Its so surreal, I remember the first video of him I saw. It was him making slime. But to younger me, it was magic. He has been a large part of my life and it pains me every time I remember he's no longer with us. His death truly feels like I have lost a loved one. He was more than just a content creator to many of us, he was family. We miss you Grant. RIP :(
Cody, you know what I love about your channel? Not only is it your detailed educational content throughout your videos and the pure entertainment of watching chemistry experiments that aren't boring, but you didn't sell out and go with an over-produced, I'm cool, YT channel. It's just pure chemistry from a dude living out in the country, just being the true Cody. Much respect man. Great job all around.
Cody, a tip from a former borosilicate lamp worker: heat below where you want it to seal so it melts inwards and is thicker and able to withstand higher pressures. the way you showed yourself sealing it left a very thin seal. also the slower the temperature rise and cool the stronger the crystal structure. heat the top few inches to a couple hundred degrees and then seal above it and coat it with carbon from the torch to help slow it's cool.
When you make the seals, try to make them as round as possible, (e.g. test tube like bottom) not a pointy tip, and they will be stronger at high pressure. On the first seal gather some extra glass and while still hot blow into the open end to produce a smooth rounded bottom. Of course you cannot do this with the final seal, but make every effort to make it rounded, not pointy. Also, even though Pyrex has a low thermal expansion it will still develop stresses as it cool. To minimize this, after you make the seal, you should flame anneal by heating the seal in a cooler flame. On a butane torch this can be done by restricting (not totally) the air inlets to produce a yellow carbon rich flame. The idea is to uniformly heat the sealed area below the softening point of the glass to relieve the stresses. Then immediately bury your seal glass in some vermiculite so the glass cools slowly. This will (can) make a better result and stronger seal. That said, I am impressed with your 700+ psi ampules. Cheers, Mark Old Lab Glassblower *******************************************
please don't call borosilicate glass pyrex. Pyrex is a brand and not all Pyrex is borosilicate. The misnomer can be quite dangerous if somebody heats shocks non thermal resistance pyrex
the lab glass is boro but it would be bad if someone thought that the kitchenware was. to make matters worse before a certain date the kitchenware was borosillicate.
Cody, I really appreciate how you actually explain the chemistry and the science behind what you do on your channel. A lot of channels that do "science" experiments never explain what is actually going on at a molecular level or why their reactions are taking place. Thanks for what you do. Its awesome!
your channel is growing so fast! And you deserve it, these videos are amazing! You're the first person on youtube I've seen who's used science to make fun projects and thats amazing.
You could also wet sand the acrylic with a fine grid if you want that perfectly square "scientific" look, instead of dipping it in more acrylic. Just get a nice flat surface to sand on. You should do an failure test with the acrylic encased tube.
SeanHodgins That's what I was going to suggest, start off with some 80 grit and just keep going finer and finer. 10,000 grit should have it looking like glass. Speaking of glass, a flat sheet of fairly thick glass would make a good base for the sanding. Lay a sheet of sandpaper on the glass, get it nice and wet, and just rub the acrylic around on it. Rinse and repeat.
I love this! I'm in Chemical Engineering and phase changes are a huge deal, but we don't get to see a lot of high pressure phase changes in a hands on environment. I like that you've figured out how to actually make this stuff work on the small scale.
Hey Cody, I am hoping for a follow-up video! I'd love to see the process of the clean up. Also, Do you have any tips for a student applying to the U. I applied for next term, and I am curious as to what the environment is like? Thanks, Harry
Cody, you should send those acrylic tubes to Peter Brown (see RUclips) to have them turned down into polished cylinders. Would be a cool collaboration across channel genres.
ohmynoun Peter Brown was the first person I thought of when I say the acrylic encased tubes. They could create some pretty cool chemistry style lab/office/home decorations.
I've been watching a lot of hands-on chemistry videos lately. I have to say that Cody's are the best. He just feels more relateable than the really sterile lab-setting videos. I've been so inspired to start learning more and trying my own (safe) home lab experiments.
Still doing home chemistry? Did you get an amateur lab setup? I started when I found codys channel years ago. Slowly started buying glassware, hotplates, stirrers, chemicals, etc. Ive got quite the collection going myself
@@K0ester Wish I could say I followed through with this. I remember leaving this comment years ago. I never had the money to start anywhere meaningful. I ended up directly my creative urges into programming since that is mostly an exercise of the mind (where I don't need to pay for materials besides a shitty laptop one time). I never circled back around to it. Glad that folks are still finding inspiration from Cody though!
@@Shnugs hey, I get it. I would have never had the lab I have now if I didnt suddenly come Into about 14,000 USD at the right time. Im pretty jealous, I tried to get into programming and coding a while ago now. Never took it serious enough. Now I know nothing. I have put together quite a bit of general computer knowledge that helps me in my life, but never got the programming or coding down. I wish I did. How that going then? Make a job out of it or just a hobby?
we need Science teachers like him. I mean ones who are passionate about the knowledge they have and want to pursue more. I love this channel. Always in awe of what he does.
Cody'sLab where do you get a huge cylinder of nitrous oxide from? Whip its are fun! I laughed when you did it cause i was asking my self if you take hits of it
Wow, this time you really explained it all thoroughly! the chemistry, how to do it practically, even the failures and how to overcome them. I wish you did that in every video!
Hey Cody, just a heads up, it's usually better to not wear gloves when working with glass. If molten or hot glass gets on your hand, you get a tiny burn and it bounces off. If molten or hot glass gets in your glove, it is much, much worse. When I torch, I wear a leather smock and sodium-flair goggles, but no other equipment.
Every video I watch of yours Cody your very optimistic. Every time you make a small mistake you don't really beat your self up much, at least not out loud
The thermal conductivity of borosilicate glass is very very low. Thermal conductivity coupled with the fact he was heating annealed glass, is what allowed him to do this. When the glass is annealed, all of the stresses are removed, so there were no internal stresses to release and the thermal conductivity prevented the heat from traveling down the glass and creating thermal stresses.
Could definitely see the effects hitting him after he exhaled. I imagine describing what he was feeling during the cut between 5:25 and 5:26 wasn't worth keeping in. Probably just him saying "Woah! That was weird. I feel strange..." or some such thing.
影 Productions you're wrong, you certainly do get high from nitrous. You seem to not understand what being "high" means. Applies to all psychoactive substances. And yes, nitrous does impair physical and cognitive effects. Go take a whippet and see for yourself or Google it.
***** You're assuming too much from two sentences. You say "I am using the meaning..." did it ever occur to you to ask Sw4y what meaning he was using? In short, you lost, and now you're just digging your own grave so deep you hope to pop out the other side of the Earth, reborn. Good luck with that. Spoiler: It doesn't work. You were wrong from the start. Reread your initial reaction, reconsider Sw4y's words the same way you tried to defend your own, in light of Chris Grant's comment, consider apologizing for being rude (your choice whether you do or not), but then, *move on.* You've made assumption after assumption and you're only making an ass of yourself in the process.
***** Yeah you're not going to feel high on it at the dentist. Cody did roughly half a balloon. Recreationally that will get you high. Nitrous is a dissociative and certainly does impair cognitive and physical effects. His use of high only implied that the nitrous changed Cody's state from sober which it did. Just because you don't describe a feeling as "high" doesn't make it that way.
I'd like to see you test one or more of those acrylic-covered ampules to destruction (safely). On the one hand, it would be a potentially neat video. On the other hand, if you're going to store them, it seems to make sense to understand what happens if they fail. For example, if the acrylic doesn't shatter outright, does that mean it might develop one hole or crack and then rocket about in one piece? And, if so, us there enough store energy for it to cause significant damage?
this is actually an awesome way to store gasses... would be interesting to collect a sample of every element stable enough to deal with in a periodic table shaped acrylic block
this is dealing with questions I have had for a long time but was unable to find a source of data on...so at last my curiosity is at least partly satisfied....very interesting stuff..love it
Hey Cody, awesome video as usual. Encasing the tubes in acrylic. Genius! Safe and functional. I wanted to request you do some gases that change color when their state changes. Example. Chlorine gas(dangerous) is green, but liquid chlorine is clear(i think). Also gaseous oxygen is clear, but liquid oxygen is pale blue. There may be others with even better color changes. It would be interesting to watch the state change along with the color. Also interesting to use color as indicator of state. If you had a bunch of these of tubes with known temperatures of state change, you could arrange them to make a fairly neat visual thermometer.
This would be incredibly hard to get into the right state, but if you're looking for something with a fantastic color change as it changes between liquid and gaseous states. diatomic sulfur should be your friend. Problem is, diatomic sulfur would be a special case; as you probably know, at STP it's more favorable for sulfur to take on it's solid S8 allotrope, so to get it to a gas, you would actually need to DEpressurize it inside that tube, which may result in stable gaseous S8 instead of S2, and I don't believe that displays the characteristic violet color. Even still, it would be cool to have one of these tubes contain a solid and a gas at equilibrium instead of a liquid and a gas at equilibrium. (though there are probably better materials to do this with than sulfur, actually just plain old water might be good for that... never mind, you'd have to keep the temperature below it's triple point temperature, so i guess i'll look for another substance)
im not sure how you audience age range works because i dont know if its youngish or older bt im 14 and find you videos very entertaining and awesome and i dont know if thats weird because im 14 but ooh well
IM Jays watching Cody's videos is a good thing! try to learn as much about the science and I can promise you that later in life you will be very glad you did.
Excellent! I have a tiny capillary with xenon which does its thing at around 15C but yours are much more impressive. You've done the hard yards and reaped the rewards!
Incredible how that borosilicate glass tube could tolerate such a temperature differential. One end in liquid nitrogen, while the other end is being heated with a torch only a few inches from the very cold lower portion. I'd be afraid to handle that tube. Even though you waited before removing it from the water, there's always a chance it can still explode. Risky.
This. I came to the comment section to see if anyone else had mentioned Peter. Although Cody already has decent casts, he really could use the advice of Peter in terms of finishing the surface of the Acrylic.
King Kasper the best way to shine acrylic isn't to dip cast as he did - it's to wet sand then torch it with a cool flame. It causes the outermost section of material to level out. It's how aquarium makers get acrylic material crystal clarity for that 98 percent light transmission.
gromann Funny enough I am aware of that fact for the same aquarium based reason hahaha The point of the pose was in hopes that Cody saw it and hit up Peter from Shoptime. 1: He knows his stuff! and 2:I follow and enjoy both channels and i love colabs between science channels! [Shwood on The King of Random made my fucking day every time!!]
If the tubes can handle the hot water which greatly increases the pressure inside it then they can handle an additional 1 atm as well.. Or am I missing something?
It looks like this video was at the city house, instead of out at his parent's place where the vacuum chamber lives. ...hmm, that sounds a little stalkery.
Cody im curious. if you super cool a glass tube like that but without a balloon on it and just let the air in and seal it off, will it turn to liquid??
Comes out unharmed after drinking cyanide, dipping his hand in mercury, biting sodium, sealing gases under pressure in homemade glass ampules and more... But almost dies trying to hang up an axle stand..
There are two types of people: - people who think of "laughing gas" when they hear N2O - people who think of Nitrous Oxidide used in race cars when they hear N2O
I'm glad I watched the video you did with grant. It introduced me to your channel. Very nice videos, goes to show that chemistry is a lot more interesting that what you have to learn in high school.
***** Thanks for the imput, I thought it might be difficult, but I'll still try and find a way. It would be really cool to have some gold in a gaseous state.
Hey Cody - When cutting/sealing the tubes, I wonder if (delicately)chucking the glass tube in a cordless screwdriver (or any motor driven apparatus and using that to rotate it at the desired speed would help
Doesn't really make you laugh from my experience of NO2 for root canals since (in the us as far as i know) they only give you enough to "relax" you for the numbing needles. I'm sure when I get my wisdom teeth pulled it'll be a different story
dude, how much would you charge to make one of those for someone else? say i wanted to pay you for an acrylic sealed tube of Liquid Nitrogen. what would that cost?
Nitrogen would not be possible since it is a "permanent gas" but one of the liquifiable gasses would be doable, I'm not sure what I would charge or even if I would be willing to before I get some sort of automated process down.
hmm.. well if you ever decide to do special requests, i would love to have one. or at least learn how to make my own if there is no safe way to have it transported. this is one of my favorite experiments you have done on this channel.
this is by far one of the coolest setups i have ever seen, watching gases phase in and out of critical is by far my favorite chemistry experiment. i may one day have to copy this. another gas you might try is some of the canned air gases, i did a fun little experiment with those once using a 1 liter soda bottle... the warm water caused the cap to soften and become disengaged from the threads... it made for a really impressive rocket and a lot of atomized water. but there are a handful of different gases used, plenty of room for experiments and relatively easy to use.
depending on your footage video editing is one of the most taxing tasks a desktop can encounter, at 4k ssd's seem slow and the 32gb of ram you have will only buffer a few minutes of raw footage. at high framerates and if you use effects or transformations it becomes several times more taxing.
Damn, super cool stuff man. I was nervous the whole time that the tube would explode on you, ha
I found you, NileRed!
well, me know it didnt cuz the video got uploaded
also, i like your channel man
Id be more nervous about the Co2

Finally found you
Codysblab is a modern educational channel. One truly without bias and genuine intent to entertain and inform.
This guy is absolutely brilliant and so completely humble. Can't even begin to imagine what he'll accomplish in his lifetime.
I see that your lab is outside, 10/10 for ventilation, nice
your channel is growing so fast! And you deserve it, these videos are amazing! You're the first person on youtube I've seen who's used science to make fun projects and thats amazing.

You could also wet sand the acrylic with a fine grid if you want that perfectly square "scientific" look, instead of dipping it in more acrylic. Just get a nice flat surface to sand on. You should do an failure test with the acrylic encased tube.
He can also flamepolish the ground surface for perfect finish.
Oh yes, that is another way.

submerging in a bath of acetone is how acrylic polishing is done commercially (screwdriver handles, etc).
I’d think a quick dip or flame polishing would be a lot easier and less time consuming than progressively sanding finer and finer
I love this! I'm in Chemical Engineering and phase changes are a huge deal, but we don't get to see a lot of high pressure phase changes in a hands on environment. I like that you've figured out how to actually make this stuff work on the small scale.

Keystone science, Nilered and Cody all being amazed at gasses in glass. This is truly the sight of the century.
Hey Cody, just a heads up, it's usually better to not wear gloves when working with glass. If molten or hot glass gets on your hand, you get a tiny burn and it bounces off. If molten or hot glass gets in your glove, it is much, much worse.
When I torch, I wear a leather smock and sodium-flair goggles, but no other equipment.
If someone ever tries to rob you, just throw your collection of gasses at them.
Okay this was before you out them in acrylic
Omg your so close to a million! You can do it!
This collection is something I would enjoy seeing updates on from time to time.
Every video I watch of yours Cody your very optimistic. Every time you make a small mistake you don't really beat your self up much, at least not out loud
I can't believe the glass tube didn't shatter when half of it was dipped in ice and the other half being heated by a blow torch.
So the acrylic casing is for display purposes? No intent of using the gases in the future? Purely for viewing/possessing pleasure?
pretty much
If the glass does explode inside the acrylic, will the acrylic casing not act as a bomb of sorts? Or is it strong enough to withstand the pressure?
Bormann28 its probably noy going to explode considering the tube held up very well. And also adding like an inch of acrylic
The thermal conductivity of borosilicate glass is very very low. Thermal conductivity coupled with the fact he was heating annealed glass, is what allowed him to do this. When the glass is annealed, all of the stresses are removed, so there were no internal stresses to release and the thermal conductivity prevented the heat from traveling down the glass and creating thermal stresses.

Yes, you could!
Nope.

Nitrogen dioxide, when cooled, changes color. Maybe it might do the same thing with pressure? (I wouldn't want THAT to explode...)
And also what about bromine? Just curious.
Liquid chlorine is amber-yellow, i can say this definitively because i've made it myself. I have photos if you'd like to see them.
Holly fuck Cody, I was here when you had less than 10k subs... now you are almost 900k !
Congrats man!
im not sure how you audience age range works because i dont know if its youngish or older bt im 14 and find you videos very entertaining and awesome and i dont know if thats weird because im 14 but ooh well
Gold Solitude nice
Same here!
I'm only 11
IM Jays watching Cody's videos is a good thing! try to learn as much about the science and I can promise you that later in life you will be very glad you did.
Yeah and you can impress your friends with how much you know about the world and science and stuff! Knowledge is power, after all
Cody, your love of learning and experimentation is absolutely wonderful to see.
Thank you.
Excellent! I have a tiny capillary with xenon which does its thing at around 15C but yours are much more impressive. You've done the hard yards and reaped the rewards!
Incredible how that borosilicate glass tube could tolerate such a temperature differential. One end in liquid nitrogen, while the other end is being heated with a torch only a few inches from the very cold lower portion. I'd be afraid to handle that tube. Even though you waited before removing it from the water, there's always a chance it can still explode. Risky.
I want a pipe or crystal, can you help me with my private post and communicate
@@فضفضة-ص6ع wtf are you talking about
We need a colab with Shop TIme!!! I'm sure peter can help you make perfectly cast samples!
This.
I came to the comment section to see if anyone else had mentioned Peter. Although Cody already has decent casts, he really could use the advice of Peter in terms of finishing the surface of the Acrylic.
King Kasper the best way to shine acrylic isn't to dip cast as he did - it's to wet sand then torch it with a cool flame. It causes the outermost section of material to level out. It's how aquarium makers get acrylic material crystal clarity for that 98 percent light transmission.
gromann Funny enough I am aware of that fact for the same aquarium based reason hahaha The point of the pose was in hopes that Cody saw it and hit up Peter from Shoptime. 1: He knows his stuff! and 2:I follow and enjoy both channels and i love colabs between science channels! [Shwood on The King of Random made my fucking day every time!!]
I saw N2O on the thumbnail and just thought "he's gonna breath that in 'for science'"
Steven D. nice proper use of punctuation
you are my new fav channel. your excitement for stuff is amazing! never stop being curious!
One of the coolest, if not THE coolest gas video you have done to date. Really awesome stuff. I really enjoyed!
10,080 likes, 39 dislikes. Best ratio ive seen before.
its still pretty good 1 year later. 17400 and 98. one of the best channels on the tube
Yeah because it's Cody. You think people with a bit of brain could dislike Cody's videos?
Not possible. Cody rocks .
Jesse Mendoza exactly!
Cody has the type of personality you just cant dislike. He's such a likable person, and his videos are great.
I love your content but I would love to see more episodes of the mine series
Grandpa Ketsis me/2

I miss-read that as "gassing seals in tube"
Zaster lp that must be the only source of down votes on this video lol
I read Glasses sealed in tube......I should put my glasses back on
I like you the most out of everyone on youtube, because you stay yourself even with almost 1 million subscribers
Dear Mr. Cody sir, this was most enjoyable. I truly learn much from you. Thank you. pierre from New Mexico
They remind me of Fortress of Solitude crystals.
new mic sounds good!
Why not put the acrilic in a vacuum chamber to degas and increase the clarity?
Bike Jake I second this!
Probably because of the pressure differential it would create with the hundreds of, if not thousand+ PSI contained in the tube ;)
If the tubes can handle the hot water which greatly increases the pressure inside it then they can handle an additional 1 atm as well.. Or am I missing something?
It looks like this video was at the city house, instead of out at his parent's place where the vacuum chamber lives.
...hmm, that sounds a little stalkery.
Y'all are right. Just a brainfart over here.
This might be my favorite video of all, Cody. Really REALLY cool.
This is one of the coolest videos you've done in a while Cody. Keep it up!
Cody im curious. if you super cool a glass tube like that but without a balloon on it and just let the air in and seal it off, will it turn to liquid??
Yes, it will eventually fill with liquid oxygen, if the frost doesn't seal it first.
so just having an open dewar will result in liquid oxygen settling to the bottom and contaminating it?
In theory yes, but its probably such a small contaminate that it wouldn't matter much.
wax0re to make liquid oxygen you need to cool alot more
not oxygen, but probably nitrogen contaminated with water and particulates (air is mostly nitrogen)
What happened to the mine videos? I really enjoyed those.
Winter? So he doesn't want to do them? Or maybe some other complications...like a cat...
Cat? What cat? What cat?
Utah is cold right now!
mudkiptyler you know the cat that was in his mining video it had broken paw you could see it in. his foot
Didn't you see the video where he found that the gold mine was not profitable?
"yes, laughing gas"
me: breath it all in
I love how much hard work you put into your videos Cody, keep it up man
Great channel. Always cool to see a passionate backyard scienctist...with a very large yard.
Comes out unharmed after drinking cyanide, dipping his hand in mercury, biting sodium, sealing gases under pressure in homemade glass ampules and more...
But almost dies trying to hang up an axle stand..
Pierre Curie was hit by a bus. That is not the story we were led to believe in school.
His greatest weakness is butter
And gets nearly annihilated by a stick of butter
There are two types of people:
- people who think of "laughing gas" when they hear N2O
- people who think of Nitrous Oxidide used in race cars when they hear N2O
JC_mcsR53 *3 People
1- think of laughing gas
2- think of cars
3- think of liquid fuel for missiles and rockets
Macdeas yes. My bad. Lol
There are those that hear laughing gas and think of rocket fuel. ;)
***** yes, like Macdeas said. Haha.
Sorry, I'm more of a car guy. Lol
totally could tell u got nitrous high on that intake
Thank you so much, for adding a text where it says the temperature in C* :D
*Breathes in an anesthetic while standing up to demonstrate the density* Cody you're the man lol
I'm glad I watched the video you did with grant. It introduced me to your channel. Very nice videos, goes to show that chemistry is a lot more interesting that what you have to learn in high school.
Did I miss the step where he purged the atmosphere from the ampoule?
I figured you didn't want to hear the glass on glass screeching again.
Nope, its just a combination of atmosphere and gases, in which the atmosphere is only a small portion of.
Cody'sLab I did
Is it possible to store gaseous gold in a glass tube at standard temperature and pressure. I've always wanted to see and hold gaseous gold.
Holding it might be difficult... I have seen it though, it is a reddish purple color.
***** Thanks for the imput, I thought it might be difficult, but I'll still try and find a way. It would be really cool to have some gold in a gaseous state.
***** I was just thinking to get it to a really high pressure in a containor of sorts until it is gas and then keep it at that pressure.
Adding pressure won't make it a gas - in fact, just the opposite. It will make it stay solid at high temperatures where it would normally melt.
hobbified derp I meant low forgive me for derping out.
Hey Cody - When cutting/sealing the tubes, I wonder if (delicately)chucking the glass tube in a cordless screwdriver (or any motor driven apparatus and using that to rotate it at the desired speed would help
that is actually a pretty good idea! I'll have to try it sometime
YO CODY THE MIC IS DOPE THIS SOUND QUALITY IS DIVINE
Yep, the sound quality has gone up a lot! Very nice. Thank you whoever funded it =)
RIP Grant
I like when you say Ha, Ha! I am sure is Ha from Happiness!
Cienciabit: Ciencia y Tecnología. Greek and latin root perhaps?
how did you not laugh or smile when breathing in the nitrous oxide?
Nitrous Oxide or laughing gas doesn't actually make you laugh.
Doesn't really make you laugh from my experience of NO2 for root canals since (in the us as far as i know) they only give you enough to "relax" you for the numbing needles. I'm sure when I get my wisdom teeth pulled it'll be a different story
Minamur wierd, it always used to make me either smile or rarely laugh
LEAVE ME ALONE! got that? That's probably because of the placebo effect.
It would take a lot more than that to effect me.
This is by far the best science experiment I’ve seen on RUclips. I’ve probably seen thousands 😂😂
This is so cool! I don't know much about science but it's so awesome watching someone who does! Great video as always Cody!
You should do a video where you ionize different gases to see what color it gives off.
You should send those to peter brown of shop time to lathe those down and polish them.
agreed
dude, how much would you charge to make one of those for someone else? say i wanted to pay you for an acrylic sealed tube of Liquid Nitrogen. what would that cost?
Nitrogen would not be possible since it is a "permanent gas" but one of the liquifiable gasses would be doable, I'm not sure what I would charge or even if I would be willing to before I get some sort of automated process down.
Dude, it's art! You don't have to have a large-scale production method to be able to sell these.
Hi
hmm.. well if you ever decide to do special requests, i would love to have one. or at least learn how to make my own if there is no safe way to have it transported. this is one of my favorite experiments you have done on this channel.
I'd love to get my hands on one, maybe CO2 or N2O :)
The mic quality is great. Thanks for upgrading.
this is by far one of the coolest setups i have ever seen, watching gases phase in and out of critical is by far my favorite chemistry experiment. i may one day have to copy this.
another gas you might try is some of the canned air gases, i did a fun little experiment with those once using a 1 liter soda bottle... the warm water caused the cap to soften and become disengaged from the threads... it made for a really impressive rocket and a lot of atomized water. but there are a handful of different gases used, plenty of room for experiments and relatively easy to use.
Don't forget your guna have a really slippery step come tomorrow morning.
its raining right now so I say yes, very slippery.
ifell3 he should put farts in a glass
How about pure methane?
Nicholas Wallace he should separate the methane from the farts and then bottle them... 2 years later...
With the scrap glass you have you should make prince ruperts drop and do you have a source of cheap glass tubes
If you sell those I am buying them.
toysareforboys I don't think the postal service will appreciate a pressurized glass grenade 😂
toysareforboys I had the same idea but it's very hard to shipp those things i think (and i live in Portugal...)
I posted that comment the moment the video started. I thought it was under vacuum. I've already been in trouble for shipping pressurized containers :(
toysareforboys I want one too
+ Rodrigo Pereira same, but Norway. we will just have to make it our self
that microphone is great, massively increases the quality of your videos
This guy is my favorite youtuber ....thanks for the videos man.
Where can I buy one of these? I want to give one to my chemistry professor.
Man the new mic is great whats the next planned purchase for the patreon money?
Probably a computer that can handle adobe premier.
that shouldnt be too expensive at all if thats the only metric in mind
depending on your footage video editing is one of the most taxing tasks a desktop can encounter, at 4k ssd's seem slow and the 32gb of ram you have will only buffer a few minutes of raw footage.
at high framerates and if you use effects or transformations it becomes several times more taxing.
RIP Grant thompson
I'm glad I can look up to Cody as a role model.
I like your videos, they're extreme... I remember one video you did with bees and your face was all swollen.. good times... keep up the good work
