I can't be the only one who felt so goddamn proud of humanity for coordinating tasks that spread across so many generations all in the name of science.
I feel so godamn proud of your avatar :^)
I am standing proud because of your avatar.
Wait where's the avatars from. Like is it from anime or what?
Its a sexy shot of Samus Aran from metroid.
Yeah. Whenever you're feeling disappointed with humanity, just come back to this science channel and remind yourself how cool we are.
5:44 "the ninth drop though fell in 2014 and it was caught on camera" proceeds to not show the video.

i walk past it most days when i am on campus - i've had lectures in the theatre next to the experiment
Can't they keep pitch under higher acceleration e.g 1000m/s^2 to make the experiment faster.
Hello
Or the bell, or the microbe cases, or the seed jars... Zero payoff. Could have gotten almost as much visual information from a podcast.
I came to watch hank... Not sure what you all came for.
9:49 the happiest "we'll all be dead" ever said
Not unless we get to building robotic bodies and digitized minds first!
William Perina but would that still be you? wat part of your body makes you you.
What's left is our collection of experiences stored in whatever method we come up with to save our volatile memories from disappearing. It's already clear that some people don't care what they originally looked like with piercings and plastic surgery so maybe they won't mind a robot body.
What would be even cooler though is growing an organic body in a lab or with 3D printing , but that just seems too far off.
I don't know if you grasp what i am talking about. You are saying that only our memories is wat makes a person a person.
What counts as a self being.
If i would teach a machine every thing that is me who i am is that machine me or is it a clone? Does the clone continue as me or does it continue as it's own being?
A good example are identical twins they are born out of the exact same DNA strands but they are still both a independent being and not just one person with two bodies.
Well we're getting very speculative here now. The way I understand how digitizing a mind is that what memories you and I have are volatile. Once cut off from a supply of energy, you, your master copy of yourself, is gone. So to move a mind from an organic body to a non-organic one that old body would either be connected to the new body briefly or the old body would simultaneously die as the new one is activated.
And I thought my lightning glass experiment was taking a long time...
Cody'sLab I guess you were wrong
Cody'sLab hah, yea
Cody'sLab can you capture lightning in a bottle? when you turn the high voltage generator off but keep the vacuum at a full vacuum, will the electricity stay in there like a new version of a battery like in my visions??
Cody'sLab marry me?😗
Hello Cody's Lab, I love your videos, especially the metal refining series. Keep up the good work! :)
"E. Coli experiment started in 1988..." Hey that is the year I was born! Woooo
"Nearly 30 years later...." Oh.... damn I'm almost 30.... :(
The guy who started the experiment must be almost retired...
+Kanglar It was acceptable in the 80's.
I was born about a month after the Chernobyl disaster. It was a bit weird hearing people talking about it last year, saying it was 30 years ago.
How did that happen? I could have sworn I was 25 a few days ago
30 isn’t old age
That was the happiest i've ever heard someone say "we'll all be dead"
Houston Paquette I
There we go
Scientists: I think we should shut down the pitch experiment, it's useless no-
Pitch: PRANKED
I was so excited to see Lenski's research mentioned! I saw him give a talk a few years ago about all of the different things they have learned from the experiment and it was pretty incredible. Hopefully someone continues it after he retires.
"My never ending search for a girlfriend" is the longest experiment ever.
Nice, One!
I remember reading about the Lenski experiments in a Dawkins book ("The Greatest Show on Earth", I think), and wondering why it isn't more famous. The citrate adaptation is a clear demonstration of so called "macro-evolution", which some people still claim is impossible.
Lenski's work deserves a lot more attention than it's gotten. Good on you, SciShow, for giving it some.
While I agree that it's a great adaptation, I fail to see how this is a macroevolution. Is it not still E-Coli?
@@AntonioDoukas That's just the name given by the furless apes who study this bacteria. If scientists had discovered two different types of vibrio with different cell digest capabilities, they would be likely to classificate it as different species.
Creationists keep moving the goalposts. Once macroevolution was proven, now they say evolution of species turning into different “kinds” of species hasn’t been proven, even though they can’t define what constitutes a “different kind.” Clint’s Reptiles has a great explanation of how they keep moving the goalposts no matter what anyone shows them.
I think it's safe to call the battery experiment a success and crack that thing open. Get these batteries into cell phones pronto.
Flintstoned they wouldn't last that long it was the length of time that was surprising not really the density of the electricity the bell doesn't use that much
Nick Pearce That's what we got Elon Musk for right? He can figure it out and make them with more electricity.
This sounds like solid science, Elon Musk hire this man.
$5 bucks says the container is filled with a deadly gas that will kill the researchers and the secret will be lost forever
TheRedKnight $20 they start some kind of human disaster
"We'll all be dead," Speak for yourself, Hank. I'm gonna live forever. Or die trying.
Here's another longest experiment.: how long it takes to buffer this video on my shitty Wifi!?
I feel like the never ending experiment concept is what space travel will eventually become. I'm curious what other people think of this?
There is definitely some merit to that. You have to consider that every mile traveled is essentially two, if you consider the trip back. The further you get, the more likely the need for intergenerational trips will be. Which brings up a whole bunch of other issues.
I want to see people living off the earth. No need for a return trip, and also how well we could live in environments other than earth.
angeldude101 Do you think there would be enough volunteers to uproot their lives and leave the planet? I would love to see scishow cover the topic of living in space. (If they haven't already)
+60 Second Success Based on Mars One, apparently.
Wow, isn't that neat, I just looked into. I would be curious to see how humans on mars would evolve differently from humans on earth.
longest experiment: how long will the universe survive
well I mean there are calculated estimates to that as the universes survival (depending on your definition of course) can be looked at as how long untill all matter decays into heat.
Cool story, bro
Approximately 1 googol years, after that, the universe will achieve thermodynamic equilibrium (“heat death”), and nothing will be able to happen after that. There’s a cool website that has all sorts of countdowns. Including the universe’s heat death
neal.fun/progress/
well we're 6000 years in so far and sky-daddy still hasn't returned to save us all.
Longer one: Door in minecraft that only opens after the universe dies of heat death.
"Every 25 years" I can only imagine the scientist's kids (and so on) make a life milestone out of checking those vials. Twice, maybe three times in life. Here's lookin at you kids!
That electric bell thing sounds like an SCP!
"We'll all be dead"
-Hank Green, 2017
Yeah it’s cool to see how long the bells keep ringing but it seems worth cracking them open in my opinion. If there is something to be learned about optimizing batteries I think it’s worth the sacrifice of watching something cool. Just make another once you know the trick.
No no no, we were assured back in the '90s that if we lived to 2020, we'd live forever.
Its true, look, here you are immortal forever. Congratulations.
Man I wish those fools in 1519 had done some 500-year experiment
You can thank the church for that.
Perhaps they did and it's just been lost to time
@@defenestrator3900 Or they did and it's staring us in the face. Read Umberto Eco's Foucault's Pendulum.
"We'll all be dead!"
You sounded almost scary cheerful saying that lol
Just to be on the safe side shouldn't they brief Keith Richards so he can check up on it?
500 year long experiment eh? Really banking on human civilization lasting that long.
Connor Reynolds It’s gone 10,000 years, I don’t think 500 is a stretch at all
It won't.
Summer Brooks you on them dark arts bruh
@@groovegnome Yeah, bruh, as long as it is associated with real science.
Some churches took longer to make than that. Assuming you’re American 500 year really ain’t that long haha. It’s like 5-10 generations.
Love that in your weeds part you showed purslane. It is very, very edible and yummy kind of like spinach. It is also great for livestock, like chickens.
Can't believe this episode is a year old, and I somehow missed it until now. I think this is one of the best ever.I love the idea of long-term studies, because the data is so rich. My mother participated in a ten-year study in which they determined, at the end, that an extremely low-fat diet is bad for your health.
The files for the best battery ever were "lost" >.> convenient...
Nah, it's pretty inconvenient, actually
TheGuysThree "best" ? probably not, longest running ? yes
Well, there are some speculations of why that battery lasted so long.
The first one is that it is in a vacuum, meaning that there is less energy lost in friction towards air molecules.
The second one is that electromagnetic fields are recharging the battery a little.
Since it is a metal bell, the heat it generates will mostly be conserved in itself aswell, which helps electric currents to be more efficient. There are so many possible factors that could be included, there is no telling what yet.
As for the files missing, there are actually a lot of experiments and items that we cannot simply recreate due to missing files. Experiments and files tend to be seperate, because if one burns down or gets stolen, you can still make the other again from the surviving one. If the original files were burned down, we can easily recreate them by opening the sealed case.
The blueprints were last seen in the hands of a bunny wearing pink sunglasses and flip flops....
Predated “the heat it generates will mostly be conserved in itself as well, which helps electric currents to be more efficient” Weird that people spend billions of dollars on cooling electronics
Really interesting video! Thanks for sharing. Id love to see more historical experiments explained like this :)
Oh, you broke my bubble, I thought I would live forever and see that ending!

Yaakov19 ... did you watch the video?... It's an illustration of one of the experiments...
Imagine if the people 500 years in the future watched this video
This was actually really really interesting. Thanks
Awesome topic for a video. Fascinating! Thanks, SciSchow!
9:46
dont count yourself out yet hank, you're young, you stand a good chance of riding the wave of longevity
Imagine your phone battery last a 100 years. That would be fun
Good to know that Mallow can last for literally ever and still sprout.
I never thought of this sort of thing, but this is really cool.
Let's try an experiment here. Longest comment thread on UA-cam.
Dr.StickFigure it only goes up to 500 replies right?
Dr.StickFigure sounds neat, hope it works out
You wanna experiment with another long thing?
sure lets try
haha
how about taking a look into it with pulsed neutron radiography? Then you would know what is in there and in which proportions
Had to pause the video temporarily to get my food, and I paused in while Hank was making a very flattering face.
Always interesting, thanks.
my dude, uni of queensland, weird liquid metal thingy? Ive been there. can confirm it is slow... VERY slow
UQ represent!
Same here! I see it every day on my way to class :)
I'm a physics alumnus of U of Q, and now feel very old that the now 90 year old experiment was a little more than 50 years old when I started there. I was around for the fall of the 6th drop, although of course I didn't see it.
Quite surprised that the Park Grass experiment wasn't included!
Oh my god so good. Keep it up please!
The original pitch drop experiments were devised by Lord Kelvin in Glasgow University (where a demonstration piece he set up is still running) in the 1880's. There is also one still running in Edinburgh as well as Aberystwyth both of which pre-date the Australian experiment.
Michigan State University appears twice on this list! (seeds and e-coli) Go Green!!
Go White!
Go donate $0.10 per month to me
Go Michigan State!!
2514: "Geeze, I cant believe we ever used glass"
That bell has enveloped the spirit of the energizer bunny
The Oxford bell is powered by Zamboni dry piles. I have an old physics textbook, the 1892 edition of Elementary Lessons on Electricity and Magnetism by S P Thompson. In a chapter discussing types of battery in use it mentions that the Clarendon laboratory bell powered by a dry pile of Zamboni had been running for over forty years.
9:51
He’s glad
What about that Russian fox-domestication experiment?
i need a pet fox
^^^^*NEED*^^^
Dylan Grych you can edit comments
That was intentional, it helps imply emphasis.
Dylan Grych They're adorable.
i was reading about the pitch drop experiment last year and the whole thing is just freakin awesome.
Really loved this video.
"We'll all be dead ... =) " lol
The longest experiments seem to teach us the most.
PROgrammer8 Not really though.
Were gonna be digging up another bottle soon damn thats gonna be cool seeing the bottle again
this has been ( for damn sure) one of the most interesting episodes i've watched.
this comment is an edit that wouldn't be if i had waited to comment till the end of the episode. Some shows die. this'un gets better.
No....no zombies just social distancing and corona quarantine
We have famine,
We have diseases,
We're in an energy crisis,
and what do some of our smartest scientist do?
Watch asphalt drip... COME ON, MATES!
dragonboy123000 You say this as if every fucking scientist is doing this.
crazyguywithasword Obviously not...
I'm not that ignorance...
I was being sarcastic...
Seriously, Hank even said, they were video taping it...
You don't exactly have to be Einstein to rewatch a recorded video to figure out the drop interval...
Some more episodes discussing each of the other forces would be interesting. I'm especially intrigued by how gravity affects space-time.
These are all pretty neat experiments, and as an Otago student I have to do a little plug - I think it also would have been pretty cool to mention the Dunedin Multidisciplinary Health and Development study which has been running for over 40 years now (and shows no signs of stopping).
Wasn't the first battery invented in fucking ancient times? those clay pots that would shock you if you touched them?
Maximilian Russell , No.
Those Baghdad "batteries" only had one "electrode", so they were pretty shocking useless.
Maximilian Russell, there's a possibility of ancient batteries, but nothing so powerful. The earliest batteries (if they really were batteries and not an accident in food storage) could only produce about half a volt...
There were also some antique jars that could shock you on a touch. Those were Liden's Jars (not sure of the spelling)... And they were actually the earliest capacitors. It's fairly easy to look up and even build one of them yourself. I did once for science class out of a gallon-size pickle jar... hilarious! :o)
Schwab sounds like a baby saying their first word
Related to this, id love to see a video about cool experiments that end this year
great episode.
Hate the intro, it is always to loud!
But the content is amazing!
Jakob Wolters the intro sounds fine to me
Went overboard and tested this by recording it in audacity with my sound card and running it through ReplayGain. The intro and the first 20 seconds of speech are at almost identical in volume (the speech is about 0.1dB louder).
What device were you listening on?
Subjective hearing doesn't change the actual volume of the sound. Something 110 decibels is still 110 decibels, even if a deaf person can't hear it.
I'm with you on that. But I find all intros unnecessary and annoying.
I could live with a simple "Hello!"...
I Heard That A Plant Seed Was Trapped In Permafrost Since 9500BC, After A Arctic Squirrel Buried It But Forgot Where It Was, The Seed Was 50ft Under The Surface When Scientists Unearthed It, They Planted It And It Grew Into A Narrow-leafed Campion.
This Is The Oldest Seed Ever To Grow Into A Plant.
Awesome video!
In The Hitchhiker's Guide to the Galaxy, the whole Earth business is as an experiment.
these 6 longest experiments took just long enough to cover for 10 minute ad revenue ;)
There aren't any ads in the middle so there's no extra revenue. Ignoring the "If it's 10 minutes long it's just for greedy ad revenue.
Hey, gotta do what it takes to survive the adpocalypse. At least they put actual content instead of just putting up a picture for 3 minutes
@@littlechickeyhudak I don't understand how there are still people who don't use AdBlock. I forget youtube even has adds until someone mentions it.
This should have been an HFS episode.
An HFS on experiments is on our list!
lol HFS replied
Best one in a while. Nice.
LOL. I love how the script for this episode ended with hank excitedly pronouncing that we will all be dead.
before i continue to watch let me tell you the longest experiment in MY opinion and what i think is. The pitch experiment, you know, the dripping pitch one, the most viscous fluid in the entire world
What wouldn't they open the cylinders? Don't they understand how important it is to improve our battery technology?!
It's not really that important, yes it can sustain electricity for a very long time, but the actual capacity of the battery is very low.
1) The batteries last along time but they are not producing a lot of power.
2) They already have a pretty good idea how the batteries are made. Modern tech can produce higher energy density batteries than these can.
Here‘s another long-running experiment: Cryonics! Already running for several decades in two locations in the US, and more recently also in Switzerland, China, Australia and Russia.
that last statement about free science in my subscription made me subscribe... can't wait
am i supposed to yell daaaammmnmm
Do one on Deja vu no one really knows about it
TheCambobsherwood
I felt like they did a video about that before

SciShow
Well hello there!
Hank, with a smile on his face, "We'll all be dead!" Love it! It's so Rick Sanchez.
Some of your shows are about explaining science to non-scientists. This show was for the scientists. Gorgeous experiements!
No. 5 is for those who still believe evolution is a lie...
So if a car was parked on pitch, it would slowly sink...?
Jack Timothy probably quickly as a car is very heavy
gregistopal not really, it would still take years
Cars in parking lots make dents in the parking spaces where wheels usually sit, so yes
That is how practical scientific experimenting always is.
I like science so much. Amazing to hear how experiments can last so long!
I can't wait to see the results of that 500 year microbiology experiment!! Can't wait! Not long now! :D
if im from future 26th century how u can tell i will be dead
The Pitch Drop: so its a similar to glass? That it looks like a solid but isn't?
In school I also learned that glass is a slow-moving liquid but this is actually an urban legend. Consider that there is plenty of ancient volcanic glass all over the world which has not puddled in the least since it cooled millions of years ago. For more details see www.cmog.org/article/does-glass-flow
thank you very much Karma!
It's funny that you chose a picture of purslane when you were talking about weeds. Purslane is an edible plant that is quite nutritious and makes great salad or light munchings in the garden.
I dunno if you'll post a video today, so happy birthday here Hank!
He started making his voice pitch weird when he was talking about the pitch.... classic nerd jokes
#1 is an SCP
Timpin D. What I highly doubt scps where thought up 177 years ago
Pirate Bear
No but in universe scps have existed since before the universe even
Ryan Maldonado
Which one? SCP-001 or SCP-343?
So... we've literally seen evolution happening in real time? That's super neat.
I’m calling it. If the microbes are still alive and kicking in 2514, there’s no way they won’t extend it to 3014.
the battery is an scp.
I think its amazing scientists rather watch and see how long a battery will last rather than crack it open and potentially discover a source of energy that could change our world.
I think if they really thought they'd learn something important, they would. We already know that it lasted a really really really long time.
The battery although amazing has been doing a rather simple task, researchers could crack it open and figure out that our current technology is far superior and there is little to learn from it. The past still has much to teach us but I doubt the battery is any better then the ones we have today.
As a scientist, they are obligated to see the END RESULT of their experiment.
It might seem ethically useless, but for measurable data is an important point.
Let's just say there were 5 other battery experiments going along with this one, all died out within their set perimeters, and this one is still going on, the scientists in charge will want to see what the eventual outcome of this outlier really is.
I said it was amazing, not that I didn't understand why.
They are either stupid to leave it in favor of learning, or afraid not to understand how it was build after cracking it!
I was officially a witness of the ninth drop of pitch touching down! I got a certificate and everything! :D
I would say that the Grant study with Darwins finches on Daphne Major was a fairly long study, but this was still an interesting video. Thanks! :D
longest experiment ever is life
I like AA battery's the best
The "Time Pyramid" is a work of art under construction in Germany. It will consist of 120 blocks where each block will be placed in every 10 years. The construction began in 1993, has 3 blocks until now, and will finish in 3183!
There is the Beverly Clock that was made at the University of Otago in 1864 and is still running, without ever being wound up. I am not sure if that is still an active experiment though.
