Cannon Ball Contest
American diver David Boudia took home the gold medal in the 2012 London Olympic Games by executing a near flawless two-and-a-half somersault with two-and-a-half twists in the pike position from the towering 10-meter (33-foot) platform [source: Coffey]. But can the dude cannon ball?
To perform a perfect cannon ball, one must leap from a diving board or the side of the pool and clutch both knees to the chest forming the shape of -- you guessed it -- a cannon ball. Unlike competitive diving, the goal of the cannon ball isn't to slip noiselessly into the water, but rather to create the biggest splash possible.
In a cannon ball contest, two or more competitors try to impress one or more judges with their cannon balling skills. Judges can rate competitors by biggest splash, best cannon ball style, or whatever random criteria they wish. Until cannon ball becomes an Olympic sport, there are no official rules.
