Cord snaps on reverse bungee ride
(Sunday, May 7, 2006) - At Clarke Quay in Singapore, a reverse-bungee catapult ride known as G-MAX was shut down after a bungee cord snapped. No one was injured. The ride consists of two 100-foot-high steel towers with a bungee cord connected to each. The cords are stretched toward the ground where they are attached to a caged steel vehicle in which riders are seated. The cords are then released, sending the riders on a high-speed vertical launch 200 feet into midair. The cable snapped just before the vehicle was released.
