more brittle it gets. Also, after initial hardening, they heat the glass again with moderate temperatures, to regulate hardness. This way they make it as hard as it needs to be.
@@xxxggthyf Acid is an isotropic etchant. You want an anisotropic etchant, like plasma etch.
Take a shot for every time he said glass, then you'll probably be able to figure out the next video he's going to upload
This opened up my understanding of materials. Great video.
Fascinating, as always. Thank you.
Im gonna scratch my piece of glass : "thrill"
Awwww damn, I thought you were gonna try and dissolve yourself,thru the glass
This was a very interesting video to watch thanks cody now I understand glass alot better. I'm gonna share this with my friends.
One of your best vids in a while. Keep it up.
- Cody, what are you going to tighten again?
- DEEZ NUTS
Could you try "drilling" a hole in a way that introduces a "wall" to the perimeter of the hole to hold back the pressure of the glass? Sort of like how they would dig wells and line the hole with stones.
The problem is the glass pulling outwards away from the original hole, not pushing in, also how would that even be possible?
Really love your chemistry content Cody, thanks.
That was a really great explanation of how tempered glass works. Thanks so much for being an amazing teacher.
Can you dissolve through the Cybertruck’s glass?
I hope everyone appreciates Cody wearing gloves during these experiments. Glass cuts and HF burns are both very serious in different ways.
How are glass cuts "very serious"? I'd like you to tell my stained glass instructor that because when I brought gloves she said we'd be doing it w/o gloves. And she was right.
@@johnpossum556 they can cause nerve damage. I'm guessing you weren't in any sort of situation where you put any significant torque on glass. get over yourself
@@notgood38 OK, tough guy knowitall. Actually you put a lot of torque on glass when you cut it. And if you knew Cody by now you've probably figured out he uses the finest safety measures that the mountains provide him with. LOL!
As always, wonderful video!
I miss videos like these from you, Cody. Nothing comfier than this stuff. Great video.
Too bad, nice try though. I would like to try this with a Laser (high power cw and a pulsed system for ablation)
A (relatively!) low power laser might actually work since it should anneal the glass before melting a hole in it, thereby releasing the internal tension.
However, a high power pulsed laser isn't likely to do any better since the heating ends up localized to a thin layer on the surface, leaving the center under tension just as if you were drilling or dissolving a hole.
@@Keldor314 I'm pretty sure high powered lqzers would work as they would vaperise a small layer of glass preventing the glasss from cracking and it may even heat up the surrounding glass sort of sealing it causing no tension to be released like when you make a vial
@@oliverboi High power pulsed lasers actually barely heat the surroundings of their target at all. This is partly because the pulses are extremely short. They vaporize a thin layer of molecules, which take the heat away with them as they disperse. After this, the laser pulse is already over, so the next layer stays cold.
Avoiding cracking might not be good enough to prevent shattering. The problem is that even without the outer layer, the inner glass is being stretched by the intact glass around it, much like the membrane of a drum. As you thin it down, eventually it reaches a point where it's just too weak to withstand the tension and it will snap violently, causing the entire pane to shatter. Any cracks will make it fail much sooner, of course.
What you need is some way to release the tension inside the area you want to remove without shattering the glass in the process. Annealing is the obvious method, but maybe there are other ways?
High powered laser pulses do impart physical shock to an object, certainly enough to shatter the tempered glass. Ablating the glass or melting it will still not work because of the difference between the internal and external stresses baked into the tempered glass. There is no way of relieving these stresses without heating the complete pane and then cooling very gradually to normalise the glass.
JerryRigEverything be like: Glass is glass, and glass breaks!
This was the BEST tempering explanation I've seen, congrats Cody!
Long time viewer.
Thank you, Code.
Big fan. Happy Thanksgiving brother.
When he said "I'm going to tighten these nuts" and "I'm going to loosen this nut" I started laughing out loud like a twelve year old.
