Abstract: The present invention provides a novel system and method of covering a pool and making the pool invisible. The present system comprises a flat board and at least one lifting device. The board has sufficient size for covering the pool and is made of rigid materials so as to be able to bear heavy weight. The lifting device includes two parts: a movable part and a fixed part. The one part of the lifting device is fixed on the ground or somewhere in a building near the pool, and another part is joined to the covering board. The lifting device can vertically move the horizontal covering board upward or downward and keep the covering board always horizontal. When want to swim, the users only lift up the covering board, and when want to BBQ, they only lower the covering board to cover the pool. Once the covering board reaches the top of the pool wall, the pool becomes hidden and invisible. The users can do some activities and put something on it even on the lifted covering board as on the floor or on the ground.
