[@ed_weird]

My phone screen needs this.

[@thomasverhey5037]

Ed Weird ifixit, just fix your phone.

[@ed_weird]

Changed the touchscreen 3 days ago. Cracked it the most stupid way yesterday - was going up the stairs, tripped a bit, and grabbed the railing with my hand to keep balance. Too bad my phone was in that hand.

[@DarthObscurity]

They have this on screen protectors. I didn't believe the guy at the cell phone store but I gouged it myself and it was gone the next day.

[@theinternetstolemysoulbuti2740]

Ed Weird You can try putting Neosporin on it. Neosporin has always helped me when I needed to heal.

[@catsoften]

Ed Weird my friends brain needs this. just don't use it in his mouth after I tear it off.

[@angiewagner9232]

I like this host a lot, he's doing a really good job.

[@killclancy5758]

this guy moves his hands just the right amount

[@HDCybersun]

Seems incredibly distracting to me.

[@CrimsonJoker641]

Wow now, that you brought the attention to it, seems too much waving for me.

[@pet3590]

Only matters when you point it out

[@GraveUypo]

haha i got the reference.

[@cantstumpthetrump5987]

clancy scanlan better than ms valley girl

[@SrgtBarney]

can...can i have self healing self-esteem

[@stephanieg2887]

SrgtBarney its knowing your worth and not letting yourself maje you feel like less✨💕

[@YiGzit]

Stephanie G cringe

[@samuelberhane7478]

SrgtBarney how can your self esteem heal if you don't have any in the first place? 🤔

[@catsoften]

SrgtBarney no

[@pranamd1]

Self-esteem is self-healing by its very nature.

[@RandomPerson-br4jh]

Hank looks different

[@catsoften]

yeah. He kinda looks like a man now.

[@maxpayne438]

Zheeph Rose nope, hank speaks with micropauses especially last year (go listen and you'll notice, it bothers me because my brain kinda stops waiting for what is going to say next)

[@PaniaAthea]

+

[@LKAChannel]

still can't heal my broken heart :(

[@ridjf]

Not yet.

[@Unicorn1231997]

LKAChannel lol

[@kys4s4c]

They should invent a self healing heart cause I'm too lazy to heal it myself.

[@calebellis7295]

all around me are familiar faces...

[@abalrog42]

no expressions...

[@GigaOtomia]

I'm a fan of the new host. He varies his tone of voice, so he's more fun to listen to, and you can instinctually tell which parts of his sentences are more important. Helps people pay attention.

[@Ryukachoo]

self healing paint to prevent rust? PLEASE MAKE THIS INTO AN UNDERCARRIAGE AND SUSPENSION COMPONENT COATING FOR CARS PLEASE

[@NightcoreLabOfficial]

If they were able to make cars self heal, it would be chaos

[@JohannesWiegerinck]

As if the Auto- Industry would ever allow for one-time-only tires purchase...

[@CujoHyer]

Exactly. Technology like this will be for the super wealthy only.

[@Lttlemoi]

These car tires will still wear out just like any other regular old tire. This new material only helps fixing when you drive e.g. through glass or sharp rocks.

[@kayar8463]

Yeah, it only stops punctures, not wear and tear.

[@only20frickinletters]

But capitalism is efficient™

[@timoschneider5915]

17inchcorkscrew no its not. otherwise leica would still exist.

[@MatrixTheKitty]

when stefan said "help those lonely pairs bump into eachother" he sounded so forlorn

[@AlexxAmadeo]

I like how his voice started to tremble a bit when he talked about 'lonely pairs of ions'. LOL

[@ExplodingDarth]

captions on point! good job whoever did that I greatly appreciate it mate.

[@Nomad2001]

Now if only they would make a bong that fixes itself when it breaks

[@foofoo1445]

I see many self-repair materials are one-time use only, as in if that part breaks again, then it don't self-repair again. Maybe better materials will emerge in the future, but for now, "lasting forever" is only a dream. Maybe it'll last 300 years, but that's still not "forever".

[@marioavila7618]

It is in your lifetime

[@galaxymel18]

Squash Gaming Exactly. If every person only needed 1 set of tires their entire lives, that would be amazing.

[@patrickmccurry1563]

But it can heal numerous times just not the in the exact same place. But we can't either. Our bones can only heal so well and so often before things get screwy. If that works well enough to keep us operating for many decades of continuous use...

[@Lttlemoi]

The car tires still wear out like regular old tires. This self healing doesn't stop this because tire wear is quite literally due to the road slowly grinding away the rubber, not cutting it into pieces, which is what the self-healing rubber heals.

[@nerdlingeeksly5192]

Quemael Foo in order for something to last forever it needs to constantly recive resorces to use like us but the tire that healed with heat that could last forever you just need to stay off it for a bit and its as good as new

[@MisterPiggyFace]

Why wouldn't we make plastic more invincible?

[@4tonnesoffury329]

Because the bonds are physically not strong enough.

[@Licorneenragee]

Now just imagine Nokia phone made of that stuff!

[@OhighOSkater]

Videos like this are why I subscribed. Very interesting

[@ginawoolsey987]

Can you imagine how many tons of rubber we would eliminate from the environment if we use the self healing rubber for car tires? It would pretty much eliminate the need to get new ones if it broke, so we could just roll into the shop to get it fixed, rather than replaced. Tire burning, gone. Tires on the side of the road, gone. What a great concept.

[@Jason608]

The military has been using this type of technology, for example in self-healing fuel tanks on aircraft, for decades. It would be good to see more of this in civilian applications. Self-healing oil, fuel, radiator, and hydraulic lines would be nice to have in your car.

[@alemon4480]

I really like this guy

[@genjishimada9304]

I NEED HEALING.

[@sabotage7369]

The self-repairing fabric has already been finished, but it's used for clothing so far (jackets and backpacks).

[@catsoften]

1:52 I hear sadness. Somebody wants that lonely pair to come together again

[@agbook2007]

This is a very interesting video! Nicely done!

[@liamcullen3035]

Thanks for the great video! :D

[@PixelleHearts]

Is this basically similar to the concept of shape memory alloys that are stimulated to form different shapes via differences in heat, except with the areas of stimulation being the loci of repair and damage? That's amazing if so, because we can start covering all of our bases with materials now.

[@kazimhussain2045]

Even after all this, Genji will still need healing.

[@z-beeblebrox]

Material, heal thyself!

[@Avokado34]

The future: 3D printing stuff with self-healing materials taken from astreoid belts.

[@ruddthree8105]

I keep finding new ways to love the time period I'm growing up in.

[@captainslarry1277]

excellent work new guy!

[@kathyaf.365]

What the- I just bought a self healing cutting mat and was wondering about the self healing part. SciShow delivers!

[@kyleluccasen1562]

i love this guy

[@inquisitivebeyblade8598]

That's badass, but terrifying- WE'RE MAKING T-1000'S BABY! WOOH!!!!

[@G33KST4R]

Nice! I just hope this technology greatly reduces waste.

[@petterirantamaki7382]

Good news for a more sustainable and greener future!

[@snekky4456]

1:35 - More like "SULFUR,so good."!

[@evelynscharf7828]

I like this guy. He's a good host.

[@chibbles656]

3:04 What did he say? *Two chains! Yeah*

[@teknolojigezgini203]

i was wondering this topic thanks for video

[@Sharingan1997x]

please make more videos on polymer material sciences!

[@TheRookyMarky]

Eyyyy current ILLINI, glad to see us on SciShow

[@devyendudutta2774]

Is this guy's name Howard? He looks like a Howard

[@devyendudutta2774]

So a french howard?

[@TheMinorsRap]

I can't get over how hard he is trying to act exactly like Hank. it irks me.

[@Astrofiave]

Vern Emcee he's so much different than Hank. Hank is always adding jokes or going about it in light-hearted way. This guy just gives the info straight away. I like either of them for different reasons

[@aetius254]

very intriguing

[@Ceallai]

You know you're an adult when your reaction to "sidewalks that can heal themselves" is "YESSSS OMG GET ON THAT"

[@jonahlongoria]

Food needs this

[@sststr]

Self-sealing fuel tanks have been a thing since at least WW2.

[@brokenacoustic]

I was going to say this stuff sounds much like self fusing silicone tape, been around for ages. Different, but still, not entirely new.

[@dumbname6317]

soooooo, the tire rubber would be like cold welding for rubber?

[@DavidKenny64]

Sounds like something you would want on the skin of your spaceship.

[@dogishappy0]

speaking as someone who lives in Florida, I've had to throw out more tires due to cracks in the sidewall from weather exposure than I had to do for tread ware. If self healing tires with healing agent could cost less than two sets of tires it would be worth it for me.

[@maverickbna]

Materials science is a really cool subject. I took a materials science class in high school, and had a great time. I considered materials science and engineering as a secondary subject of study for my college career, but I couldn't get into the schools that offer it. Go figure. Thanks for the great video!

[@thstroyur]

And zilch on the material (asphalt, I think) that self-heals on tiny capsules full of static bacteria

[@patrickmccurry1563]

Follow up could be about experimental "self-healing" electrical circuits.

[@eurobulk5407]

So is it cold welding? I mean that might cause problems in a tight tyre profile, no?

[@friederichhuepfenstolz4011]

Ending is better than mending!

[@AtomicEy]

it all sounds like good stuff :)

[@AlcuBerry]

I really like this guy. His delivery is somewhere between Hank and Micheal. :)

[@massimookissed1023]

Miguel Alcubierre , Hankael. (Or Mank)

[@AlcuBerry]

Massimo O'Kissed I thought about that too, better still: Micheal Green.

[@abizarthahir3613]

yes, finally something to make boots sole last longer

[@Kio_Kurashi]

The plastic one sounds like it might add to the the problem of trash in the oceans. I would assume that it wouldn't be used on things like Bottles or Containers for food, but that doesn't mean it wouldn't get into the environment and cause damage.

[@MisterLepton]

I'm pretty sure you're not actually breaking the bonds of the rubber when you cut it. You're just pulling the long, stringy molecules away from each other. So, in theory, all you would need is a compound that slowly kept reacting with itself over time so that when the molecules were pulled apart, new bonds would form and connect the two pieces together.

[@DaftBunny]

Some comments; First, these materials do not last 'indefinitely'. The repair does not continue to be perfect unfortunately :) In the case of using healing agent, it will eventually run out. Second, there are many more methods other than ionic bonds and using healing agents to self-heal materials. It is worth mentioning that this is just a very small selection of the cool stuff that is being developed :D Thirdly, rubbers and plastics are all polymers. 'Polymer' is the family name for many, many materials. Just to clarify these things, not to criticize. It's nice to see the field getting some attention! If you have any questions feel free to ask, I research self-healing rubbers.

[@Palamag1]

What I got from this video is that when rubber breaks, a bunch of bro(mides)s get salty and bond together.

[@cutthroatheresy6211]

Stefan "Part-Time" Chin

[@DoorSCARF]

Oh my god this blew my mind

[@soup2634]

Dope! Also, gj new guy.

[@djp1234]

Been hearing about these materials for decades. Let me know when it's available on amazon.

[@chizwhiz5341]

Material science is super-cool :D

[@TemporalOnline]

Close to what happens with non treated metals in space - they bond together because there are no layer of oxide between them.

[@maxximumb]

I love sci show. A four minute video to say scientists have made a new tyre with glue in it.

[@ColtaineCrows]

Well, I try to fix it first before I throw it away, or see if I can salvage any parts that I might need.

[@brynt91]

this makes me happy. i'm tired of my car tire going flat

[@JeremyWS]

That would be kinda neat. I drop my iPhone and the screen breaks, but then after awhile the screen heals itself. I think a lot of iPhone owners would love this. However Android doesn't really need this, as you can drop those things over 600x before the screen breaks for the first time. I think this would be awesome. If it ever becomes widespread, it'll change everything.

[@bigdaduhbouncer]

CREAM always makes itself better.

[@primalchaotix3715]

3:56-3:58 The word condom popped into my head after hearing that XD

[@joannaleiserson9120]

I started noticing all the hand gestures more and more.

[@jacobdial2448]

Dmdnt is my favorite 80s band

[@AymenDZA]

they should make genji out of this material !!

[@ProfessorPolitics]

What's the prospect of making these materials into stuff like roads and/or bridges. Because the savings to our infrastructure (when we, you know, finally get around to addressing it) would be huge!

[@AvatarOfBhaal]

Yay! A new nerd!!!

[@WigantX]

There was this movie in the 80's about a self-healing car named Christine. Things didn't end up well for anyone there...

[@tryhardofdoom7682]

I'm surprised that I have yet to see a troll commmenting: "But will this help me last longer?"

[@TheTeddyIsALiar]

This dude's arms are built like Tom Cruise's character in Tropic Thunder. I feel like he'd punch my face inside out.

[@GTLugo]

Blizzard needs upgrade Genji's suit with self-healing materials.

[@ericvulgate]

the business interests that gave us 'planned obsolescence' won't be jumping to sell us these materials..

[@stax6092]

I will now have a self-healing house.

[@alexchan6303]

Hank, have a Snickers. You're not you when you're hungry.

[@jamesvadamsjr]

this is an underrated comment.

[@billybill4422]

Does this GEEK have to represent every syllable with a hand gesture!!🐒

[@zomfgeclipse]

Hello new speaker. Your voice is quite listenable. Well done

[@bradleybell8417]

Got that buzz on this 4:20 video.

[@davidbuschhorn6539]

My summer tires are rubber-free. They're 100% nitrile.

[@Romulusmap]

Tyres do heat up while driving due to the flexing of the rubber.

[@calixtourgelles3453]

father and son bonding

[@tomatoflight]

WHOO IS THIS WHYYY

[@aronseptianto8142]

just asking,how long will those healing angent last for a normal use(you don't scratch it intentionally)

[@17clon2cwr]

Please create self healing shoes, and phone screens. I would be much happier in life. :)

[@wsxzaq6813]

Now you have to make the DMDNT packets heal themselves

[@prankmypants]

I'm still holding out for humans gaining the ability to regrow lost limbs.

[@kiinain6181]

Genji still needs healing!!!

[@mattholden1469]

This dude reminds me of the guy in the cardboard fort from Benchwarmers

[@davidofchinkov41]

self healing tires? *eurobeat intensifies*
