A hovercraft is a machine that rides on an iron-cushion. It looks like a funnel on a platform. It can go smoothly over deserts or over the sea and it climbs easily up ramps and slopes.

A hovercraft carries large number of passengers over both land and water. It can be used for pleasure trips or for transport.

To make the hovercraft move, a part of the air, which is driven by a powerful engine, is funneled off into jets on the deck. To make it go forwards, air is blown backwards; to make it go backwards, air is blown forwards.
