Improv Everywhere's 10th Annual MP3 Experiment Was Fake Mob Of Tourists (VIDEO)

Improv Everywhere's annual "MP3 Experiment" is an event where participants download the same MP3 file with crazy instructions and press play at the same time.

This year's experiment gathered more than 7,000 participants, instructed to dress as tourists and mingle amongst the real tourists at Manhattan’s South Street Seaport.

Participants did everything from crawling on the ground to handing out dollar bills to unsuspecting strangers.
