Have the youth stand in a circle. Then everybody claps in a rhythm: clap, clap, clap-clap-clap, clap-clap-clap-clap. Then you say, let’s wa. One person says “wa”, directing his hands as if he was praying, then pointing them towards any person. That person says, “Wa” and lifts their hands up above their head. Then the people on the sides of that person put their hands together and chop that person (not too hard!) in the side, and say “wa” together. After they do that, the person does what the first person did, and points his hands at someone else in the circle, saying “wa”. And then the process repeats. If anybody misses the rhythm they are out and step out of the circle. It can be a very fast-moving game, but do it slow first so people get the hang of it.
