Super Hydrophobic Surface and Magnetic Liquid - The Slow Mo Guys

  • Published on Jan 6, 2014
  • Gav and Dan are in the GE lab using nanotechnology to show you cool liquid physics at 2500fps.
    The first experiment shows a superhydrophobic surface that GE has been working on. Surfaces like this can be useful in aviation and wind power to reduce ice build-up or for self-cleaning applications. The surface traps a layer of air using its nanoscopic structure, which prevents water from sticking.
    The second experiment also demonstrates how the nanoscale differs from the macroscale, this time with iron filings. Iron filings at the macroscale can be easily distinguished from the liquid they are in. When reduced to the nanoscale, magnetic nanoparticles can behave like a liquid magnet. Gav and Dan demonstrate this by showing magnetic liquid flowing upwards against gravity towards a magnet.

    Ahh, good ol Slow Mo Guys. Back when it was the good times, with two friends having fun to create cool videos that made you think about the world and physics. Before the painful scripting and stage acting of large scale crews that would clean up their destruction-for-no-reason projects, paid for by studio sponsors. Bring back the old fun videos....
    Either way, Thanks for this video, chaps!

      If we want to sided it up at all, but yeah instead you give us ten seconds of slow motion and then jump cut or speed up to the end

    The liquid one is rather blurry tbh. I would have liked to see how the material repelled the fluid...instead of the fluid just being repelled. The iron liquid was super dark also...so, yeah. This was a rather disappointing episode.

    You guys should do the same thing with the ferris liquid again but the test tube surrounding the magnet should be made frome a hydrophobic material so the fluid bounces off and around the tube.
