A boundlessness pool is a reflecting or pool, where the water streams more than at least one edges, creating an enhanced visualization of water with no limit. Such pools are frequently planned so the edge seems to converge with a bigger waterway, for example, the sea, or with the sky.
A swimming pool, swimming bath, wading pool, paddling pool, or simply pool is a structure designed to hold water to enable swimming or other leisure activities. Pools can be built into the ground (in-ground pools) or built above ground and are also a common feature aboard ocean-liners and cruise ships.
In-ground pools are most commonly constructed from materials such as concrete, natural stone, metal, plastic, or fiberglass, and can be of a custom size and shape or built to a standardized size, the largest of which is the Olympic-size swimming pool.
