funny part is at the end when the jelly gets spun all the way to the surface and the ring stops, it just sort of "unfolds" and starts swimming away like, "what the heck was that". I didn't have enough gif length to show the whole thing though
Sort of like blowing smoke rings with air, underwater. Dolphins have been known to do it for fun while playing. This particular ring must have been made with a pretty strong burst of air for it to have been so strong.
