This video starts out nice enough. Some kids are merrily playing in the water of an inlet in Hawaii. Nothing to see here, what on earth could go wrong?

Oh, wait a minute. Huge waves, strong currents, and sharp rocks combine to form a lethal combination.

These kids could so easily have been swept out to sea never to be seen again. Or dashed against the rocks, knocking them unconscious and struggling to stay afloat.

People have died doing this, but these kids look like they do this kind of thing regularly. The problem is as much as they may think they’re safe, the danger still exists.
