I only just spotted it! Your comment reminded me of a competition we used to have in a Sunday newspaper, if I remember correctly, years back. It was an image of a football match, with the ball removed. You had to guess where the ball should have been. It was great fun and you could win some serious money - again from what I recall!
@jamibann thats exactly what went through my mind when I saw the ball in the water. It could have been a "spot the ball" competition, without the footballers haha!
