Zero G roll
From Wikipedia, the free encyclopedia
A zero G roll is a roller coaster inversion found on Bolliger & Mabillard inverted, sit-down, and floorless coasters and on Vekoma inverted coasters. On inverted coasters, this inversion is alternately called a "heartline spin" because its center of gravity is placed on the center of the rider's heart. On sitdown and floorless coasters, it is alternately called a camelback twist. The name for the roll comes from that fact that the rider feels a zero g-force, giving the feeling of weightlessness.
Essentially, a zero-g roll is a hill with a 360 degree twist in the middle.
