0 a device for removing corks from bottles, that consists of a handle with a twisted metal rod to push into the cork and pull it out -- （拔軟木塞的）瓶塞鑽，螺絲起子
Aircraft corkscrews down and crashes on the perimeter of the airfield.
The rear-gunners also maintained a watch for fighters and if warned the bomber pilots could pull evasive manouvres such as corkscrews.
The elements during the ride include two corkscrews, a pretzel loop, a top hat and an in-line twist.
After the brakes, there is a small drop followed by the interlocking corkscrews, the last two inversions of the ride.
Corkscrews are necessary because corks themselves, being small and smooth, are difficult to grip and remove, particularly when inserted fully into an inflexible glass bottle.
In this inversion, two separate corkscrews spin around each other; one turns riders upside down over the other.
They emerge in a dense group, corkscrewing upwards and counterclockwise, usually starting around sunset and lasting about three hours.
However, these laps often feature special track areas such as loops, jumps (including over tall buildings), slalom roads and corkscrews.
