How does a hovercraft work?
Hovercraft use blowers to produce a large volume of air below the hull, or air cushion, that is 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.
How do you make a paper hovercraft?

How do you steer a hovercraft?
A downward-pointing fan can only blow air underneath, so hovercraft typically have one or more propeller fans on top of the hull, pointing backward to propel them forward. Usually, there’s a rudder positioned just behind each fan to swivel the air it produces and steer the hovercraft in the appropriate direction.
What is the definition of hovercraft?
