From what I understand, the water would spray out if it could, but there's not enough room, so the force instead pushes the ball up to give more room, but the engineer tailored the forces just right so that once the ball is lifted, the force that would have made the water spray out is already used up, so it doesn't spray. There's only enough force to spray or lift, not both.
