Up, up, and awaaaaaaaay!!!!
再高,再高,再……啊啊啊!!!!
The
mechanics of
bungee jumping are well known. The jumper, wearing a
harness attached to a long,
elastic cable,
leaps from a
platform high above the ground. As the jumper
plunges _(1)_, his or her fall is slowed by the
springy bungee cable, which causes the jumper to
bounce up and down like a
yo-yo before being lowered
gently to the ground.
A reverse bungee operates on the same principle, but
turns it on its head. _(2)_ the bungee jumper starts high, the reverse bungee riders start on a ground-level platform. The riders are
strapped into a
capsule _(3)_ by elastic cables between two
telescopic towers. The capsule is held to the platform by an
electromagnetic switch, and the riders lie back and watch the towers _(4)_ higher and higher, which
stretches the
bungee cords.
When the towers have reached their _(5)_ heights and the cables are at their
tightest, the ride operator
flips a switch to release the capsule. Like a rocket being
launched, the riders and capsule are
hurled skyward _(6)_ speeds close to 200km/h before being stopped by the twin bungee cords. Once the trip ends,
gravity _(7)_ and the riders fall back down to Earth and are stopped again by the elastic cords before hitting the ground. After a minute or two of bouncing, the riders are lowered towards the ground, shaken, but often wanting another ride.
