i love how a large portion of human discovery is someone made a mistake.
"someone made a mistake" is just a tiny portion.
Serendipitous discoveries are a minor factor in progress compared to "regular" research and development. You only hear disproportionately about them because they make for popular stories in the media.
But even when it is the case, the initial mistake must first be recognized as being potentially of interest (instead of going straight to the trashcan), then investigated, replicated, and understood ; and only then can you start the whole engineering (and extra research) needed to make it into something useful (if it turns out it can be made into anything useful at all).
Genius is 1% inspiration, 99% perspiration.
yeah and when they go looking for things they get it totally wrong
And not just with humans. DNA and RNA "making mistakes" is how mutations (in the short-term) and evolution (in the long-term) happen.
Sometimes you get good things (like larger brains), sometimes you get bad things (like cancer), and sometimes you get things that are bad with the full version but can be good in the lessor version (Fully expressed sickle-cell anemia's bad, but, being a carrier of the gene can make you more resistant to malaria).
Long story short, not all mistakes are bad.
Well the entire evolution of all life on earth is just a series of "mistakes", so scientific "evolution" often follows the same principle.
yes Rump... thats what I was going to say exactly, nature has shaped us using just one tool, "mistake"
The bucket part had me dead.
Well done SciShow, Well fucking done.
Look into CCD's, and you will run across another bucket analogy. In the case of a CCD, imagine a bunch of conveyor belt with buckets on them, all feeding into another bucket filled conveyor belt. This belt feeds a single bucket that is used to measure the contents of the previous bucket on the belt feeding into it. once all conveyor belt are emptied, you can then put the numerical representation of the buckets contents back together into a representation of the bucket array. Thus creating an image.
Another one is analog solid state reverb, where you have a bucket chain that moves the signal from the input to the output, the time it takes for the contents of a bucket to get from one end to the other is the delay time. (when combined with a un-delayed signal you have a reverb effect)
I could give you a few more bucket analogy's if you want.
Oh, God, so many buckets! Aaaaahhh!
I'll never be able to unsee that.
Mkay good I'm not the only one who found that funny 😂
Kevin Like the first episode of Rick and Morty season 2 (GIVE US SEASON 3 ALREADY) all over again eh?
Has science gone too far??
2:11 I want a shirt with that pattern of Hanks passing buckets to other Hanks.
the bucket scene was the best moment in my day
It belongs in a GIF and/or on SciShow merchandise.
Exhibit A: 2:00 to 2:10 of SciShow video titled "A Plastic That Conducts Electricity?". This section of the video shows the early stages of the accused's [Hank Green] production of identical androids with hive-mind tendencies.
Napalm HS lol
Clone wars: Hanks vs Craigs? I honestly would watch that...
The Hankening
Napalm HS everyone submit to our all powerful robotic Overhanks

That duplicating Hank thing.... was mesmerizing.... Hank truly is the bucket god.
I fucking loved the editing in this episode. XD
I like the way this video edited.
Claude Faust Thank Josef "Tuna" Metesh lmao
yes
That bucket scene was not only entertaining but really clearly explained the concept! :D I love that they decided to edit his voice in several times over as well to really sell the scene.
Hank is an awesome teacher. :)
An Undefined User ( ͡° ͜ʖ ͡°)
how do you accidentally add a 1000 more of anything
Probably thought he was supposed to add kilos instead of grams or something.
Noodler more like he was supposed to add nanograms but added milligrams instead
Noodler that's kinda bullshit, he was in a lab, not a factory. Experiments aren't done with kilo's of chemicals but with milligrams or grams
It is possible tho, that he used grams instead of milligrams
Tim Allan.

Basically SciShow's Funniest Moment 2017.
loved the bucket analogy combined with the visuals..keep up the great work
I swear every time Hank hosts a video, it has some form of weird entertainment in it
I can't stop rewatching the bucket brigade scene. It is so amazing; I love it!!
Hank Green continue what you're doing!
I've worked on this for years at the energy research institute of The Netherlands. Awesome video!!
This is one of the most interesting video's you've made in a long time. Wow, just wow.
I love the editing in this video
I really enjoyed the bucket bit, very entertaining. Nice work.
Awesome! I loved the multi-Hank bucket simile! SCI SHOW RULES!
What I learned from this video? If you accidentally make something great, never tell your teacher, he will steal the idea.
That demonstration with the buckets was beautiful.
I have to give a big kudos to the editors, to you guys I give my entire apreciation for making those videos funnier and much more enjoyable
I thought I had a stroke at 2:00
perfect editing. On point. 10/10 would bang again
If you listen closely, you may be able to hear UA-cam's compression algorithm hyperventilating when the screen suddenly fills with Hanks in extremely busy patterned shirts :v
*dying at Hank multiplying into a dozen Hanks
Microscopic Bucket Brigade: Hank's new band w/Michael Aranda & Matthew Gaydos. =D
The multi-Hank editing on this video was wondrous.
LMAO! Love the bucket analogy. Cool video
awesome explanation man
Hank, keep on hosting, you're a legend
There is also conductive rubbers(usually silicon based). One app of it is connecting to LCD screens in digital watches, small game toys etc. It is composed of alternating strips of conductive and non-conductive rubber. A home made pressure sensor can be made using this because with pressure the resistance changes.
Hi there, SciShow! I would love for people to learn about the terrifying and sudden nature of cerebral aneurysms! I had one rupture at 19 and I think it would make for an interesting video topic!
Awesome video! It would be cool if you guys would talk about piezoelectric polymers sometime. Those are super cool.
AYYYY! I'm excited! I have been doing research for 2 years now on polymer based solar cells and now they are getting their own spotlight!
2:10 I need that background as a screensaver XD
I like that upgrade in editing. the bicket segment was pretty funny
Darn, the editing is much better!
We use a black conductive plastic housing on one of the parts I work with. It conducts about 600VDC in operation. I took my multi-meter to it once to check its resistance but it showed an open. Guess its only conductive at high V
Tuna, I love ya man. Great graphics here~
Bucket-ception.
to whoever did the bucket editing, kudos.
I really love your shirt! Cool video
it's going to be a scroll with retractable borders that stiffen the screen for a certain distance... and they will prolly give you an extra amount you can pull out for a sidebar style menu with pins and notes. all rolling up into a pen sized device that houses the rolled up screen, all needed ports, and a smaller pen to detach for use with the scroll while extended... its going to be awesome... it's so obvious to me lol.
and the army of Hank Green's have begun
this editor is fun! please keep him!
How do you accidently add 1000x a catalyst? Like that sounds just a little bit more than a "Oh whoops" situation lol.
It was probably measured in micrograms (or just a really small measurement), so a little droplet can literally be 1000x more than what it's supposed to be used.
TheFanciestBard exponent confusion, milli vs micro for example, or cm3 vs mm3 in measurement. And why is kilogram (1000g) a base unit instead of the logical gram?!;)
That one study about caffeine where they accidentally gave the participants 100 times the intended dose putting them in significant danger
TheFanciestBard well if the mixture called for a milligram and you add a gram of something, which isn't much, you have now added 1000x more catalyst.
By getting your metric wrong, that's how. Well, each prefix is 1000 times more (or less, going the other direction) than the last (except for centi and deci).
Came here looking for an answer to how you could apply and conduct charges across plastics and was not disappointed: Plastic polymers.
Interesting that it was invented by total accident and has revolutionized several industries.
Hank, you're a prophet and didn't know it! We have folding phones. The future is now!
Nice explanation
Props to the editor for this one
I lost it on the bucket part... omg XD
You might want to recheck your facts. The Ransburg Number 2 Process Electrostatic Paint Gun has a schematic dating 1961, which has a plastic bell that transfers 90,000 volts positive to the paint. If this bell is cleaned in laquer thinner or MEK, it will strip too many electrons making the bell almost useless. So, they are cleaned in xylene.
A+ editing
Thank you too so much@! 🐶
what a godly editing for bucket
Please put hundreds of Hank clones in every video, we need more, Hanks!
Why is there a bucket around my-
Nvm it's the toilet.
I liked the editing
I think SciShow should make an episode featuring "accidentally awesome" mistakes in chemistry, things like conductive plastic and Teflon.
Haven't there been flexible screens for a while now? For example in those phones where the screen wraps around the edge? I was under the impression the limitation for bending phones right now was about their internal components.
2:00
Never fear, the Bucket Brigade is here! =D
I like how the show is evolving
3:10 yeah... that's right. Researchers have to HACK printers, because none of the large corporations have yet opened up anything with regards to inkjet tech. Everything that exists and is usable is an HP cartridge printer that someone managed to reverse engineer. Otherwise you'll have to go with some real expensive industrial print heads, and good luck getting those working without spending tons of money.
My point is, I really think there's a market for an inkjet maker kit, where you can experiment with different nozzle sizes and have full control over the head. This is not going to happen any time soon though, HP Ricoh and Epson are way too worried of innovation that isn't completely locked down.
top quality editing five outta fove
love hank green
wait...if you sit on a voodoo doll of yourself does that mean you will be infinitely stuck ?
cant influence your own voodoo doll or something
The scientist had to be knowledgeable and enough of a creative thinker, to extrapolate the potential uses for this " mistake" - and follow it up with learning even more about chemistry and electronics, couple with countless experiments, failures and much tenacity and teamwork.
That is the way of most so called breakthroughs in science and medicine.
Enjoyed videoooo!
"bendy smartphone" oh John you think to small. AR is on the rise to kill the smartphone.
Why did the bucket part make me laugh 😂😂😂😂Someone tell me why the heck is it so funny to me😂😂😂😂
the bucket thing is sooo cooooooooool!!!!
Whoa, those are some shocking results....
i love hank
Last time I was this early there were no anus jokes
what the actual fuck was that AMAZING editing with the bucket example :D That was the best :D
Good job.
Thats really interesting
What surprises me about this whole thing is that it took almost 30 years for the group of scientists who invented conductive plastics to be formally recognized for their work....
Whoever edited this episode of scishow is hilarious.
Where did you buy that shirt Hank?:) love it!
When you want to pass your bucket but everyone around you already has buckets
I love the bucket-acid-trip you tossed in there.
And what is that black rubbery material on the back of button sheets that touches the circuit plate? I thought that's also plastic
If my team invented a conductive plastic, my first move would be to show it to Emperor Palpatine too.
Can't wait for my solar powered rucksack!
Start with a flexible plastic solar cell powered charger ;-) infinitypv.com/products/heli-on/heli-on
Really enjoyable show! Did he say "on accident"?
@SciShow....Back in 1991 in computer science class in college they were talking about plastic ram and plastic hard drives.What ever happened to that stuff. Also we were told that someone was working with biological transistors and other biological computer components. I haven't heard anything ever coming of that stuff but would love to know why.
How about taking apart some stuff and showing us where to find some of these conductive polymers and diferent looks and styles they might have
bendy smartphones: bad
smartphones whose components can handle an impact: sign me tf up
Hank Green for President !
So many buckets!
why didn't the person who accidental made the plastic get any credit for the descovery?
We have conductive plastic, now we need transparent metal. Aluminum seems like a good contender.
Wait *someone* in his lab accidentally created the base for the material and *he* got the Nobel price? Did I get that right?
yeah. Maybe its because the person who accidentally made it never worked out how it works?
Or the lab head just stole it :/
He figured out how it worked so it could be replicated and improved. That's what the prize was for.
BTW if your use your job's or university's resources to invent something they can claim rights to it.
+Ides385 Damn...if i was ever in that position i would hide the decovery and later release it on my own claming i only used my own resources.
+darkfight light No you wouldn't, because you couldn't. We need each other. We all have different expertise and come up with different ideas. One person doesn't suffice. If those other guys never helped I'm sure this discovery would have come much later.
+Squiddi I would. I am greedy/petty and absolutely hate getting screwed over.
4:05 lol we already have bendy phones. They're known as "iPhones"
wow! easy on the shirt there hank.
Hank "multiple buckets" Green
almost there...Marry this to transparent metal, and flexible glass, and you now have a complete system. (All are doable, hang in there! You're sooo close)
First time I'm so early on a SciShow-video...
hey guys!
hello
Hold all the buckets! xD
