Cody Reeder and the Vacuum Chamber of Secrets
you can see him cast his spells at the very end
Everyone in Utah: Hey its snowing
Cody: FIRE UP THE VACUUM CHAMBER. SCIENCE TIME!
Codyslab is a hacker... I saw him using cheat codes to make that snow...
Which is obviously against the weather's Terms of Service...
You must expose him Verlis!!!
Verlisify now I know who to blame for this horrible mess!
Oh look I found a furry.
Verlisify in Utah it's either 100 degrees or -100 degrees.
Poodlecomb I can confirm this.
You're actually using the freeze drying chamber for it's intended purpose
MrTurboturbine Its*
Perhaps he's feeling under the weather. We should let it slide... this time.
MrTurboturbine
“For it is intended purpose”
Seems legit.

It's an optical illusion. If you look at a phase diagram you'll see liquid water can't exist below 0.006 atm, and his chamber was at about 0.0007 atm. In fact water evaporation can only lower the temperature to around 0.01°C, regardless of the pressure.
Omegapede Prime
It’s too low pressure, and too cold to be liquid. At this pressure it acts like dry ice.
Next up on this playlist: High-speed footage of grass growing.
I'd still watch it... :/
I would watch that unironically if cody posted it.
Sounds so exciting! In 360 though please
Uriah Siner sesame street already did thay back in the 1970s.
I'd watch it too through a time lapse
"Let me stick my finger down in there, HaHahahaha, that feels very cold"
-Cody 2018
Welcome to the internet
Internet, Welcome to Cody..
Dammit! Beat me to it!
id not be surprized if he stuck a bare hand in liquid nitrogen
haley sticking your hand in liquid nitrogen isn't dangerous, you can even pour it onto your head.....liquid ice challenge...
Most people when they see snow: we could make a snowman
Cody: Let's put this snow in a vacuum chamber
put a snowman in a vacuum chamber
neutrocity That'll be the next Cody's lab video
Make a vacuum chamber out of snow.
And get dem vews
"Do you wanna build a vacuum?"
:)
I guess it's melting so slowly, because there's no atmosphere to transfer energy into the snow. So the only energy available to melt the snow is radiant energy, which is substantially slower than conductive heat transfer :)
and the heat conducted by the cardboard
also, the little amount of snow that does melt, instantly evaporates, cooling the snowaround it down.
I think a bigger effect is with no liquid water, the conduction from cardboard to snow is weak, but with liquid water the conduction is spread over a much larger area.
If melting point goes down it needs less energy to melt/boil(in this case, sublimate) so intuition would sat that it should melt faster. Danielle is also technically incorrect as most of the energy is probably heat transferred from cardboard since it would absorb more light than snow which is mostly reflective although you had the right idea
Pressure does not change the melting point
I knew you were a fire mage. That bonus video proves it.
That's just the element Snowdium.
He's a hairy wizard.
It's his homemade lightsaber
More like a vacuum mage
LordDragox412 yeah, his name is Hairy Twatter...
TH-camrs do all kinds of crazy stuff for views and us nerds are just sitting here watching snow melt for 10 min.
Stay warm! Hope you're faring well amidst the youtube chaos!
Xzendon Ultimus ok
Nice to see that youtube hasn't demonetized you yet!
not entirely at least
Hey, something is still better than nothing
Leave it to Cody to make watching snow melt interesting. What's next, Paint drying?
Poontang Smasher5000 paint drying in a vacuum at elevated temperatures in slow motion.
Well, depending on what solvents and polymers are used in the paint, watching it dry can be quite interesting. Certainly the manufacturers need to know this sort of thing! Hammerite is my favorite.
Poontang Smasher5000 don’t give him ideas
I would watch that
Sixty Symbols have a video all about paint drying !
FBI file #42069 (Cody'sLab): mad scientist, wizard, nuclear bomb maker; individual possibly highly irradiated and mercury-laden, approach with caution.
Also magnetized, you forgot magnetized
Thanks for the upload, Cody! I love the consistency of your uploads and quality content!
We need a Cody'sLabinSpace.
Pray to Lord ELON!
So far all we have is a Cody's Blab! :-P Babble on!
Always a massive fan of the content you bring to the interwebz. Thank you Cody.
I can see it now: the DANGERS of twice vacuumed water
That dihydrogen monoxide is nasty stuff.
Maxx B I think you mean dihydrogenoxide since monoxide = CO. when there is just 1 of something you don't have to put mono in front of it.
AnimationCraft H2O. How many O's do you count? H's? How many C's do you count? Now ponder that relative CO and CO2. Key details in differentiating carbon monoxide from the dioxide form and dihydrogen monoxide. However, yes, some texts do omit the "mono" from some chemical names for ultimately arbitrary reasons, typically because it's assumed "oxide" means "monoxide" meaning 1 oxygen atom attached
No. Monoxide: mono-oxide, literally means one oxygen.
The full name for CO is Carbon Monoxide. There are a lot of monoxides that are safe, namely dihydrogen monoxide.
oxide by itself is used when a compound has one unambiguous or commonly used oxide form (form with oxygen in it), but an oxide can have more than one oxygen in it.
most of the times when mono- is omitted from something containing only 1 oxygen is when the molecule is ionic in which case the prefixes aren't needed.

Cody: "Oh, I just shorted something out."
Me, and EET major: "No, the resistance maxed out, so you made an open, not a short."
A truly sublime video
I don't know how do you do it... Making watching snow interesting.
Just think about it conceptually:
>Pointing camera at snow.
_"I tell you what, I'm going to switch out the lenses and get a nice close-up shot"_
_"I think I actually saw a flake move over there"_
omg it's Cody Potter
This is a pretty good way of showing why comets are solid ice and don't turn into liquid when they pass by a star. They just sublimate and that's why we see a comet tail. Also, interestingly comet tails don't indicate the direction the comet is traveling, they do however indicate which direction the stellar winds are traveling.
This video was sublime.
Henry's Law. There's vapour pressure on the ice, you could've got more going without a lamp on it if you had put a fan in the vaccum chamber.
Thanks for being awesome! Utah is beautiful ain't it!!!
really blows my mind to see the snow melt, but not to see any water coming from it. i kept doing double takes watching it...
nice work!
*I HAVE TO WATCH IT BEFORE IT MELTS!*
The resistance of something is dependent on 4 factors, length, a shorter wire has less resistance than a longer one. Width, a thicker wire has less resistance than a thinner one. The material, it's strength of hold on electrons, (less hold means electrons flow through without being slowed as much). And temperature, which Cody uses in this video. (The colder it is the less resistance it has). So if you know the rate at which resistance drops for every dropped degree temperature, you can measure the temperature of something by getting your copper wire to the same temperature as it, and measure how much the resistance drops.
So states Ohm's lawa in a lot more words.
**Upset german**: "At least you have snow... "
well at least you CAN have snow.good luck find that shit here in brazil
GraveUypo Lol, fellow South American, greetings from Ecuador, we got tons o snow... Up in the mountains and volcanoes ;)
Jaja. We CAN have snow, but for like 3 years there´s just rain, rain and rain.
*Grumpy Brit* Rain.. RAIN! Don't talk to me about rain!
lmao I think it snowed in Florida a couple days ago
I love the fact that Cody posts videos about stuff I am learning in class. I wondered whether or not water would instantly evaporate in a vacuum because of the reduced atmospheric pressure and it kinda does.
You get more control if you practice using manual focus on your camera
Degrees Cody, I like it!
so. what was that thing at the end?
Petar Tsankov NaK that comes into contact with water (snow)
Thanks, I mean, I knew it wasn't fairies running around with tiny fairy sparklers in their hands. I knew that.
Cody is a wizard and he was casting spells, obviously :)
im thinking its a sodium powder wand.
I'm pretty sure he was battling invisible Ice Faeries.
Cody’s videos are amazing. Vacuum is interesting, snow is cool; But Cody reveals the mysterious world right in front of us.
Cody what the heck was that at the end and where do I get one
RB
You have to be a wizard to get a wand xD
Cody's a wizard.
The coolest snow DM whip ever
Utah really looks beautiful, boiling summer and snowy winter
It will be interesting to see thermal imaging.
If you think about it, snow is just delayed rain. It becomes rain when exposed to warm air or a warm surface and piles up until it warms up, then it becomes like a huge rainstorm that only happens on the surface.
Cody you should do chemical reactions in the chamber that you can only do without oxygen!
100% nitrogen box same, but without the vacuum pump damage.
Nothings happening, nothings happening, nothings happening... OMG!!! Greatest show ever!! Took forever for that LSD to kick in.
Cody what was that at the end man ?
magic, i'm not very good at it yet.
teach me master !!!. or better make a video of how you did that
It looks like he has a pipe with a tiny hole in it and when he swings it a water-reactive jet streams out. So when it hit the snow it ignites. I wouldn't doubt it was sodium or potassium as we have seen Cody do that before
sodium because of the color?
Its actually an idea I was working on for igniting a liquid fueled rocket engine.
I must be desperate for something. I’m watching snow melt in a vacuum chamber
why didn't you laser it :(
The snow is so white that it would reflect almost all of the light from the laser.
Goes on TH-cam while I should be studying... *see's notification from Cody'sLab starts watching it*
Mother: Aren't you supposed to be studying?
Me: Yes.
Mother: Then what are you watching?
Me: Snow melting in a vacuum chamber.
Swish and flick.
Forssa1 Swish and dick?
Wow!!! over 3000 people watching snow melt! Thanks for the videos.
Would you be able to melt ice applying pressure with a thread, in vacuum?
Well atmospheric pressure play very crucial role in state of matter. As it have been seen that if you put liquid nitrogen inside the vacuum chamber you could possibly see solid structure of nitrogen. In short pressure do play an auxiliary variable in solid state physics
what was that at the end?
Cody sees it snowing outside and thinks "This is the perfect time to make water skip a stage of it's cycle." I love how creative you are!
Did never thougt about this before!
Great Experiment!
The firm IDE uses a vacuum to make snow at any atmospheric temp. Used in deep mine cooling, and making snow when the air temp is above freezing I believe.
You better not start saying rice is magic, cause Grant's speciality is "random shit in a vacuum chamber"
I did vac chamber stuff first!
grants specialty is felony charges lmao.
A lot of us would have felony charges if the ATF really took a look at who had explosives and who didn't. Pro tip: If you are going to blow stuff up either do it in the middle of nowhere with no witnesses or really really know your neighbors (or include them in the festivities).
You could also get a permit, but who does that anyway.
carolyn mmitchell you made me chuckle like a gremlin
So, I was thinking of a related experiment I'd like to see with the vacuum chambers. It'd be interesting to watch the difference in the speed heat radiates at under vacuum. I think a good way to demonstrate this would be with red hot metal both inside and outside the chamber. Of course, you'd run into an issue drawing a vacuum fast enough for this. A possible solution is using the larger chamber as a vacuum reservoir and have a vacuum pulled in it ahead of time. Connect the two chambers with a valve, and once you've gotten the red hot metal on a plate or whatever in the glass chamber, pull the valve. I'm unsure of the volume of your chambers or how well the smaller one would hold up to that quick of a change in pressure, though, so that might not actually do much.
Awesome!!
watching snow melt on Cody's lab is still better than anything on cable
Vacuum chamber is back :)
"But each one of these things comes from an egg, right?" - Ripley
I am surprised the snow melted so fast, a vacuume is an extremely good way to insulate
Next do "Watching paint dry in a vacuum chamber"
I would watch that.
ttsgeb Not gonna lie, I would too
Stylish Buffalo I bet paint drying in a vacuum chamber beats watching paint dry in atmospheric pressure because paint should dry faster in a vacuum chamber
wouldnt it be bubbly?
**watches bonus fun video of Cody saying something and watching a line of light lit up** "You're a wizard, Cody."
if you put a magnet in an icecube and get it levitating in a vacuum chamber, will it melt?
Much more slowly than a normal icecube outside the chamber, but yeah, what the person above me said :)
Thank you, I was just explaining sublimation to my 7 year old. He had learned about the water cycle and wanted more info. Now I show him the video.
This is called thinking out of the box!
One of the reasons I subscribed!
Thinking out of the chamber
You have done it! You've made watching snow melt interesting.
Can you do the same thing with your sprengel vacuum pump?
the sprengel is way too slow for this
Johann He's using a desiccant. It's theoretically possible if he can thermoelectrically keep the snow cold until he gets down to full vacuum
Can I just say that your new intro is amazing. Well done Cody!!!
When i saw that Cody posted, I stopped what i was doing to watch.
kokon dodon what were you doing?
Bass 'n'Bluegill "Doing some research"
me to. :-)
same. i was watching Digimon anime
same here..haha
I miss Cody’s old intros, his current one doesn’t come near to showing how awesome he actually is
What was that at the end? Sodium?
Felixkeeg i think it was zinc powder, ammonium nitrate, and sodium chloride, but I’m not sure tho
It's Sodium Potassium alloy, aka NaK. It's a liquid metal that burns when it gets wet
don't think it was NaK, it'd burn under normal air due to moisture
Felixkeeg after a snowfall as long as it's cold out there is almost no water vapor in the air. Contrary to what many think you actually need some warm air to make snow, it cannot snow at all once you get more than 20 degrees or so below freezing, not enough moisture in the air.
Felixkeeg buddy moisture is too low in utah.
only you can make watching snow melt interesting
Apparently hot water freezes faster. A video on this would be interesting or maybe you've already done it.
Mckayver I tested this for a project in 7th grade. From what I remember, the initial temperature makes almost no difference on how quickly the water freezes.
I'd love to see Cody's take on this. Apparently called the Mpemba effect. It's a recurring phenomenon in certain conditions and circumstances but does not occur all the time. Scientists can't seem to agree on what causes this.
I had a look through the videos and it doesn't seem like he's tried this.
I tested this several years ago and my results indicate it most certainly does not. Hot water has more energy that has to be removed then cold water. well, hot water will drop quickly due to the temperature difference it never seems to catch up or beat the cool water. I started with hot water and cold water as supplied by the sink. maybe 120° & 60°. filled two cups with each and placed them both in the freezer. checked up on them every so often. the one started out cold started to freeze well ahead of the hot one. by the time the "hot" one started to freeze the "cold" one was fully frozen.
did the same with boiling water. on the stove top and timed it. hot boiled quicker than cold water
But he boiled water in a vacuum until it froze, to it's kind of similar.
for god sake, someone make a proper intro for this amazing creator! he deserves it at this point.
Lol we got over 1m of snow here in northern finland
xKuukkelix Damn We get at least a quarter of a meter.
xKuukkelix We even had some snow here in Ireland. Not enough to last over a full day, mind you.
It makes sense that sublimation would be fairly slow under these conditions. It still requires energy to go from ice form to gas form. In vac. the available energy is restricted quite severely.
Can you put coal or carbon in the vacuum chamber and see if it turns into diamond?
Thats actually not as absurd as it sounds and is on my list of videos to do.
I thought you need very high pressure, not very low pressure?
That would have the opposite effect. You could probably turn a diamond into carbon with a vacuum chamber
Cody'sLab remember the trick that ElectroBOOM suggested? Do it again but with a pressurized CO2 cartridge
Wait, Cody, you're actually serious? Whaaatt?
Utah has beautiful snow, Knowing this is what happens to Utah snow makes me want to do re-do this Experience
Wow, I tuned in to see "Snow Melt", much like when I watch water boil, takes some time, light the bong!
Daym im glad i found you cody. Theres something about your videos. Soo Educational
I've seen snow sublimate away in a few days if the sun outside is intense and strong enough. Usually happens with the remnant snow after shoveling a sidewalk. Still some degrees below freezing when it happens, so it's not melting in the usual way. When it happens at atmospheric pressure I'd guess it tends to be more of an intense light driven process than a temperature one.
i could just picture cody on a cliff with him holding a lighting bolt shouting, SCIENCE
Hey Cody! Long time veiwer that's lurked around but never commented. Love the new intro music! IMO maybe make it just a little longer, maybe 3-5 sec longer but I really like the idea!
Thanks a ton for your content, I really enjoy your channel, and it's very unique here on TH-cam.
You rock Cody (sometimes literally xD), and I hope you continue making videos and that all is well in life!
I watched this whole video now and I don’t know why but I really want to see him dry paint I’m not sure if I’m the only one but watching snow melt was low key fun to watch and paint would be the the best
watching snow melt inside a vacuum chamber is way better than watching paint dry.
that "incendio!" part at the end is cute
Hahaha, i love how pleased Cody is with his dry ice comment.
I would have thought the display on the meter would be affected by the vacuum. Isn't it a LCD?
The coolest snowdium whip ever
This takes me back to the days of watching paint dry!
In science laboratories, this method would be called freeze drying where you convert ice into gas directly for protein purification purposes.
Thanks Cody. That was awesome to watch. I would love to see dry ice in a pressure chamber to see how it would look going from solid to liquid CO2 instead of solid to gas at atmospheric pressure. I don’t think you have a pressure chamber though.
One of the few channels I can preemptively thumbs up!
JERRY SPRINGER FOR PRESIDENT 2020
JERRY stands for Codys lab to test all chem trail powder.
I just noticed that Cody has a very convincing mad scientist laughter.
Water also does it in atmospheric pressure. If you hang laundry outside in below freezing temperatures it will dry.
"this is exactly how you'd expect snow to melt" *evil laugh*
No more shoveling snow just vacuum it up and it turns into gas. Amazing!
The end confirms that Cody is indeed a wizard.
What a surprise snow melts.
The ending was much more fascinating
Watching snow melt, what captivating entertainment
I know right!
