My GF showed me a 10 minute video of synchronized jumprope that a high school group put on for a military base. When it first started I thought it was pretty boring, but as it went on it was pretty clear the young women doing it had a huge amount of talent and skill, some of the things they did were just unbelievable.
OK - I didn't know what to expect ... that was great! I had to watch it several times. I wonder if that is something they came up with or if it's something that has been around for a while. Either way, they executed it perfectly.
