the apparently universal language of footbag
In Laos, the boys play a game that looks like a cross between footbag and volleyball. They kick a small wicker ball back and forth over a real or imagined net, performing various tricks. The main rules are, you can't touch the ball with your hands, and you can't let it hit the ground.
In Vietnam, young people play a game that looks even more like footbag. They form a circle and kick a small cork-shaped object with a feather poking out of the top. They pass it to each other in the air and perform various tricks. The main rules are, you can't touch it with your hands, and you can't let it hit the ground.
