    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.

    I hope one day this technology is adapted as plasters/medical tape.

    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 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!

    Would love to see you try to climb with that.

    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.

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

    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.

    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.

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

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

    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?

    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 Clip-Sharers did it this way.

    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!

    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.

    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

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