I took my daughter to a local ice skating show over the weekend and they had performances by a couple of synchronized skating teams. I was not even aware that this sport existed! I got home and immediately looked on the Internet to see what the "higher level" teams looked like. Considering how hard it can be for pairs of skaters to stay in syn, I cannot imagine how difficult it would be to keep 16 to 20 skaters in sync!! Watching the changes in formations is very interesting. Youtube has tons of video, unfortunately I cannot post the links here. If you are interested in checking it out some of the most interesting teams (that I saw) were: Rockettes (Finland), Team Surprise (Sweden), Haydenettes (US). There is also a talented team from Canada called Nexxice that won the most recent world synchro championships, but I to be honest their music selections were a bit off-putting to me.
