AMAZING!!!Dolphins create and play with Air-bubble ’circles’

Dolphins and certain whales are known to blow bubble rings. Two ways of creating such rings have been reported: one way is by letting a ring out of their blow hole, the other by creating a water vortex ring and blowing air in the vortex ring. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-==-=-=-=- HOW TO DO THIS YOURSELF UNDERWATER: * Squeeze your lips to a small orifice. Keep it closed though. Your lips should look like being ready for a kiss, though a light one (not that wet smacker of your mother in law...). * Slightly increase the air pressure in your mouth. * Now very quickly open and close your lips so they pop out a very small amount of air. Abrupt closing is essential. The air shall really pop out. When all goes right, the air will form a ring. * Keep trying till you blow the nicest and smoothest rings and the dolphins are no longer ashamed of being a ring blowing mammal.
