I agree with Tate - watch the crowd, especially those across the court. those farthest away show no reaction when the whale appears. And others are clapping way before it's over. I would also expect to see a lot of kids in the group in front ducking when it looked like the water was coming towards them, but instead most of them are looking off to the side, and paying no attention to the whale. Still, it's very very neat to watch!
