A Yummy Whipped Ocean

Last Year, the shoreline of Sydney, Australia became a suddenly whipped froth that was caused by impurities in the water and powerful currents. As insane as this may look, it's definitely true! Onlookers who witnessed the event decided that since surfing and swimming were obviously out of the question, playing in the foam was a fantastic alternative! I wonder if anything like that has ever happened again? Furthermore, I wonder if something like that again will happen in Sydney, Australia? I'm betting the kids certainly wouldn't mind!
