Happy new year I know it's not nuclear but it's a good one I remember when it happened because it woke me up and I lived in Milton Keynes at the time which is about 30 miles away The Buncefield fire was a major fire at an oil storage facility on 11 December 2005 at the Hertfordshire Oil Storage Terminal, located near the M1 motorway, Hemel Hempstead, in Hertfordshire, England
I'd like to mention the SNAP-10-A or 'SNAPSHOT' satellite experienced shedding whilst still in orbit in 1979 losing more than 50 pieces of debris. (Hopefully none of that came down here!) It also was equipped if I'm not mistake with a Cesium Ion Thruster making it the first electrical propulsion systems ever used in space on top of the first nuclear power plant. Might be worth adding this to the video at a later date I found this data on wiki however so it may need some source checking.
Someone made a timeline of all the nuclear explosion tests on earth an ran the years up as explosions happened all over the world. Once China got involved it really became a fireworks show 60+ crazy how we react so fiercely to a little melt down when half the world has had large unregulated "tests"
@@mrillis9259 You are aware that the United States has done more nuclear tests than almost all of the rest of the world combined, in addition to being the only nation to use nuclear weapons on civilians (twice), right? The United States did 1030 tests, USSR did 715, France did 217, the UK did 88, and China did 47 (note that some of the UK's tests were done with America on American territory. If you count those as American tests, the UK did 45).
Tsar bombs size was so insane (my bomb is bigger than your bomb) it started below ground testing treaty talks. When you think of how many of the countries own people were injured or killed in USSR kazakhstan and Nevada... lunacy
@@OAleathaO compared to the SL-1, which had a worker pinned to the concrete ceiling with a control rod bushing. Same flaw in that reactor as was in the Chernobyl unit, a moderator at the tip of the control rods and a positive void coefficient.
Compared to the usual nuclear video, this actually feels kind of wholesome for some reason I can't quite put my finger on. I mean, it's nuclear explosions, and probably contributed to thyroid cancer levels, but I can't help but imagine how fun it must've been for the operators to have the reactors go boom. It must've been like some nuclear episode of Mythbusters!
"three dollars sixty cents above critical" Well it was about that time I noticed Plainly Difficult was a giant crustacean from the paleolithic era, I said "dammit monster you ain't getting my tree fiddy"
I thought maybe someone had told him his was saying it wrong so he re-recorded it, I would say that this video marks the first time he has pronounced it what I would say is correctly in any of his videos.
Well, you have to take all this data with grain of salt. You are dealing with highly classified military projects, whose real purpose will remain mystery. Read inbetween lines though. 1) Tests of getting reactor critical up to point of destruction were made. But those were not real failure tests - in reality such item would be destroyed during re-entry, or in worst case - during impact. So ask Yourself - why they tested how to blow this thing up? 2)Having device wchich could explode in orbit , polluting it with highly radioactive waste is one of elements of setting dominance over space. It is terrorism - play nice or orbit will be defunct for 50 or more years. Touch us and 40 such sattelites will just fall down on earth . 3)Do you really believe it is defunct on graveyard orbit? Having 500W device, able to explode, without any panels (size) sets dominance there too. That is loads of power in a place where billion dollar devices are parked. We know next to nil on military program of graveyard "junk" recycling, but sooner or later something will need to be done - once things will start colliding there, it will become graveyard asteroid belt, useless for thousands of years. Right now it is not possible to put really powerfull devices, like 20MW transmitters to "graveyard", but in 60's they did not know humankind will collapse in endless cold war, culminating with series of pandemics, destruction of goobal ecosysyem and population boom up to 7billion. Look up what was the population on earth in 1960. It was bad, but still offered some hope. They had sci-fi about dyson spheres and colonies on mars. They had no internet, worldometers.info or thousands of nation-state crime copycats building nuclear warheads like there is no tommorow. Marylin-manson was not even born back then, this did happen 9 years later 😅

Being able to go from 500W od design power to 74GW (*way* more then reactor 4 in Chernobyl when it tossed the lid through the roof) shows you just how much power there is in nuclear energy
Weeeell... The actual energy produced at the moment of the explosion is not known, 32-33000 Mw mark was just the last recorded output of the reactor, could have been more and i wouldn't be surprised if that was the case. 74000 is still pretty impressive for a tiny, spacecraft reactor (compared to the huge RBMK from Chernobyl)

@@victr7487 I was thinking something similar. If a cute little 500W reactor can reach 74 GW, then reactor 4 must have reached a truly scary number before disassembly.

I was just about to go off site, but here you are in the comments doing that good work, you sage. Also, well, Actually Question should we all be terrified? Or would the atomic energy coop of the post- WWII era have had the “get under your desk”- atomic school-age kids see videos of all these those 30 or so realtors as more of little satellites? Such as a psa school video to lull them into a feeling of safety. Something with a narrator dub over basic kids looking through a clip art telescope, with an upbeat innovation jingle playing underneath , and him saying: “Hey look little Johnny! See way up there Sally? That’s no transatlantic PanAm flight, no, but you’re close. Just imagine all around you , in outer space, as you sleep, Nuclear power is circling the Earth! Isn’t it just the cats pajamas? Yes, just look up on any clear night sky from the safety of your American homes, and who knows? With the help of a high to medium powered telescope, you might see your friend- Little SNAP, ah yes, what a fella! Would wouldn’t believe the like he has had , and he is only the same age as you boys and girls! But don’t worry, wait to you find out how long he is projected to live! Is he lonely? Poppycock! Would you believe that he is just One of 30 our many brave orbiters, making their nightly trips, check ups I call them, around our world, and especially around the USofA? Little SNAP loves baseball and as he passes his orbit each day, he does so is a an adorable baseball uniform and a small Louisville slugger NASA designed just for him in space, and each night you could see him in the sky, as he rounds third base for what will be another home run on the scoreboard, you can see him sliding into home plate for the all American team! Now get out there and play ball with Nuclear power kids, because if you don’t, the communist will pick up this very bat, and who knows? They might just stay to get good at our game, and the next thing you and I know... they will win! (In this psa vid it shows a baseball/physicist guy swinging a bat and knocking the small test Nuclear Snap device clear into the stratosphere and the 2 kids are at his side looking up in amazement) - I don’t make the rules, I just make this stuff up..

Funny story about that. George C. Scott wanted to play the character of General Turgidson more seriously than Kubrick wanted. Kubrick convinced him to go over the top with his actions, claiming that these were demo reels and wouldn’t be used in the actual movie. Of course they were and Scott, very annoyed at this, swore never to work with Kubrick again.

I just discovered your channel! Great stuff, well researched, scripted and presented. Keep it up, I'll look forward to your videos to come as I gorge myself on your back catalogue :)
I've been a fan of your channel for quit some time, and find all of your content quite interesting. I found this one uniquely interesting as I live in the city of Idaho Falls, which isn't all that far from the test bed (currently Idaho National laboratory) these experiments took place. It's kind of a giggle to myself as the house I currently own was originally government housing constructed in the mid 50's, for naval personnel working out at the INL at the time.
Any chance we could see a video about the SPERT experiments? the Special Power Excursion Reactor Test program had a very similar idea to SNAPTRAN, with the plan of testing the effects of prompt criticality on power reactors. Unlike SNAPTRAN, however, SPERT was intended for land-based reactors. And here's another plug for the USS Thresher and USS Scorpion incidents. Thresher's story has never been properly explained in detail before, and the Scorpion's true cause of loss was only discovered in the past few years.
These all sound interesting. Hope we get them someday. :) And the U.S. subs are discussed far less, at least in the U.S. than the Soviet subs that sank.

Strictly speaking $3.60 is a reactivity measurement not a power one. It means that the reactor was made substantially super prompt critical ($1 is the USA term for prompt critical - the Russians use an alternative symbol). This means that the neutron chain reaction can self sustain and increase on the basis of prompt neutrons alone, i.e. using the neutrons directly produced by the fission of U-235 and without having to wait around for any neutrons produced later by the radioactive decay of fission products. Such conditions would cause the reactor power to surge very rapidly, liberating enough energy to explosively dismantle the reactor in a very short time. I'm going to say less than 10 milliseconds as a rough guess, in which case the reactor would explode much as if it were being blown apart by a chemical explosive.
Can you do a video explaining all the types of unit of measurement used in these videos and their effects on the human body? Curie Rad Rem Rondgens Sieverts Bequerel Culomb Grays Because I don't understand them well and you often switch units between videos for no explained reason. 😐
Number 2 but points at 1. I was thinking about that bit so much I missed the few minutes before that also the giant foot from flying circus through me. I'm easily confused :) Then the old fashioned 3 bars in the top right corner to show an advert was coming up sent me back to my childhood watching tv in the '80 and '90. See I'm easily distracted also :)
I did not get the notification for this video and I appreciate the posts to remind me. I look forward to my usual Saturday morning dose of nuclear chaos.
Well it is just a unit to measure reactivity in a critical mass. A dollar defines the rate of a steady criticality with no increase in it. Like a self sustaining chain reaction. So 2 dollars would be a runaway excursion for example. The more dollars greater than one means more and faster trouble....
7:55 “Due to not having the reflector drums installed, a different form of power control was needed.” 9:08 “All 37 fuel elements and 6 beryllium reflectors were destroyed.” Must be one heck of an explosion to destroy reflectors that aren’t even installed.
Reflector =/= drum The reflectors in question were permanently affixed to the reactor unlike the drums Hence why all 6 were destroyed when there were only 4 drums
Been waiting for you to do a video like this also had another idea for a video how much nuclear waste is in space I watched a few of your videos that’s what I’m thinking right now
4000 years from now humans will either be long gone, or have progressed to the point that all that space junk will have be taken care of. They’ve already started to design (or conceptualize at least) space junk collecting spacecraft. Unless we, as a modern civilization, self destruct. In which case, all bets are off and good luck future humans.
When it's controlled or at lest in a controlled and remote place (ahem, SL1), it provides good data for safety. US voluntarily destroyed reactors -> Three Miles Island is their worst nuclear incident. USSR never recorded anything on their multiple mishaps for secrecy reason -> Tchernobyl, Kyshtym, Andreev Bay...
A big thing here is NaK explodes when it contacts water, just like Sodium metal and Potassium metal. Because that's what it is! If you mix together Sodium and Potassium metal, they merge and become a liquid for some reason. Thunderf00t on RUclips experiments with it a lot, I believe he put it in a car fuel injector to make a highly controllable and accurately dosed explosion-sprayer for experiments 😂
The guy who always stepped on his colleges feet has obviously been replaced. Great to see nasty stuff being tested thoroughly. The Swedish warship Wasa (on display in Stockholm) was also tested and considered definitely not seaworthy. In came the captain: “Hoist ALL sails!!!” .... Absolutely a 10 on the richter scale.
In the case of the SNAPTRAN-2 test, what would have been the mechanism causing the core to explode, rather than just melt? I can imagine that in SNAPTRAN-1, the rapid boiling of the water flooding the core would have produced a considerable destructive force, so would the expansion of air due to heating have produced a similar effect in the second test?
Just thought I would diverge from the usual n say....love the danger fanfare intro and the continuing lack of annoying soundtrack throughout your videos 👍 Love the content also.....bring on the wider catchment areas of disaster

Question should we all be terrified?
Or would the atomic energy coop of the post- WWII era have had the “get under your desk”- atomic school-age kids see videos of all these those 30 or so realtors as more of little satellites? Such as a psa school video to lull them into a feeling of safety. Something with a narrator dub over basic kids looking through a clip art telescope, with an upbeat innovation jingle playing underneath , and him saying:
“Hey look little Johnny! See way up there Sally? That’s no transatlantic PanAm flight, no, but you’re close.
Just imagine all around you , in outer space, as you sleep, Nuclear power is circling the Earth!
Isn’t it just the cats pajamas?
Yes, just look up on any clear night sky from the safety of your American homes, and who knows?
With the help of a high to medium powered telescope, you might see your friend- Little SNAP, ah yes, what a fella!
Would wouldn’t believe the like he has had , and he is only the same age as you boys and girls! But don’t worry, wait to you find out how long he is projected to live!
Is he lonely? Poppycock! Would you believe that he is just One of 30 our many brave orbiters, making their nightly trips, check ups I call them, around our world, and especially around the USofA?
Little SNAP loves baseball and as he passes his orbit each day, he does so is a an adorable baseball uniform and a small Louisville slugger NASA designed just for him in space, and each night you could see him in the sky, as he rounds third base for what will be another home run on the scoreboard, you can see him sliding into home plate for the all American team!
Now get out there and play ball with Nuclear power kids, because if you don’t, the communist will pick up this very bat, and who knows? They might just stay to get good at our game, and the next thing you and I know... they will win! (In this psa vid it shows a baseball/physicist guy swinging a bat and knocking the small test Nuclear Snap device clear into the stratosphere and the 2 kids are at his side looking up in amazement) -
I don’t make the rules, I just make this stuff up..
that there is only one American one and the rest are Russian, makes for better spin and disinformation. I’m going to go with it. Put a small ©️at bottom that says something to effect of “Brought to You by free and total Capitalism and in no way Commissioned by Soviet Outreach of Children’s assessment to very good better Party”
One of the Soviet reactors is scattered across northern Canada. If you're hiking in the Great White North and run across grizzly bears with tentacles you'll know why.
Another wonderful Plainly Diffi-Cult production.
Noo, our foot-stepping hero didn't appear 🤣
They needed a rest to go to a Podiatry health care professional
Happy New Year PD! Here’s to a better year!
Thank you!
The voice overlay made me smile :D
Future earthlings will wonder where that radioactive meteorite came from.
Being the first to send something nuclear into space is... Maybe Dr. Strangelove wasn't as much of a satire as its made out to be.
It was a documentary!
Funny story about that. George C. Scott wanted to play the character of General Turgidson more seriously than Kubrick wanted. Kubrick convinced him to go over the top with his actions, claiming that these were demo reels and wouldn’t be used in the actual movie. Of course they were and Scott, very annoyed at this, swore never to work with Kubrick again.
It was satire? I thought it was a cold war era torture device. Worst movie I've ever seen.
"Ok, gentlemen, we have determined that we need to test crashes into the ocean, in the desert, and in a large city, but the contracts office says we only have the budget for two test scenarios. So, let's decide which scenario is the least important and can be cancelled."
Just wanted to say that the Monty Python foot tribute was awesome and made me LOL. I love your videos and watch/listen to them often. CHEERS!
Thank you
If humanity manages to survive 4000 years, the people of that time will be in for quite a surprise.
Forget the reactor, I just wanna see what happens when a few kg of hot NAK hit a tank of water.
Hell, who *doesn't?*
As a first degree approximation, I'd say... boom?
@@StefanoBorini you are an order of magnitude out. It was kaboom
ruclips.net/video/t9wmWZbr_wQ/видео.html
I just discovered your channel! Great stuff, well researched, scripted and presented. Keep it up, I'll look forward to your videos to come as I gorge myself on your back catalogue :)
Thank you gorge away! Just like how I'm eating my weight in chocolate!
I've been a fan of your channel for quit some time, and find all of your content quite interesting. I found this one uniquely interesting as I live in the city of Idaho Falls, which isn't all that far from the test bed (currently Idaho National laboratory) these experiments took place. It's kind of a giggle to myself as the house I currently own was originally government housing constructed in the mid 50's, for naval personnel working out at the INL at the time.
Thank you for your support!!
very fresh, fresher than the manhattan project in nuclear history.
enjoying binging your videos ,not sure how hard they were to make but based on the quality i can say for sure it was plainly difficult
Thank You for the wonderful videos! I enjoy when you release them.
Glad you like them!
Any chance we could see a video about the SPERT experiments? the Special Power Excursion Reactor Test program had a very similar idea to SNAPTRAN, with the plan of testing the effects of prompt criticality on power reactors. Unlike SNAPTRAN, however, SPERT was intended for land-based reactors.
And here's another plug for the USS Thresher and USS Scorpion incidents. Thresher's story has never been properly explained in detail before, and the Scorpion's true cause of loss was only discovered in the past few years.
These all sound interesting. Hope we get them someday. :) And the U.S. subs are discussed far less, at least in the U.S. than the Soviet subs that sank.
Always looking forward to an upload! Great vid as usual!
0:34 and now for something completely different
Or as nowadays kids would put it: I see you're a man of culture as well.
I love your videos and especially your humor! Well along with all of the information! You are a credit to criticality! Thanks for all of your hard work! Keep glowing like a Radioactive beacon in the darkness of night!
Thanks so much!
@@PlainlyDifficult Honestly, thank you. I also look forward to your Brief History videos. You put a lot of time into making these both funny yet informative. That's not easy. Well plus editing the videos and pictures! Lots of work. Just know that there are a lot of us out here who appreciate your work.
Thus, the reactor goes ＹＥＥＴ.
Graphite at Chernobyl: So, anyway, I started blastin'. Bah! Bah!
ehe
that safty check worked it showed that Chernobyl was not ready for use
9:37 I like that change in voice tone, adds just the perfect touch of sinisterness to the video.
When I think about nuclear-powered testing I think oil company.
Well, if you play fallout, then yeah you really would. Poseidon Energy.
Energy company.
@@RCAvhstape yeah, but you get my point.
50-80s probably the best time to be an American, just living you had a good chance to be part of major history.
Loving the way yourself as a voice over is so different haha. Love all your stuff too by the way.
Good start to the year, keep it up!
Foot steps on thing, fart sounds. Nice Python reference! :D
Also, subscribed a while back, but never got around to telling just how much i enjoy your content! Thanks a lot, please keep 'em coming! :)
Cheers!
You should do the Borax test reactors too!
Thanks for the suggestion
The Borat test Reactors...
My mind betrayed me fastttt
Something tells me this does NOT involve Borax laundry powder. 🤣
0:36 Boomers Remember Monty Python
Thanks for sharing this bit of nuclear-powered 1960s madness!
Happy New Year to PD
Woah. Your best one so far. Keep up the great work.
Thanks 😁
“3.60$ above critical”
If you don’t mind, I will be laughing
Make that a 3.6
The bot must have missed read that bit
$3.60
What bot you doughnut, I'm referencing Chernobyl you idiots, "3.6 Roentgen, not great, not terrible" by Dyatlov
First episode of 2021! Nice vid, by the way!!
Happy New Year, man! I absolutely adore your videos and they are REALLY motivating me to finally get out there and reach my dreams of becoming a nuclear engineer. I LOVE YOU! ❤
What does "power increase to $3.60 cents above critical" mean, keeping in mund my hearing isn't too flash?
Strictly speaking $3.60 is a reactivity measurement not a power one.
It means that the reactor was made substantially super prompt critical ($1 is the USA term for prompt critical - the Russians use an alternative symbol). This means that the neutron chain reaction can self sustain and increase on the basis of prompt neutrons alone, i.e. using the neutrons directly produced by the fission of U-235 and without having to wait around for any neutrons produced later by the radioactive decay of fission products.
Such conditions would cause the reactor power to surge very rapidly, liberating enough energy to explosively dismantle the reactor in a very short time. I'm going to say less than 10 milliseconds as a rough guess, in which case the reactor would explode much as if it were being blown apart by a chemical explosive.
Can you do a video explaining all the types of unit of measurement used in these videos and their effects on the human body?
Curie
Rad
Rem
Rondgens
Sieverts
Bequerel
Culomb
Grays
Because I don't understand them well and you often switch units between videos for no explained reason. 😐
Number 2 but points at 1. I was thinking about that bit so much I missed the few minutes before that also the giant foot from flying circus through me. I'm easily confused :)
Then the old fashioned 3 bars in the top right corner to show an advert was coming up sent me back to my childhood watching tv in the '80 and '90. See I'm easily distracted also :)
Boom!
@@PlainlyDifficult where did my 💓 go? See I don't miss anything :)
Looks like he’s entering into a Zone of Danger 10:15
No no, but how would you phrase that?
@@waharadome Danger Zone! 😂
@@interstellarsurfer Damn you, I'll never get that song out of my head now!
Hey Lana. Lana. LANA!
@@RCAvhstape WHAT!?
Cool vids, geezer! Keep ‘em coming... 😎😎
Thanks! Will do!
I did not get the notification for this video and I appreciate the posts to remind me. I look forward to my usual Saturday morning dose of nuclear chaos.
Thank you!
Could someone kindly explain what the dollars and cents thing is about? I'm kinda fascinated by this.
I think he’s just expressing 360% in a funny way.
@@matthewkriebel7342 The funny people who originally engineered this stuff 'coined' that term. 😋
Well it is just a unit to measure reactivity in a critical mass. A dollar defines the rate of a steady criticality with no increase in it. Like a self sustaining chain reaction. So 2 dollars would be a runaway excursion for example. The more dollars greater than one means more and faster trouble....
@@eaglevision993 I never knew that! Thanks for the good, clear explanation.
So $3.60 meant that it was completely f*cked, I suppose?
Someone in another thread linked to this: en.wikipedia.org/wiki/Dollar_(reactivity)
7:55 “Due to not having the reflector drums installed, a different form of power control was needed.”
9:08 “All 37 fuel elements and 6 beryllium reflectors were destroyed.”
Must be one heck of an explosion to destroy reflectors that aren’t even installed.
Reflector =/= drum
The reflectors in question were permanently affixed to the reactor unlike the drums
Hence why all 6 were destroyed when there were only 4 drums
BORAX TEST NEXT? GREAT JOB
Great stuff! Working at a nuclear researc facility, I always learn something to anoy my bosses over here!
Thank you so much for reading out the PD rating scale number, I finally know what the rating is while I'm driving and can't see the screen
Been waiting for you to do a video like this also had another idea for a video how much nuclear waste is in space I watched a few of your videos that’s what I’m thinking right now
13:15 Wait! Does it mean in ~4000 years 4.7kg of Uranium will be falling down on earth?
Yes. But probably sooner when it gets hit by another piece of space debris and gets scattered into a large cloud of radioactive junk.
@@jamestheotherone742 I'd rather see it get picked up by a starship ;)
Holy
Sh... humanity already did THAT mess too?!! I am suprized no more people find this odd!!
4000 years from now humans will either be long gone, or have progressed to the point that all that space junk will have be taken care of. They’ve already started to design (or conceptualize at least) space junk collecting spacecraft. Unless we, as a modern civilization, self destruct. In which case, all bets are off and good luck future humans.
@@MrMontanaNights Yeah I agree, its that in between part that is tricky.
Destructive testing is always fun, even with nuclear reactors!
I'm glad not to be the only sick bastard here thinking this! You know those guys enjoyed their work.
When it's controlled or at lest in a controlled and remote place (ahem, SL1), it provides good data for safety.
US voluntarily destroyed reactors -> Three Miles Island is their worst nuclear incident.
USSR never recorded anything on their multiple mishaps for secrecy reason -> Tchernobyl, Kyshtym, Andreev Bay...
I find all your videos more then plainly interesting.
Intentional destructive testing is always a win.
A big thing here is NaK explodes when it contacts water, just like Sodium metal and Potassium metal. Because that's what it is! If you mix together Sodium and Potassium metal, they merge and become a liquid for some reason. Thunderf00t on RUclips experiments with it a lot, I believe he put it in a car fuel injector to make a highly controllable and accurately dosed explosion-sprayer for experiments 😂
On my way to work, last thing I get to do, watch a new plainly difficult video! Whoop whoop!
12:01 i thought i had water in my ear but it was just you correcting your sentances lmao
Now this is a great start to a new year; excellent documentary and I wish I could work for you
one wonders what Cornelius will think when that satellite comes crashing to the surface...
"Ape has never nuked ape!"
The guy who always stepped on his colleges feet has obviously been replaced. Great to see nasty stuff being tested thoroughly.
The Swedish warship Wasa (on display in Stockholm) was also tested and considered definitely not seaworthy. In came the captain: “Hoist ALL sails!!!” .... Absolutely a 10 on the richter scale.
SNAP reactor development contributed to the Santa Susana Field Lab being a radioactive superfund site. The 60s were a different time!
Idk why I'm addicted to these vids
In the case of the SNAPTRAN-2 test, what would have been the mechanism causing the core to explode, rather than just melt? I can imagine that in SNAPTRAN-1, the rapid boiling of the water flooding the core would have produced a considerable destructive force, so would the expansion of air due to heating have produced a similar effect in the second test?
Love the lines in the top right to show ads are about to start like on tv
Just thought I would diverge from the usual n say....love the danger fanfare intro and the continuing lack of annoying soundtrack throughout your videos 👍
Love the content also.....bring on the wider catchment areas of disaster
This is how you get through a snowy day in England
I wish it was snowing over here in east anglia! 😭
No snow in my sunny southeastern corner of London
I'm in south Yorkshire id love to be able to post a picture its -2

^ The "experiments" in this video in a nutshell
You have my respect for all the research you are doing in your videos. And I like your good ol´ British sense of sarcasm... :)
those jump cuts with the read oout levels omg
0:36 Nice Monty Python-esque foot of cupid :)
0:06 i dont need to imagine.... my bank statement says it all... and they're fuckin' pissed
"They can worry about it 4000 later".
If society survives 4000 years longer, we'll probably collect that space junk and land it in a controlled manner. Maybe even put it in a museum.
Why does the sudden cut editing of "ROENTGENS PER HOUR" make me laugh so hard?
That explains the huge circular fenced-off areas you can see on Google maps of the western deserts.
Wait, that reactor is still up there?! That's a big space debris!
Great video! If your destructive test doesn't form corium though, are you really trying hard enough?
Three headed antelope are still seen in the Arco and Mackay area.
How come every time you do a video you talk about Radiation levels in different measurements?
Guessing he goes with whatever the source material has as the measurements.
Molten NAK, Uranium and water.....what could possibly go wrong?
