  • I love stuff like this

  • I hope one day this technology is adapted as plasters/medical tape. My newborn requires an NG tube for feeding and we have to tape it to his cheek, but he is allergic to adhesive and we are now in a battle over managing his poor skin degrading. It makes me happy to think how future families in similar situations could benefit from this concept.

    • Such a good idea. Hope your newborn gets well soon.

    • Specifically, model 2770-1

    • I imagine you tried everything, but just in case, 3M Kind Removal Silicone Tape might help. They are blue, with easy-tear crisscrosses. Good luck!

    • Try Hypoallergenic band aid

    • I recommend looking for hypoallergenic tape if you haven't already, many people who are sensitive to adhesive find it to be a life saver.

  • I remember people telling me gecko tape would NEVER be possible, even the guy inventing this tape says so, but he still persisted and they developed something that comes pretty close to it. This is amazing! Another dream come true

    • Surely using a laser you could in theory create a more robust mould to create the tape with? Also some kind of weird flexible fractal material could wok also. Not saying easy to do but I wouldn't rule it out

    • @Joseph Bolt That would be a wonderful world, sadly that world isn't supported by USA.

    • @Google made me do it Imagine a world where every school teacher has a PhD, holy knowledge cow.

    • @KindaBlackGuy None, we live in the wonderful Belgium where student debt isn't a thing. It's pretty normal here for people to get PhD's and become a high school teacher anyways because we care more about education than capitalism ;)

    • Man that sucks FR I wonder how much student debt she’s fighting off on a HS teachers salary.

  • This is one of the most impressive inventions and best videos I've seen in a long time. Great video, thanks Derek and team

  • Hi Veritasium, For the purpose of accuracy, the gecko in your demonstration @3:14 is a leopard gecko. This is one of the few geckos which uses claws instead of grippy pads and cannot climb on glasslike surfaces. A better model would have been a crested gecko. -my gecko obsessed partner.

  • Definitely the most impressive gecko tape I've seen. Neat stuff

    • I don't know how much better this gecko tape is, but I still think that sticky nanotape is better overall since it's more available than this type.

    • And why don't people see that this is a brilliantly created mechanism by a brilliantly creative creator? It's obviously so well designed!

    • You should check out geck skin. It's also biomimicry but it's based on the relationship between skin and tendons as opposed to skin texture. I honestly don't fully understand it, but it doesn't require microscopic features which should make it easier to produce.

    • Don't tell me you didn't cross your mind to glue one of your colleagues in the lab to a chair :)

    • I am totally against your point of view

  • Wonder if we’ll ever see anything like this applied to tire technology

  • This video mentioned the Van der Waals force to explain how tapes shaped like a gecko's one stick to objects, but you can more simply. It's a friction. So another tips you can know here is that friction is a culmination of Van der Waals force, which is the tiniest interaction that particles can have.

  • The way the short for this video is being used is the best way I’ve ever seen a short being used. Basically a sample of the first part of the video, instead of some 1/30 part short compilation. Would be great if all ID-tvrs did it this way.

  • Wow. I wish I had had a chance to get into this kind of mechanical research. So fascinating

  • Thanks so much to Derek and team for visiting our lab! This was a great video on our gecko-inspired adhesives, and the best explanation yet of Van der Waals forces.

    • Does the skin hold reliably enough to be used to hang paintings, mount TVs or hang Christmas lights?

    • Thanks for sharing. It's very interesting and I hope to see it out being used in the world some day

    • Isn't van der waal that song that's overplayed at every coffee shop?

    • @polerin non-robtics uses like Spiderman suit that helps you climb buildings ?

    • Yes we want you to climb using gecko skin, but you must create whole super hero costume as : Gecko man

  • Great video Derek! I have a question though, if you mentioned earlier that if you invert the Apple over then the sticky pad let's the Apple go. Which means that in order to unstick those pads we need to apply force in any direction except that of just the parallel direction, so how do geckos still stick on roofs?

  • Very interesting that the gecko evolved into having those nano structures. So so fascinating

    • @TheFinnishBaconShroom Agreed

    • @TN If I’m not supposed to be satisfied with ‘it took millions of years’, then why should I be satisfied with ‘it was designed and created’? Hypocrisy much??

    • @TN For all I care, if there's a god or gods, god(s) could have planned the evolution, which then would mean you're diminishing gods work, which goes against everything every religion says.

    • @TN Either is a possibility, I'm all up for aliens doing genetic engineering. :P

    • The gecko obviously didn't evolve, it was designed and created. Ask yourself how things evolved, and don't be satisfied with the 'oh it took millions of years' answer.

  • 5:01 maybe in future its possible, when they able to extract the blueprint (3d file) out of gecko DNA and print it with organic 3d printer just to make that hand organs at any given size... booom magic

    • Great fan,🌹🎖💫 Wish you a happy new year let make your new year fun 😊 You are among my selected Winners Use the Above name on (Telegram) to Acknowledge your prize.👆👆👆👆👆.......🎉🎉🎉🎉

  • Great video Derek! I have a question though, when performing all those heavy tasks like pulling the car, how was the material able to handle those force because the material itself is made up of silicone right? Which I know is tensile, but not that much! So how did it withstand those forces?

    • Congratulations great fan 🎖️🎖️ You are among my shortlisted winners 🎁🎁 🎁 use the above name to acknowledge your prize on Nicegram..

  • I'm blown away by how Vertiasium finds such fascinating topics all the time. I love so much learning fun things like this!

    • yeah but his clickbaits are annoying

    • :)

    • Literally just read a science journal once a month.

    • I bet the requests he gets weekly are in the hundreds

    • Vertiasium.... you mean veritasium?

  • It would be cool to make gloves out of this so that you could pick up anything. But I also am curious weather or not this material could attach to something slightly slimy, and if not the proper way, then what about the reverse way. Would the ridges hold on to something slimy or rough better than turning it the other way?

  • Damn. You are the type of channel that inspires me to research nature ( Im studying biotechnology, due to the wonders of nature, which I often learn from these type of channels )

  • Man. This seems so cool and awesome. I can think of actual practical applications this might have and in about 5 years from now, this might be in our lives in ways unimaginable. Veritasium is one of my favourite channel on YT. Loved the video absolutely!

  • Wow i remember when i was younger, my family didn't have cable so i was stuck watching local TV. One of my favorite shows was on PBS kids called Wild Kratts. These 2 guys taught you all about animals but one of my favorites was the Gecko. The guys in this show had Gecko-inspired suits which i always wanted to be real. This is really making my childhood dreams come true

  • I remember years ago as a young teen reading in a science magazine that someone was developing this. It's so cool to actually learn about the progress

    • @ArrKayCee I remembered similar thing about 3D printer. Now we got a youtube channel called Unnecesary Inventions

    • @kailoveskitties aerogel is so expensive, it really is a shame

    • When I was between 8-10ish, I got a children’s science magazine and I clearly remember it talking about how someday there would be self-healing plastic, and how we’d be able to print physical objects, and how a material was being developed that could protect a rose from a blowtorch with just a thin layer. Now, about 20 years later, if I bought a piece of aerogel (which is amazingly something one can do for about $50), I would have all three of those inventions in my home.

    • Same here. I watched a feature on this subject and always kept an eye out for gecko related subjects. It's great to see their achievements now.

    • Samee! I remember being so excited for when it would be a real thing, and here we are now! 😂

  • if a human pulled the whales weight the tape would scale up from tiny robot size to human size too right? So if we just wanted to climb with the tape and carry our own weight instead of a whole whale, the scale of the lamella could be sized up by a lot, right? the biggest problem would be that our hands and feet are too small of a contact area in comparison to what the little robot used. we'd need some sort of exoskeleton to size up our feet and hands.

  • I really hope this gets improved upon cause this would be so useful for many different things. (Like not needing a ladder maybe) But also I can't be the only one who has dreamed of climbing like a gecko for fun (or spiderman/xenomorph) xD

  • Incredibly cool, I love when technology directly takes inspiration from the animal kingdom

  • As always, nature is the best engineer, truly impressive.

  • Idea that a living organism, and somewhat large at that, uses van der waal forces to move is mindblowing

    • if anyone wants to know its exactly londons dispersion force that makes geckos stick to surfaces

    • @Legendendear that's the magic of millions of years of brute forcing a solution to carving out an ecological niche.

    • Never underestimate the consequences of the magnitude of Avogadro's Number.

    • @Quinson then what is it

    • @pyropulse by no means is the dipolar interpretation of the atom basic stuff. it only becomes dipolar because of the influence from another atom. two atoms in close proximity affect each other’s charge distribution. the negative charges of the electrons are outside of the protons and so will move to cause electrostatic attraction. that is van der waals.

  • Thank you Derek for always teaching us new things. I love your work! It helps me so much!

  • I've always thought that wander walls forces are very weak. I knew that it acted between the atomic sheets of graphite and holds the entire thing together but after seeing this video I think completely different about this amazing force which could handle sheer strength. Imagine how much strong it would be if we were to replicate it exactly like that of a gecko has!

    • Congratulations great fan 🎖️🎖️ You are among my shortlisted winners 🎁🎁 🎁 use the above name to acknowledge your prize on Nicegram..

  • That's revolutionary, also makes me think why didn't they think of it before, awesome work no doubt, very impressive.

  • this is absolutely amazing! a professor of inorganic chemistry i had in college used geckos to explain van de waals forces. He went on saying that geckos used the induced dipoles to attach themselves to walls, but weak as those forces are, they were not enough to make a new substance, or else we would end up with some "wall geckoate" (free translation) everytime a gecko climbs something

  • Hello Derek, I have an idea for a video. In chemistry, I learned that in redox reactions, electrons transfer, but it was never quite explained how or why exactly they do it. I would love a video about this process, which I found out is explained using quantum mechanics. That way, I might finally understand how the electrochemical potential table forms and why different organisms are an-/aerobic on a deeper level. If you (not Derek) read this and also wonder how this works, I would appreciate if you could give this comment a push so that Derek sees it. Thanks, keep up the good work, and greetings from Switzerland. Alejandro

  • Could this be used on car tyres to prevent lateral sliding?

  • This is stuff i would think of as a child and now all these years later science has brought us o the point where EVERYTHING, all the weird thoughts of how things work and how we could use that to our advantage has been played out in front me on a computer screen . its mind boggling

  • I would try this gecko adhesive out myself. Really hope this will be widely available in the future

  • I remember learning about the science of gecko feet when watching Wild Kratts in kindergarten. So surprised and happy to see it pop up on Dr.Muller's channel again!

  • My grandfather has a PhD in zoology and biology. I'll never forget the day when he showed me a scientific journal entry with a picture of this and how fascinating they were to him. He is an ichthyologist, so it wasn't his area of expertise; however, there were always some facts he could add to a situation or story, and how he described that truly humbled me at the time and still does. I credit my grandfather for my curiosity and thank creators like you for making me extremely proud of him, highlighting fascinating things in our universe, and invigorating those who are hungry for more knowledge. Thank you.

    • @ConservativeRiot Love your passion nice man

    • @ConservativeRiot I used to be a devout Christian as well. I used to study the Bible quite a lot, and I still go to church every week (not by free will). My perspective changed and I no longer saw the religion the same way I did as a child. I'm now much happier and found a new way to appreciate life, so no need to convince me to go back. Thanks for being respectful, have a great day, just be mindful of where to talk about religion so that people are more willing to listen.

    • @Amritendu Rana oh yeah

    • @Alexandrite I used to be an enemy of God as well. I hope he opens your eyes like He did mine. At least a couple people liked my comment. I can't help but to see God's wonderful design anymore and there's nothing wrong with pointing it out. Thank you, have a wonderful day.

    • @ConservativeRiot nope lol

  • Definitely want a gecko suit now. On another thought, could tires be made of this stuff? I'd be interested in seeing how long the tread would last, or if pavement is just too rough for it to work at all.

    • No, because tires need to be able to wear down like an eraser, and those razor sharp treats would wear down immediately at high speeds. Not to mention you need to grip non-smooth, dirty, wet, and snowy surfaces... it would be interesting to see how they perform on ice though.

  • Very cool tech. It's hard to improve upon evolution, regardless of how advanced our technology has become. I'd love to see the day when these fine structures (spatula) can be accurately replicated.

  • I literally had this idea like, organically the other day while getting baked except it was a tarantula pad. Like imagine if you had literal gloves covered in those micro hairs as well as a, like, an offset roofers platform for each foot. You could def climb a building

  • Great video! Van der Walls Force is incredible but be Warned once you want to calculate the energy in the interaction from an appropriate Hamiltonian you will see what a nightmare it can be but anyways still very cool stuff

  • I _LOVE_ that you've published this. My nine year old has started a new theme at school this month, called biomimicry... I'm going to show this video to her; she'll love it.

    • @6th Wilbury Yeah, I think it depends on the parents, to be honest. I mean, if you are always talking about things you're fascinated with, kids will naturally be attracted to those things as well. The "Did you know" kind of facts are super popular with kids and even kids TV shows dance around this topic all the time. We give it a fancy name as an adult, but the idea that inventors design things inspired from the designs of nature isn't a difficult concept to grasp. Did you know that the kingfisher's beak inspired the Shinkansen? Did you know that sonar in submarines was an idea that we got from the design of sonar in bats or dolphins? Did you know that those Airplane winglets are inspired by the upturned wings of an Eagle? Did you know that a spider's silk scaled up to 1cm could catch a jumbo jet in flight? Kids books are FILLED with little factoids like that and they have units in school that actually teach it. Kids are naturally curious and learn about the world around them literally and so biomimetics is a useful tool OFTEN used by many science teachers... because of the way that children rely on literal interpretations of the world around them to learn as opposed to how adults are able to more easily digest abstract concepts. I just don't think it's all that uncommon.

    • @TheNewGreenIsBlue I don't doubt they exhibit it, I'm talking about a nine-year-old being interested in it as a concept.

    • @AtBZ 🧤 Because if that was my child, I'd be proud of my child. And want to make them happier. And share the happiness with others, because the world is a slightly better place having known.

    • @6th Wilbury 9-year olds are very often interested in biomimicry. How could you not be? It's adults that take the amazing designs around us for granted... maybe because they were taught to just blow it off as a product of random accidents.

    • @AtBZ 🧤 No kidding. My kids had a unit on biomimicry as well. It's pretty much a standard thing that they teach in elementary school these days. I have helped BOTH my daughters still in regular old public elementary schools do projects on the amazing designs of the world around us. Everything from the remarkable strength to weight ratio of the Toucan's beak, to the kingfisher's beak's inspiration for Japan's bullet trains. Intelligent humans design things around them all the time... and although generally far inferior to the the natural designs around us, still impressive and starts with curiosity.

  • I think it’s amazing how much utility this can have there commercial scale robots to pull stuff but also can be a consumer product like a product to hand stuff

  • 11:11 would've been cool to take them off *one by one* to test *when* the maximum is reached and how that would express itself.

  • The first min i had a guess for an image of how this works exactly in my brain. I was happy watching the video because i was literally spot on 100% 😂 maybe i am a gecko after all 😅

  • This is one of the most impressive and incredible things that I’ve seen in a long time.

  • This exact effect was the reason I studied materials science in my masters. It's just incredible how far we have come, that we are able to use such effects on materials that *.*

    • @Gladius No, the material isn't cheap to produce, you would pay an extra couple hundred/thousand depending on the size.

    • @Sean Kane as they say in the video, what they can do is a very raw bad approx of what a gecko can. I would say they do not more than a mere 5-10% (i am being optimistic) and so, the possibilities are HUGE. We need to learn how to build something purely from a DNA.. like a cell does. Crispr is great to modify DNA, but to have a sheet of "gecko foot" made from the Gecko DNA (and then even improving it!) is pure science fiction nowadays. Having this capability will open the "God door" with unimaginable possibilities. We are so so far from that (50 years?)

    • Very cool, what materials are you working on now?

    • @Enorazza Right? I'm so curious how much better is the gecko than the artificial version, considering we seem to be able to fill the same surface area. Is it something like 80% as good, 95% as good? What if it were like half as good as the gecko? Crazy to think of the possibilities were that the case and we just need to iterate on the processes

    • @Gladius I'd imagine so if the vinyl sheets mentioned use this force, but I have noticed some that are noticeably sticky one one side so perhaps some indeed use a thin adhesive in some fashion

  • Damm this video made me realize how much power we ”waste” like if things were calibrated optimally in the physical realm it doesnt seem to be hard to do anythibg really. Lift, move, whatever we’re talking about. Like 4 pieces of tape can pull a car all because the contact area in which the energy transfers is finally ”bigger”. Mindboggling

  • Thank you for showing this tech, i always wanted to know insects, geckos climb and build projects like that, I researched but everyone talked about only Suction cu which is not always helpful.. This is really informative and useful!

  • What would the impact of say DUST have on the grip properties? Lizards can move in areas with dust... I wish you looked in to this too...

  • I *absolutely love* that the YT short takes me right into the video and I don't have to rewatch the part I already watched.

  • I remember in one of my nanotechnology courses at university around 2012 one of the physics lecturers told us about people investigating this sort of technology. Amazing to see it in action.

    • @RICO PARADISE ☮️☯️

    • 2012 i was in 7th grade, interested in geckos and found the same news. Glad, that they finally understood geckos more and made gecko tape^^

    • ✝️ LORD JESUS DIED & ROSE AGAIN TO PAY THE DEBT OF UR SIN! ✅By Faith in the sacrifice God has made are we saved from the penalty of sin! 🔵Turn from your sin that leads to death & accept His Gift that leads to eternal Life! 💜We are all sinners that need God. No one can say they are perfect to be able to pay their debt of sin. This is why only God could pay the penalty for us, that is merciful Love!

    • I've seen research like this for years. I think there was even a Bill Nye episode iirc. This is probably the furthest it's come since.

    • Kinda shows how University can have a place, but it ends up being a fraction of our lives in many cases. Uni didn't really say we'd move on and never need them, for reasons.

  • This seems like it would work on a tracked device for climbing smooth walls.

  • probably the best video I've ever watched, absolutely loved it.

  • That's so cool. It's amazing how something can be so simple but so complicated to replicate. And to be honest I still don't understand the part where it can pull a car... Unrelated, but when I saw the brilliant ad at the end, I realized something obvious: Artificial Intelligence is gonna be a mandatory subject in schools eventually. That's mindblowing to me. I've always postponed learning about neural networks and AI even though I was interested in it. Now, I _know_ I will end up learning how it works eventually, wether I like it or not lol

  • Vertasium never disappoints us with his content!

  • Yes, Derek. I do want to see you climb something using gecko socks. One question, regardless of how strong the grip is, the material it's made of has to be strong enough to with stand the weight of what it's pulling doesn't it? So what are those strips made of that can withstand the weight of a car between just 4 of them?

    • @Alex Larson Oh of course, great explanation. Thank you

    • The object you climb would also need to support your weight.

    • You could do the same thing with regular duct tape, since there's not a lot of force involved, but the op provides a valid point. If one were to use this for lifting any meaningful amount of weight, the material will need to be far stronger.

    • You mean the ones they use to pull the car with the little robots? It isn't withstanding the car's weight, just the pulling force

    • Keep in mind the idea that the tape is “pulling” the weight of car is a little misleading. It’s not like the tape needs to hold the weight of a 3000lb sedan. All you need to do to pull a car on flat ground is to overcome the rolling resistance of the car while it is in neutral. For a 3000lbs sedan that might be something like 50-100lbs. This is an amount of force humans can easily provide hence why you’ll see people pushing their car when stuck or out of gas.

  • wow amazing, I love geckoes, they had to bring themselves up with no parental guidance, maybe that is why they can climb and walk up walls, upside down on ceilings, nobody told them they couldn't....when I say parental guidance, I mean material of course, geckoes show me that our Creator is a genius....the King of Science, GOD

  • Hey, can you make a video explaining how astronomers calculate the movement of a celestial body. Especially the orbits, velocity, the position at certain time. I am very interested in this. 😄 🪐

  • Amazing! Extremely interesting research done there! For a long time now I wanted to test that kind of stuff for attaching prosthetics to limbs. And yes, please do climb a building with it!

  • Heard about this more than a decade ago. Was wondering what happened to the technology.

  • @5:01 "we cannot make what the geck has" loved the level of awe he has for the geckos architecture

    • Well... you could farm geckos for their skin...

    • @Maritata Chan The Bible is an extremely rigorously tested historical document... Jesus really existed and there is no valid reason to doubt the authenticity of the New Testament (or Old Testament for that matter). Other than your existing biases that is. Open your eyes and soften your heart. If the Bible is even 10% right about Jesus then it's actually worth investigating. I have daily peace and joy because I know how everything will end, and it will be with Christ as king.

    • @Blobbyo25 You are seriously citing the bible as a reliable source? Please, what a joke 💀

    • @Blobbyo25 "in the beginning was the word, and the word was with the god, and the word was god" who said that in the verse of the bible?

    • @Blobbyo25 If god says "Be universe just be it" is that means the universw is God?

  • The winch experiment alone means that SnR teams will have a great tool to save lives.

  • When I first played Call of Duty: Black Ops II, I thought the Nano Gloves that were use to stick to the sides of cliffs were cool, but that surely they couldn't exist anywhere near as early as 2025. I now think (and hope) they may be possible in the somewhat near future lol

  • Good ol’ Van der Waals forces. I actually shared an SEM once with a grad student who was studying gecko feet for a similar research project. Super cool!

  • that stuff is amazing. great combination of surface physics chemistry and mechanics all inspired by nature. Would be very interesting to see if we couldn't 'grow' something similar to the tiny fibrils the gecko's feet use.

    • I agree. This could be someone's PhD thesis - create a method to do that. It will probably be a combination of chemistry, physics and engineering.

  • This is so ground breaking if you ask me, there are many practical application. I wonder the tremendous progress we'll have if we can replicate the interesting parts of nature. Finally, a Spidey suit, next one should be Iron man's

  • What a brilliant invention take rom nature. Thanks for the content

  • It would be interesting to see if it holds almost as well in vacuum. It might be that under athmospheric conditions the air between the pad an the surface is pushed out almost completely and that the air pressure on the outside pushes the pad to the surface.

    • Somebody made a video once where they dropped a gauge block on another gauge block in a vacuum. They wanted to see if simply "pushing out" the air between the blocks was all that was needed to make them stick together. Their conclusion: The blocks were not sticking. Eliminating the air did absolutely nothing. Similarly it doesn't take much effort to show the reverse: Putting two stuck-together gauge blocks in a vacuum doesn't unstick them either.

  • Two right angles exist on a perfecly level horizon, obviously parallel, at what point do they stop being so? Can you construct an experiment so we can visualize the results?

  • One question I came away with is: are the Gecko toes directional like the artificial material, or is their structure so fine that they don't need to flatten in order to stick?

    • @N C If you don't mind me saying, that is an entirely unsafe conclusion. I can understand how you might categorise individuals as being creative or precise, without realising that some are both. One never quite knows who is contributing to these threads.. but thanks for your comment.

    • @andrew cobb If you need to focus that hard on a missing apostrophe, it's safe to say 'combing for arbitrary missed characters in comment sections' might be your skill set, whereas mine is more 'having thoughts and knowing things.'

    • @N C Top tip: use a spellchecker before you declaim :)

    • @N C we're not the experts in this matter so our deal is to assume. You can not make conclusions from the photo either. So you are assuming things too. Am I wrong?

    • ​@Mikhail Efremov Not good to just make stuff up. It is visually apparent from the microscope photo that they are NOT omnidirectional.

  • I remember back when I was a kid, scientists still didn't quite understand geckos, much less have tech to mimick the grippy-ness. Very cool!

  • Had no idea how fascinating Geckos were aha, thanks for more science lessons Derek!

  • Such intricacy on a micro level is mind blowing, and amazingly it is all by design. The amount of times I’ve heard scientists believe in God because of these factors is wonderful. God’s power and attention to detail is so beyond human understanding, praise The Lord!

  • 6:40 Ha! YES! I was able to guess partly how it was doing it from the start of the video! I know I was probably just lucky, but now I feel super smart about molecular physics!

  • The fact that it only took six of those tiny robots to pull a car is kind of insane.

    • @notahotshot Given I actively factored communication out of that statement, I'm definitely not confusing the two. Only the first point I made was about ease of communication. My second statement - the one you quoted - was not about communication. Plus precision doesn't come from standardization; ease of communication does, which you supposedly think has nothing to do with precision. On top of which, you're mis-attributing the word nomenclature. What you call the measurements is irrelevant to how the system works or which values are used for scaling. The odd nomenclature doesn't reinforce or dissolve either of our points, so I don't see why you feel the need to remind me of it. As for the creation of the metric system - people make new systems because it's easier to get people to bandwagon onto a new thing than it is to change how they use an old thing. I'm aware that it had nothing to do with precision at the time, which is why I didn't make that argument. On the other hand, that doesn't mean that metric - as we know it today - is less precise. The reason Imperial is naturally less precise is because every unit has it's an individual scalar value. Every time you have to translate between those scales, there's a risk of a translation error, which grows exponentially every time you switch unit. And that's not a communication thing - that's a maths thing. The same risk holds true for digital computation. You're clearly stuck on the idea of minutiae aspect of precision rather than accuracy, and if you want to say that the thou is more precise than a millimetre, then I'd agree (before reminding you of nanometres and all the other units smaller than 0.1 thou), but the Imperial system *as a whole* is imprecise when compared to the metric system *as a whole.*

    • @Samurai Pipotchi "That's naturally more precise." No, it's not. You're confusing ease of communication with precision within the system. Precision comes from standardization, and from how finely divided your measurements are, not how you name them. I can divide imperial measurements just as finely as you can divide metric. The issue with imperial was that the length of the measurements were not standardized. Rather than getting everyone to agree on how to define the length of a yard, a new measurement, the meter, was devised, and the base measurement defined. Then the measurement was later redefined multiple times. Because of the natural inaccuracy of the definitions used. The world could have just as easily standardized on imperial, if an agreement on how to define the measurements could have been reached. Note that I did say, in my previous comment, that the nomenclature could have been better.

    • @notahotshot Because it's true for a lot of us. I'm in the UK. Our tools use mm adjustments - just like almost every non-english speaking country. Trying to describe which metric adjustment you need while using imperial terms is going to lead to a natural imprecision. There's also the benefit that metric technically only has one unit of measurement and the terminology just specifies where we're putting the decimal place. That's naturally a more precise system than one that changes it's scaling based on which unit you're using.

    • @Samurai Pipotchi "Metric is necessary when it comes to precision measurements..." Why do people make this claim? I can divide imperial measurements in as fine an increment as needed to get as accurate a measurement as required. The nomenclature could have been better for the divisions, but the nomenclature has no effect on the level of accuracy possible.

    • @The Creatist 😂 oops, I'm caught.

  • It's crazy how much nature inspires modern technology

  • truly fascinating what is able to be created with technology. I wonder how this technology will progress and be used in the future?

  • This is an amazingly interesting video, nice work as usaual.

  • This what I really need, been wondering how the gecko’s feet works, cheers

  • fun fact, some geckos held on so strong during hurricanes that their arms elongated due to the high wind speeds. This actually happened recently.

    • Skill issue

    • @Coldby probably. Imagine looking like the gecko version of bigfoot.

    • That must have hurt

    • They need to train harder.

    • "Never skip finger day, bruh." -some geckos

  • Love how this shows how smart nature is. Fascinating video and product.

  • Honestly, I don't know why any companies are doing this 🤔Seems like such a necessary and awesome product!

  • theres soooo many applications for this... I love seeing innovation... maybe this could help ejection mechanisms for decouplers and such

  • I think that it's amazing that God created something so fine-tuned and beautiful. Like He's so creative and fun! He could've used the same principles as suction or hairs but He decided to create something new. Even though we couldn't see it for the longest time it's always been there and it's just absolute ingenuity.

  • I'm surprised how creative the team got when manufacturing the material/characterizing the force. I thought it would be closer to the methods of silicon etching and nanostructure growing

    • @hazonku I suspect a metal mold will not release the silicone without micro-tears of the tiny ridges which will ruin the gripping properties. And at the tiny scale they are working in prohibits using a mold release agent which would take too much space. I think the main draw of using wax is that it will easily release and separate from the silicone once cured

    • it's more like nanoimprint lithography, which is developped later than commonly used photolithography

    • lol I was amazed how jank it is. This is how I would do it in my basement

    • Right? This is actually FAR closer to a process that can be easily transformed into a mass production process.

    • And not a carbon nanotube to be found.

  • I remember hearing about this 10 years ago, it's so cool

  • Obsessed mountain climber will thank you for this invention Also did anyone attempt gecko skin wheels for vertical navigation?

  • That would be a great help in the auto collision industry. They use glue to pull out dents from car's. This would be a better and much cleaner option.

  • No wonder a mere "geek science" channel has 13.3M subscribers. The wonders are a scientist/s were smart enough to figure this out as well as realise real world applications for it. The other is that nature never stops teaching. Endlessly fascinating. Thank you.

  • Years on after leaving school and I am continuously impressed by the quality of the content you provide for free that far exceeds most institutions. It’s just amazing how simply you explain concepts in a quarter of an hour.

    • @King Oreo booger🤑🤑🤑🤑

    • He has sponsers Hopefully they arent all bad people

    • @dreadlistwhat?

    • That's why the school is

    • @Wesley Schroeder angry birds.

  • 10:22 - I can see the bulky item thing being useful for humans too, could have gloves covered in the stuff similarly to the robotic gripper

  • As a novice climber, having gloves with this surface would be really helpful

  • Thanks Derek, I finally know what Van-der-Waals force truly is.

  • I just discovered this channel and I'M ABSOLUTELY LOVING THESE VIDEOS!!!

  • When I was in School, about 15 years ago, we had this book "Geko's Foot" in our library, it was full of how amazing and fascinating the Geko's foot was! The ideas discussed in the book are now a reality! Science does make progress!

    • @Robert Pruitt I mean it is easier to sit your ass at home and demand progress when you are not the one at work. We tend to see scientific and technological advancement as something that is bound to happen and that we are 100% entitled to. Although it's like it's almost impossible to slow its pace down now 'cause many hands are on deck, these things have always been done by people like ourselves and they actually take time. It's just that successful ones are easy to spot than thousand of the unknown, failed procedures leading to successful ones.

    • @Earthling six billion something and one Things have always taken quite a while. We just didn't hear about the research until it was getting close to market. We might be more advanced than in decades past, but we're also doing more complicated things. It took NASA 20 years to get JWST done. But they had to invent half a dozen new technologies and advance them enough to be usable in space. It took 11 years to make the Blu-ray. Even though it's just a DVD with a different color laser and new programming. It was 80 years after the invention of the fridge before you could buy one in a store.

    • @Earthling six billion something and one it makes nature even more amazing

    • It's kinda sad that this is the progress after decades.

  • It would be useful to know how long this stuff lasts. I can imagine the surfaces getting clogged with dust particles thus rendering it useless. What about wear and tear, cleaning and maintenance? I guess this was omitted because it does not last usefully long enough to be of any practical use. Still, a worthy video to watch till the end.

    • So the cool thing about the gecko tape is that it is actually self-cleaning. Of course at this stage not to the point of real gecko skin (which actually becomes more effective the more it's used), but it still self cleans. So dust would not be much of a problem. As for wear and tear, I believe it is about as strong as typical tape. The main caveat is simply the fact that it works mainly on smooth surfaces only.

    • Thanks for watching and leaving a comment👍. Telegram the above username, got a package for you 📦🎉...

  • If I hadn't seen a gecko walking up a smooth wall in real life, I'd find it hard to believe it was possible.

  • Since nobody seems to mention it, Thought Emporium and Applied Science also made great videos on gecko tape, and methods of making it yourself

  • also i love how after watching the short, he gave us the exact moment the short continues from

  • I love how the technique they use for manufacturing this stuff is dead simple on a small scale. Their machine is quite large for the precission, so that's definitely where it gets to an impressive level of engineering, but if you wanted a few millimeters of the stuff, sub-micron precission is super easy to obtain at that level with enough gearing! This gives a lot of hope for the availability of this stuff. I'm sure people will also revolutionize the way it's manufactured to increase the effectiveness, but for this method; basically dead easy and awesome!

    • I want the gripper with the sg90 servo they showed to badly, it seems perfect for picking up cards.
