It's called grinding. It takes alot of practice, the basic grinds are 50-50, boardslide, 5.0, Smith. You have to Ollie onto it and move your board depending on the desired trick, it takes some people years! Some more advanced are Overcrooked, Lipslide, darkslide and Nosegrinds!
Hope I helped :)
same as you do on a skateboard
metal :)
A sheet of metal forming the bottom of something, e.g. a skateboard.
Cutting light gauge metal. I've seen these in 3 foot and 4 foot widths. Slip the metal under the blade and jump down on the bar. Some have been adapted with an electric motor.
An Ollie is a skateboarding trick. It is basically a jump while on a skateboard.
you just pop and slide your foot up.

Plastic? Ive never seen metal wheels
Yes even if it is a short amount of time in the water and is quickly put in the sun to dry it will ruin your skateboard deck
nothing it just rusts the metal
