This summer has been so hot and humid, and I can't think of a better way to cool off than jumping in a swimming pool. Check out this infinity pool - nearly 7 stories high!  It's part of the Sands Sky Park at the Marina Bay Sands Hotel in Singapore. According to their FAQ, the pool is accessible only to hotel guests. The general public can purchase tickets to visit an observation deck and part of the swimming pool deck. I'm used to seeing infinity pools overlooking a beach or an ocean, what an amazing experience overlooking the city!  Where is your favorite swimming pool?
