'The Joker' coaster opens at Six Flags
Six Flags Great Adventure is introducing a new thrill ride over Memorial Day weekend.
The theme park's new roller coaster, "The Joker," opened to the public Saturday.
It lifts riders up a 12-story, 90-degree hill, takes them over a number of curves and flips them in their seats at the same time.
The ride aims to give people a feeling of weightlessness.
The ride is named after the famous DC Comics character.
