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.
are there a limit to how much you can use each piece of gecko adhesive? do the small structures degrade overtime so its not as sticky anymore?
Great work you're doing. Nature is so inspiring and we have so much to learn. Question: did you do tests, how your product works/doesn't work on anti-stick (Lotus inspired) materials? Keep up the good work :)
Would it be possible to cover a pipe with the material so that it could be used instead of tire profile. I think it would create way more friction/traction than any slick tire would in good conditions. The pipe would just have to be long enough to have enough contact points… please try and tell me how it went, would be super cool
@White Rabbit when we are asleep we are still conscious. Many people are ignorant on the aspect of what consciousness really is but in the reality we are always awake. It really shows that when we are awake we still don’t know anything given our ego of perception.
I assume it's not currently available as a commercial product, but I might have a non-robotics use for it.. is there a way to get some to experiment? This is just amazing.
Definitely the most impressive gecko tape I've seen. Neat stuff
It's definitely the most impressive gecko tape I've seen too, which is not saying much, since this is the *only* gecko tape I've seen...
Now we just need you to show us how to make it for the price of the change between the couch cushions and an expired Arby's coupon
Yeah top 5
That's the second most impressive gecko tape I've ever seen.
I guess you're going to make some soon?
make sure the wax is almost perfectly flat before cutting the grooves... which should definitely be done by a machine 🤔
if you're able to get those ridges longer, it should be able to stick to rougher surfaces, since they can comply a lot better.
I remember watching a seminar on this topic during my UCSB freshman chemical engineering orientation tour in 2009. Crazy to see the early research I learned about coming to fruition 14 years later.
I really thought those little ridges would be going the other direction, and gripping into whatever they were holding! But this is even more interesting. Looking forward to where this tech could lead in a few years/decades!

Q
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
One of the coolest parts of science is revisiting a topic a few years later and realizing they found the answer they were looking for and from that, 6 new questions arose lol.
What seems to be the first paper written about this was written in 2012.
Me too.
That is indeed very cool lol
Ya, I’m pretty sure 15-20 years ago it was on discovery on that daily science show (I forget it’s name).

I had a school project about biophysics and me and my group chose to talk about the geckos' adhesion, the van der waals forces are only one part of the very complex mechanism these animals use to climb! It's crazy how seemingly simple things in nature can be so complex and how we can learn from these things to build cool stuff. Great video :)
I'm curious what the other parts are?
I keep picturing Tom Cruise climbing the Burj Khalifa
Idea that a living organism, and somewhat large at that, uses van der waal forces to move is mindblowing

Hi
So cool to learn how this stuff is actually made! I've been hearing about the gecko tech for years and all it can do, this is truly awesome.
I'm blown away by how Vertiasium finds such fascinating topics all the time. I love so much learning fun things like this!
I see what you did, it's Bradtastic.
He find topics you only think about when your high lmfao. Dude is great and makes everything interesting.
He's basically Vsauce, with less weirdness and more travelling. I am always excited when new video comes out.
people contact him
This tech has been around for some time, perhaps not as matured as it is now. I remember a buzz during the time one of the MI movies came out where Tom Cruise uses an advanced(albeit fictional) version of this to climb the Burj Khalifa.
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.
I hope to be a marine biologist and have been going to the aquarium lately and seeing their feet and have been fascinated as well as your grandfather, the detail is beautiful
It's all thanks to God and His design.

@@someasiandude4797 🔥🔥🔥That burnt me good
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.
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.
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.

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^^
@@ricoparadiso ☮️☯️
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.
I’m so sorry to hear that my friend, I can’t imagine how it is for you guys. May All the Best be with you.
This technology has lots of applications in manufacturing industry and biomedtech
That is so sad. Is there no hypoallogenic adhesive that could help?
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.
Try Hypoallergenic band aid
Much support for this amazing channel. Thanks for what you reveal
YES! Thank you for this! I’ve been watching for someone to talk about van der waals force! I saw a study from MIT where students actually held up a dictionary with a 1cm^2 square of carbon nanotubes. Super cool tech. Didn’t realized someone had worked van der waals into a tape.

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 *.*
And how much yet we have still to learn. Look on how far from an actual gecko we still are
@@Josh_728 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
@@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
Very cool, what materials are you working on now?
@@spkane86 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?)
We talked about this principle in Nanotechnology class, but it's super cool to see it applied to an actual usecase here.
Thank you so much for the video! 👍 Really enjoyed the content and footage! Enjoyed it))
The fact that it only took six of those tiny robots to pull a car is kind of insane.
What are you talking about? It was four pieces of gecko tape that supported the winch that pulled the car
@@truffle_pig did you watch the video? There were two car pulling tests…
I will add without prior knowledge!
It's less than 100lbs it's exerting. Using a car like this is highly deceptive. It's still very cool stuff. But the demonstration pull is not what it seems. It's like when Toyota shows them pulling a space shuttle with a tundra. It only needed like 500 foot pounds of force to get it moving
@@MajorMokoto Its not meant to be pulling weight , its real use case is in robotic arms to handle delicate items where weight is not an issue and can not use conventional robotic arms because pressure exerted by conventional arms will damage the delicate items
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
Who… who said that to you.
@@fvictor77 My high school biology teacher. She pointed out, like the guy in the video, that their suction ability cannot be recreated in a lab. Only something that mimics it.
Well that’s a kinda dumb thing to say especially as a science teacher they were also saying we would never go to the moon, fly, or breathe underwater. I guess that’s why he was a high school teacher and not a professor
@@fvictor77 My teacher was a woman and she has a PhD in Biology and Physics. She's definitely smarter than you because, if you read this correctly, you'd understand her point is exactly the same as the professor in the video, and you also would have noticed I referred to her as a woman, not a man.
What a way to make a fool of yourself for everyone who can read this.
@@DarkAngelEU oh she’s a woman. My bad not tryna trigger y’all. But why was she a high school teacher… spend all that on a PHD that obviously means she’s not that great. not claiming to be smarter just that a real scientist would ever call something like that impossible.

Incredible. This has been one of the most fascinating videos I've seen in a long time. Imagine all the things we can do with that gecko tape! I wonder when we'll be able to buy it, I'd love to do some experimenting.

I used to have a Crested Gecko - I loved watching him climb. They curl their toes upward to release their grip, and lay them flat to support their weight. It was fascinating to watch.
Your video has answered my questions. Thank you very much for sharing this method that works for all platforms.
It is incredibly fascinating that nature somehow figures all this out and utilizes it perfectly
All those branches in the microscope shot of the gecko pads are very similar to how nature figures things out.
In the case of nature, most of the branches don't work, but a few do, resulting in evolution and natural selection. (Multiple sources say about 99% of species go extinct.)
A "working" branch doesn't mean the _best_ selection, it just means the one that got to make babies and pass its DNA forward, making at least one more branch.
Geckos are a very weird and very cool group of branches.
Makes sense to me. Evolution had quite a long time patch the bugs
A few problems with the theory of evolution.
1. Gaps in the Fossil Record: The fossil record provides valuable evidence for the history of life on Earth. However, there are gaps in the fossil record where transitional forms between different species or major groups are missing. This has led to questions and debates about the completeness of the fossil record and the extent of transitional fossils.
2. Origin of Complex Structures: The origin of complex structures and organs in organisms, such as the eye or the bacterial flagellum, has been a topic of discussion. Critics argue that the step-by-step evolution of such complex structures through natural selection and gradual modifications may pose challenges.
3. Irreducible Complexity: The concept of irreducible complexity, proposed by biochemist Michael Behe, suggests that certain biological systems are so intricately designed that their components are interdependent, making it unlikely for them to have evolved in a stepwise manner. However, this argument has been challenged by evolutionary biologists who argue that complex structures can evolve through incremental changes, with intermediate stages serving different functions.
4. Origin of Life: The theory of evolution focuses on the diversity and adaptation of life forms once life has originated. The question of how life originated from non-living matter, known as abiogenesis, is a separate field of study. While there are various hypotheses and ongoing research in this area, the exact mechanisms of abiogenesis are still not fully understood.
5. Genetic and Epigenetic Factors: Advances in genetics and epigenetics have provided new insights into the complexity of gene regulation and hereditary mechanisms. Some argue that these factors challenge certain aspects of traditional evolutionary theory, raising questions about the role of non-genetic inheritance, epigenetic modifications, and the interplay between genes and the environment in evolution.
@@dan9521not really. Want to email and discuss this further? You've got some misconceptions
Yeah its nature ofcourse, surely gaslighting yourself into thinking that something this precise is somehow has been created rather than asking yourself that someone with a higher power has to be the creator is mind blowing to me.
This is one of the most impressive and incredible things that I’ve seen in a long time.
hehe nice
Imagine if we used this concept, then applied it to every day walking shoes/ slip resistant boots or foot wear in general. Cool concept
I had my equivalent of a Disney moment in my garden a few weeks ago when a gecko landed on the back of my hand. Having the real thing walk across my skin was remarkable. I swear that I could feel the pads of its feet moulding to the profile of my skin and this video kind of confirms that experience. (Beautiful little shimmering speckled beasty!) I let it down gently onto a tussock grass and it went on its way. Biomimetics has much to teach us.
A gecko falling on my hand is my worst nightmare since I have Batrachophobia.

Back in march 2015 I happened to walk into Mark Cutkosky's lab and talked to him. I saw some students playing with a heap of plastic geckos next to a wall panel. Now I know what he was up to then.
sure
This is fascinating. I love this channel so much.
Do note, however, that the hairs on a spider's legs also use Van der Waals forces to adhere to surfaces, so it's a different implementation of the same principle.
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.

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.
@@lordgarion514 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.

Well, evolution just had a very early start compared to human designs. That’s really its single advantage. We can do better and we already have been doing better for centuries (for example, wheel-based tech, electromagnetic tech, in general many obscure things I don’t know about). So I’m double hyped. Guys simplified the material and made it even more usable (I mean, I don’t know how geckos regenerate their skin material when it damages over time, being so delicate; I bet it uses a lot of complicated biochemical processes-but this material is cleaned to a nice degree just by using sticky tape?-that’s neat.

The applications for this in the trad climbing community could be great. In trad climbing, gear is placed in cracks and faults in the rock to catch a potential fall, but this isn't really possible currently on flatter surfaces with less cracks for gear placement. With this it could be possible to place gear on a flat surface, let it sit there while the climber climbs, and catch their fall if they do.
It would completely open up a whole world of harder trad climbs that haven't been possible due to lack of gear placements for protection.
You know my epiphany from this video? I always thought Van der Waals force was sort of a suction cup. You just taught me something new. Thanks Veritasium. Great, in=depth, dive.

@@Ildarioon that's what im saying. i read articles without taking the time to google the meaning of van der walls
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

I traveled to Brownsville, Texas to collect specimens off the glass walls of the airport terminal building. This was the point of entry into the US probably on imported fruit. We examined the toe of one under a microscope. So I knew of the toe pads in 1967 but did not have the Knowledge of how Van derwald forces worked here. It all makes perfect sense. When you pry one off the glass you had to push it toward its tail and it would just fall off."
what was your previous comment?
Huh, at least on PC, RUclips removes the part after the video ID (that includes the comment ID) when clicking the link. You have to copy the link and put it in the address bar manually.
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.
That's so cool! I love how diverse evolution is!
I feel like this would be relatively easy to make with the right setup. Even a desktop cnc fitted with an incredibly high quality blade should be able to produce this surface directly on the "part". It would require a lot of custom toolpath work, but that shouldn't be too difficult. Or to make a mold, some sort of thermoplastic could be held at a temperature that keeps it soft for cutting, then cooled to have a more durable surface. Wish I had more time to work on this. It would be a fun project.
Ya know… I’m sitting here again marveling at the fact that this is one of the only channels that continues to spontaneously make me say some exclamation out loud when something is explained. ❤

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.

Just for clarification all forces between partial charged atoms are called van der waals forces what he is specifically referring to is called London dispersion forces

I'd imagine eventually you could culture a big sheet of gecko foot skin cells in a life support medium and just separate sheet after sheet of the keratin(?) they deposit to get the real deal, or replicate the same molecular pathways using enzymes in solution inside like a collagen framework without needing real cells at all. Gecko feet make the stuff just fine, I'm sure before too long we can do whatever they're doing to get it.

Would love to see you try to climb with that.
I've heard of the attempt or idea at least of using the principle of how Geckos climb many years ago, but no one really knew how it worked as you mentioned so I'm really happy to see such a big step forward not only in the understanding but also application of this principle that was a mystery and challenge for so long.
Yeah but you heard the man. We can't make spatula.
Also, we need the man, so go climb a building yourself, please
@@mayn90s19 yet.
maybe in the future with more sophisticated technology we might be able to do so.
@lJ_K 3D printing will just get better and better, I think that might be a possible way to do it one day. Technology is amazing for sure.
Fascinating!!! Thanks a lot for sharing!!!!
Derek DEFINITELY needs to climb a wall, I'd love to see that
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?
Les bandelettes n'ont pas à supporter le poids de la voiture mais la force de traction et elles sont plusieurs pour se partager cette force donc elles n'ont pas besoin d'être très solide.
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.
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
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.
The object you climb would also need to support your weight.
fun fact, some geckos held on so strong during hurricanes that their arms elongated due to the high wind speeds. This actually happened recently.
They weren't motivated enough
"Never skip finger day, bruh." -some geckos
They need to train harder.
That must have hurt
@@KhanhDinh291 probably. Imagine looking like the gecko version of bigfoot.
I love this (and geckoes and insects with such surfaces under their feet). Incidentally, as well as under their feet, at least some geckoes have such a patch under the original tail (not the regenerated tail after losing the first one, having regrown the lost tail, they simply have to carry the new tail once it has re-grown).
A relatively simple concept, but it’s cool to see practical applications on a microscopic scale. I’ve been caught in a bad snow/ice storm and cut sipes into an old set of tires with a razor blade to achieve a similar result. It works well. If you don’t know this, as a tire rating goes from summer to winter rated the tread pattern will have more and more slices in the tread called sipes.
10:09 “PrOduce”
POV : when uncle ben makes Spider-Man suit
This is why i LOVE science even though im 13 its so hard to grasp but once you get even the tiniest grasp on it, it is AWESOME.
Amazing. We need more videos celebrating such heroes.
11:12 the researchers just cringing at the Gecko tape getting dirty due to blobbing on table.
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 RUclipsrs did it this way.
This is extremely interesting!! Thanks a lot
I watched this video for a school exam assignment. I found it very interesting to see what the researchers have achieved after studying geckos and how this can be turned into a kind of tape that can carry a lot of things or even a robot that can pull a car.
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!
It won't be, it was made more than 10 years ago, and it's still not on the market for some reason
As someone who owns two, geckos are fascinating creatures. It's amazing how engineering takes so much inspiration from nature to create innovative designs.
Do they sometimes give out little gecko-barks? I like the sound of that.
Greatly appreciated
I wonder how it could be used in the Medical Field!!!! This video is BRILLIANT,loved the info, I am wowed!!!!!!!
Very cool video. I recall a Mythbusters episode where the team was trying to do this in a duct and how clunky and loud their attempt was using magnets. This material probably would have been much more suited to the task.
11:45 how is that a question? OF COURSE WE WANT TO SEE THAT!
It's like asking a south magnet to repel a north magnet.
I remember seeing this when it was just a theory on popular mechanics! This was 25 years ago.. To see it as a material that can be reproduced and WORKS thats awesome. At the time it was just thel understanding of what kept geckos on walls. Now we're putting it on robots
I love how this video used a short as a trailer!!
I really appreciate this video. I've long heard about gecko tape and how it uses Van der Walls forces to "stick" but I've not yet seen a comprehensive description of its exact structure, how it is made, and how it is used. You do all of this clearly without the breathlessness and fluff that prior news spots have done. (Yet, your fascination shows and is infectious.)
A cool, fun video. Thank you.
big big yes to the van der wall force!!!! was looking for this comment :D
It’s actually substantially incorrect. Gecko mimics have been created without the structure present at all. The microstructure is not needed
You are the best at storytelling. You have a way to keep me interested in, what would otherwise be, boring topics.
Sometimes, I feel like I'm even involved
Well of course we bloody want a video where you climb a building with gecko adhesive!!! OHH maybe you could make a competition between you and some other people, who can climb the fastest, and what technique works the best!
This is freaking amazing.
Veristium basically went to this lab to read the poster they made. This is a testament to how useful and how well done that poster is.
3:13 Happy little Gecko, walking
🎶 Happy little gecko. What he do? 🎶 Happy little gecko. What he do? 🎶
I remember I watched a documentary on this about 9 years ago, now it's widely known. I love science
This reminds me of the phone book mythbusters episode where it took two tanks to pull two phone books apart that had their pages interwoven with each other. If I recall, the physics behind that is just simple friction, though I guess it would be the same forces applied here? It's not like the phone book pages were electrostatically charged, so I assume the force holding them together were also Van Der Waal.
Very interesting that the gecko evolved into having those nano structures. So so fascinating
What's interesting to realise is that nature does not have names for things or classification of sciences like we do. To nature, everything evolved up from atoms - whether inorganic chemistry, organic chemistry, mountains, lightning, the tidal bulge, living beings or star systems. It's the same laws, applied everywhere. We just need to figure out how they work in combination to explain a given phenomenon.
@@anandsharma7430 One generation of lizard got born one time and realized it has crazy good traction.
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.
@@TN-es7ei Either is a possibility, I'm all up for aliens doing genetic engineering. :P
@@TN-es7ei 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.
I have been working on similar projects for about a year and a half now mainly to stick things to other things in the pharmaceutical industry, so that we don’t use adhesive. My solution to making the exact copy of a gecko feet is to actually use silicone to mold a negative of actual gecko feet. And then a copy and edit paste until you have a surface that is large enough that you can create a metallic mold. Because there is no solution to making something that small other than nature itself. For example, bacteria have tiny, small little hairs that we could never manufacture, but we could copy it off of a bacteria.
Scientists seem to be relatively close to developing the ability to manipulate genomes enough to custom-build cells. So maybe, in near future, can program cellular "factories" to grow useful amounts of these nanostructures instead?
Thankyou for explaining this unique tech
This is just nuts good stuff and truly amazing
Great video! Thanks for creating so many quality videos over the years!
