1. It's foot positioning is slightly different from the ollie's.
Your back foot still goes on the tail of
the board. The front foot goes just behind the screws, like
the ollie, except your heel has to hang off of the heel edge.
2. Now pop the tail(back) of your skateboard down. Instead of just sliding the front foot forward,
slide it off of the heel edge also.
3. Try to stay centered above the board as it spins under your
legs. Be sure to stay well above it.
4. As it finishes the final turn land on the top and roll away.
