You really can swing all the way around
the bar. An Estonian sport called kiiking
is a form of extreme swinging that
involves doing a 360 around the spindle
of a gigantic wooden swing. Because the
feat gets more difficult as contestants
advance to taller swings, champions are
ranked by the largest loops they were
able to complete. The current world-
record swing is over 23 feet high. Source Source 2
