   Skateboarding is hard.

   When I was about 10, I broke my first skateboard by riding it into a
   ditch. A decade later, in college, I broke another skateboard within an
   hour of owning it (surely a record) in a short-lived attempt at doing an
   ollie. (Surprisingly, the store accepted a return on that board even
   though it was in two pieces.) Then I was gifted a really nice,
   high-quality skateboard. The first thing I did with it was ride it down
   a big hill, a valiant but ill-fated adventure which ended with me
   jumping off the skateboard, rolling down the grass, and arriving scraped
   up, deflated, and rather disoriented near the entrance to my college
   cafeteria. (In my defense, the wheels and ball-bearings on that
   skateboard had been pre-lubricated to minimize friction, and why would
   anyone do that, that's just crazy.)

Looks to me as if the skater is simply positioning his feet so that 
they'll meet the ground at the same time. The skateboard, being 
underneath, and not very massive, just has to comply.

However, it will never be known whether this understanding means that I 
can now perform an Ollie.

Only one way to find out ... in the name of science!
