A boy in a blue shirt, a girl in a white shirt, a man in a black shirt and black cap, and a goateed man in a white shirt stand next to an inflatable slide while a boy in a white shirt and jeans bounces downwards.
The four people screamed in horror as the young boy was hurled off the inflatable slide, flying through the air.
It is not implied that the people are screaming. Just because the boy is bouncing downwards, does not mean he is going down a slide, about to be hurled off into the air.
