KNOWLEDGE DRINK

Friends do you know that there is a special type of vehicle which can travel over water, mud, ice, land and any other surfaces with equal efficacy.

 It's a HOVERCRAFT, that's also known as an AIR-CUSHION VEHICLE or ACV, is a craft capable of travelling over land, water, mud or ice and other surfaces.
Hovercraft use blowers to produce a large volume of air below the hull that's slightly above atmospheric pressure. The pressure difference between the higher pressure air below the hull and lower pressure ambient air above it produces lift, which causes the hull to float above the running surface.
They are now used throughout the world as specialised transports in disaster relief, coastguard, military and survey applications as well as for sport or passenger service.

>हॉवरक्राफ्ट (Hovercraft) हवाई गद्दों वाला एक ऐसा वाहन है, जो जल और जमीन के साथ-साथ बर्फीली सतह तथा कीचड़ पर भी आसानी से दौड़ सकता है। इस में एक बड़े पंखे से हवा की एक गद्दी तैयार की जाती है जिस पर यह हॉवरक्राफ्ट तैरता है।
