Thanks so much for watching! If you would like to see my reaction to someone who actually attempted to make a homemade nuclear reactor, please check out: kzfaq.info/get/bejne/iLOjmM2IxNu7aac.htmlsi=hlb2hKSbCaljnr-n

Cesium 137 was the isotope behind the incident that happened in Brazil. There was an old x-ray machine left behind in an abandoned medical facility. Two men broke in to find scrap metal to sell and decide to take the machine. They opened and found the cesium powder. Everybody got curious about it because it glows blue in the dark. A child played with it rubbing all over her body. Four people died and 249 got contaminated.

Nigel likes to taste (or smell) *everything* he makes. Often making things just for the sole purpose of tasting it. He's an adult with the abilities of a scientist but the intentions of a toddler. So the joke about tasting the yellow cake gave me a hearty chuckle.

Mr Green may do mostly parodies, but he actually knows what he's doing and is a pretty smart guy.

5:02 I love how folse’s face goes from “HAH this is hilarious” to “Wait a minute that’s legit” in a matter of seconds

This person started out with a channel called NileGreen making just these parody NileRed videos, but after a few videos, NileRed got in contact with him to talk about it. Not in a bad way. He enjoyed the videos, but there definitely was a chance of confusion, especially with the use of the voice trained ai. From what NileRed said on a podcast, MrGreen is actually also a chemist, both from Australia iirc, and he got in contact with him over someone just happening to know them both.

I believe the bigger issue with metallic cesium was that it is highly reactive in oxygen and water. It's an alkali metal, like potassium and sodium, but far more reactive.

The video he "got the idea to make a nuke" from is a real one, and he even actually said it looked like a mini nuke in that video. It's called "this chemical really doesn't want to exist." And the one where his dad walks in is from when he made bromine in his parents' garage. You might want to watch that one, because it's probably one of the least safe videos he ever made (bromine is pretty dangerous), and he talks a lot about the safety precautions you should take and how he managed it in such an uncontrolled setting. Also, since I'm already recommending videos, I don't know if nanoparticles or superconductors are used much in nuclear engineering, but if they are, you might want to watch Nile Red's videos on making ferrofluid and a high-temperature (as in, liquid nitrogen is cold enough) superconductor.

Cody's lab youtube did actually show how to refine uranium ore into uranium metal. He even was graced by a visit from the US Department of Energy because of it. You can still find the vid on youtube to this day.

The MrGreen channel used to be called NileGreen and only posted deepfake parodies of NileRed. I think a few people didnt immediately realise it was parody and Nigel, who loved the videos, wasnt super keen on his branding so he changed it to MrGreen. Theres an episode of the safety third podcast where he comes on and they talk all about the channel together!

he was originally NileGreen, but was nice enough to change his name when NileRed asked.

Mr. Folse your channel is absolute gold!

Actually youd be suprised to hear that nile actually does his best to voice his work as professionally as possible, he states that he doesnt like takes where there's emotional influxitions because i think he wants to be as objective as possible. While this seems weird, youd be actually thrown into a hole of flabbergasted "what? How?" Because the ai voice models trained on his voice express MORE emotion than his official videos. Which i think, is pretty damn funny

The reason why the barrels looked realistic and the radioactive labels looked legitimate is because they were. That footage is from a Sci-channel episode if How It's Made on Nuclear Power and Waste Disposal. You can see the watermark in the bottom right of the screen. Lol.

Nile Red made grape soda out of latex gloves. The dude is literally an alchemist.

0:07 I heard from someone that when you say "more than a decade of experience" you sound more professional than "over 10 years of experience"

btw, Mr. Green was originally named NileGreen, but changed it because some people actually thought it was Nigel.

NileGreen was an amazing DeepFake (audio and video) from an Australian on the channel NileGreen. They changed the name at Nigel's request, but he thought it was hilarious. They met and discussed it on the Safety Third podcast.

You've been one of my favourite KZfaqrs for the past little while and I've been on a watching spree for the past two weeks haha, your videos are great and it's nice that you have extra knowledge to add on to most of the topics you react to

This parody is so good, so glad you reacted to it :D

"Do not grind cesium 137 and put it in the water reserve". Why does that sound like I need to do it?

Mr. Green is actually insane... You should watch his video where he tries to make a literal bath bomb. A bath duck shaped chunk of sodium.

This is some great content, especially since your a smaller creator. I alos love the nerdy parts where you pause stuff to talk about it. Very cool stuff (:

The main thing I've learned from these videos is that nuclear science has more units of measurement than any other science or profession. I hear a new measurement term every video.

I love this dude. Don't stop making these!

I enjoy watching your videos. They're full of information about nuclear physics and engineering. Plus I find them highly entertaining 😂 You should have more subscribers on your account.

mr green used to be called NileGreen and made fake and dangerous tutorials voiced by an ai of NileRed. it was all parody but people started getting mad at NileRed thinking it was him making dangerous tutorials so mr green changed his name. he actually went on NileReds podcast and they talked about it, was pretty cool.

We use cesium-137 all the time in construction for our "nuke-gauges", and are used to test the compaction of soil by measuring the moisture content and density in situ and are calibrated against a plastic block every day before use

you should watch "i made the world's most dangerous bath toy" by mr green

"I don't claim to know everything nuclear, but" What does polonium taste like?

Best quick guide to enrichment ever ❤

What you said about Caesium is true for the radioactive isotope involved with nuclear stuff, however more conventional caesium is an alkali metal similar to potassium, only even more reactive and explodes on contact with air in a liquid state.

Mr Green's original videos only used AI to make a NileRed voice over, and they named their channel "NileGreen", which is why people refer to him as that.

The trash taste pod cast actually had Nile red as a guest , I would def suggest giving it a watch even on your own time. It’s funny and gives a background on Nile red , path with chem and there are specific clips of the podcast about radioactive substances if you just wanted to focus on that

I love how in Factorio, to can recycle 238 outputs back into your centrifuges to increase the 235 outputs.

Hi i like your vids, i just wanted to point out that at 2:34 you said Cesium is radioactive, cesium has a stable isotope cs-133 so its not considered radioactive, but i think you meant cs-137 which is a strong gamma Emitter and the most Well known isotope of cesium!

Why do I feel like I’m going to be on a watchlist for this

MrGreen use to make videos of Nile Green. Yes, they're Nile Red parodies, including the simulated matching voice. Both Nigel (Nile Red, and Nile Blue [2nd Chl]) and MrGreen showed up on the same video of the Safety Third channel, where Nile Red is a regular. The rest of the Safety Third crew (Will Osman, Alan Pan, & Kevin [Backyard Scientist]) like to pick on Nigel.

Cesium has different isotops with vastly different dangers

I always thought that only U236 was depleted Uranium as it is neither fissile nor fertile. U238 is still a perfectly good fuel for breeder reactors so it is not really completely depleted. Although now that I think about it, there are not many breeder reactors around so there wouldn't have been much depleted uranium to go around if that was the case.

I love the bit about the yellow cake. Sure looks good enough to eat!

Just thought I would chirp in here for a second but yes there is an entire hobby about buying radioactive rocks and minerals

been watching you channel for a while and have never seen these video.

The music at the end is just Mark Rober’s background music with the bass boosted.

Mr.Folse your channel is absolute Au!

When I built my nuclear reactor at home, I was having trouble enriching uranium, but found that it was easy to enrich hydrogen via electrolysis. So I bough 15 tons of unenriched uranium and used it with the several tons of heavy water I made. Now my Canadian friend thinks it looks familiar. No idea why. I totally didn't use plans from Canada.

as a person who commit war crimes in a daily basis, This is a really Informative nice Video. Now where is my Ground up sulfer and Uranium Powder I was going to accidentally sprinkle into the waterway..... hmmm

"you cant buy uranium.. what? how is that legal?" "its a good price too!" cracked me up good 🤣

This guy's videos called "If NileRed was bad at chemistry" are a great recommendation too lmao. Both parts could probably be watched in the same video :)

Why does he watch genshin impact

im from brazil, and i can confirm that cesium 137 is healthy and you should use as a decoration. also as a paint, its up to you, but i really like the cesium paint, its glowey.

Fun Fact: This whole "UF6-Tails-Reprocessing" exists as a researchable Recipe in Factorio (Base Game, Unmodified) and it's called "Kovarex Enrichment" where you have an input of 40x U238 and 5x U235 (DISCLAIMER: Recipe might not be 100% accurate to the Game because i don't remember it exactly) where the output will result in always 1x U235 and 1x U238 more than the input was (In = 40-U238 and 5-U235 -> Out = 41-U238 and 6-U235) which you can infinitely re-feed into the Input to gain more and more U235 for the creation of Nuclear Fuel Pellets (this also needs Heat-Pipes and Heat-Exchangers as well as Steam-Turbines to generate Power, just like a real Reactor would work too)

Wait, you finally react to this? How did I miss out 😂

If you doubt it was his video, you missed the difference between NileRed and NileBlue

Just FYI, that lift-off light is from the console of the Titan-II commander's panel.

Caesium shouldn't be mixed with water because of the radiation, but because it violently explodes upon contact. It also reacts with air, so it is often kept in these weird vials.

cesium melts on a nice summer day... like 83 degrees F. Does it splash and splatter, or does it stick together like mercury?

nile green actualy knows chemistry

2:57 the Brazilian city of Goiânia knows that very well. I went to the place where it all happened, it's an empty slot covered in concrete now, it's in downtown, it's so safe that there are houses right next door to it, very underpriced of course

How come you always choose the best videos? :D

Wait are you just telling the world that you could make a terrorist attack with cesium 137 in the water system 👀💀💀💀

Damn nice freakin content and channel 👍

I like the fact the end of your uranium distillation run is called the tails, just like making moonshine

First time I see him actually reacting to something in his field. First time I'm interested in his reacts.

Just a bit of sillyness.... the image at 10:16 in your video of the button that says "LIFT-OFF".... I think that's from a minuteman rocket silo, I saw it on a history of nuke weapons video. @mrgreenguy went through a lot of effort to get details right.

2:40 isn’t cesium that stuff that only comes in standardized solid tubes with “DROP AND RUN” on the side?

The way his facial expression changes the moment something he knows is mentioned and is correct

I always had the question of how much radioactive stuff I had to intake for that to be an issue? I know that it differs from material to material so i thought of this little example because that something that could happen to me almost like this. Lets take the cesium metal that nigel was showing in his vile. I look at the vile, I open it and play with the metal. By playing i mean having at in my hand, letting it role around, looking at it from different angels and lighting. After that I heavily lick my fingers, can that be a huge issue? Would it be an issue if i play with it and afterwards I role a ciggi and smoke it, would there be enough particles for me to intake for that to be an issue? I just wonder how big the dosis of radioactive material has to be for concerns. My guess would be that it is pretty low.

Congrats on 30k subs

it's cute how he's confused by deep-fried mark rober music

The "Lift-Off" / "Abort" lights are from the Status Panel of what appears to be a Titan II Launch Control Center. After the keys get turned, and the votes are tabulated, the Countdown and Launch Processes are automatic - the Status Lights show what the sequence is doing. And for UF6 - Not something for use in the home. Nasty, nasty stuff. something with 1 Flourine is Bad. Something with 3 Flourines (ClF3, for example) is Evil. Something with 6 Flourines is not only Psychotic, but scratching at the walls trying to get out.

I’m pretty sure Cesium is also highly flammable and will for sure explode

Almost bought 100g of cesium salt but then i decided that would be a bad idea

So: Dont make organochlorine compounds out of radioactive chlorine And then finely disperse it across an area Got it. Refinement via gas diffusion seems Like the column chromatography of the enrichment world

Ibthinktrhe Manhattan project had multiple bases with multiple warehouse sized buildings dedicated to enrichment.

Pov: me eating uranium worth of 45 billion calories *it was very tasty*

have you done codylabs video on making uranium metal

perfect title shot man!! hahaaaaaa

thanks for telling me about the Cesium 137 i'm totally not gonna poison the cities water supply!

Cesium explodes on contact with air and (significantly more violently in water though)

Fun fact with the proper tax stamps a US citizen can own a nuclear bomb however they are not allowed to detonate it. Literally no weapon is outlawed in the US if you have the proper amount of money and paperwork plus storage, but the storage part no one really cares about unless it is like "Oh no i misplaced my nuclear bomb" ......yeah not only would you be banned for life from owning any NFA item that point onward you would probably be in prison for life if you misplace something like that But yeah any explosive falls under a NFA item including Nuclear bombs meaning you need the proper paperwork, also depending on where you live there are state and or city laws that might prohibit it, just like owning fully automatic guns is outright banned in some cities despite the state and federal government allowing it given the proper paperwork. It's also funny that full auto guns are more restricted and deemed more dangerous despite semi auto actually being more deadly as you are not wasting your ammo with semi automatic guns and you have more control over the gun, and by semi auto i mean it fires as fast as you can pull the trigger which is honestly just about every non single shot non revolver these days and also non pump action guns. Yes i just made a parallel between nuclear stuff and machineguns as the public fears them both unjustly when we have even more dangerous stuff floating around the US, granted nuclear bombs may be a bit of a stretch to have but that aside nuclear in general is unjustly feared just like machineguns

Now this man now’s how to make ethical reaction content

Did you watch William Osman building an x-ray machine? Can't find it.

curiously enough, mrgreen is actually a very well trained physicist, engineer and chemist. So it isnt quite that surprising he has that attention to detail considering his expertise in these fields

I would like to ask you a question and I am really asking. at 10:25 a Trinity and beyond atomic central. I have one question. During this "so called blast" as you watch the blast I want to ask a simple question about this clip and yes you can find more videos of this event. So I have to ask you. 1. Why don't we see the typical radiation distortion in the film that we see in the tests. 2. I then have to ask and this one will get you to start thinking. The buildings are moving and effected by the blast right? We can see this right? So why isn't the camera effected. I rest my case.

I had to search for a long time but I found a video that claimed it was showing what the computer was displaying during Chernobyl accident. The video is called the last signal of the Chernobyl reactor. I was wondering if you could do a reaction and give us your insight as a engineer.

One day, NileRed will make a tutorial on making a planetary sized nuke”

8:45 obligatory "DONT EAT URANIUM" message here

First time i see a reactor reacting to a reaction video

Ferb I know what we're going to do today!

Read the NileRed romance novel, "50 Gray in the Shade."

Ok but does a washing machine spin fast enough to enrich uranium? Asking for a friend.

When you made the uranium green glowing glass

How many times can the tails be recycled?

I kind of thought MrGreen was Red Green, advanced beyond duct tape!

You should watch Explosions&fire "which salt tastes the best?"

mr green when he first started his channel he called it nile green, but he changed it after he got a lot of traction

Just wondering. How long does it take to become a nuclear engineer? To get certified etc.

i learned cesium actually _is_ a bomb, if there's any water or even just plenty oxygen around.

You should watch the video that John Oliver did on Nuclear waste. Love the videos btw :)
