Riders get a very cool feeling as they fly through Zero-G roll on The Great White roller coaster at SeaWorld San Antonio. Zero-G rolls are an inversion where the roller coaster track is twisted 360-degrees as it gains and then falls in elevation. The result is the feeling of weightlessness, hence the words zero-G in the name.
