When I was little there was a pool store nearby that had an actual pool in the front, and mirrors on the building so that the pool reflected out to the road, and I thought there was a sideways pool, and I used to wonder how they kept the water in. Finally one day I decided they had glass over the side. I only figured it out a while ago
