We got it!

This is a traditional Cambodian game – krama tossing. The rules are to wrap a heavy object in a traditional Cambodian krama, and the boys' and girls' teams stand at a certain distance from each other, throwing the packed krama to each other, and the other team must catch it. If it falls to the ground, the whole team will be punished by performing a traditional Cambodian dance. This picture shows the boys' team desperately catching the krama to keep it from hitting the ground.
