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

3:53 - DIANNA!!! Serious question... Does the Intermediate Axis Theorem apply to the Earth's core?

I believe most would say "NO" as the assumption is that they believe the Earth's mantle, outer core, and inner core are spherical. The Earth's actual shape is an oblate spheroid (i.e., it's flatter at the poles and wider at the equator). This leads me to believe that the super-dense inner core, an oblate spheroid, could move about it's intermediate axis and, therefore, obey the Intermediate Axis Theorem, which would explain the shifting of the Earth's magnetic poles. Your video, combined with the videos below (see references) inspired my question to you... so what are your thoughts!?

P.S. Love your webisodes and keep up the crossovers w/ Joe, Derek, Michael, and the rest of the eggheads out there!
