Disregard BK, I dont know where he gets off. Im pretty positive that I know how to do a corked 5 but Ive never personally thrown one (yet..mmmm summer slush), so I wont try and explain it, I dont want you to get hurt because I left out an important tip. But to put you on the right path (do this on a tramp), imagine popping off a jump, start spinning and 'look back at the lip', thats where you cork it, youll be on one axis until you rotate 360, now you should be thinking of coming out of the cork and putting your feet down on a different axis. Did I just negate my previous statement? Fuck it. Anyway try it on a tramp/diving board first because you can mess yourself on this trick if you dont do it right.
