Then land it. Just like a kick flip except push on the side from underneath. Pull out your hand so the board does a backflip. Then land it. It's easier than it sounds.
Grinds are easy.
Just ollie up onto a rail such as pen or pencil or something like that and slide across it. A description of the grinds are below. When you grind with the grip tape down. When you grind on the board with the 2 trucks on either side of you. Same as tail slide except on the tail.
