X Scream is one scary experience. X Scream is a new generation of extreme thrill rides, playing on the passenger's primal fear of falling. It may just be the ultimate thrill ride in the world. Passengers are loaded into an eight-seat car on the high-tech teeter-totter and hoisted high into the air before the track dives at a 30-degree angle, taking the car and your nerves with it. After reaching speeds of 30 mph, the car jerks to a sudden halt at the end of the track, with nothing but 900 feet of air between you and the ground. X Scream might just be one of the ultimate thrill rides in the world.
