Ever wonder how fish and sea mammals really swim?
This video explains in simple terms, easily understood, what every good river kayacker-boater already knows. It is all about eddies. The waves in the ocean do the same thing, but a different plane.
Understand how fish swim & kayakers go up stream, then visualize how UFOs sail and functionate the action of gravity. The original UFOs don't utilize "anti-gravity," just as whales don't use much energy to get squirted through and by wave action!
