It was as if someone had poured tons of coffee and milk into the ocean, then switched on a giant blender.Suddenly the shoreline north of Sydney were transformed into the Cappuccino Coast.
Foam swallowed an entire beach and half the nearby buildings, including the local lifeguards’ centre, in a freak display of nature at Yamba in New South Wales.
One minute a group of teenage surfers were waiting to catch a wave, the next they were swallowed up in a giant bubble bath. The foam was so light that they 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 churned up together by powerful currents which cause the water to form bubbles.
