From Popular Science -> Zero Gravity Roller Coaster

Is this really any different from Superman @ SFMM?
Open is better than enclosed.
Scrape up 50 Million and we can find out.

El Toro and Nitro have more air-time, and cost less put together!

No moving around...

Pas­sen­gers would enter the coast­er through gull-wing doors, face forward,
and sit upright, six to 16 to a car. They would buckle into simple two-point re­straints,
but the belts would be kept slightly slack so they would have room to rise out of their
seats. Once aboard, they could re­move from a small stand in front of their seats one of
sev­eral teth­ered “sci­entif­ic packages”—a cup filled with wa­ter, a ball, a gyro­scope. In
addition to expe­ri­enc­ing weight­lessness, they would be able to observe how the se­lected
object changed prop­er­ties in ze­ro gravity. The cars would also be out­fitted with drains.
Should the ride live up to its nau­seous namesake, at­ten­dants at the unloading stations
would be ready with hoses.

Moving around.

No it's way cooler than El Toro!
