You have to know how to Indy grab before you do this.
Ride up onto a ramp and when your about to ride off (NOT OLLIE, RIDE) grab the board. Then hold it and ride off the ramp. When your going back down to mother earth gravity will do the rest just let go. When you do this trick do it fast it seems to work and look better that way.
Good Luck!
