London is set to unveil a new pool that is suspended 115 feet up in the air.
The 'Sky Pool' is an 82-foot transparent swimming pool stretched between the 10th stories of two skyscrapers in southwest London's Nine Elms neighborhood.
It also features a rooftop bar and spa.
One swimmer who got to test out the pool said it feels like you're "swimming" and "flying" at the same time.
Scheduled to open in May, you can check out more photos of the 'Sky Pool' here.
