MP3 Flash Mob

The 2013 MP3 Flash Mob is Coming on Monday, Oct. 21!


Here are the full details for The Mp3 Flash Mob. Please take the time to read all of the instructions on this page.

Please note: This is a participatory event. We encourage participants to leave their cameras at home and have fun participating. Let’s all enjoy the moment and resist the urge to document! Don’t worry, we will have a crew taking photos and video for all to see.

Date: Monday, October 21st
Location: McKeldin Mall, on the grass in front of McKeldin Library
Time: The event will begin at 4:00pm — press play on your MP3 player right when the person in the Green Morphsuit jumps onto the grass on the mall after charging out of the doors of the library.
Wear: Wear a UMD shirt. 
Bring: Bring along a pair of sunglasses for later.


  1. Download the Mp3: DOWNLOAD HERE
  2. Save the track onto your mp3 player (iPod, iPhone, etc.). If the track opens up in a new browser window, you can either go to “File > Save Page As” or right click on the link above and choose “Save As” and save it on your computer to transfer it to your music player.
  3. Do not listen to the track.
  4. On Monday, Oct. 21, meet on McKeldin Mall on the grass in front of the library wearing a UMD shirt with your sunglasses handy for later in the flash mob.
  5. At 4pm, look for the person in the green morphsuit running out of the front of the library. As soon as this person jumps onto the grass on the mall, hit play on your device so everyone is listening to the same track at the same time.
  6.  We will be using the time below to determine when the person in the green suit will jump onto the grass. Bring a watch with a second hand (or your phone if it shows the seconds) and sync it up to this time:

Frequently Asked Questions:

Say what now?

If you’ve never heard of an Mp3 flash mob, check out Improv Everywhere’s great examples: http://youtu.be/Wwv_QLiDceg

Can I use my iPhone?

Yes, but if you use an iPhone, be sure to put it in airplane mode so you don’t get interrupted by a call. 

Should I listen to the track beforehand?


Can I listen to the track beforehand?

You really shouldn’t. Sure, there’s nothing we can do to stop you, but to really get the full experience of the event, you shouldn’t listen to it. It will spoil most of the fun. We know it’s hard to resist. Be strong.

What if I get to the event late?

Press play at 4pm wherever you may be, and hurry up!

What if I don’t press play at exactly the right time?

If you can tell you are significantly off, feel free to glance at a neighbor’s device and try to sync back up to the correct time. You’ll have more fun if you’re more in sync.

Can I take photos or video?

Please refrain from taking photos during the experiment. We will have plenty of photographers covering the event, and you’ll have more fun if you’re not taking photos. We take care of the documentation; you take care of the fun!

I’m coming with some friends. Should we all start in the same place?

You can, but try to spread out so it looks like you aren’t together. The experiment will work best if there are a few other participants in your area, but not so many that it’s super obvious you’re all together.

Do I have to RSVP?



This is the video for the 2012 MP3 Flash Mob here at the University of Maryland. Participants downloaded our MP3 ahead of time, loaded it on to their iPod, iPhone, or other listening devices, and met at Hornbake Plaza just before 4pm on Monday, October 15th. Right at 4pm, a few balloons were released from the center of the Plaza. As soon as they were released, everyone hit play on their devices. The MP3 told them what to do from there!

The entire concept, from start to finish, was the work of the students of DCC 105.
