chute

A framework, trough, or tube, upon or through which objects are made to slide from a higher to a lower level, or through which water passes to a wheel.

On reaching the slip, the barrow was wheeled off the truck onto a scaffolding gantry built out over the wall, and the concrete tipped down a corrugated iron chute on to a steel plate.

A waterfall or rapid.

A pen or passageway to constrain the movement of an animal, such as livestock being loaded for transport; the pen in which an animal is confined before being released in a rodeo.

An extension to a straightway on either the home stretch or the backstretch, to avoid having a turn at the start of the race.

A parachute.

Yet the initial IMF rescue plan was far from the parachute which it professed to be – the chute did open briefly but only for it to "Roman candle", the hapless victim left to plummet to earth with a sickening thud.

At first, Cyclops's chute began to Roman candle , but in another moment, it popped.

A spinnaker.

To parachute.
