Abstract
A diver diving in a swimming pool can suffer a belly flop: he collides violently the water. Skipping sones on the still water of a lake, results in a collision of the stone with the water. We address this problem assuming the collisions are instantaneous and introducing the deformation of the system solid fluid. The incompressibility of the fluid results in a percussion pressure. It is responsible of the pain of the diver in a belly flop.
