JACKSON - 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.
