                    HOVERCRAFTS
Hovercrafts are simple machines that hover over a layer of air. These machines or in my words its an automobile which can hover over any surface. It can be water, wetlands or even mine feilds.
this video is showing the situation                                                    https://youtu.be/qFnLi6OkWuc 

The technology is very simple the air above is pushed through holes below the hovercraft which exert pressure over an area below it levitates the craft. As the pressure is aplied over a larger area it do not need much denser surface to move on. 
Its a cool device awaits much more developments.
