The small ball is great fun. Flat thrown onto the water surface, he actually jumps just like a "bouncing ball" and may continue so easy to travel long distances. However, one should keep in mind that you bring enough space to play with the ball. Simple throw goes to the soft ball even with small children well, as it does not hurt, even with a direct hit but that the ball is really too bad. Thrown only at long range powerful flat over the water area shows what is meant by jumping over the water. Then the big kids have fun neat. But you should select either a lake or a pool in rainy weather as a playing field, as it may be sometimes 30-50m apart loosely and can still pass the ball well. Very clear water fun recommendation.
