I see a lot of you want me to break the tube and film it on a high speed camera; That's not what I was going for in fact I was trying very hard to keep it from exploding. Also the volume of CO2 is low so I dont imagine the explosion will be all that impressive; But I guess I can try it and see what happens. ;)
Cody'sLab it not that we want to see that exactly. but a thought a normal test tube would not hold the pressure right would be cheaper why not make a smaller tube the same way then rather than cover in sand film it turning into co2 then building pressure and either exploding or turning into liquid then you could shoot it with a bb or something from a safe distance...
What exactly do you think would happen? Would it resemble a prince Rupert drop since there is a lot of internal pressure?
Also, why not try to reproduce this and dissolve some hydrogen into the gas? Attach a nozzle and you have a hydrogen fuel. :) Isn't that the current hydrogen fuel limitation?
Cody, I would say keep your first one as a 'keep sake'. If you really want to make one go boom, you can do better than a little tube! :D Keep up the great work man, this is one of my new favorites.
Or just reheat the end of the tube. Either the pressure is enough to blow the top off and spatter hot glass everywhere, or the gas expands the top until equilibrium is reached and you're left with an odd shaped glass wand.
i was pretty sure u would smash it at the end. Its not like you cant make a new one, hehehe.
"cardboard bucket"
"wooden box"
keep tryin youll get it
I came down here looking for this. Thank you kind sir
Hes not exactly wrong.......what's cardboard made out of?? Wood pulp. Lol
@@protectoroffaith exactly why i didn't comment. Well...and the fact that the video is three years old as of now. Though, this comment makes it irrelevant in a way.
"super dangerous, high pressure it can explode".

The stupidest experiment I ever did was sealing dry ice into a thick-walled glass soy-sauce bottle. (I was young and INCREDIBLY stupid.) It certainly liquefied, but then I realized that I had a potential hand grenade that I couldn't depressurize. I put it in the sink and tried to cover it with water, so there would be something to dampen the explosion if the bottle broke. Well, I made the stupid mistake of turning on the hot tap to fill the sink, and sure enough, about a second after I stepped back, there was an enormous bang and a lot of vapor filling my kitchen. If I'd been leaning over the sink, I'd be blind or dead.
Your way seems much more sensible.
At least you were smart enough to recognize the problem you'd created and take some caution. I'm kinda impressed honestly, especially considering similar stories I've heard.
Hobo Sullivan lol wut
@DikoMan if you have an unstable handgranate in your hands cheking the temperature isnt your highest priority
Have the sink survived?
Did the sink break?
1:06 - "Just to cake sure"
I do that sometimes, you're thinking of another word, but switch at the last second, but mix them together

I do that too haha
*says “bucket” and “wooden box” to the same carboard box
0:40 "bucket" 1:42 "wooden box"
No I do never do it as should I be about to, my other selves always help me out...
And really, who isn't thinking about cake at random times throughout the day?
0:40 that's a very cardboard looking bucket
ReabowRotors Or wooden box...
lol
ReabowRotors 1.40 thats one nice wooden box
Bart Meijer Well, the cellulose part is there, I guess... ;P
Get the water out of the town well with that.
Cody should call up the SloMo Guys and film a high-speed drop test of this thing
YUSSS!
Wouldn't be too exciting. The glass would shatter ofc but the liquid would just evaporate into invisible CO2.
112BALAGE112 but the 72 atm pressure means it will explode very violently; I want to see this too.
The CO2 would actually freeze solid again. A sudden drop in pressure causes a drastic decrease in thermal energy. Some of it would become gas and take energy away leaving pieces of solid CO2.
D Hawthorne wrong comment bud
They say only two things will survive the apocalypse: cockroaches and Cody'sLab.
And at this rate Cody could build a mini nuclear reactor from the cockroaches.
Unless there's a cyanide spill, then only Cody would survive.

Wrong. This nerd wouldn't survive a day.
Being book smart isn't real knowledge.
He has quite a lot of real knowledge.
The whole time I'm holding my breath praying that it doesn't blow his hand off omg
Do a detonation test with the SlowMoGuys. Setup a rig where the tube is on the ground and a hammer strikes it, or it falls from a short distance. In slow motion, if the tube is truly under something close to 1,070PSI, the result of the escaping CO2 returning to homeostasis should be brilliant.
George Martin camera would definetly break
Lenz Visser Visser they would put a panel between the camera and the tube
i get nervous putting it under more then 30 psi. ive seen pieces implode under just 15 psi of vac. this is just stupid.
Put the tube on a hot plate to heat it up rather than hitting it with a hammer,
@@thedoctor2102 hair dryer...or heat lamp..you dont want to touch it to anything, you dont want a point of heat or cold that can shock it. normally wouldnt matter,,but this thing is on the edge of exploding.
its like nitroglycerin
Make it explode in a safe environment ! I'm curious about what would happen (would the gas expand instantly, or start boiling/forming dry ice ?)
BTW, watching this little "CO2 storm" at the end is soooo soothing and exciting. I wish I could buy one of those thing, I'd play with it for hours. I'm sure watching this strange liquid behavior wouldn't get old.
Mr Nobody your English is suck not is good.
I'm not sure what you're trying to prove here, but indeed my English if far from perfect. But I'm French and it's not my native language, so I guess it's kind of understandable, right ?
+Mr Nobody There are a couple small grammar mistakes, and you misspelled "gas". Nothing major, and it's easy to understand. At a quick glance you can't tell that your native language isn't English.
It's all wrong, almost incomprehensible.
+Sam C I can read it just fine, I don't get why you don't understand it
That glass is impressive. I expected the thermal shock to shatter it on sealing.
Borosilicate glass is used for that exact reason - it expands and contracts very little with temperature, so it is unlikely to shatter upon thermal shock.
SonOfFurzehatt Thanks for the explanation.
+SonOfFurzehatt Yeah, it sounds weird, but Glass may be one of the greatest things 'invented' by humans.
Glass is discovered. Glass making technologies invented.
Borosilicate is still prone to crack under thermal shock though. For high temperature quenching (for instance 1000 dC -> -196 dC), quartz glass is preferred to an almost zero coefficient of thermal expansion
I just realized cody has more than 800k subs! Can't wait for 1 million! :)
Umer Ahmad fff
same
Umer Ahmad Oh that's crazy. I don't know how many subs he had when I joined but it was when nighthawkinlight mentioned cody
I've been here since 80k subs. It's awesome to see him climbing up there!
Yeah, he's gained most of his subs within the last year or so. The first video I ever watched of his was him opening a lock with nitro (NG). I have no idea when that was uploaded, but started watching his videos on a regular basis when he started doing a lot of beekeeping stuff. So glad you've made it this far Cody. These subs will help you to keep affording interesting things to provide us with some awesome demonstrations.
that last shot was beautiful. it was like its own ecosystem in a tube.
Except for the 500'C bit.

Profit!!
Sweet! Thanks for the link to my channel, as well. I was looking for quartz tubes that were rated for high pressures to contain SC CO2, but I agree that "unrated" tubes which happen to be strong enough are OK, as long as the user anticipates an explosion. McMaster (and others) sell sight gauge tubes for steam boilers, which are rated up to 600 psi, I think.
No problem! its one of my favorite videos on RUclips!
I've had a few tubes burst, I think the bursting pressure of thees is 1300-1600psi fortunately they contain only about 5ml of gas so the explosion isn't that bad, I had one go off in my hand and it hurt but didn't blow a finger off or anything. I've been learning quite a lot about the compressibility of super critical gasses and I think I'll make another video about that and blowing one up on high speed. :)
I'm wondering if it's possible introduce a non-reactive gas into the tube with dry ice before sealing. Something that adds contrast to make it easier to observe the fluid dynamics.
Cody'sLab you said wooden box haha
Welcome to Hydraulic Press Channel today we will be crushing supercritical CO- BANG
it may atakat any time so we must DEAL with it.
VAT THE FAK
Titan-Eren It is very dangerous we must deal with it
cody make another one and throw it
Kye W i would like to see that too. with so much pressure its got to be quite a big bang!
^This. I would like to know just how dangerous it is to handle / potential damage to look out for. It would be a good way to determine how much safety gear is enough. Plus, explosions. I mean you know you want to....
I used to do that with small glass coke bottles and chlorine. Had an old quarry nearby that had a nice big bolder in the bottom next to the high wall. Id hide behind it and lob my glass grenades out into the open and the glass fragments would hit the wall behind me and shatter. I wanted to try experimenting to see how powerful the explosion were but I had to stop due to the massive blasts drawing attention to my activities. The glass flew over 50 meters easily. The gloves Cody was wearing are completely useless and if he wants to experiment, try exploding one of those tubes in a glove and see how it fairs.
Use a styrofoam box, paint it black inside. Place a holder of any type in the box to hold the tube. Place a thick tempered glass over the box, film the explosion from above the glass.
After the explosion, focus on the shrapnel found in the box, and the holes that they created in the walls of the box, how large and deep are they. The black surface and white mass of styrofoam would make the result very easy to observe!
Did you commission that avatar for yourself? Or is it from someone else? :O

Who needs gods when you have science? :)
A. Lampman I thought of the same thing.
Bait.
+Bruhcoli, without humans there is no science, god is irrelevant here :P.
I discovered this channel a couple months ago and I have watched every video since. I love your channel thanks for making high quality informative videos.
I'm impressed with how well you melted the glass with what looked like a normal daily MAP torch.
When substarndard equipment is all you have, its what you get good at using.
I was impressed the cutters worked as well as they did to seal it- I was thinking hmm is that really the tool for the job? Yep. Nicely done Cody! XD
You're on my Emergency Engineer team :)
Tin-snips become crimpers when used with hot glass. lol
That's going to be more than a firecracker if it lets go: just gas at 70 bar is bad enough, but you'll have extra expansion from the liquid turning into a gas. I work with supercritical CO2 and when a tube 1/4" around by 2" was tested to failure in a water tank it cracked (but did not penetrate) 1/4" Plexiglas (after travelling through 6" of water).
When sealing tube like that with a torch, I like to attach a vacuum pump to the top with a piece of silicone tubing. Then I heat about an inch or so down, the vacuum pulls the tube shut when it gets to the melting point. And it prevents the air inside from expanding and blowing out the end you are trying to seal.
445supermag that is actually brilliant
Lmao watched him break that shit in his hand and you overreacting... comical really.....bih.....
0:41 Cody, I'm pretty sure that's a box. Not a bucket.
1:42 Also that's a cardboard box, not a wooden box.
AWSMDEWD Why is it not a bucket? And how is it not wooden?
Prove it
Well it's definitely wood.... it has cellulose...
and it's also definitely a bucket, it's... a container!
He is extremely nervous at the moment of just creating liquid CO2 cut him some slack.
Ahahaha silly goose
"wooden box" well i mean youre not wrong
Mason S It's a cellulose object...?
Bart Meijer SCIENCE! ^___^
Mason S
At one point it was a bucket, I'm sure with the impending thoughts of extreme high pressures in a glass cylinder, Cody can be forgiven.
When is contained dry-ice, the bucket was rectangular and brown, later when filled with water it was cylindrical and white. That's what I call a phase-change :)
My Materials Engineering professor uses some of your videos in class for explanations of various material properties. Thank you for enlightening us with obscure experiments.
This was my first video of Cody. I have seen a lot more since then. Thanks Cody for good work
Very cool! I'm starting to get nervous about the long-term survival of the Cody....
I guess it's super critical I watch this video
OB-One get out
OB-One, ignore Giovanni, he's just being super-critical about your comment.

Only goggles? I'd be wearing a full on face mask with neck protection!
This is Cody, he drinks cyanide...
Cuts will heal, blindness wont, and I dont mind getting cut all that much.
This guy handles bees without gloves or masks... Sorry but a couple hundred of those stings and trust me you wont care about a cut or 5. They are nothing compared to what he has dealt with. If it was to break it would start at the top were it is weakest and he keeps it from his face as well. LoL..... ive seen WAY more dangerous stuff that everyday parents let people do because they don't understand what they are doing.
cmsjr123 I just don't see the comparison between bees and high velocity shards of glass flying at my jugular. Cuts are one thing, punctured veins are another. There is no way to know where the glass could break, there could be imperfections anywhere, but that is a moot point.The amount of pressure in there could send the glass at very high speeds. I would just rather not be picking small pieces of glass out my face and neck if I had the option, that is all.
the irony is cody is probably the safer of the youtube chemists. the backyard scientist makes me cringes when i see him using hot or highly corrosive material, splaching it around his garden in short and a hawain shirt. i feal the minimum safety is at least coton trousers.
Dang it Cody!!!! I was waiting the whole video for that thing to POP!!! had me on edge. LOL
This little project is beyond cool. Thanks Cody!
This is one of the coolest videos you've done. Awesome.
i worked at a paintball shop for 3 years, filling small tanks for the guns, from the big ones outweighing me.... i all ways tried to imagine a clear tank, and what it would look like inside, so its interesting to see this, especially the little storm at the end...... it would be awesome to find a safer container to make a bunch out of, for people to play with.
If only transparent aluminum was a real thing.

"wooden box"
Cody, that's a cardboard box. Your brain is a wonderful, strange thing.
posysajrazdwatrzy he was probably scared of it exploding...
twoja stara, don't you just hate it when boxxes explode?
Eric Fixalot hate when it happen.
+Peter S I hope you're being sarcastic, Cody showed us his blood tests proving he doens't have heavy metal poisoning.
that looked like it was evaporating and forming liquid at the same time. That was soo awesome!
this literally helped me understand gas laws, and phase changes.
subbed
Cody.... get it together... first you called it a bucket, and now its a wooden box! Come on man!
Don't mock the Genius when he his brain is doing 10000000 things at once and trying not to get blown up by a glass vase while talking to a camera.
That's clearly a cardboard box...
No, you're just dumb. It's obviously a cardboard bucket
well... wood-> cardboard, same material, so i guess he's not wrong?
wood pulp equals cardboard equals wooden box
that's not a bucket Cody, is a box
Zabuza Momochi its also not wood
RocksDa RS it is? Papers r made out of wood
Sanz but the real question is if wood is made out of paper
RocksDa RS no wood is made out two trees having sex.
Sanz mommy-tree, daddy-tree, were do baby-trees come from?
well son . . .
6:14 If Cody won't store it in the house, that's gotta be pretty damn dangerous XD
Lewis Massie if he will just keep it in the freezer, it SHOULD be fine right? As long as he keeps the temperature changing down to 'freezing' gradual, the glass shouldn't shatter from thermal shock, and the CO2 would be at lower pressure... Or everything I have been taught is a lie, the world is a dodecahedron, and the moon exploded 10 years ago, and the moon landings were as secret experiment to build a 500 Megaton nuclear Fusion weapon in the Moon's deep interior, actually FUNDED by the Soviets. If the latter streak is true, then I need to get a new textbook, and dye my hair the brightest neon yellow I can find
Chadwick Posey Depending on it's form, Uranium is quite safe. It's not the horrible death-trap you think it is. Just don't go ingesting it, because I believe that can cause problems.
Uranium is quite safe.

Yeah, and I have the world's best fire retardant, That doesn't mean i'm gonna light myself on fire to prove it.
Store it in liquid nitrogen... you'd actually create a vacuum in there above the dry ice snow...
I liked being separated from this experiment by thousands of miles. Thanks for the great videos Cody.
This is definitely one of the coolest videos you have made!
I could barely watch this. The fear of this exploding with borosilicate shrapnel ... just terrifying!
Povl Kvols I agree
There are two ways to teach physics/chemistry: a boring one (as my teacher does) and yours.
No risk, no fun :-D
Teachers could make videos like this one on their own and show it in class to avoid the danger. Most teachers are just lazy assholes who couldn't care less about being interesting.
What did you actually learn from this ?
If you're not interested in actually understanding what happens and how and why it happens, it will be a boring subject for you. Here, you're not excited by "learning" since you're not learning anything whatsoever, or maybie one or two very basic pieces of information. You're just watching someone else learn a lot by performing experiments himself, and you enjoy the cool stuff that happens along the way.
But quit lying to yourself about learning anything on videos like these. This kind of experiment is certainly a great teaching tool if accompanied by actual learning about what happens and how to describe it in exact physical terms, with models, etc.... but apart from that it's just a cool video that gets all it's dimensions when you know something of in this case fluid dynamics etc...
I wish Cody was active on youtube when I was in school.
I got good grades in everything BUT "physics" (Fysik in Swedish).
Now i'm hooked on "how does it work, why does it do that"..
STAY IN SCHOOL KIDS!
I'm not sure I would go that far with teachers as being lazy. They may have all chosen to be teachers for different reasons. Many probably eventually burn out after doing it for so long and being run down by the average student (i.e. not interested, goofing off, and only there because they had to be). Kind of hard to continuously be motivated when you are always getting little, negative, or no feedback. No, I'm not a teacher, just reflecting on the ones I've had both good and bad and my observations over the years. Long after all my education from of K-12 and college, I still remember all the ones who were influential and those who were not.
Wow, I can’t stop laughing at calling a cardboard box a “bucket” and a “wooden box”. My god, make it stop! Even reading this comment is making me laugh.
Hi Cody
My name is Ibrahim I have been watching your videos for a long time and every time you keep me wonder how life is around us.
Keep doing what you do.
All love from Saudi Arabia
I love when you absolutely geek out about things. It just shows how legitimate you are about your work and your love for what you do. Keep up the amazing work and and content or I will have to quit life.
That storm cloud it's AMAZING!! i would like to see what kind of damage this exploding could cause...
mpcabete last time i read someone say shads instead of shards was in boston!
what would happen if you added food coloring before sealing the tube? would it mix in the liquid?
actually it may be able to mix with the gas! Thiss is something I will have to try.
yey another video soon then :D
Cody'sLab You should try with methylene blue!
There's a thumbs up just waiting for that video dude. =D
CO2 is an organic solvent, right? Are there organic compounds that change color when dissolved? It would be cool to watch that happen.
Place gel around it then heat it so it explodes and see what kind of damage it causes
This channel's amazing. This guy just single handedly manipulated the states of matter in one glass tube.
The last shot was very cool. Like you are watching another planets atmosphere. The CO2 forming clouds and cycling through rain and vapor multiple times before stabilizing. Great experiment!
I saw "extreme danger" and "supercritical" and I thought, "Oh Cody's having a fun day"
Hey Cody, i would highly suggest you purchase a black felt screen. it would make the presentations way more visible
first you called it a bucket then a wooden box
Because things change ))
I noticed the same thing, lol.
He's too smart that he couldn't think straight
Technically speaking card board is made from trees so it could be considered a wooden box.
Carbo foam extrusion
I was wondering about the future of this, and glanced over and saw the video "Breaking The CO2 Tube at 6,000fps". Sweet!!
Yes! I was hoping somebody would make a video about this! I didn't think it'd be possible.
This was cool. You need to do more with liquid oxygen. I love the blue color.
And this is liqu.. BANG
Dropping a match in liquid oxygen looks awesome
I'm subscribing now since you said you are going to see what would happen if it explodes, so don't disappoint, lol. I also hope to see loads more cool stuff you can do in the name science, maybe have fun with SF6 or something like that
I plan to film it tomorrow and post it monday-ish.
Shoot it with a 22cal ;)
that wnat from a square bucket to a wood box..... man i am keeping all the cardboard boxes i see cause they are magic now......
Rofl. Was thinking the same thing! xD
I knew they were multi-purpose but I didn't know cardboard boxes were also multi-personality
I am so happy to see you channel growing like this.
by far some of the coolest stuff i've seen...keep up the good work
That bucket looks a cardboard box.
Oh.. nevermind, it's wooden cardboard.
James Neace lol that's exactly what I thought too... haha silly Cody, that's a box not a bucket!
its not a bucket, its a wood box obviously.
Amazing the glass can take it. I thought borosilicate glass was tempered for use in industrial and lab apparatus - reheating it would probably weaken it?
Glass is surprisingly strong. Flint glass is usually hardened like that, not sure about borosilicate but this wasn't tempered.
Cody'sLab good boro glass is designed to handle the higher heats. and is resistant to physical shock.
its not tempering that makes it strong, the boron gives it a lower expansion coefficient making it less susceptible to generating mechanical stresses in the glass.
Snocrash Holy fuck! It's you! I get so excited when I see A t
yter I like comment on a another yter I like's vid :D
You guys are all correct. :) Only when you melt and form the glass you are putting stress into it. In a perfect world, and if it was a pipe or something, you would anneal it in a kiln to relieve that stress. If you have access to a polarizing filter(s) you can see the sress lines in glass. You can still thermal-shock borosilicate. It's just better at it than soft glass.
"Wooden box"
cardboard is made out of wood so he ain't wrong ;)
Paragon643 and humans are water because we are 60% water.
Yeah and a stack of printer paper is also just a stack of wood
He also called it a bucket @:42.
I loved the raining at the end... this is one of your most interesting videos, thanks
Nice demonstration. That I will never do at home.
In case of explosion, it is difficult to remove glass shards from the eyes!
Thank you for this video!
Two chemists are saying goodbyes to one another:
Chemist 1: See ya!
Chemist 2: CO2
What a scientist comedy...,,😁
Cody: "I'll transfer this over into this WOODEN BOX here-"
Me: Cody that's cardboard...
Cardboard is derived from trees.
Cardboard boxes are wooden 🤔
As a Glassblower works with Boro you should've just pinched it when you were going to seal it it would've been fine
I've always thought that the rough surface would make it weaker but that would be a lot easier.
Cody'sLab Cody, Can I suggest an idea for a video? there is this dotted image of red and blue dots and on the phone, if yoi scroll fast, you see all purple dots. I was wondering that if the phone pixels itself mixes the colors or will your eyes mix them. so I was wondering if you can do a slowmotion of this.

Wow really interesting to get an insight into those phase changes Cody, and the physical behaviour of a low density liquid under a high density gas. Awesome.
definitely the coolest actual science you've shown us. thanks for the hard work Cody
I am a scientific/industrial glassblower by trade with 20 yrs experience. When I saw you handling the "loaded" tube, I cringed! I have seen first-hand what glass can do when it fractures under pressure. Gloves and glasses may have helped, but what about your body? Glass is so sharp you could take a small shard to your body that could travel several inches under the flesh - heart, lungs, intestines, man parts, etc. Please be careful doing these experiments!
Yeah, this was dumb
Is there any gas that has a higher density than a liquid? So the liquid would float?
(That can be at normal atmospheri pressure)
No, there is a gap about 2 orders of magnitude wide between gases and liquids.
Tungsten hexaflouride is the most dense gas at STP - 1.3 g/l. Liquid hydrogen is the least dense liquid (I think) at STP - 71 g/l.
So no, we won't see liquid floating on gas any time soon :-(.
Ok so I'm sure its possible, but difficult... I'm looking at a table of critical densities and it seems CO2 is the highest (of common gasses at reasonable temperatures) but its still only .46g/cm^3 perhaps if I doubled the pressure I could push it up to the .8g/cm needed to float NaK.
So... Compressibility factor of supercriticial CO2 is lower than I first thought. I would need to at least quintuple the pressure...
Hey Cody! Since you have some gold and access to a vacuum pump, could you try cold welding? I think it would be a very interesting video. You could polish flat pieces of gold then put them inside the chamber and apply force through a mechanism (maybe drop one on top of another). I'm sure you can figure it out. Please do it dude I love your vids!
Thank you - this is one of your most impressive and interesting experiments. You could suspend the glass tube inside a clear acrylic housing to prevent the glass receiving direct shocks, and to protect the handler from exploding glass shrapnel.
Oh man i built a chamber out of schedual 80 pipe and forged end caps and then heated it till i got to 4000psi. I had a safty factor of 6 but was still nervous as hell lol you are a brave man. Love your videos
Was that thing at the beginning supposed to have spelt "Cody's Lab"?
yes
Loyteg
That's a very informative reply, thanks.
Ameto I think it's in braile.
Oxygen probably. He is probably using magnets underneath to create such effect. Nitrogen is not diamagnetic enough to do so, oxygen however is.
nice
film in super slowmotion when you crush it
1:10 "just to cake sure" I died of laughter
Nice Demo ! Must've taken considerable time & effort. Thanks
Very creative idea Cody. Well executed process and good photos too. I was impressed. Thanks for making the vid and sharing with us.
quit teasing us cody. we all want to see this tube explode.
Amazing !! I understand that this pressure is highly Dangerous if released, but how much Dangerous is it ? Maybe you could rig an experiment to show with balistic gel / high speed camera what it could do if it releases its energy, maybe you could do that with The King Of Random ?
Have a nice day =)
flo ri
I would like to see him throw one
Please do it!! Both for us to understand how dangerous it is and for the fun of it! =)
flo ri king of random is a hopeless tool
YES!!! BLOW IT THE FUCK UP!!!!!!!!!
probs not that bad. paintball canisters hold 4500 psi
What are you using the glass tubes for? Also, where can I buy some!
p.s. borosilicate shrapnel would be a nightmare for surgeons to remove from your body and would cost you your trip to mars, be careful!
Man, that looks crazy. Clouds and rain in a glass tube...
Thank you for being so nuts. I wouldn't dare to do so. Please take care (of not cover) and be safe.
This is one of the coolest things I’ve seen Cody do. So AWESOME!
*taps against concrete* BOOM, there goes your hand!
Erik Lindgren yeah about that, why would it explode if it touched the concrete? Temperature shock?
Meminjo it could crack simply by moving it agaimst the concrete too fast
Condensed Magic Essence.
Cody you will make my day if you reply to this comment
Make his day pls he deserves it !
I saw that comment about fifty times. How about doing something to deserve what you want for once huh ?
Adrien Perié i posted it as a joke didnt think it would get this much attention
I am so glad I found your channel Cody
Hey Cody. Although relatively simple, this is one of your most visually appealing videos. The CO2 reacts so strangely in that state. Very cool! Thanks for all the great videos.
That is so cool. But, you should smash it.
For science.
Cody, you're becoming reckless. That's incredibly dangerous. When sealing volatiles that boil below room temperature in tubes, you need to cool them down using something cooler than themselves and you NEVER pinch the top. You want 1 atmosphere of pressure at all time, as the weld cools down, and you want a nonstressed weld. Pinching it, especially with a cold metal, will cause strain.
Also, dumping sand on the tube could've caused an explosion. Sand is much harder than borosilicate glass and any contact will score it. That can trigger breaking when stressed by over 70 atmospheres of pressure differential.
That tube isn't thick enough, either. It might've held together in warm water, but glass is a moody thing. I'd destroy the tube, safely.
word
Experimentation is reckless.
this is Cody ... he could find a way to make electricity out of 2 paper clips rubbing together. although yeah i agree with what you said a stressed seal can break all to easily.
Lajos Winkler all that you've stated may be true, but he can do what he wants. He obviously respected the power of it. I think he did this for fun. He would need special tools and materials to do it the way you call safe. That cost money.
No, it does not take special tools and materials to do it safely. Flameworkers do it all the time. It's about patience and skill.
I don't understand the "he can do what he wants". What are you argumenting with that claim? Did I call the police? No. I just don't want him to get injured, or others to adopt his mistakes. We live in a time when information travels instantly over the planet. One error can thus cause a lot of damage.
Me: "Why tf didn't he blow it up at the end!? I gotta comment.."
*scrolls down to comments*
*Sees "Breaking the CO2 tube in 6000fps" in related videos.*
:D
To me, this is one of the coolest science demos I've ever seen. Supercritical fluids are such weird things.
Almost 100,000,000 million views on your channel!! Thats awesome, congrats :)
what would happend if you would throw this tube at the wall
i think the glas would shatter and the co2 would vaporise instantly
You'd have glass sharpnel in ur eyes and could see nothing
*BOOM*
What if the wall decides to fight back? Then you'll be sorry!
I came here because it said extreme danger
Best prank: Step 1: Put a pillow on a chair ( as thin as you can get for maximum shrapnel penetration.) Step 2: Put the tube under a pillow and place a small rock or a hard object under the tube to create levrage. Step 3: Enjoy!
Thats not a prank but rather attempted murder.
just don't make a video about it, then you'd be golden.
well its a creative way of doing it
Not if you say "It was just a Prank Bro!"
***** Cody, you and I both know: Anything you call a prank is a prank, especially on youtube.
"Aye sarge looks like we got a kid putting crack vials together by the highway overthere."
"No thats just our local Cody, We don't interfere he's the EMT's problem"
one of the coolest things I've ever seen, nice experiment
