Yang Chen, do you know why we are at the swimming pool? But we aren't just talking about swimming. We are going to be talking about the Olympic sport of synchronized swimming. Yes, we do. Synchronized S-Y-N-C-H-R-O-N-I-Z-E-D swimming, Yang Chen. You know, the sport that combines swimming, gymnastics and dance. So why do you ask? How can you say that, Yang Chen? Those swimmers work really hard to get their routines in perfect unison. It is a very demanding sport, requiring strength and artistry. Come on, Yang Chen. It is like ballet in the water. Well, then I guess I'm just going to have to show you how demanding a sport synchronized swimming is. Let's try to synchronize some of our moves, Yang Chen. Yes, we do, Yang Chen. OK. Now raise your right hand in the air, raise it up. Good, all right, good. Now reach down and touch your left foot.
