Why this trick should be IMPOSSIBLE ft. Rodney Mullen - Skateboarding Science

Great Video! Rodney Mullen is the GOAT imo.

Another great trick to look into which doubles down on this intermediate axis spin concept is Ryan Williams Scooter/BMX trick where he and his scooter/bike both spin about their intermediate axes in opposite directions while like 40 feet in the air traveling at a decent speed. Although having said that I wonder if the forward momentum lends some stability to that rotation.  Either way it's quite impressive to watch and he has a lot of similar tricks that use intermediate axis spin.
