The design for a new, 570-foot tall roller coaster called Skyscraper has been unveiled this week in Orlando, which, when complete, will be the tallest in the world.
The animated video shows the cars twisting around and making their way up a massive white tower before plummeting back down to earth at speeds up to 65mph.
And there's no "down time," says US Thrill Rides president Michael Kitchen, the company behind the project.
Construction will begin in 2015, and the ride is expected to open in 2017 as part of a new $200 million Skyplex entertainment complex.
The tallest roller coaster at present is Kingda Ka (456-feet tall) at Six Flags in New Jersey.
