Flying the kite downward bring both arms behind you and before the nose-diving kite reaches the ground, throw both hands forward (just like a reverse turtle). The kite will then float on it's belly. This works best in light winds. Some kites like fast arm-throws, others like slightly slower ones.... Another way to try it (if the previous one doesn't work for you) is to fly the kite downwards, first extend both your arms, then pull back both arms hard and release abruptly to kill the kite.
