Zero-G "Heartline" Roll – Bizarro, Six Flags Great Adventure
The zero G-roll or "heartline" inversion is one of the signature elements found on several of Bolliger & Mabillard's steel coasters. The Medusa roller coaster at Six Flags Great Adventure
, now renamed Bizarro
, has seven-inversions during the almost 4,000-foot long, three-minute ride.
