When we taught this to the class... I think we did good with the explaining and demonstrating part, for both the history and the rules of the game. However at the start of the game it wasn’t really good. People were jumping all over and fooling around, and they didn’t get the fact that we could TOUCH the rubber band (they were trying to jump "high jump" way), we emphasized that and after a while, people started to get it, and they could jump over the rubber band. I think we can improve by forming a line, so that people can take turns jumping and not “disturb” others by making the rubberband chain shake when they are walking over the chain or testing their jump. A piece of advice... Speak loudly, emphasize the fact that you can touch the yang, let people jump over in an orderly way and make sure people get what you're saying.
