The Mp3 Experiment of this year was at Roosevelt Island in New York City. In this Sixth Annual MP3 Experiment, over 2,000 people of all ages have joined the event. They synchronized their watch to the clock on the instruction page, downloaded the mp3, wore a red, blue, yellow, or green shirt, and then traveled to the island. At exactly 4:00 PM, everyone would press play from wherever they happened to be on the island. Check it out after the break.
