howercraft can move on rough surface
The Advantages are that Hovercraft can fly, or more suitably, hover over water and land, can go over rough terrain and does not pollute as much as cars.
Hovercraft
That would be a hovercraft. However, hovercraft are not really boats and can travel on both land and water.

easy because they are slimy.
How is friction cut down in a hovercraft? This is done by hovering over the surface Why is friction cut down in a hovercraft? Because the surface of the hovercraft is smooth
because the wet surface makes it slicker so there slimy slick bodys can move 0ver faster
