Cappuccino Coast

Can you imagine swimming in the Cappuccino foam?
Well... All you have to do is to fly to New South Wales, Australia now!! :)
I wonder whether we'll get wet or not walking in the foam...
May be it's just like taking a bubble bath??

The shoreline north of Sydney is transformed into the Cappuccino Coast. Storms whipped the sea into foam, which swallows an entire beach and half the nearby buildings, including the local lifeguards' centre, at Yamba in New South Wales . The foam is so light that people could puff it out of their hands and watch it float away.

Scientists explain that the foam is created by impurities in the ocean, such as salts, chemicals, dead plants, decomposed fish and excretions from seaweed. All are stirred up together by powerful currents which cause the water to form bubbles. These bubbles stick to each other as they are carried below the surface by the current towards the shore. As a wave starts to form on the surface, the motion of the water causes the bubbles to swirl upwards and, massed together, they become foam.

"It's the same effect you get when you whip up a milk shake in a blender," explains a marine expert.
