Takraw is named for the rattan ball it was once played with—these days that ball is woven from thin plastic strips. It’s light and hollow, a little bigger than a grapefruit; it may be kicked, kneed, head-butted, or chested, but never thrown. As it isn’t especially bouncy, it’s the players who must be elastic, contorting themselves into sideways splits and aerial spin kicks to keep the ball in play. Most players have been honing these moves since childhood: takraw is a core part of Thai gym classes.
