The Stickiest *Non-Sticky* Substance

[@bdmlstanford]

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.

[@-dash.]

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?

[@Sumcrab]

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 :)

[@Tobi-kp1ie]

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

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 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.

Follow up to my comment about my grandfather, I sent him this video and he sent me this back 😀 "Thanks 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."

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.

It’s actually substantially incorrect. Gecko mimics have been created without the structure present at all. The microstructure is not needed

[@BM0NNZY]

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

[@anandsharma7430]

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.

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.

This is neat stuff. even just as a tape to stick to itself in a strip- in theory it could be used to wrap things, and then be released by a brief pulsed torsional shock.

[@aarashnavabi4749]

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.

[@Vaeldarg]

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?

How did they find out that it isn't friction, but van der Waals forces? Because the effect seen in the Video and the explanations would also apply to friction that is increased with shearing forces.

[@Yupppi]

You got me standing in awe with just the fact that the non-sticky tape sticks to surfaces depending on its orientation and holds very well judging by the objects you were hanging. Absolutely mind-boggling. There has to be a caveat for wide range use, hasn't there? If not, this will be perhaps the number one future technology. In my eyes it will be one of those turning points where you can reminisce how you saw history change in your lifetime.

[@meneldal]

You could use multiple directions in the structure to make it strong in shear on multiple axis, but there's no way to make it strong on the normal axis, though I guess you could always combine it with suction to get the forces going in the first place.

[@comicus01]

Yes there's a couple of caveats: it only sticks to something smooth, not rough, just as our fingers won't stick to glass, this probably won't stick to our fingers. I was impressed that one shot showed a robot on what appeared to be a brick wall, so maybe I'm wrong? I would hop so. 2nd caveat: it's very difficult to manufacture. Which they showed. I'm wondering if it would be more practical to simply raise geckos for their feet. Not nice to geckos, but hopefully they can also find a more efficient way to manufacture this gecko tape.

[@brrrrrr]

@@comicus01 problem: hard to manufacture known information: gecko has better version solution: put gecko on the bottom of robot feet or hands as grippers

It's basically like a cat's tongue. Rough in one direction, not in others. For instance, climbing a building, you have to be VERY careful not to have a strong sideways force or you fall off.

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.

[@newfinishautospa]

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.
