    I read a long time ago, that researchers that need to capture geckos for study will build a trap out of a large sheet of teflon it that will funnel them into a container

    “…a Tefal frying pan, that is to say, a pan made ​​of Teflon…”

    WRONG. Such a pan has a Teflon coating only.

    By the way: Teflon is a thermoplastic polymer and was found in 1938, long before even the A4 rocket – 20 years prior to NASA.

    Huh, I wonder how this scales down– if spiders & flies would have the same problem.  I mean, same fundamental forces, right?

    • theophrastvs says:

      if i recall correctly (and if i don’t someone here will call me foul names) “spiders & flies” use a combination of claws and stickiness (semi-liquid) to find a sort of “rock climber’s hold” on the surface (which is much easier when one’s mass is so relatively small); whereas… (it’s a good day when one can use a ‘whereas’)… geckos use a very different method of adherence involving gazillions of tiny hairs (or hair like projections) which interact with Van der Waals forces … electrostatic attraction at the atomic level.  Someone else, ((you reading this perhaps)) can explain how Teflon™ can reduce the effectiveness of such forces (probably related to the dielectric properties of PTFE, maybe)

        Maybe this is dependant on the type of lizard, but Bearded Dragons (an example of which can be seen in the above video) just use their claws as far as I’m aware.  Your explanation sounds much fancier though, and may well be true for Geckos (for which this is not).

    Once again, science beats nature. 

    Ball’s in your court, evolution.

  5. That’s a baby Bearded Dragon btw, not a Gecko!

    Awesome (and very friendly) little guys.

    This is actually quite an important detail, as their climbing techniques are completely different.

    Unless of course I’m mistaken and this is a particular type of Gecko that looks exactly like an infant Beardy.

      It’s a gecko. Look at those rounded toes.  Tarentola mauritanica maybe?

      • Lyle Hopwood says:

        It is a Tarentola mauritanica. A Moorish gecko.  You are correct.  I’ve seen many of them, although I’ve never made them attempt to run up a non-stick pan. 

        I have seen my Day Geckos unstick and fall off the glass when I’ve been spraying  their tanks with water though. They look very embarrassed when they do that.

    So non stick pans reduce sticking? Science!

    What happens when you do this with a Jesus lizard?

  7. trieste says:

    In the next section of the french video we see how difficult it is for the gecko when olive oil and a little garlic is added and the gas is turned on.

    I still don’t want to buy insurance from one.

  9. Robert Cruickshank says:

    The video is too short to add Yackety Sax to.   Reshoot, please.

  10. Boris Mohar says:

    The pan wasn’t hot enough.

    We will next try to answer the question: What happens when an irresistible force meets an immovable object?

    How long before Tefal steal the video for an advertising campaign?
