Dolphins and air bubbles

  1. Sep 12, 2014 #1

    I apologize in advance if this is the wrong section, it seemed the most appropriate

    Dolphins are able to produce rings of air which seem to counteract buoyancy by rotating ( I'm assuming rotation )


    How and why is this true ?

    They don't counteract buoyancy, they are held in place by a whirlpool - and only for a limited time.

    I am moving it to physics, it fits there much better.
