Bakunawa is the new roller coaster debuting at Six Flags Great Adventure in Jackson and it’s downright diabolical. It is said to be the world’s fastest spinning roller coaster. It’s an upside-down launch, goes 100 mph, and is the world’s tallest spinning coaster, the world’s first floorless spinning coaster, and has the world’s longest stall inversion. All of this means every time you ride this coaster it is unique. Which is far more dangerous statistically speaking than a roller coaster.
