Here a container filled with a suspension of neutrally buoyant polystyrene beads and fluid is rotated. As the container rotates, a thin layer of fluid and bunches of particles get drawn up onto the wall by capillary forces capable of holding the particles in place even if the container stops rotating. The density and patterning of the particles on the wall depends on the container’s rotation speed and the volume fraction of particles. (Video credit: J. Kao and A. Hosoi)

    This is based alot on the same principle that HNMR’s use. SO COOL. I worked in a fluid dynamics lab for a few weeks...

    Capillary action...just like Rodney Dangerfield, it doesn’t
