Brief
Description: The pen is rotated in a stationary slot (usually learned
in 23 first) by moving the fingers holding it slightly. The push is
usually the ring finger being moved slightly inward while the middle
finger is held relatively stationary. The ring finger is then pushed
back to its originl position in order to complete the rotation. This
trick may be done repeatedly very fast to look somewhat flashy to
non-PSers. This trick is also not very difficult but possibly the
hardest to understand fundamental and it is therefore encouraged that
you look closely at the links below to help you understand.
