If you're ever in Shanghai make a visit at Holiday Inn located in Pudong Kangqiao and snap a photo of this swimming pool that is 24 stories above the ground. It looks so crazy to be true but according the website below this hotel & swimming pool does exist!
On the 24th floor of the Holiday Inn hotel, there is a "one of a kind" Swimming Pool that is 30 meters long and is on the edge of the hotel! What's unique about this swimming pool is that there is a glass underneath the pool. When you're swimming in the pool, you can look down at the bystanders, cars and everything underneath.
Would you dare swim in a pool that has a glass bottom? What if a bunch of people jump in the pool? The glass may shatter perhaps?? I would so not trust the pool... 24 stories HIGH, that's crazy, eek!
