Two Thai guys challenge each other at the net for a loose takraw ball.
Takraw is a form of volleyball in Thailand played sans hands involving a hard wicker ball and chest-high net. Amazing feats of athleticism are seen at the moments when the ball is set up to spike. The spiker generally does a modified back-flip that allows him to slam the ball with one foot while he's nearly in an upside-down position.
A takraw player back-flips and spikes the ball on the defender.
