There is a YouTube video of synchronized swimmer Mary Killman
performing what is called a Rocket maneuver to the song "Johnny
B. Goode" as part of her final solo at the 2011 synchronized
swimming world championships in Shanghai. Killman, who will
compete in this summer's Olympics, says it is one of her
favorite figures, and she can do some of the highest Rocket
maneuvers worldwide. Submerged, laying on her back, with her
legs held straight above her she forms a perfect floating right
angle. Gracefully she moves towards the surface, almost like an
illusion as if something or someone is pushing her up from
below. Suddenly she bursts legs first, kicking high up and out
of the water, flips over and emerges again arm raised like she
is now being pulled up from above. Synchronized swimming, or
synchro, as it is often called, is a unique, beautiful hybrid
form of swimming, dance and gymnastics. Swimmers are often
vertical and upside down with their legs above the surface,
performing spins, splits and other movements
