Southern California design firm BRC Imagination Arts has conceptualized a zero-gravity roller coaster designed to give riders a sustained feeling of weightlessness. The ride is modeled after NASA's Vomit Comet, the high-altitude airplane used to train astronauts.
The zero gravity roller coaster would shoot riders straight up a right angle à la Six Flags Magic Mountain's Superman: Escape from Krypton. Riders would be buckled in, but not too tightly so as to restrict movement. There would also be a goodie bag of sorts for them to play with during the ride. The bag's contents (water, a gyroscope and a ball were listed) are meant to show riders how gravity affects certain items. BRC Imagination Arts says that the roller coaster could seat between six and 16 and that it would cost $50 million to build.
