Quick answer：

An infinity pool is a swimming pool that has one or more sides that appear to extend to the horizon. These pools are designed to give the illusion that the water spills over the edge, creating a seamless blend between the pool and the surrounding landscape. The '45-story infinity pool' likely refers to an extremely tall and impressive infinity pool, possibly located in a high-rise building or a luxury resort. Such a pool would offer breathtaking views and a unique swimming experience.
