I don't know exactly dance pants work but this is how it looks. There are small iPod speakers that you can put in your ear. This is when the pants part comes in: The speakers are motion activated so they only play music when you are running. The way they do this is there is a mp3 player in the hip that is controlled by the feet. Near the feet there is kinetic energy (and no, I do not know what that is). Somehow that kinetic energy makes the mp3 player play and you hear music.(But only if you are running). I think this is a torture device. Why would people want there music to stop when they stop running. It takes the point away from listening to your iPod while running. I do understand that maybe it encourages you to keep exercising, but c'mon, who would really buy this. Not me.
