How do you do it?

Are you trying to drown me over the whole america/scotland argument?

I can't wait to learn it, then impress the nearby kids and have our Life Guard finally do some saving.

That cant be real! No way!

Looks real but the way the air bubbles behave seem to defy the laws of physics. How do they stay cohesive?

They stay cohesive cos of the laws of physics ;]) My dad used to do it when he was a dive trainer and a lot of divers do it to impress the chicks. Helps if you know how to blow smoke rings.

I agree with William. It was all pretty good until the one ring went inside the other. Meh, it's TV. anything's possible on TV.

Wiki Wiki:

A bubble ring is an underwater ring vortex where an air bubble occupies the core of the vortex, forming a ring shape. The ring of air as well as the nearby water spins toroidially as it travels through the water, much like a flexible bracelet might spin when it is rolled off a person's arm. Some scuba divers can create bubble rings by blowing air out of their mouth in a particular manner. Long bubble rings also can form spontaneously in turbulent water such as in heavy surf. Bubble rings and smoke rings are both forms of vortex rings, and are sometimes studied in the field of fluid dynamics. Dolphins and humpback whales have also been seen to create bubble rings.
