In all my years blowing bubbles in the bath tub, I have never been able to achieve anything like this! It remained a coherant mass about six feet across as it rose leisurely to the surface and then errupted, hissing as it dispersed.
It is thought that whales use what scientists call "bubble clouding" to confuse the small schooling fish that Humpbacks feed on. The fish clump and flee the bubble, forming a delectible mouthful for the whale to scoop up. In the Pacific, humpback whales are known for making bubble nets, a ring of small bubbles that look like a cyclone as they rise to the surface. Atlantic humpbacks blow these clouds. It would be fascinating if the Atlantic and Pacific groups learned the others techniques.
